The Nottingham Arabidopsis Stock Centre (NASC) provides seed and information resources to the International Arabidopsis Genome Project and the wider research community. It is based in the School of Biosciences at the University of Nottingham 's Sutton Bonington Campus , in the English county of Nottinghamshire .
Arabidopsis (rockcress) is a genus in the family Brassicaceae.They are small flowering plants related to cabbage and mustard.This genus is of great interest since it contains thale cress (Arabidopsis thaliana), one of the model organisms used for studying plant biology and the first plant to have its entire genome sequenced.
Botanical illustration. Arabidopsis thaliana is an annual (rarely biennial) plant, usually growing to 20–25 cm tall. [6] The leaves form a rosette at the base of the plant, with a few leaves also on the flowering stem.

The protein PIN8 significantly influences the development of lateral roots in a plant. [7] When a nonfunctional mutant of the protein, pin8, was inserted into a plasmid, the lateral roots of Arabidopsis thaliana had a decrease in root density. [7] It was shown that this mutant had no lingering effects on the development of the primary root.
To do this, they took Arabidopsis plants, grew them in agar gel, and exposed the roots and shoots to separate sources of light. From here, they altered the different wavelengths of light the shoot and root of the plants were receiving and recorded the lateral root density, amount of lateral roots, and the general architecture of the lateral roots.
Arabidopsis thaliana is a first class model organism and the single most important species for fundamental research in plant molecular genetics. A. thaliana was the first plant for which a high-quality reference genome sequence was determined and a worldwide research community has developed many other genetic resources and tools.
Arabidopsis arenicola, the Arctic rock-cress, is a plant species native to the northeastern part of North America. It has been reported from Greenland, Labrador, Nunavut, Northwest Territories, Québec, Ontario, Manitoba, and Saskatchewan. It grows on sandy or gravely beaches or stream banks at elevations below 1,500 metres (4,900 ft).
