Abstract
The effects of the brassinosteroid hormone 24-epibrassinolide (EPB) on growth indices and tyrosine phosphorylation of soluble proteins in pea (Pisum sativum L.) leaves after salinity action were studied. Treatment of plants subjected to salinity (150 mM NaCl for 2 days) with 100 nM EPB for 2 h resulted in the resumed shoot growth. The analysis of phytohormone-induced changes in the tyrosine phosphoproteome after NaCl treatment showed that EPB suppressed tyrosine phosphorylation of proteins functioning in the dark stage of photosynthesis. This is evidently related to the recovery of photosynthetic activity and, as a consequence, of plant growth indices.
