[Phytochrome regulation of the plant phospholipase activity].

The interaction of external stimuli with receptors of plant cell surface can activate the enzymes of lipid metabolism such as phospholipases C and D. The products of the catalysis, i.e., posphoinositide metabolites, phosphatidic acid, fatty acids, etc. participate in signal transduction as secondary messengers related to numerous regulatory processes. One of the physiologically important factors of regulatory control in plants is light, which plays the crucial role in triggering the cellular signaling network. This review presents the information on phospholipid signaling in plants, which is connected with light transduction processes occurring with the involvement of the plant regulatory pigment phytochrome.
