Genome-wide Analysis of WRKY Transcription Factors Family in Chickpea (Cicer arietinum L.)

Background: Chickpea (Cicer arietinum L.) is used as a protein source across the world. In plants WRKY transcription factors play an important role in regulation of stress resistance. An attempt was made to analyze WRKY genes in chickpea using genomic data. Methods: In this In Silico investigation during 2018-2019, to analyze the WRKY genes in chickpea using genomic data. iTak database are used to obtain gene data. Bioinformatics tools were used to analyzed the chickpea genomic data. Result: This study reported 61 Car WRKY genes, located on the seven main chromosomes of chickpea. Great variations were reported in terms of protein length, molecular weight, grand average of hydropathicity (GRAVY) value and theoretical isoelectric points of Car WRKYs. Gene Structure Display Server (GSDS) demonstrated that the Car WRKY 56 gene lack introns. Phylogenetic analysis of Car WRKY proteins divided in three main groups (I, II and III); group II was divided into three subgroups like Ila, IIb and IIc. By this an attempt has made to provide novel information on Car WRKY genes to study abiotic stress mechanism in chickpea.
