植物营养元素胁迫相关microRNA研究进展

Advance on MicroRNA Involved in Nutrient Element Stress in Plant

营养元素以多种方式参与植物光合作用、呼吸作用、能量代谢和信号转导等生理和代谢过程,是植物生长发育、产量和品质的重要物质基础。MicroRNAs(miRNAs)是一类存在于真核生物体中的内源性非编码单链RNA,在植物适应营养元素胁迫过程中发挥着重要作用。综述了近年来miRNA参与调控磷、硫、氮、钾等营养元素胁迫的研究进展,并对今后miRNA在植物营养元素胁迫领域的研究作出了展望,以期为利用miRNA进行营养元素高效利用分子育种提供新的思路。

Nutrient elements participate in various physiological and metabolic processes of plants in different ways,such as photosynthesis,respiration,energy metabolism and signal transduction,and are important material basis for plant growing development,yield and quality.MicroRNAs(miRNAs)are a kind of endogenous(non-coding)single-stranded RNAs,which play important roles in response to nutrient element stress in plants.This paper summarized the research progress of miRNAs in regulating nutrient element stress,especially phosphorus,sulfur,nitrogen and potassium,and prospected the future research of miRNAs in this field of plant nutrient stress.It was hoped to provide new ideas for molecular breeding using miRNAs for efficient use of nutrient elements.
