摘要:

类金属砷(As)是植物的非必要元素,其过量积累对植物有毒害作用,且经食物链危害人类健康。植物通过多个过程吸收与代谢砷,As5+形式的砷通过磷酸转运体吸收,而甲基化和As3+形式的砷主要通过水孔蛋白通道进入植物体。虽然曾提出过多种减轻植物砷毒害或减少其积累的对策,但它们在有效性以及环境友好等方面存在不足。本文较为系统地综述了As来源、吸收机理、砷磷互作及其对吸收、转运和植物生长和生理活性的影响,内容主要涉及植物在吸收、代谢和耐性上对砷胁迫和磷施加的反应。另外,本文还介绍了通过改善磷营养、操纵磷运转体基因以及优化植物-微生物群落而减少砷毒害和积累的最新进展。最后,简要讨论了今后面临的主要挑战和研究方向。

Abstract:

Metalloid arsenic (As) is not a necessary element for plants, but its excessive accumulation is toxic to plants, and it also poses a great health risk to humans via the food chain.  Plants absorb and metabolize As through a variety of processes.  Arsenate in the form of As5+ is absorbed by phosphate transporters, but methylated As and As3+ enter plant tissues mainly through aquaporin channels.  Various strategies and practices have been proposed and applied to alleviate As toxicity or reduce As accumulation in plants, but an efficient and environment-friendly approach has yet to be developed.  This review comprehensively explores As sources and uptake mechanisms, as well as the interactions of phosphorus (P) and As in their uptake, transportation and influences on plant growth and physiological activities.  This comprehensive review covers the transport, metabolism, and tolerance processes that plants exhibit in response to As stress and the addition of P.  In addition, we also present recent advances in reducing As toxicity and accumulation by improving P nutrition, manipulating P transporter genes and optimizing the plant microbial community.  Finally, the future research directions and main challenges are briefly discussed.
