Expression of GSH gene related to heavy metals tolerance and accumulation in Brassica sp. plant genotypes

The present study included two experiments related to heavy metals tolerance and accumulation in Brassica sp plant genotypes Brassica juncea and Brassica nigra. The first one concerned with the study of two genotypes for Seedling characters. The second experiment was carried out under different molecular markersto characterize the relationship between treatment and over expression of GSH gene. The effect of treatment on the level of GSH hence, the highest expression as 5.3 fold of GSH was obtained in treatment with Cd, and 3.5 fold of GSH was obtained in treatment with Ni in B. juncea. While 1.4 fold was obtained in treatments Pb. The same results were obtained with treatment in B. nigra.
