Abstract

In an attempt to attain sustainability in agriculture, microbiome-based approaches have been investigated as “next-generation biologicals”. The top-down strategy of plant-mediated indirect selection of rhizospheric microbiome holds potential in generating a robust and efficient microbiome for enhancement of desired plant phenotype and its overall fitness. It involves multiple rounds of plant growth experiments under selection pressure such that the plant recruits a microbiome optimal for its fitness over the course of selection. In the review, we have critically discussed various aspects related to the approach, viz. methodological details, the current challenges faced by the technique, and the concerns related to the adoption of the plant-mediated indirect selection of microbiome at a larger scale. Besides, based on recent methodological developments and knowledge gained, we have proposed solutions for some of the issues, which will aid in popularizing the strategy.

摘要

为了实现农业的可持续性，基于微生物组的方法已被研究为“下一代生物制品”。植物介导的根际微生物组间接选择的自上而下策略在产生强大而有效的微生物组以增强所需植物表型及其整体适应性方面具有潜力。它涉及在选择压力下进行多轮植物生长实验，以便植物在选择过程中招募最适合其适应性的微生物组。在审查中，我们批判性地讨论了与该方法相关的各个方面，即。方法细节、该技术目前面临的挑战，以及与在更大范围内采用植物介导的微生物组间接选择相关的问题。除了，
