Study on protein Changes in wheat under drought stress

Abstract

A study was performed to study the effect of drought stress on protein changes of five wheat genotypes. Wheat genotypes were planted in early November, growing season of 2008-2009. The experiment was carried out in a factotial design with three replications. Two drought stress levels (irrigated and Non irrigated) and five genotype of wheat (F103-L-1-12//PONY/OPATA, F1.158/FDL//BLO/3/SH14414/CROW/4/C ICWH99381-0AP-0AP-OMAR-6MAR, PYN/BAU//VORONA/HD2402, KATILA-13, and SARDARI- HD35/5/DMN//SUT/AG(ES86-7)/3/ICWH99-0552-0AP-0AP-OMAR-3MAR) factorialed in plots as random. Proteins profiling of samples was performed using SDS- polyacrylamide gels. The results showed that. In all genotypes the effects of drought stress on seed storage proteins were significant. Also results shows that, in drought stress treatment the seed storage proteins was more than irrigated treatment. No effects drought stress treatments on protein banding patterns. Also, results indicated that not obvious any new band and not deleted any bands. Therefore we concluded that seed protein bands are very stable in front of environment changes.
