Abstract:
Auxin has an important role in the various stages of plants growth and development. Studies have shown that auxin regulates these processes by auxin responsefactors (ARF) family. ARF proteins due to their central domain, mediate the cellular response to the auxin by activating or repressing the expression of downstream genes. ARF genes in several different plant species have been studied by molecular methods however to better understand the mechanisms of these proteins more studies are needed. In this study with computational methods, we found 27 ARF proteins, which they were scattered on the different parts of Phaseolus vulgaris chromosomes. The phylogenetic analysis of these sequences revealed they were divided into four different classes without any sign of gene-duplication between them. ARF genes expression according to the types of gene and based on the types of tissue respectively showed that they group into the five and two classes. In comparing with other tissues, ARF genes in leaf, young trifoliates, stems, mature pods and young pods tissues have a high level of expression. Of the 27 ARF Phaseolus vulgaris sequences surveyed in this study, nine ARF proteins were gene activator and 17 ARF proteins were gene suppressor.
