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).
