High impact information on PLDP1

• To characterize the changes in lipid species and to identify enzymes involved in plant response to phosphorus starvation, 140 molecular species of polar glycerolipids were quantitatively profiled in rosettes and roots of wild-type Arabidopsis (Arabidopsis thaliana) and phospholipase D knockout mutants pldzeta1, pldzeta2, and pldzeta1pldzeta2 [1].
• It was reported previously that inducible suppression or inducible overexpression of PLDzeta1 affected root hair patterning [2].
• With this system, the phospholipase Dzeta1 gene (AtPLDzeta1) was identified as a direct target of GL2 [3].

Associations of PLDP1 with chemical compounds

• Disruption of both PLDzeta1 and PLDzeta2 function resulted in a smaller decrease in phosphatidylcholine and a smaller increase in digalactosyldiacylglycerol in phosphorus-starved roots [1].
• The loss of PLDzeta2, but not PLDzeta1, led to a decreased accumulation of phosphatidic acid in roots under phosphate-limited conditions [2].
