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 ...
In Arabidopsis thaliana AP2 plays a role in the ABC model of flower development. [2] It was originally thought that this family of proteins was plant-specific; however, recent studies have shown that apicomplexans, including the causative agent of malaria, Plasmodium falciparum encode a related set of transcription factors, called the ApiAP2 ...
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 ...
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.
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 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.
The electron spin resonance study of Arabidopsis thaliana alternative oxidase AOX1a showed that the enzyme contains a hydroxo-bridged mixed-valent Fe(II)/Fe(III) binuclear iron center. [20] A catalytic cycle has been proposed that involves this di-iron center and at least one transient protein-derived free radical , which is probably formed on ...
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]
