Defects in the cell wall and its depositions caused by loss-of-function of three RLKs alter root hydrotropism in Arabidopsis thaliana

lipids metabolism in the root tips were altered by the loss-function of three receptor-like kinases.
Relative amount of lipids in 5-mm root tips of wild-type (Col-0) and the triple mutant arh1-2 fei1-C fei2-C, (n=6), P<0.05. GL, glycerolipids; DG, diglyceride; TG, triglyeride; SL, saccharolipids; GP, glycerophospholipids; PC, phosphatidylcholine; LPC, lyso-phosphatidylcholine; MePC, methylphosphatidylcholine; PG, phosphatidylglycerol; PS, phosphatidylserine; PA, phosphatidic acid; PE, phosphatidylethanolamine; PEt, phosphatidylethanol; SP, sphingolipids; Cer, ceramides. Data are the means of six biological replicates.

三类受体类激酶（receptor-like kinases）的功能缺失会改变根尖的脂质代谢。本研究测定了野生型（Col-0）与三重突变体arh1-2 fei1-C fei2-C的5 mm根尖中的脂质相对含量（n=6，P<0.05）。其中各缩写对应的脂质类别如下：GL为甘油酯（glycerolipids），DG为甘油二酯（diglyceride），TG为甘油三酯（triglyeride），SL为糖脂（saccharolipids），GP为甘油磷脂（glycerophospholipids），PC为磷脂酰胆碱（phosphatidylcholine），LPC为溶血磷脂酰胆碱（lyso-phosphatidylcholine），MePC为甲基磷脂酰胆碱（methylphosphatidylcholine），PG为磷脂酰甘油（phosphatidylglycerol），PS为磷脂酰丝氨酸（phosphatidylserine），PA为磷脂酸（phosphatidic acid），PE为磷脂酰乙醇胺（phosphatidylethanolamine），PEt为磷脂酰乙醇（phosphatidylethanol），SP为鞘脂（sphingolipids），Cer为神经酰胺（ceramides）。数据为6次生物学重复的平均值。
