报告摘要：Plant roots associate with diverse microbes (bacteria, fungi, and viruses) collectively called the rhizosphere microbiome. Among them, mycorrhizal fungi and rhizobia colonize host roots and improve their access to nutrients, phosphorus and nitrogen. My research focus on the genetics, biochemistry, and cell biology of two symbiotic interactions of plants that can help to achieve higher crop yields with less usage of fertilizers: One is the arbuscular mycorrhizal association that helps the host plant to uptake nutrients from the soil and is especially important for plant acquisition of phosphate and nitrogen. The other is the rhizobial symbiosis that provides a source of nitrogen to the host plant. In addition, we propose to transfer our knowledge of the symbiosis into agronomical important food crops such as maize, wheat and rice to increase nutrient and water using efficiency, with the aim of boosting the food supply for future generations. Recently, the frameworks of nutrient exchange and regulation between host plant and arbuscular mycorrhizal fungi or rhizobia have recently been established. I will talk about our recent progresses on signal perception and nutrient exchange in plant-microbe symbioses.
