Successful Cloning of Related Genes for Rice Phosphorus Utilization in Zhejiang University

Recently, Professor Wu Ping of the College of Life Science undertook the Ministry of Education's Expert Group Acceptance Meeting for the Major Project of Science and Technology Research of the Ministry of Education, “Cloning and Expression of Genes Relevant to High-Potass Phosphorus Utilization in Rice”. In the project study, the research team successfully cloned the first transcription factor OsPTF1 in the world that has a clear function of increasing phosphorus efficiency in plants. The acceptance expert group consists of 7 experts from Nanjing Agricultural University, Fudan University, China National Rice Research Institute and Zhejiang Academy of Agricultural Sciences. The team leader is chaired by Professor Xu Guohua. Acceptance experts agreed that the project has fully achieved its intended goals and has made breakthroughs in plant nutrition genome research. The research team cloned the OsPTF1 gene is the first in the world to report a transcription factor that has a clear increase in phosphorus efficiency in plants, has a good prospect of agricultural application, to improve crop phosphorus efficiency, reduce production costs, reduce the excessive use of Phosphate Fertilizer caused Environmental pollution is of great significance. Prof. Wu Ping’s group led a thorough study of metabolic regulation of rice under low-phosphorus stress conditions at the molecular level through the regulation of phosphorus stress-induced transcription factor expression, high-affinity phosphorus transporters, and hormone metabolism that controls root development. To adapt to the adaptation mechanism of low-phosphorus environment and to identify the allelic differences between different subtypes of rice and different genotypes in the main gene locus of phosphorus, OsPTF1 was successfully cloned through the implementation of this project. The research results have been published in the International Plant Physiology Journal of the American Plant Physiology, and won the national invention patent. The research group also cloned the OsPS1/2 gene of crop phosphorus signal, and studied its expression regulation mechanism. The cloning and application of OsIPS1/2 laid a foundation for further research on plant phosphorus signal transduction and regulation mechanism. The research results are published in the internationally renowned academic journal Plant, Cell and Environment.
