Sucrose increases calcium-dependent protein kinase and phosphatase activities in potato plants.
Year: 2003
Type: article
Abstract: The effect of sucrose on tuber formation, calcium-dependent protein kinase (CDPK) and phosphatase activities was analysed using in vitro cultured potato plants. In short treatments, sucrose induced CDPK and phosphatase activities. In long treatments, sucrose induced tuber formation in the absence of other tuber inducing stimuli. Sorbitol caused a minor increase in CDPK activity and affected plant morphology but did not induce tuber development. The addition of the protein kinase inhibitor Staurosporine precluded sucrose-induced tuberization. Altogether, our results suggest that phosphorylation/dephosphorylation events are involved in sucrose-induced tuber development.
