Abstract:
CONCLUSIONS: Serendipita indica induced metabolic reprogramming in colonized plants complements phosphorus-management in improving their tolerance to arsenic stress on multifaceted biological fronts. Restoration of the anthropic damage done to our environment is inextricably linked to devising strategies that are not only economically sound but are self-renewing and ecologically conscious. The dilemma of heavy metal (HM) dietary ingestion, especially arsenic (As), faced by humans and animals alike, necessitates the exploitation of such technologies and the cultivation of healthy and abundant crops. The remarkable symbiotic alliance between plants and \'mycorrhizas\' has evolved across eons, benefiting growth/yield aspects as well as imparting abiotic/biotic stress tolerance. The intricate interdependence of Serendipita indica (S. indica) and rice plant reportedly reduce As accumulation, accentuating the interest of microbiologists, agriculturists, and ecotoxicological scientists apropos of the remediation mechanisms of As in the soil-AMF-rice system. Nutrient management, particularly of phosphorus (P), is also praised for mitigating As phytotoxicity by deterring the uptake of As molecules due to the rhizospheric cationic competition. Taking into consideration the reasonable prospects of success in minimizing As acquisition by rice plants, this review focuses on the physiological, metabolic, and transcriptional alterations underlying S. indica symbiosis, recuperation of As stress together with nutritional management of P by gathering case studies and presenting successful paradigms. Weaving together a volume of literature, we assess the chemical forms of As and related transport pathways, discuss As-P-rice interaction and the significance of fungi in As toxicity mitigation, predominantly the role of mycorrhiza, as well as survey of the multifaceted impacts of S. indica on plants. A potential strategy for simultaneous S. indica + P administration in paddy fields is proposed, followed by future research orientation to expand theoretic comprehension and encourage field-based implementation.
摘要:
结论:在定植植物中,Serendipita诱导的代谢重编程补充了磷管理,以提高其对砷胁迫的耐受性。恢复人类对环境的破坏与制定不仅在经济上合理,而且具有自我更新和生态意识的策略密不可分。重金属(HM)膳食摄入的困境,特别是砷(As),面对人类和动物,有必要开发这种技术并种植健康和丰富的作物。植物和“菌根”之间非凡的共生联盟已经进化了数千年,有利于生长/产量方面,并赋予非生物/生物胁迫耐受性。Serendipitaindica复杂的相互依存关系(S.印度)和水稻植物据报道减少了砷的积累,强调微生物学家的兴趣,农业学家,和生态毒理学科学家介绍了土壤-AMF-水稻系统中砷的修复机制。营养管理,特别是磷(P),还因通过阻止根际阳离子竞争而吸收As分子而减轻As的植物毒性而受到赞誉。考虑到水稻植物最大限度地减少As获取的合理成功前景,这篇综述集中在生理上,新陈代谢,和S.in共生潜在的转录改变,通过收集案例研究并提出成功的范例,恢复As压力与P的营养管理。编织一卷文学作品,我们评估了As的化学形式和相关的运输途径,讨论As-P-水稻的相互作用以及真菌在减轻As毒性中的意义,主要是菌根的作用,以及对S.in对植物的多方面影响的调查。提出了在稻田中同时施用S.in的潜在策略。其次是未来的研究方向,以扩大理论理解并鼓励基于领域的实施。
