|a Barley (Hordeum vulgare) is one of the most important cereals in many developing countries where drought stress considerably diminishes agricultural production. Glutathione S-transferases (GSTs EC 2.5.1.18) are multifunctional enzymes which play a crucial role in cellular detoxification and oxidative stress tolerance. In this study, 84 GST genes were identified in barley by a comprehensive in silico approach. Sequence alignment and phylogenetic analysis grouped these HvGST proteins in eight classes. The largest numbers of the HvGST genes (50) were included in the Tau class followed by 21 genes in Phi, five in Zeta, two in DHAR, two in EF1G, two in Lambda, and one each in TCHQD and Theta classes. Phylogenetic analysis of the putative GSTs from Arabidopsis, rice, and barley indicated that major functional diversification within the GST family predated the monocot/dicot divergence. However, intra-specious duplication seems to be common. Expression patterns of five GST genes from Phi and Tau classes were investigated in three barley genotypes (Yusof [drought-tolerant], Moroc9-75 [drought-sensitive], and HS1 [wild ecotype]) under control and drought-stressed conditions, during the vegetative stage. All investigated genes were up-regulated significantly under drought stress and/or showed a higher level of transcripts in the tolerant cultivar. Additionally, GST enzyme activity was superior in Yusof and induced in the extreme-drought-treated leaves, while it was not changed in Moroc9-75 under drought conditions. Moreover, the lowest and highest levels of lipid peroxidation were observed in the Yusof and Moroc9-75 cultivars, respectively. Based on the achieved results, detoxification and antioxidant activity of GSTs might be considered an important factor in the drought tolerance of barley genotypes for further investigations
