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 ...
A red light induced positive phototropism has been recently recorded in an experiment that used Arabidopsis to test where in the plant had the most effect on a positive phototropic response. The experimenters utilized an apparatus that allowed for root apex to be zero degrees so that gravitropism could not be a competing factor. When placed in ...
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 ...
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.
Lab-on-a-chip devices could be used to characterize pollen tube guidance in Arabidopsis thaliana. Specifically, plant on a chip is a miniaturized device in which pollen tissues and ovules could be incubated for plant sciences studies. [34]
George Rédei pioneered the use of A. thaliana for fundamental studies, mutagenizing plants with ethyl methanesulfonate (EMS) and then screening them for auxotrophic defects [5] and writing an influential review in 1975. [6] Rédei distributed the standard laboratory accessions 'Columbia-0' and 'Landsberg erecta'. [8] [18]
A wide variety of plants have been used to generate gnotobiotic systems such as Arabidopsis thaliana, peanuts, oats, corn, and many others. [17] Similar to animals, gnotobiotic plant systems have been used to study integral components of host physiology (e.g., nitrogen fixation ), [ 5 ] as well as pathogenic and symbiotic interactions between ...
CCA1 was first identified in Arabidopsis thaliana by Elaine M. Tobin’s lab in UCLA in 1993. [2] Tobin’s lab was studying promoter fragments that contribute to light regulation of light-harvesting Chlorophyll A/B Binding Protein (LHCB), and noticed DNA-binding activity that had affinity for a specific light-responsive fragment of the LHCB promoter.
