Phospholipase D (PLD) and its product, phosphatidic acid (PA), play key roles in cellular processes, including stress and hormonal responses, vesicle trafficking, and cytoskeletal rearrangements. We isolated and functionally characterized Arabidopsis thaliana PLD{zeta}2, which is expressed in various tissues and enhanced by auxin. A PLD{zeta}2-defective mutant, pld{zeta}2, and transgenic plants deficient in PLD{zeta}2 were less sensitive to auxin, had reduced root gravitropism, and suppressed auxin-dependent hypocotyl elongation at 29°C, whereas transgenic seedlings overexpressing PLD{zeta}2 showed opposite phenotypes, suggesting that PLD{zeta}2 positively mediates auxin responses. Studies on the expression of auxin-responsive genes and observation of the ß-glucuronidase (GUS) expression in crosses between pld{zeta}2 and lines containing DR5-GUS indicated that PLD{zeta}2, or PA, stimulated auxin responses. Observations of the membrane-selective dye FM4-64 showed suppressed vesicle trafficking under PLD{zeta}2 deficiency or by treatment with 1-butanol, a PLD-specific inhibitor. By contrast, vesicle trafficking was enhanced by PA or PLD{zeta}2 overexpression. Analyses of crosses between pld{zeta}2 and lines containing PIN-FORMED2 (PIN2)–enhanced green fluorescent protein showed that PLD{zeta}2 deficiency had no effect on the localization of PIN2 but blocked the inhibition of brefeldin A on PIN2 cycling. These results suggest that PLD{zeta}2 and PA are required for the normal cycling of PIN2-containing vesicles as well as for function in auxin transport and distribution, and hence auxin responses.
