Arabidopsis: The Model Plant. Arabidopsis thaliana is a small dicotyledonous species, a member of the Brassicaceae or mustard family. Although closely related to such economically important crop plants as turnip, cabbage, broccoli, and canola, Arabidopsis is not an economically important plant A. thaliana is widely used in the fields of plant science, genetics and evolution and has helped further our understanding of germination and aspects of plant growth that are important in commercial crops. 1,2 In recent years A. thaliana has even become a model organism for the study of the biochemical and molecular processes involved in human.

The disadvantage of the Arabidopsis thaliana plant are that the genotypes resemble each other and they are hard to distinguish their phenotypes. The advantages are that they are easy to grow within a small proximity, devolop quickly in 6 to 8 weeks and has a variety of ecotypes The general disadvantages are: 1. Your model may not be truly representative of similar species. Example- Plant geneticists use Arabidopsis thaliana as a model, however as plants go Arabidopsis has..
. A consensus was reached about the need to focus on a single organism to integrate the classical disciplines of plant science with the expanding fields of genetics and molecular biology Arabidopsis thaliana (A. thaliana) is a popular model organism in plant biology (Van Norman and Benfey, 2009). A. thaliana was the first plant with sequenced genome (Arabidopsis-Genome-Initiative. advantage of a model system: an organism that is easily manipulated, genetically trac-table, and about which much is already known. By studying the biology of Arabidopsis, the model plant, we can gain comprehensive knowledge of a complete plant. In the laboratory, Arabidopsis offers the ability to test hypotheses quickly and efficiently Arabidopsis thaliana is an important model organism in plant biology with a broad geographic distribution including ecotypes from Africa, America, Asia, and Europe 1.. IntroductionFrom the mid 1980s, Arabidopsis thaliana (referred to herein as Arabidopsis) became an essential model plant for plant scientists due to the availability of various information and tools, such as whole genome sequence, molecular genetic markers and large collections of sequence-indexed DNA-insertion mutants, in addition to the ease of generating transgenic plants
Certainly Arabidopsis has some disadvantages as well. In particular, it does not produce fruit, and it is a dicot (while many of the world's food staples are monocots). So there are definite limits to the amount of information which can be extrapolated to fruit-bearing plants and the cereals Scientific Name: Arabidopsis thaliana. Organism Facts: Small, flowering plants related to cabbage and mustard. Prolific seed producers with an average life cycle of 6 weeks. Useful for studying factors that impact crop yields, such as drought stress and pest damage, because of their small size and short life cycle

Arabidopsis thaliana is an annual (rarely biennial) plant, usually growing to 20-25 cm tall. 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 leaves are smaller and unstalked, usually with an. Arabidopsis thaliana as model organism. Arabidopsis thaliana, the thale cress, mouse ear cress or arabidopsis is a small flowering plant. It is native to Eurasia and Africa. It grows in rocky, sandy and calcareous soil. Due to its widespread distribution on agricultural fields it's considered as weed. It grows luxuriously in temperate regions.

Dirigent proteins impart stereoselectivity on the phenoxy radical-coupling reaction, yielding optically active lignans from two molecules of coniferyl alcohol in the biosynthesis of lignans, flavonolignans, and alkaloids and thus plays a central role in plant secondary metabolism. Enantiocomplementary dirigent protein that mediates the laccase-catalyzed enantioselective oxidative phenol. Arabidopsis thaliana possesses certain characteristics that make it a suitable experimental plant model. Arabidopsis thaliana is a non-fastidious plant, it has a comparatively shorter generation time than other higher plants, it is able to reproduce by both self-fertilization and cross-pollination and produces abundant seeds which can range. Khana and Kutschera write that A. thaliana is an ideal model organism for some very basic reasons: it's small and easy to grow, it has a short generation time — the average time from the birth.
Arabidopsis thaliana • Small flowering plant native to Eurasia. • Considered a weed • Found by roadsides and in disturbed lands. • A winter annual with a relatively short life cycle, • Popular model organism in plant biology and genetics. • Relatively small genome of approximately 125 megabase pairs (Mbp) Arabidopsis thaliana is a widely used model for develop-mental and molecular plant biology.17 Availability of a collec-tion of indexed/characterized mutants and sequenced genomes of different Arabidopsis accessions promoted the generation of a large body of knowledge on the molecular mechanisms governing growth, development and stress responses In 1996, when the research plant community decided to determine the genome sequence of the flowering plant Arabidopsis thaliana, few people suspected that this model plant organism is an ancient polyploid.Nevertheless, even before the completion of the genome sequence, it was clear that a large portion of its genome consists of duplicated segments () Arabidopsis thaliana (Mouse-ear cress) Status.
