Mission

The function of NAASC is to foster communication and relationships among North American Arabidopsis scholars and researchers, and act as liaison to international plant biology communities. Arabidopsis thaliana is a small flowering plant that is widely used worldwide as a model organism for basic research. A primary function of the organization is to organize and secure funding for (typically from government grants and sponsors) the annual International Conference on Arabidopsis Research (ICAR) when it is held in North America. ICAR promotes rapid exchange of information among students, postdoctoral scholars, faculty & other professional scientists. NAASC supports primarily US scientists to attend ICAR. NAASC also supports North American plant science activities involving research and education including by leading initiatives and collaborating on others. We secure government funding to develop community-serving activities to promote plant biology.

Program accomplishments

  • A primary function of the organization is to organize and secure funding for the annual International Conference on Arabidopsis Research (ICAR) when it is held in North America. The ICAR is currently on a 3 year rotation schedule so that it is held in North America once every 3 years. ICAR promotes rapid exchange of information among students, postdoctoral scholars, faculty & other professional scientists of the latest plant science information. The science conference also serves as an important forum for students & pre-professionals to highlight their research & education & take part in professional & educational development activities. The conference attendance is approximately 500 when in North America, and is open to the international community of people (including the public) that may wish to attend and learn and share plant biology research and education advances/information. As part of the ICAR, the organization provides funding to several invited speakers (particularly early career faculty that may lack significant funds.) The organization also provides significant support to students & postdoctoral scholars and others with reduced access, as part of its mission to promote plant biology and increase access within the scientific community. In 2025, ICAR was organized by international collaborators. Our organization provided travel funding for participation support of 13 US scientists, 12 of which were students, postdocs, and early career (non-tenured) faculty.
    grants $21,860
  • Another primary function of the organization is to support North American plant science activities involving research and education (often in cooperation and collaboration with international scientists). This support occurs in three major ways: Leading program and initiative development, including seeking governmental grants to fund projects; Participating in similar, related, and complementary activities to maintain and strengthen science ties; and (3) Providing advice or input when requested, from other groups and initiatives. Examples of how the organization carries out each of these: Organization members previously secured a governmental grant from National Science Foundation to lead plant science activities including workshops, meetings, outreach efforts, and develop publications and other scholarly reports, and communicate w/public. Members participate in workshops & other activities, including giving presentations, and/or co-authoring articles, with other groups. The organization collaborates & gives input to related educational & scientific groups and societies in cooperation & support of domestic and global plant science initiatives. In 2025, the organization developed several online webinars for our membership and led authorship of 2 publications in the primary plant biology journal, The Plant Cell: (1) A Timeline of Discovery and Innovation in Arabidopsis. https://doi.org/10.1093/plcell/koaf108. (2) In Defense of Funding Foundational Plant Science. https://doi.org/10.1093/plcell/koaf106. The organization also solicited community nominations for awards in these categories: (A) Arabidopsis Community Lifetime Achievement, (B) Arabidopsis Community Impact, and (C) Dissemination of Arabidopsis Knowledge. We awarded 3 awards in category (A), 3 awards, including 1 early-career award for category (B), and 4 awards, including 1 early-career award for category (C).
  • The organization serves as a liaison between members of the research community and government and not-for-profit granting agencies, and provides representation of the research community to service facilities such as the Arabidopsis Biological Resource Center (ABRC), which was established at Ohio State University in September 1991. The mission of ABRC is to acquire, preserve, and distribute seed and DNA resources that are useful to the Arabidopsis Research community. Additional groups that the organization has provided representation to includes: The Multinational Arabidopsis Steering Committee (MASC)- global plant scientist collaborations on Arabidopsis, the model plant. ROOT & SHOOT Initiative with the American Society of Plant Biologists (ASPB). In 2025, NAASC collaborated with ABRC to award a community member that donated the largest number of Arabidopsis stocks to ABRC. With MASC, NAASC participated in several meetings, including at ICAR 2025-Belgium in the 'Building solutions together: A community session on US research cuts to Arabidopsis and other science funding' meeting where the NAASC Executive Director presented 'NAASC PERSPECTIVES ON RESEARCH FUNDING IN THE US'. NAASC members also collaborated with MASC on developing an annual community research update report.
