  • NAASC Statement on Harassment and Discrimination (October 11, 2021)

  • We stand with our colleagues in the Maize Genetics Cooperation in supporting targets of harassment and discrimination, and renew our pledge to uphold our code of conduct at ICAR meetings to prevent anyone from experiencing these harms.
  • While current accusations against a member of our community are being investigated and the facts may not yet be fully known (see information here), we are aware that there may be many of our peers and mentees who have previously and/or continue to experience harassment and discrimination in their workplaces. Recent news stories are likely to renew their pain.

NAASC is committed to creating safe conferences, and to working within our community to eliminate behaviors which are harmful to the targets, undermine the integrity of the scientific enterprise, and rob us of precious potential contributions by the survivors of abuse.

NAASC Activities

  • Key Focus Areas include:

include increasing participation by, and representation of, women, members of under-represented racial and ethnic groups in STEM, early-career researchers, and additional identities that span the full diversity of the human experience and our plant biology communities.


  • Specific areas we monitor for our activities have, so far, included: % female and/or early career stage invited speakers to ICARs.

  • Newer efforts will collect data on racial & ethnic identities and gender pronouns to enable us to gauge participation and effects of specific efforts on increasing representation and comfort level/"belongingness" of additional members of our community that have often been less/in-visible, and/or minoritized or excluded.

  • DiversifyPlantSci

    • NAASC is committed to promoting a global plant sciences community that reflects the true diversity of all its members.
    • To further this mission, members of the NAASC Diversity and Inclusion Task Force have created the DiversifyPlantSci online resource, a list of plant scientists from under-represented groups (see below) to reference as you seek speakers, reviewers, and participants for career or mentorship opportunities.
    • This list (and database) is intended to highlight the diversity within the global plant science community.
    • We hope to increase diversity and inclusion by making it easy to expand invitations past one’s personal networks.

How to Join and Use DiversifyPlantSci:

    • Nominate yourself if you are a plant scientist who: identifies as a woman; identifies as LGBTQIA+; has a disability; and/or is a member of an under-represented ethnic or racial group (As defined by the US National Science Foundation: Women, persons with disabilities, and three racial and ethnic groups—blacks, Hispanics, and American Indians or Alaska Natives—are underrepresented in US STEM; we also include Filipino. https://www.nsf.gov/statistics/2017/nsf17310/digest/introduction/)
      • You may also self-nominate if you otherwise belong to an underrepresented or minoritized group in academia (by your definition).
      • You may include in the database and entry form any other unlisted identities that you wish to, that represent the unique you.
    • Please do not nominate others, we allow self-registration only.
    • However we strongly encourage you to forward the form to others that you know and invite them to consider signing up for inclusion.
    • You may self-nominate by filling in the DiversifyPlantSci Self-Nomination Form
    • We've used some language from the DiversityEEB list, and here's their reference: https://diversifyeeb.com/entries/
    • Please do NOT use this database to "spam" many (or all) members as part of a broad or unfocused approach to reaching under-represented plant scientists. Use the list judiciously and keep in mind that a personal email is much more effective than a mass mailing. If you do send an email to more than one person, please use the 'bcc' option to reduce the likelihood of an annoying "reply-all" chain.
      • For broad announcements, please instead make use of the NAASC [@DiversifyPlants] (https://twitter.com/diversifyplants) Twitter account to *broadly* announce, for example, career positions, award opportunities, or seminar announcements that aren't aimed at individuals you have *individually* identified as highly relevant to your activity. The intent of this database is to help enable "real" new connections and expand networks in meaningful ways. This will be accomplished being intentional and thoughtful about reaching out to folks on the list.

Project's Three Main Objectives:

    • Identify emerging technologies where using Arabidopsis as a model organism will provide fundamental discoveries and enable translational research in crop species
    • Enhance interdisciplinary training of scientists for academia and extra-academic careers
    • Increase diversity of Arabidopsis research scientists using targeted mechanisms

Major Project Activities

    • Annual Focus Groups in each of 4 years (primarily involving North American plant biologists and several international community members) on three main topics:
      • Computational training of biologists for academia and industry in the 21st Century
      • Genomic experimental biology techniques for academia and industry in the 21st Century
      • Interdisciplinary Training and Cross-training for 21st Century Careers
      • *Wrap Up, Evaluation and Assessment and Write-Shop*
    • Enabling Participation of US Scientists to attend ICAR (2015-2021):
      • US Early Career Researcher (ECR) travel awards
      • US Under-Represented Minority (URM) travel awards for historically under-represented groups in US science
    • Community activities at each ICAR (2015-2021):
      • Community workshops on each year's theme (matching the Focus Group)
      • Interactive programs for community workshops involving early career researchers
      • ICAR 2017 included an expanded list of activities involving research and training needs, aimed primarily at early-career researchers. These activities were made possible by the ART-21 RCN award from the NSF to NAASC, and through sponsorship and partnership with the Donald Danforth Plant Science Center (DDPSC) in St. Louis.
      • Expanded ICAR 2017 Activities That Took Place in St. Louis, Missouri

ICAR 2017 Pre-Meeting Hands On Workshops for early career scientists:

The workshop content focused on emerging bioinformatic and computational skills and emerging genomics technologies. Activities included an full day workshops: Data Carpentry; phenotyping hackathon, and ATAC-seq lab:

    • Data Carpentry: This event was an example-driven workshop on basic concepts, skills and tools for working more effectively with data. Short tutorials alternated with hands-on practical exercises, and participants were encouraged both to help one another, and to try applying what they have learned to their own research problems during and between sessions.
    • ATAC-seq hands-on workshop on mapping chromatin accessibility and TF footprints: Instructor: Professor Roger Deal (Emory University)- This workshop introduced attendees to the ATAC-seq process including isolation of nuclei, preparation of ATAC-seq libraries, and analysis of the resulting data to identify open chromatin regions and TF footprints. This lab workshop included both wet-lab and computational components.
    • Hackathon for high-throughput phenotyping: Designer: Cody Markelz (University of California, Davis). On-site Instructors: Malia Gehan and Noah Fahlgren (Donald Danforth Center). Many plant biologists are not formally trained to perform tasks needed to piece together their own image processing phenotyping pipeline. The hackathon focused on expanding on the introduction to genomics data and data management and analysis for genomics research provided in the Data Carpentry workshop.
      • New Sessions: Quantitative and Computational Biology; Emerging Genomics Technologies.
      • Special Community Workshops: URM career-development workshop abd ECR career-development workshop

  • Collaboration with ASPB on "Changing Climates and Cultures" (CCC)

The mission of Changing Cultures and Climates is to provide information that supports and promotes diversity, inclusivity, and equity in the international plant sciences community so that it grows to more accurately reflect that of our larger, global society.

At CCC, on Plantae supported by ASPB, you will find impactful literature about culture and gender matters; information about programs and initiatives that focus on increasing and sustaining diversity in plant science; and a safe space to learn more about one another and to discuss topics around diversity, equity, and inclusion that impact our community. 

NAASC collaborates on this initiative though invovement of several members as well as the NAASC section of the webpage:


  • DiversifyPlantPubs Logo

  • #DiversifyPlantPubs

NAASC #DiversifyPlantPubs is simple and straight-forward. The NAASC DiversifyPlantSci Twitter account [@DiversifyPlants] (https://twitter.com/diversifyplants) re-tweets scientific articles, including pre-prints, written by scientists who self-identify as plant science researchers with diverse identity(ies). 

    • If you are Black, Indigenous, Latin@x, any race or ethnicity where you identify as a person of color, a woman, LGBTQIA+, occupy a social space or have an identity that is under-represented, minoritized, or less/in-visible in plant sciences--and you are publishing in the plant sciences--just @ us.
    • Include the link to the paper and any pics or biographical information. We will quickly scan the paper to make sure the submitter is an author and that the paper is relevant to plant sciences, and then we will re-tweet. 
    • Please note that the author that self-describes as bringing diversity should submit (not their co-authors)
    • You can also submit papers to DiversifyPlantPubs by direct message to us @DiversifyPlantSci, or by emailing This email address is being protected from spambots. You need JavaScript enabled to view it.
  • We want to promote, lift up, and disseminate the research of plant scientists whose identities diversify our community. We don't want to wait for the plant science community to increase its diversity and representation to make these contributions more visible.

This DiversifyPlantSci DiversifyPlantPubs initiative is inspired by, and modeled after, the EEB Papers of Color initiative from our colleagues in Ecology, Evolution, & Behavior (EEB); check them out @ EEB_POC and https://github.com/jhpantel/EEB_POC/blob/master/EEB_POC.pdf

The events of the past week provide another searing reminder that we have a great deal of work to do before we realize a world where everyone has a full, healthy life and the opportunity to fulfill their potential. 

The deaths of George Floyd, Breonna Taylor, Tony McDade, Ahmaud Arbery, and David McAtee are only the most recent and most violent examples of what Black Americans experience every day. While it might seem to some that academia and the sciences provide a space of refuge, racism is prevalent within the academy, and it is hurting valued members of our community. We acknowledge that for many of us, including our mentees, it may not be possible–or even appropriate–to focus on science right now.

As a group elected to represent the community of Arabidopsis researchers in North America, we:

    • Express our anger, sadness, and disgust at current events, including the violent response to peaceful protesters by police and the inflammatory language of many in leadership roles. NAASC strongly rejects racism and discrimination in any form.
    • Reach out to our Black colleagues, trainees, and students to express support and solidarity and empathy. We stand with the Black community, and extend our love and concern to other communities that experience injustice. 
    • Will continue our efforts to raise up and center minoritized voices. This includes using DiversifyPlantSci (https://tinyurl.com/DiversifyPlantSci) as one of several resources for identifying potential speakers for seminars, meetings and candidates for leadership roles, and sponsoring focused activities to support, mentor, and promote the advancement of under-represented minorities.
    • Reiterate that anti-racism work is explicitly part of NAASC’s mission, and should be for all scientists. We reaffirm our commitment to doing the work needed to break down structural inequities. In this article, we provide some resources for those with privilege. We commit ourselves to providing more resources in the future. 

We call on our colleagues who are not themselves in marginalized communities to reflect on what specific actions you can take to support those in the Black community. In addition, we ask our entire NAASC constituency to provide feedback for how we might better serve and support you.

Members of the North American Arabidopsis research community are nominated and elected by the community to serve on the NAASC since 1992.

  • The history, structure (evolving) and membership of NAASC are described below:

During the first years of the Arabidopsis Genome Project, an ad hoc committee was formed to forge relationships and foster communication among the groups and countries world-wide who were involved in the genome sequencing effort. It was determined that the committee should be made up of three representatives from North America, two representatives each from continental Europe and the United Kingdom, and one representative each from Australia and Japan. These representatives would be elected by the groups that they would represent, and they would serve terms of three years. This committee was known as the Multinational Science Steering Committee. In February of 1992, in response to the need for elected North American representatives to the Multinational Science Steering Committee, Howard Goodman, Elliot Meyerowitz and Chris Somerville called for the formation of a North American Arabidopsis Steering Committee (NAASC). In the first election, six North American Arabidopsis researchers were elected.

In its first year, the NAASC dealt with a number of issues including the decision to have a National Arabidopsis meeting in Ohio in 1993, determining who should represent North America on the Multinational Science Steering Committee, and advising the NSF and other funding agencies of the community's needs for database services.

It was additionally determined that the committee would consist of six members and that members would serve for three years. Two new members would be elected annually via the Arabidopsis Newsgroup , and two members would retire.

Since that time, the NAASC has evolved into the main organizing and fundraising body for the International Conference on Arabidopsis Research when it is held in North America. The conference is now held annually and rotates between North America, Europe, and Austral-Asia.

The NAASC also collaborates with MASC members that volunteer to host the annual ICAR. NAASC solicits funds to help North American junior scientists travel to these international meetings. Since 2004, the NAASC has applied for funding to allow underrepresented minorities, and scientists from Historically Black Universities and Minority-Serving Institutions in the United States to fully participate in the Annual Arabidopsis meetings. Additionally, the NAASC serves as a liaison between members of the community and government and not-for-profit granting agencies and provides representation of the community to service facilities.

In 2000, the members of the NAASC unanimously voted to amend the process of election and alter the term of service for members to coincide with the annual conference rather than the calendar year. It was felt that this alteration would help to ensure continuity in the committee. In 2003, the process was again amended, in the following ways:

Each member of the committee will serve for four full years, to further aid in continuity in the committee (August 29, 2017 Update to NAASC Term of Service: To provide better continuity and shared knowledge for NAASC-organized ICARs the term of service increased from four to five years. All NAASC elections beginning with fall 2017 will designate 5 year terms for new NAASC members.)

Members of the North American Arabidopsis research community who have served previously on NAASC may be re-nominated for the election, and if elected, may serve another term on the committee.

  • NAASC Org Chart 22Nov2020



Description: The North American Arabidopsis Steering Committee (NAASC), an elected body, was founded in 1992 to provide North American representation to the Multinational Arabidopsis Steering Committee (MASC) and to forge relationships and foster communication among the groups and countries world-wide that are involved in research, education, and outreach using Arabidopsis. NAASC organizes and raises funds for North American International Conferences on Arabidopsis Research (ICAR), and supports North American researchers to participate in additional ICARs. NAASC provides leadership to develop, secure funding for, and implement community-serving projects and activities and enable opportunities to support the full diversity of the Arabidopsis community, particularly in North America. http://arabidopsisresearch.org/index.php/en/naasc

Membership: NAASC has 10 elected members with two new members elected annually by the North American Arabidopsis community; members serve a 5-year term. Eligibility to serve on NAASC: Persons at the postdoctoral scholar level and higher, residing and working on Arabidopsis-related research and/or education and/or training at a North American University or Institution. 


Description: The NAASC Diversity, Equity and Inclusion Leadership Committee was founded in 2020 to more effectively and inclusively coordinate efforts between NAASC and its subcommittees, and to expand community input and participation in areas of diversity, equity and inclusion of multiple identities of the Arabidopsis community. DEILC will ensure NAASC uses a lens of social and racial equity and inclusion during activity development and implementation; particular attention is paid to ensure that historically less-resourced racial and ethnic groups, and early career scholars, have representation in NAASC activities.  


Description: The NAASC Inclusivity Scholars Subcommittee (ISS) was founded in 2013 (as the Minority Affairs Committee, MAC) to increase the presence of historically under-represented ethnic and racial groups in the fields of Arabidopsis research, education, and outreach, as well as to collaboratively address issues they face as plant scientists and in society. ISS seeks to coordinate activities related to promoting diversity in plant sciences, primarily through cultivating programs and communities around the ICAR Inclusivity Scholars Program (ISP, formerly the Under Represented Minority (URM) Travel Award Program). ISS will continue to provide resources, opportunities, mentoring and training to current and past members of this ISS cohort.

Membership: ISS is co-chaired by two members of the Arabidopsis community, currently these are Siobhan Brady (UC Davis) and Terri Long (NCSU) whose primary focus is coordinating and enabling the ISP and associated cohort. Past ICAR awardees (previously “URM cohort members”) are eligible to join ISS; additional interested North American Arabidopsis scientists or educators whose experiences and background are relevant can also apply to join ISS. ISS welcomes allies to participate in ISS activities, and especially promotes action by allies to challenge power structures in their own institutions and groups that seek to oppress or disenfranchise historically under-represented ethnic and racial groups. Members will be asked to provide brief biosketches that focus on their interests in diversity, equity and inclusion (as well as research and educational interests). 

To Apply:  Email* these materials: (1) Statement on interests: up to 1 page describing your scientific, educational, and/or outreach interests that are relevant to Arabidopsis and/or other plant sciences and why you wish to serve on the ISS including your interest, activities, and/or priorities for increasing the presence of under-represented ethnic and racial groups in plant sciences. Please indicate whether you are yourself Black, African American, LatinX, or Indigenous; or alternatively, if you consider yourself an ally from a non-minority/represented group.

Description: The NAASC Early Career Scholars Subcommittee (ECSS) was founded in 2020 to 1) ensure that Early Career Scholars (ECS) have representation in NAASC activities at all stages of activity development and implementation, and 2) to provide a forum where we can collaboratively address issues specific to ECS. ECSS liaises with NAASC via DEILC.

Membership: ECSS will be co-chaired by two North American Arabidopsis community members, one of whom should be an elected member of NAASC, and that themselves are ECS, defined as: undergraduate or graduate students, postdoctoral scholars, junior faculty (pre-tenure), or others (e.g., research scientists and faculty in non-tenure track positions). All ECS are defined as within 10 years of securing a doctorate in a relevant field or 15 years of securing a master’s degree (if that is their terminal degree). Co-chair terms: (1) elected NAASC member: equal to their term on NAASC unless they are replaced prior to end of their term. (2) If not an elected NAASC member: two years, eligible for renewal upon NAASC approval. Eligible to join ECSS: past North American-based NAASC early career travel awardees and any interested North American Arabidopsis scientists or educators whose experiences and background are relevant to ECSS. Applicants/Members will be asked to provide brief biosketches that focus on their interests in diversity, equity and inclusion (as well as research and educational interests). 

To apply: Email these materials: (1) Statement on interests: up to 1 page describing your scientific, educational, and/or outreach interests that are relevant to Arabidopsis or other plant sciences and why you wish to serve on the ECSS.
