Basic Research On Cotton Fiber Quality To Achieve National Breakthrough

A few days ago, from the national "973" seminar on "cotton fiber quality functional genomics research and molecular improvement project research seminar", we learned that the cotton fiber quality project team led by academician Yu Shuxun of the Cotton Research Institute of Chinese Academy of Agricultural Sciences has been working together for 10 consecutive years. Cotton fiber Development, quality formation and molecular improvement have made innovations and breakthroughs in theory, method and technology, greatly enhancing the international influence of cotton science and technology in China.

In view of the major demand and key scientific problems in the development of cotton industry in China, the Ministry of science and technology has been supporting the "2" program in 973 phases, namely, "cotton fiber quality functional genomics research and molecular improvement" and "cotton fiber quality functional genomics research and high-quality high yield new varieties molecular improvement" since 2004.

The project team has discovered ethylene can promote cotton. fibre In the first place, the ethylene centric cotton fiber elongation signaling pathway (COBP) was first identified, and the D genome mapping and sequencing of A genome were first completed in the world. A new method of cotton fiber proteomics research was established, and 235 differential display protein expression profiles closely related to fiber development were established. A large-scale transgenic technology system for cotton, a highly efficient functional verification platform for foreign gene and a cotton molecular polymerization breeding system were established. The high quality gene transferred from upland cotton to upland cotton was successfully obtained, and a batch of high-strength and high-quality fiber materials were obtained, and the first batch of new cotton varieties of high quality and high quality, including "cmiongsuo 70" and "Nongda cotton 13" and "Keza 6", were successfully produced in China. Cell elongation and ultra long chain fatty acids can regulate ethylene biosynthesis and release and regulate fiber development at transcriptional level, and the molecular mechanism of auxin promoting fibroblast initiation and enhancing lint yield.

A number of influential papers have been published in the world famous academic journals such as Nature Genetics, Nature Biotech and plant Cell (Plant Cell). Among them, there are 8 National Science and technology awards, 14 provincial and ministerial level awards, 1 National Natural Science two awards, two national technological invention awards, 1 two national science and technology progress awards, and 4 provincial science and technology progress awards. 2 scientists were elected academicians of the Chinese Academy of Sciences and academician of the Chinese Academy of engineering. Over the past 10 years, the project team has been

According to the introduction, with the development of national food security situation and agriculture industry With the adjustment of structure, China's future cotton industry will carry out a strategic shift of "moving eastward, westward and northward", and cultivate new varieties of high yield, high quality, disease and insect resistance, drought resistance and salt tolerance. The project team said that we should continue to consolidate key scientific issues based on the major needs of the state, thoroughly carry out basic and applied basic research work, continuously improve the original innovation capability, and comprehensively enhance the scientific and technological support capability of the cotton industry.
