In silico analysis of transcriptional regulation of HMW glutenin genes in wheat
The storage proteins of wheat have a crucial role in the development of end-product quality; their allelic composition and expression determine the strength and extensibility of dough made from wheat flour.Prolamins consisting of monomeric gliadins and polymeric high molecular weight(HMW-GS) and low molecular weight glutenin subunits (LMW-GS), stabilized through inter-and intra molecular disulfide bonds, form a complex protein matrix, the gluten network.The composition and size of this network and its physico-chemical characteristics depend on the expression profile of the different components.An in silico analysis was carried out to identify various motif compositions in the promoter regions of HMW genes showing significant differences in gene expression.Our study was limited to HMW sequences and expressed sequence tags (EST) data available in public databases.Results show that no single motif is responsible for high or low expression but rather it is the composition of different motifs.
