| dc.description.abstract | Plasma membrane H+-ATPase, couples ATP hydrolysis to proton transport thereby establishing the driving force for solute transport into and out of plant cells. A sound depletion of H+-ATPase activity was noticed in diseased palms from that of healthy ones. The suppression of plasma membrane H+-ATPase in diseased palm was further substantiated by the impaired functioning of stomata and the disintegration of phloem and tracheary elements as observed under Scanning Electron Microscope (SEM). The results indicate the functional imbalance of electro chemical gradient created by H+-ATPase in the leaf cells. Moreover, the undifferentiated shrunken leaf tissues of diseased palms clearly clarify the loss of turgidity and cell wall plasticity due to suppression of H+-ATPase | en_US |
