Function
PLDα occupies a critical step in controlling stomatal movements and plant response to water stress.[1] PLDα is the common plant PLD that does not require phosphatidylinositol 4, 5-bisphosphate (PIP2) for activity, when assayed at millimolar concentrations of Ca2+.[2] PLDα1 promotes abscisic acid (ABA)-induced stomatal closure and regulates ABA-inhibited stomatal opening.[1][3][4] OsPLDα1 regulates salt tolerance in rice by activating H+-ATPase activity and transcription in tonoplast and plasma membrane. We also found that OsPLDα1 is important to transiently activate OsCDPK7 transcription in response to NaCl stress.[5] There are many PLDs in rice even OsPLDα can be consist of OsPLDα(1, 2, 3, 4, 5, 6, 7, 8 ), different genes own the same function or the partial overlapped function. Venn diagram for differentially expressed PLDs. PLD genes up- and down-regulated (A) under different abiotic stress conditions, (B) under stresses and developmental stages. Different compartments showing genes specific to either a particular stress/developmental stage or more than one stress and/or developmental stage.[6]

Evolution
Expression of rice PLD gene family has been represented by a heat map. Developmental stages comprising three vegetative stages (L-leaf, R-root and SL-7d-old seeding), six stages of panicle [P1 (0-3 cm), P2 (3-5 cm), P3 (5-10 cm), P4 (10-15 cm), P5 (15-22 cm) and P6 (22-30 cm)] and five stages of seed [S1(0-2 DAP), S2(3-4 DAP), S3(4-10 DAP), S4(11-20 DAP) and S5(21-29 DAP)]. Clustering of the expression profile was done with log transformed average values taking mature leaf as base line. Three stress conditions are denoted as C, Cold stress; D, Drought stress; S, Salt stress and SL, control, seven day old unstressed seedling.[6]
