Plants have species-specific salt tolerance capacities. Induction of antioxidant defences, accumulation of osmolytes,
vacular localization of Na+ are the components of salt tolerance mechanisms. Structural adaptations like changes
in leaf size, stomatal opening/closure and modifications of leaf anatomy against salinity stress also play important role in
salt tolerance. Thetrichome metabolism related genes and their molecular mechanisms were identified in Arabidopsis. The
molecular mechanism of trichome formation in the epidermis is under control of
GLABROUS 1 (GL1), GLABROUS 3 (GL3)
TRANSPARENT TESTA GLABRA 1 (TTG1)
genes. The aim of this study is to determine theregulation of trichome-
metabolism-related genes against salt stress in soybean (
Glycine max L. Merr.
) plants. The 14-day-old Ataem-7 and S04-05
soybean seedlings were subjected to 0, 50, 100 and 150 mMNaCl stress. qRT-PCR analysis demonstrated an induction of the
soybean orthologs of
genes in soybean plants after 50, 100 and 150 mMNaCltreatments in both varieties. While
the expression level of
ortholog gene was negatively affected in both soybean varieties under different concentrations of
ortholog gene expression profile differed as a result of changing salt concentrations in both varietieswith respect
to control plants.
ortholog genes are also important for trichome formation for soybean. According to our
seems to be the main regulatory gene for initiation of trichome in two soybean varieties under salt stress.
