Nutrient availability and efficient use are critical for crop productivity. Current agricultural practices rely on excessive chemical fertilizers, contributing to greenhouse gas emissions and environmental pollution. Rhizosphere microbes facilitate plant nutrient acquisition and contribute to nutrient use efficiency. Thus, engineering plant-microbe communication within the rhizosphere emerges as a promising and sustainable strategy to enhance agricultural productivity. Recent advances in plant engineering have enabled the development of plants capable of selectively enriching beneficial microbes through root exudates. At the same time, synthetic biology techniques have produced microbes capable of improving nutrient availability and uptake by plants. By engineering plant-microbe communication, researchers aim to harness beneficial soil microbes, thereby offering a targeted and efficient approach to optimizing plant nutrient use efficiency.
养分的可利用性和高效利用对作物生产力至关重要。当前的农业实践依赖于过量的化肥，这导致了温室气体排放和环境污染。根际微生物促进植物养分的获取，并有助于提高养分利用效率。因此，在根际中进行植物-微生物通讯的工程设计，是一种很有前景和可持续的提高农业生产力的策略。最近在植物工程方面的进展使人们能够开发出通过根系分泌物选择性富集有益微生物的植物。同时，合成生物学技术已经产生了能够改善植物养分可利用性和吸收的微生物。通过工程设计植物-微生物通讯，研究人员旨在利用有益的土壤微生物，从而提供一种针对植物养分利用效率的优化方法。
