The world's first plant signaling molecule regulation technology ″COR-Coronatine″

In the past, due to the low output and high cost, the industrialization of COR faced great difficulties. Supported by the key R&D plans of ″China's National 863 Program″ (National High Technology Research and Development Program) and ″13th Five Year Plan″, Chengdu Newsun cooperated with China Agricultural University Plant Growth Regulators Engineering Research Center of the Ministry of Education, after nearly 20 years of scientific research, have constructed a high-yield engineering strain with a yield of 5-10 times higher than that of conventional strains, solved the problem of fermentation potency, and finally established the world's first production line of Coronatine fermentation in Chengdu Newsun, break through the bottleneck of production technology by using green and efficient microbial fermentation technology and biosynthesis technology. At the same time, membrane concentration, recrystallization and other methods are used to optimize the extraction and purification process of Coronatine, and finally obtain the Coronatine technical grade with a purity of more than 98%, realizing the batch production of Coronatine to meet the huge market demand.

As the world’s first industrialized jasmonate plant growth regulator, COR-Coronatine can be approved by ICAMA, which shows that China attaches great importance to the development and application of new, safe, efficient and economical biological pesticides. Through the in-depth and continuous research and transformation application of Coronatine in the fields of soybean seed treatment under low-temperature, abiotic stress resistance and yield increasing, fruit coloring improvement and sugar content increasing for citrus, grape, apple and other fruits, defoliation and weeding, it will certainly play an active and extensive role in improving global food security, agricultural products yield and quality in the future, and will also accelerate the green transformation of global agriculture, promote green agricultural production, and make great contributions to the green and high-quality development of global agriculture.
