PLDZETA1 is an enzyme that hydrolyzes glycerol-phospholipids at the terminal phosphodiesteric bond, generating phosphatidic acids (PA). It exhibits a preference for phosphatidylcholine. PLDZETA1 plays a regulatory role in root-hair morphogenesis. It contributes to the supply of inorganic phosphorus for cell metabolism and diacylglycerol moieties for galactolipid synthesis in phosphorus-starved roots. PLDZETA1 is also involved in root elongation during phosphate limitation.

Under salt stress conditions, the efficiency of photosystem II, measured by the chlorophyll fluorescence ratio (F v/F m ratio), was significantly reduced in pldzeta1 mutants. This suggests that PLDzeta2 plays a crucial role in regulating Arabidopsis sensitivity to salt stress by fine-tuning ion transport and antioxidant responses. PMID: 28667438
