  • 简介:砷(作为),由于自然以及人为的过程在土壤环境释放的潜在地有毒的非金属,被庄稼植物随后收起。在米饭谷物,作为在亚洲,北美洲和欧洲被报导了,建议未来威胁到食物安全和庄稼生产。作为凭它的可获得性,活动性和植物毒性的3+,是最有害的种类至于米饭庄稼。特定的transporters调停不同种类的运输作为从根到未葬植物身体的部分。累积作为在植物导致有毒的反应,影响它的生长和生产率。的增加当举起导致抗氧化剂的氧化应力和生产抵抗这,强调。对容忍的栽培变种因为应力在与敏感的相比的抗氧化剂新陈代谢是有效的。铁和硒被发现在引起由的氧化压力上有改善效果作为。微生物,甚至许多土生土长的,在植物,根围也能够作为在他们的新陈代谢利用,独立地并且在里面协会。一些这些微生物在在成年的植物给予忍耐到当压力是污染了地点。
