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 basal leaves are green to slightly purplish in color, 1.5–5 cm long, and 2–10 mm broad, with an entire to coarsely serrated margin; the stem ...
Arabidopsis thaliana, currently the most popular model plant. This herbaceous dicot of the family Brassicaceae is closely related to the mustard plant. Its small stature and short generation time facilitates rapid genetic studies, [11] and many phenotypic and biochemical mutants have been mapped. [11] Arabidopsis was the first plant to have its ...
TILLING (Targeting Induced Local Lesions in Genomes) is a method in molecular biology that allows directed identification of mutations in a specific gene.TILLING was introduced in 2000, using the model plant Arabidopsis thaliana, and expanded on into other uses and methodologies by a small group of scientists including Luca Comai.
Pulse-chase analysis of auxin signal transduction in an Arabidopsis thaliana wildtype and an axr2-1 mutant. Wild-type and axr2-1 seedlings were labeled with 35S-methionine, and AXR2/axr2-1 protein was immunoprecipitated either immediately after the labeling period (t = 0) or following a 15-minute chase with unlabeled methionine (t = 15).
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.
Agroinfiltration is commonly used to transform tobacco . A common transformation protocol for Arabidopsis is the floral dip method: [23] An inflorescence is dipped in a suspension of Agrobacterium, and the bacterium transforms the germline cells that make the female gametes.
As a model organism, the Arabidopsis thaliana response to salinity is studied to aid understanding of other more economically important crops. High concentration of salt in the soil has negative effects on plants. For example, it reduces the yield that crop plants can produce in 7% of the land. [1]
The plant Arabidopsis thaliana is used in laboratories as a model organism to understand how genes control the growth and development of plant structures. [41] Space stations or space colonies may one day rely on plants for life support. [42]
