Analysis MYB26 gene and male sterile and Anther dehiesence - Literature review ExampleThe Arabidopsis plant recruit flowers from April to early June. The plants of this family are known as crucifers due to their uniform flower structure that resembles a cross and are also characterized by a return named silique which is 5-20mm long with 20-30 spills. The leaves are alternate (rarely opposite) and sometimes organized in basal rosettes. Figure 1.

Heynh. 2n=10 is the most studied as the model plant. farming Plantae Order Brassicales Family Bras sicaceae Genus Arabidopsis Species Arabidopsis thaliana (L.) Heynh. Importance of A. thaliana as a model plant Though it has no significant economic value, A. thaliana is astray used as a model plant in studying a wide range of subjects in plant comprehension. This was first proposed as a model plant by Friedrich Laibact in 1943 (Meyerowitz, 2001) and now it is used extensively in studies based on evolution, communicables, population genetics and plant development. It is widely employ in genetic transformation studies, chromosomal analysis, genetic mapping and genome sequencing work. One important trait that makes A. thaliana an ideal model plant in plant science research is its small genome size. It has only five chromosomes with 157 million base pairs (Bennet et al., 2003) and the genetic and physical maps of all five genes are available. This is useful for genetic sequencing and mapping. In event the first plant genomes sequenced were of A. thaliana in the year 2000 where 11 5.4 mega bases of the 125mb genome were sequenced (Analysis of the genome sequence of the flowering plant Arabidopsis thaliana, 2000). Such information provides the basis of understanding molecular biological science of more plant traits and research has defined the functions of its 27,000 genes and the 35,000 proteins they encode (Integr8, 2011). In addition, A. thaliana has a short life cycle (six weeks from seed germination to seed maturation), has prolific seed production and the plant can be easily cultivated in restricted space. A. thaliana can be efficiently transformed with Agrobacterium and large list of mutants is available (www.arabidopsis.org). This plant has thus become valuable in genome projects and facilitates molecular level understanding of the biology of a flowering plant. Since Arabidopsis thaliana is similar to many other plants, it is believed that the properties found in Arabidopsis likely to be found in other flowering plants too. Therefore analyzing the s tructure and functions about Arabidopsis genes leave pave the pathway to study about other plant species. Arabidopsis Information Resources (TAIR), located in Carnegie Institute for Science Department of Plant Biology, the States maintain a genetic and molecular biology database of A. thaliana (www.arabidopsis.org). TAIR includes data on complete genome sequence with gene structure, gene product information, metabolism and gene expression, genome maps, genetic and physi
