Bin Xu currently serves as an Associate Professor in Nanjing Agricultural University. His research interests are in the bioenergy and forage crop molecular breeding and biotechnology mainly through reverse genetic tools. Translating knowledge gained in model plant species to economically-important crops is an important route for improving crop agronomic traits. For example, low lignin content in the plant biomass was positively associated with higher biofuel production efficiency and higher forage quality. He have cloned and analyzed two Panicum vigatum lignin-synthesis Pv4CL genes using molecular, bioinformatical and biochemical tools. From the information he gathered, he predicated and then proved by generating and analyzing stable transgenic plants that Pv4CL1 was involved in lignin synthesis while Pv4CL2 not. Stay-green is a highly valuable phenotype for forage grasses for hay production. His lab identified and cloned several ryegrass genes involved in chlorophyll degradation. Through gene knock-down approaches, he obtained a series of stay-green ryegrass lines with different genes mutated. The long-term goal of his research aims to provide genetic information that is critical for bioenergy/forage crop improvement through molecular and conventional tools.
