项目摘要
"In natural soils, nutrients are scarce and distributed heterogeneously. They support the life of a large number of organisms that inhabit the soil, including plants and microbiota, which have developed mechanisms to compete for nutrients and assimilate them efficiently. It is unknown whether the chemical compounds that are released during these competitions for different nutrients 'inform' plant roots about how to avoid extreme competition and find new patches of nutrients. With this project we will study how the complex chemical landscape existing in the soil, with special interest in compounds derived from bacteria, influences the decision-making process in the root to explore nutrient patches in the soil and activate the nutritional response. This will allow us to add new regulatory components to endogenous root development and plant nutritional pathways and better understand how the plant senses nutrients in the soil. Importantly, we will (a) identify and characterize novel bacterial exometabolites with the ability to modulate plant response to low nutrient levels. (b) provide new evidence on how microbes help plants survive in soils (c) we will discover new and important mechanisms for the regulation of nutrient uptake in soils.A natural extension of this work would be to a) further validate these findings in other economically important plants b) test the effect of the described exometabolites and the described mechanisms in more relevant ecological contexts.
在天然土壤中,养分稀缺且分布不均。它们支持大量生活在土壤中的有机体的生命,包括植物和微生物群,它们已经形成了竞争营养并有效同化它们的机制。目前尚不清楚,在这些争夺不同营养的竞争中释放的化合物是否会告诉植物如何避免极端竞争,找到新的营养补丁。在这个项目中,我们将研究土壤中存在的复杂化学景观,特别是来自细菌的化合物,如何影响根部的决策过程,以探索土壤中的营养斑块并激活营养反应。这将使我们能够在内源根发育和植物营养途径中添加新的调节成分,并更好地了解植物如何感知土壤中的养分。重要的是,我们将(A)鉴定和鉴定具有调节植物对低营养水平反应能力的新型细菌外代谢产物。(B)为微生物如何帮助植物在土壤中生存提供新的证据(C)我们将发现调节土壤中养分吸收的新的重要机制。这项工作的自然扩展将是a)在其他重要的经济植物中进一步验证这些发现,b)在更相关的生态环境中测试所述外代谢产物和所述机制的影响。
