Regulation of protein phosphorylation by nitric oxide in cell culture of Arabidopsis thaliana

Аннотация

Effect of nitric oxide (NO) on phosphorylation of soluble proteins in the cell culture of wild-type Arabidopsis thaliana (L.) Heynh. (ecoptype Columbia, Col-0) was studied. Among the identified proteins whose phosphorylation was affected by the NO donor treatment, the enzymes of primary metabolism (glyceraldehyde-3-phosphate dehydrogenase, enolase) and regulatory proteins (14-3-3-like protein GF14ω, protein-disulfide isomerase-like protein, chaperonin-60α) were detected. The results clarify possible mechanisms of NO action on primary metabolism, cell cycle, and stress-induced responses of cultured plant cells.
