タイトル Degradation of sphingoid long-chain base 1-phosphates (LCB-1Ps): functional characterization and expression of AtDPL1 encoding LCB-1P lyase involved in the dehydration stress response in Arabidopsis.
ジャーナル Plant Cell Physiol
Abstract Sphingoid long-chain base (LCB) 1-phosphates are degradated by LCB 1-phosphate lyase to C(16) fatty aldehydes and phosphoethanolamine. Here, we confirmed that the At1g27980 gene product, AtDPL1, is a functional LCB-1-phosphate lyase. Expression of green fluorescent protein fusion products in suspension-cultured Arabidopsis cells showed that AtDPL1 is located to the endoplasmic reticulum. The rates of fresh weight decreases of dpl1-1 and dpl1-2 mutants were significantly slower than those of the wild-type plants. This ability to limit their transpiration reflected the leaf temperature of the mutant plants more than that of wild-type plants, suggesting that AtDPL1 plays a role in dehydration stress.
