A gene encoding phospholipase D (PLD) in Saccharomyces cerevisiae was identified. The 195 kDa product of PLD1 has 24% overall sequence identity with a plant PLD. Expression of yeast PLD activity was eliminated by one-step gene disruption. Yeast haploids lacking PLD activity were deficient in growth on non-fermentable carbon sources. Diploids lacking expression of PLD1 were unable to sporulate.
