Recently, the NEFU College of Life Sciences associate professor Lan Xingguo (Professor Li Yuhua research team), was published in one of the top journals of Molecular Plant Biology (Biology 1, IF = 8.8)in an article entitledFlavonoids and ROS Play Opposing Roles in Mediating Pollination in Ornamental Kale (Brassica oleracea var. Acephala).This research paper, shows that studies in the field of plant reproduction have made important progress.（http://www.cell.com/molecular-plant/fulltext/S1674-2052(17)30232-0）

Plant pollination refers to the male germ cell - pollen and pistil cells, the process of signal recognition and transmission, and ultimately through the fertilization of the seeds. This study on the mechanism of pollination is not only important in the field of plant reproduction, but also has a profound impact on the practical application of plant breeding strategies, which provide a theoretical basis for improving crop yield. According to the first author of the paper, Professor Lan Xingguo and associate professor Li Yuhua, stigma is the main part of pollination, while stigma growth and development of the regulatory mechanism must be consistent with its biological function. Therefore, a molecular strategy to analyze the function of stigma pollination is put forward by analyzing the molecular regulation mechanisms of stigma growth and development. The research team successfully used proteomics research methods to analyze the changes in the genes involved in the synthesis of reactive oxygen species (ROS) -related proteins and flavonoid compounds in the process of stigma development. For the first time, the ROS was analyzed including the role of the process and the role of flavonoid compounds in the process of non-affinity pollination. These studies provide important clues to the molecular regulation mechanisms of plant pollination and plant breeding strategies.
