Overexpression of ARGOS Genes Modifies Plant Sensitivity to Ethylene, Leading to Improved Drought Tolerance in Both Arabidopsis and Maize.

abstract：:In comparison with other cell organelles, the Dunaliella salina plasma membrane was found to be highly enriched in phospholipase C activity toward exogenous [(3)H]phosphatidylinositol 4,5-bisphosphate (PIP(2)). Based on release of [(3)H]inositol phosphates, the plasma membrane exhibited a PIP(2)-phospholipase C activi...
