植物赖氨酸吸收与代谢调控及对植物的影响
Regulation of Lysine Uptake and Metabolism in Plants and Its Effects on Plants
摘要
Abstract
Lysine,a fundamental amino acid crucial for human and animal nutrition,also serves pivotal roles in amino acid homeostasis,growth,development,stress resilience and nutritional quality of plants.The biosynthesis,metabolic processes,absorption and translocation of lysine in plants directly or indirectly affect lysine content and its functions.While the metabolic pathways of lysine in plants have been relatively well characterized,the physiological and molecular mechanisms underlying its beneficial effects on plants remain largely unclear.In this paper,the recent advancements in understanding the roles and potential regulatory mechanisms of key genes involved in lysine uptake and metabolic pathways in plants were summarized,and the roles and possible regulatory mechanisms of key lysine absorption and metabolism genes in plant stress resistance,disease resistance,seed germination and improvement of crop quality were particularly elabrcted.Additionally,it reviewed the progress in breeding lysine-rich crops.Above results offered valuable insights and guidelines for elucidating the mechanisms regulating lysine transport and metabolism in cereal crops,thereby enhancing stress tolerance and fostering the development of novel lysine-enriched crop varieties.关键词
