“…S4), two antagonists of phosphoinositide-specific phospholipase C (PLC). PLC belongs to an important class of enzymes involved in hydrolyzing a membrane-associated phosphatidylinositol-4,5-bisphosphate (PIP2) to produce IP 3 and diacylglycerol [63]. The direct IP 3 stimulation of vacuolar Ca 2+ efflux (Fig.…”

“…Mammalian PI-PLCζ binds PI(4,5)P 2 via the XY linker [200]. The Ca 2+ binding by a C2 domain results in hydrophobicity changes, which is responsible for its membrane targeting [201]. The C2 domain alone of a rice PI-PLC is capable of targeting the enzyme to the membrane in response to Ca 2+ [201].…”

Phospholipases D (PLD) and C (PLC) hydrolyze the phosphodiesteric linkages of the head group of membrane phospholipids. PLDs and PLCs in plants occur in different forms: the calcium-dependent phospholipid binding domain-containing PLDs (C2-PLDs), the plekstrin homology and phox homology domain-containing PLDs (PX/PH-PLDs), phosphoinositide-specific PLC (PI-PLC), and non-specific PLC (NPC). They differ in structures, substrate selectivities, cofactor requirements, and/or reaction conditions. These enzymes and their reaction products, such as phosphatidic acid (PA), diacylglycerol (DAG), and inositol polyphosphates, play important, multifaceted roles in plant response to abiotic and biotic stresses. Here, we review biochemical properties, cellular effects, and physiological functions of PLDs and PLCs, particularly in the context of their roles in stress response along with advances made on the role of PA and DAG in cell signaling in plants. The mechanism of actions, including those common and distinguishable among different PLDs and PLCs, will also be discussed.

“…PLC members are implicated in membrane lipid hydrolysis function, various cellular processes, and signaling networks. Therefore, most researchers have focused on potential candidate exploration for their roles in stress tolerance and crop productivity (Abd‐El‐Haliem & Joosten, ; Rupwate & Rajasekharan, ). In our study, decreased hardness and increased electrical conductivity of banana fruits were observed when the banana fruit was treated with a banana anthracnose conidia suspension.…”

Phospholipase C (PLC) plays an important role in plant immunity, and anthracnose caused by the Colletotrichum species is a common postharvest disease of the banana fruit. This study aims to evaluate the role of PLC in anthrax resistance in banana. The experimental group of banana samples was treated with a banana anthracnose conidia suspension, and the control group was treated with distilled water. After inoculation, the groups were sprayed with ethephon, and indicators, such as hardness and conductivity changes; PLC activity, 1,2‐diacylglycerol (DAG) and phosphatidic acid (PA)content; and MaPLC‐1and MaPLC‐2 expression levels, were assessed at 0, 3, 6, 9, 12, and 15 days. Moreover, the expression levels of MaPLC‐1 and MaPLC‐2 were detected in various tissues. The hardness of banana fruits in the experimental group decreased faster than that in the control group. Furthermore, the conductivity was higher in the experimental group than in the control group. Regarding PLC activity, DAG, and PA content, bananas in the experimental group showed higher activities than those in the control group. Moreover, relatively higher expression of PLC mRNA was detected in anthracnose‐inoculated tissues. The evaluation of MaPLC‐1 and MaPLC‐2 expression levels showed that the mature peel had the highest MaPLC‐1 expression level. However, the MaPLC‐2 gene was expressed at relatively low levels in the fruit and at relatively high levels in the flower organs. PLC might play a role in fruit ripening in response to anthracnose resistance.
