    With the support of the Beijing-Tianjin-Hebei project "Research on High-quality and Efficient Water-saving Technology for Fruits and Vegetables in Beijing-Tianjin-Hebei", the team of researchers Zuo Jinhua of the Institute of Vegetable Research of the Institute of Vegetables of Beijing Academy of Agriculture and Forestry Sciences and the team of Professor Christopher B.
    Watkins of Cornell University jointly participated in Postharvest Biology forbid Technology (Q1) in the journal of agricultural and forestry sciences IF:6.
    751) published a research paper entitled "Sugar accumulation forbid fruit quality of tomatoes under water deficit irrigation", which is based on the high sugar content tomato production model established by the team for many years, and is the first time in the world to use the method of multi-omics joint analysis to systematically study the formation of tomato fruits with a sugar content of more than 8%.
    The molecular mechanism of water deficiency irrigation technology regulating the flavor quality of tomato fruit is revealed, which provides a new theoretical basis
    for the improvement of fruit flavor quality.
     
    Tomato fruit is rich in nutrition, unique taste, deeply loved by the majority of consumers, with the improvement of people's living standards, consumers put forward higher requirements
    for vegetable product quality, flavor, nutrition and safety.
    China's vegetable industry is changing from quantitative to qualitative type, water deficiency irrigation technology not only saves water, but also improves the flavor quality of the fruit, this research in the independent research and development of the closed inorganic matrix limited root cultivation system (invention patent: ZL201510214349.
    X) on the basis of many years of research and establishment of deficit irrigation high sugar tomato production mode, the production of more than 8% of high sugar tomato.

     
    The research team systematically studied the regulation mechanism of tomato fruit flavor quality by combining high-throughput sequencing and bioinformatics by water deficit irrigation technology, resolved the differences in the expression profiles of mRNA and metabolites in the control group and the treatment group, and constructed a collaborative regulatory model
    for the change of tomato fruit flavor quality 。 The study found that the water deficit irrigation technology mainly improves the flavor quality of tomato fruit by regulating the expression of relevant genes and metabolites in purine metabolism, glyoxylic acid and dicarboxylic acid metabolism, galactose metabolism, starch and sucrose metabolism pathways, which provides new insights for the regulation and production of high-quality tomatoes, and provides a new basis
    for further studying the regulatory mechanism of the deterioration of flavor quality of high-quality tomato fruits.
     
    This achievement is an important scientific research progress made by the multidisciplinary team of the Beijing-Tianjin-Hebei project of the special project of scientific and technological innovation capacity building of our institute, Professor Liu Mingchi and Senior Agronomist Ji Yanhai are the co-corresponding authors of the paper, Zuo Jinhua researcher and doctoral student Bai Chunmei are the co-authors of the paper, Professor Christopher B.
    Watkins of Cornell University, Professor Wang Qing, Senior Engineer Liang Hao, and Dr.
    Zheng Yanyan participated in some of the work
