	Arabidopsis thaliana - Wikipedia, the free encyclopedia
		Arabidopsis thaliana, Thale Cress, or Mouse-ear Cress, a small flowering plant related to cabbage and mustard, is one of the model organisms for studying plant sciences, including genetics and plant development.
		Arabidopsis is not a plant with major agronomic significance, however, there are several advantages that resulted in it becoming a model organism for understanding the genetic, cellular and molecular biology of flowering plants.
		While gravitropic response of Arabidopsis root organs is the predominant tropic effect in these organs, specimens treated with mutagens and then selected for the absence of gravitropic action have shown both negative phototropic response to blue or white light, and positive phototropic response to red light.

Arabidopsis thaliana, or Thale Cress, a small flowering plant related to cabbage and mustard, is one of the model organisms for studying plant sciences, including genetics and plant development.

Similarly as mouse and fruit fly (Drosophila) are used as model organisms to understand human biology, Arabidopsis thaliana is used to study agronomic crops.

Arabidopsis has been used extensively in the study of the genetic basis of phototropism, chloroplast alignment, and other light influenced processes.

		Although the efforts of Arabidopsis sequencers have perhaps been less heralded than those of their colleagues working on animal genomes, the results they have yielded are no less scientifically interesting.
		Arabidopsis may be a simple plant (its detractors call it a weed!) with only 50 identified cells types and no complex nervous system or behavioural response, but its genome is surprisingly complex.
		Arabidopsis was an obvious choice for the first plant genome project, but it will never feed the world.

	Multinational Coordinated Arabidopsis thaliana Genome Research Project
		Arabidopsis thaliana, a small plant in the mustard family, was chosen for this large-scale research effort because it offers many advantages for detailed genetic and molecular studies.
		Because Arabidopsis is one of the most intensively studied organisms, and is a direct model for 250,000 closely related species, we believe that it is appropriate to undertake a major investment in developing new information retrieval tools (IRTs) for Arabidopsis in particular and plants in general.
		The focus of research with Arabidopsis is likely to change in the future from the immediate emphasis on mapping, sequencing, and gene identification, to the long-term questions of general biology and gene function during plant growth and development.

	Arabidopsis - Wikipedia, the free encyclopedia
		This genus is of great interest since it contains Thale Cress (Arabidopsis thaliana), one of the model organisms used for studying plant biology.
		Their findings confirm that the species formerly lumped together as Arabidopsis were polyphyletic.
		All of the species in Arabidopsis are indigenous to Europe and two of the species have broad ranges extending into North America and Asia.

	Other Model Organisms
		Arabidopsis thaliana is a small flowering plant that belongs to the Brassica family, which includes species such as broccoli, cauliflower, cabbage, and radish.
		Because Arabidopsis has a small genome relative to other plants and is easily grown under laboratory conditions, it has become the organism of choice for basic studies of the molecular genetics of flowering plants.
		Scientists expect that systematic studies of Arabidopsis will offer important advantages for basic research in genetics and molecular biology and will illuminate numerous features of plant biology, including those of significant value to agriculture, energy, environment, and human health.

	Plant and Animal Genome V Arabidopsis Workshop
		Integrating the analytical data from the US and French Arabidopsis projects with the Japanese rice project and the USDA-IFG/North Carolina State University pine project has resulted in some tantalizing preliminary results on what may be specific to Arabidopsis, and, at the very least, allows commonalities across the evolutionary spectrum to be identified.
		To produce a `mutation machine' in Arabidopsis and recover inserts in any gene of interest, this linked transposition behaviour was utilized to produce plant populations saturated for independent transpositions in specific chromosomal regions.
		Plant populations, with an I element transposing on chromosome 4, were organized in pools and the extracted DNA used for PCR screening with primers derived from sequenced genes in chromosome 4.

		A custom EMS mutation of up to 1.5 grams of Arabidopsis seeds with grow-out of the M2 is $742 for the mutation service and $141 per M1 flat grow-out with a 12 flat minimum.
		After years of evaluation, we have determined that Arabidopsis is particularly well-adapted to this specific PMP peat moss which is very consistent because it comes from a Canadian producer who owns the peat farm.
		In-house, Arabidopsis grow-out testing has indicated that PMP performance is essentially equal to that of enriched AIS.

		Interestingly, in Arabidopsis this motif is associated with dark-induced genes and is over-represented in genes under circadian regulation [12].
		The potential participation of microsatellites in the control of gene expression is unclear, but according to recent studies in rice and Arabidopsis, their distribution may follow a gradient in the direction of transcription [18].
		Thus, the position of the TATA box in Arabidopsis is more similar to what is typically the case in animal promoters, usually 25–30 nt from the TSS [2] than what is found in yeast, where the TATA box has a variable position in the [-100, -40] region [30].
