Research and Interests

Arabidopsis genomics

Genome research using model systems has been adopted by plant and animal biologists to rapidly define genome architecture, gene function and aid the discovery of fundamental biology. Arabidopsis thaliana has become one of the most favoured model systems for the study of many aspects of plant metabolism, development and disease resistance.

Arabidopsis is a typical flowering plant but has special characteristics that recommend it as an ideal model for research. These include its small size, small genome size, prolific seed production and the diverse array of available mutations. The entire sequence of the genome for the Columbia ecotype of Arabidopsis was completed in December 2000. A second ecotype (Landsberg) was shotgun sequenced commercially at the same time and has provided a valuable comparison reference. Since that point, many different varieties (putative ecotypes) have been sequenced, making arabidopsis one of the best models for natural variation.

The principle behind using Arabidopsis is that information obtained from this model species can be applied to other flowering plants, including crops. Hence important problems faced by industry and agriculture can be addressed through translation of the knowledge base generated from Arabidopsis research.

Tackling genome research requires a scientific infrastructure to coordinate research and to centralise the provision of biological and information resources. NASC is involved in the provision of biological resources as the primary European Arabidopsis Seed Centre, and in the provision of information relating to our stocks and Arabidopsis genome information in general. NASC operates in parallel with the Arabidopsis Biological Resource Center (ABRC) at Ohio State, providing a safe repository for over half a million accessions and distributing this material to the scientific community. For details of the stocks we distribute, take a look at our NASC www server NASC currently distributes around 100,000 tubes of seed per year.

Please see our Wikipedia entry, our Twitter page (tweeting as @NascArabidopsis) and my OrcID profile.
