Abstract Environmental inputs such as stress can modulate plant cell metabolism, but the detailed mechanism remains unclear. We report here that FERONIA ( FER ), a plasma membrane receptor‐like kinase, may negatively regulate S ‐adenosylmethionine SAM ) synthesis by interacting with two synthases 1 and 2). participates in ethylene, nicotianamine polyamine biosynthetic pathways provides methyl group for protein DNA methylation reactions. The A rabidopsis fer mutants contained higher level of ethylene tissues displayed dwarf phenotype. Such phenotype was mimicked over‐expressing synthetase transgenic plants, whereas sam1/2 double mutant showed an opposite propose receptor response to environmental hormones auxin BR , interacts down‐regulates biosynthesis.
