This study aimed to introduce a stress-related gene to improve tolerance of one Egyptian wheat cultivar (Giza164) to oxidative stress, i.e., drought and salinity. This goal was achieved by introducing plant expression vector pLe-GST /bar harboring one of oxidative stress tolerance-related genes Le-GST into the genome using immature embryo-derived calli as a target tissue and microprojectile bombardment as a transformation device. However, the Le-GST gene was driving by CaMV 35S promoter and contained bar gene as a selectable marker. The plasmid pLe-GST/bar was constructed by ligating bar...

Abscisic acid (ABA) is a plant growth hormone that plays a key role in many physiological and developmental processes in plant cells. The present investigation examines differential gene expression in Vicia villosa under ABA treatment using differential display technique, in an attempt to identify stress genes whose expression is regulated by ABA and define their function. The results of the database sequence alignment identified 7 fragment sequences: At NADH dehydrogenase; Mt zinc finger CCHC type; Mt, Phaseolus vulgaris, Glycine max NBS-LRR plant resistance, Psychrobacter sp. arginine...
