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 ...
English: Confocal laser scanning fluorescence micrograph of thale cress anther (part of stamen). The picture shows among other things a nice red flowing collar-like structure (just below the anther) that makes it somehow similar to jellyfish.
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.

Arabidopsis thaliana ("thale cress") is a much-studied model for vernalization. Some ecotypes (varieties), called "winter annuals", have delayed flowering without vernalization; others ("summer annuals") do not. [12] [self-published source?] The genes that underlie this difference in plant physiology have been intensively studied. [9]
On the other side, some plants show adaptations to changes in soil salinity, in that the plant's exposure to salt initiates certain mechanisms for cell osmotic regulation and causes changes in this plant's water obtaining and loss behaviors. [1] One of such plants is the model plant Arabidopsis thaliana, a member of the family Brassicaceae.
The following three genes in Arabidopsis thaliana possess both common and independent functions in floral transition: FLOWERING LOCUS T (FT), LEAFY (LFY), SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1, also called AGAMOUS-LIKE20). [5] SOC1 is a MADS-box-type gene, which integrates responses to photoperiod, vernalization and gibberellins. [4]
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]
