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.
