History and Purpose

The Multinational Arabidopsis Steering Committee (MASC) has its origin in the 1990s when scientists from the United States, Europe, Japan and Australia formed an ad hoc committee to promote large-scale studies in Arabidopsis thaliana. One of the main aims of the committee was and still is to strengthen international collaboration and coordination, to reduce redundancy and to help in guiding the community in making progress on projects that can be successful only by combined international efforts. This idea of a combined and coordinated effort accompanied by the policy of open data sharing has proven successful and led to the establishment of Arabidopsis thaliana as a reference plant and the Arabidopsis community as being one of the most active research communities. Arabidopsis researchers can look back on more than 40 successful  years – having published the first fully sequenced plant genome, functionally annotated most genes, and developed  a plethora of techniques, tools and resources. Within the previous 20 years two MASC road maps guided Arabidopsis research: ‘The Multinational Coordinated Arabidopsis thaliana – Genome Research Project’ in the 1990s and ‘The Multinational Coordinated Arabidopsis thaliana Functional Genomics Project’ in the 2000s. The third MASC road map was published in 2012 ‘The Multinational Arabidopsis Steering Committee – From bench to bountiful harvests’ (Lavagi et al., 2012, Plant Cell, 24:2240-2247). The main aim of the Arabidopsis community stated in the third road map is to obtain in-depth knowledge of how the genome is translated into a continuum of processes, from the single molecule to cells and tissues, the whole plant, plant populations, and fields of plants to be able to build a predictive model of an Arabidopsis plant, which is accompanied by the development of big data management systems. Additionally, Arabidopsis researchers have put increased effort into outreach to other plant communities and into translational approaches to allow effective exchange of information. 

Composition and Responsibilities

The Multinational Arabidopsis Steering Committee (MASC) is composed of representatives from each country with major efforts in Arabidopsis research or coalition of countries with smaller programs. It is open to any country interested in participating. Selection of MASC representatives is left to the discretion of each country. The MASC meets once a year in conjunction with the International Conference on Arabidopsis Research (ICAR). Rotating MASC chairs and co-chairs are selected from the MASC membership, including country representatives and subcommittee members. Specific responsibilities of the MASC are:

  • To coordinate programmatic aspects of the Arabidopsis research world-wide.
  • To facilitate open communication and free exchange of data, materials and ideas among the Arabidopsis research community.
  • To monitor and summarize progress of scientific activities of participating laboratories.
  • To identify needs and opportunities of the Arabidopsis research community and communicate them to funding agencies of participating nations.
  • To periodically update and adjust the course of the project
