    August 29, 2017 Update to NAASC Term of Service: To provide better continuity and shared knowledge for NAASC-organized ICARs, current NAASC agreed, by consensus, to increase the term from four to five years. Current members will opt-in to a 5th year, while all NAASC elections beginning with fall, 2017, will designate 5 year terms for new NAASC members.

    NAASC Activities

    RCN: Arabidopsis Research and Training for the 21st century (ART-21)

    You can view a brief overview of this activity as presented at PAG 2016 at:

    June 2015: NAASC member Siobhan Brady (as PI, UC Davis) and NAASC Coordinator (as co-PI, UC Davis), with contributions from several project Steering Committee members, were awarded 5 years of funding from the US National Science Foundation to support community engagement and activities focusing on research and training needs for Plant Biology in the 21st Century.

    Project's Three Main Objectives:

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

    Major Project Activities

    1. 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*
    2. Enabling Participation of US Scientists to attend ICAR (2015-2019):
      • US Early Career Researcher (ECR) travel awards
      • US Under-Represented Minority (URM) travel awards for historically under-represented groups in US science
    3. Community activities at each ICAR (2015-2019):
      • 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.
    4. Expanded ICAR 2017 Activities That Took Place in St. Louis, Missouri
      • Pre-Meeting Hands On Workshops for early career applicants. 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
        • ECR career-development workshop
    5. Publications/ Information Sharing
      • White Papers stemming from Focus Groups
      • Newsletters
      • Webpage information dissemination
      • Year 5 publication

    NAASC History

    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

    Elected NAASC Members

    Members of the North American Arabidopsis research community have been extremely generous in their willingness to serve on the NAASC. Since the initial call for an elected committee in 1992, 39 researchers have served on the committee.
