Arsenic is a toxic metalloid categorized under class 1 carcinogen and is detrimental to both plants and animals. Agricultural land in several countries is contaminated with arsenic, resulting in its accumulation in food grains. Increasing global food demand has made it essential to explore neglected lands like arsenic-contaminated lands for crop production. This has posed a severe threat to both food safety and security. Exploration of arsenic-resistant plant growth-promoting rhizobacteria (PGPR) is an environment-friendly approach that holds promise for both plant growth promotion and arsenic amelioration in food grains. However, their real-time performance is dependent upon several biotic and abiotic factors. Therefore, a detailed analysis of associated mechanisms and constraints becomes inevitable to explore the full potential of available arsenic-resistant PGPR germplasm. Authors in this review have highlighted the role and constraints of arsenic-resistant PGPR in reducing the arsenic toxicity in food crops, besides providing the details of arsenic transport in food grains.
砷是一种有毒的类金属，被归类为 1 类致癌物质，对植物和动物都有害。许多国家的农业用地受到砷的污染，导致其在粮食作物中积累。全球粮食需求的增加使得探索被忽视的土地，如受砷污染的土地，用于作物生产变得至关重要。这对食品安全和保障构成了严重威胁。探索砷抗性植物促生根瘤菌（PGPR）是一种环保的方法，有望促进植物生长和改善粮食中的砷含量。然而，它们的实时表现取决于许多生物和非生物因素。因此，为了充分挖掘可用的砷抗性 PGPR 种质资源的潜力，对相关机制和限制因素进行详细分析是必不可少的。本文作者强调了砷抗性 PGPR 在降低粮食作物砷毒性方面的作用和限制，同时还提供了粮食中砷迁移的详细信息。
