Table 1 Total amount of lipid in each head group class in wheat leaves under OT optimal temperature and HT high temperature. Values are means ± standard error (SE; n = 10)

From: Decreased photosynthetic rate under high temperature in wheat is due to lipid desaturation, oxidation, acylation, and damage of organelles

MGDG monogalactosyldiacylglycerol, DGDG digalactosyldiacylgylcerol, PG phosphatidylglycerol, PC phosphatidylcholine, PE phosphatidylethanolamine, PI phosphatidylinositol, PA phosphatidic acid, PS phosphatidylserine, LPG lysophosphatidylglycerol, LPC lysophosphatidylcholine, LPE lysophosphatidylethanolamine. All polar lipid classes were represented as mean ± SEM, and the same lower case letter indicates no significant difference at LSD (α < 0.05) level between OT optimal temperature, and HT high temperature; different letters indicate a significant difference
