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.
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.
English: Microbial consortia naturally formed on the roots of Arabidopsis thaliana Scanning electron microscopy pictures of root surfaces from natural A. thaliana populations showing the complex microbial networks formed on roots. a) Overview of an A. thaliana root (primary root) with numerous root hairs. b) Biofilm-forming bacteria.
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.
In order to escape shade, plants adjust their root architecture, most notably by decreasing the length and amount of lateral roots emerging from the primary root. Experimentation of mutant variants of Arabidopsis thaliana found that plants sense the Red to Far Red light ratio that enters the plant through photoreceptors known as phytochromes. [27]
The Arabidopsis Information Resource (TAIR) is a community resource and online model organism database of genetic and molecular biology data for the model plant Arabidopsis thaliana, commonly known as mouse-ear cress. [1]
