植物钾离子通道和转运体及其对非生物胁迫响应研究进展
Research Progress on Plant Potassium Ion Channels and Transporters and Their Response to Abiotic Stress
摘要
Abstract
Potassium is a key nutrient required for plant growth and development,and its uptake and utilization are coordinated and complex regulatory processes.The available potassium in cultivated land is relatively low in our country,which often fails to meet the needs of crop growth.In addition,drought and salt stress seriously affect the absorption and utilization of potassium in crops,which leading to widespread potassium deficiency in crops.Plants have developed various mechanisms to cope with low potassium,salt,drought and other stresses in order to survive in various abiotic stress environments.This review systematically introduce the plant potassium channel family,types of potassium transporters,and the physiological and molecular mechanisms of potassium uptake,transport,and utilization in plant.This study focus on exploring the regulatory mechanisms of abiotic stresses such as salt and drought abiotic stresses on regulating the expression of potassium uptake and transport related genes in plants,and therefore the mechanisms of the potassium uptake and transport related genes on improving plant drought and salt tolerance.Finally,prospects were made on how to use cultivation,molecular biology,and molecular breeding techniques to improve potassium uptake and utilization,which provide theoretical basis for improving potassium fertilizer utilization efficiency and stress tolerance of crops.关键词
