Title: The Innovations of Lizhong Xiong
Introduction
Lizhong Xiong is a prominent inventor based in Wuhan, China. He has made significant contributions to the field of agricultural biotechnology, particularly in the development of plant genetics. With a total of three patents to his name, Xiong's work focuses on enhancing plant root systems and improving tolerance to environmental stresses.
Latest Patents
One of Xiong's latest patents involves the MIR164 gene, which plays a crucial role in controlling plant root system development and fertility. This invention details a rice microRNA, miR164, obtained through gene isolation, cloning, and function verification. The patent describes the use of a nucleic acid fragment comprising miR164, which can increase root number and alter fertility in transformed plants. The nucleotide sequence containing the precursor of miR164 is ligated with an exogenous promoter and introduced into rice, resulting in transgenic rice plants with large root systems that may become infertile. However, fertility can be restored through the external application of phytohormones.
Another significant patent by Xiong relates to the transcription factor gene OsNACx from rice, which improves plant tolerance to drought and salt stress. This invention includes an isolated polynucleotide capable of conferring drought and/or salt tolerance to plants. It also encompasses a promoter that enhances this tolerance. The patent further describes an expression vector containing the polynucleotide and/or promoter, as well as a host cell transformed by this vector.
