摘要
稻田土壤重金属污染是引起环境和食品安全问题的主要原因之一。土壤中重金属的过量积累给水稻的生长发育、稻米产量和品质造成负面影响,并会导致重金属进入食物链。内生菌与宿主具有稳定的互利共生关系,一些有益内生菌能够提高水稻产量和重金属抗性。本文总结了抗重金属内生菌改善水稻重金属胁迫和减少植株重金属积累的机制,最后针对内生菌在农业中的研究与应用提出了几点展望。
Heavy metal pollution in paddy soils is one of main concerns causing some of the environmental and food safety problems.Excess accumulation of heavy metals in soil has a negative impact on the growth and development,yield and quality of rice,and will make heavy metals enter the food chain.Endophytes have a stable mutualism relationship with their hosts.It is well known that plant growth-promoting endophytes(PGPEs)enhance rice productivity and resistance to heavy metal stress.This paper summarized the mechanisms of heavy metal resistant-PGPEs in improving heavy metal stress and reducing the accumulation of these metals in rice.Finally,some prospects for research and application of endophytes in agriculture were put forward.
