Abstract
The endogenous brassinosteroid (BS) profile was for the first time shown to change in response to salt stress in potato plants. A group of 6-keto-BSs was identified and found to significantly increase in content during salinization in contrast to other groups of hormones examined. A tenfold reduction in the level of endogenous BSs in mutant Arabidopsis thaliana plants with impaired biosynthesis (det2) (or reception (bri1)) of phytosteroids decreased their salt resistance, as evidenced by a lower efficiency of photochemical processes of photosystem II (PSII) and growth inhibition. The results confirmed the idea that endogenous BSs are involved in the formation of salt resistance in plants.
