The regulatory network of sugar and organic acid in watermelon fruit is disclosed

A short while ago, the innovation undertaking watermelon and melon cultivation and physiology team of Zhengzhou Fruit Study Institute has created new progress in the metabolic process regulation of sugar and natural acid in watermelon fruit. The modifications of sugar and organic and natural acid through the fruit enhancement ended up analyzed and the critical gene networks controlling the metabolism of sugar and organic and natural acid throughout the fruit progress were discovered. These success offered a theoretical basis for watermelon excellent breeding, which had significant scientific importance for the growth of watermelon business and the enhancement of watermelon breeding degree in China. The connected analysis effects were released in the journals of Horticulture Investigation and Scientia Horticulturae.

The sensory top quality of watermelon fruit is decided by the written content of sugar and natural acid, which determines the style of watermelon throughout the development and maturation of watermelon fruit. The sweet watermelon ‘203Z’ and bitter watermelon ‘SrW’ of its isogenic line ended up utilised as supplies, the genes and gene networks co-expressed with glycolic acid metabolism ended up searched through WGCNA examination of transcriptional and metabolite details. Three gene expression networks had been determined, together with 2443 genes that were really correlated with sugar and organic and natural acid fat burning capacity in watermelon fruits. 7 crucial genes concerned in sugar and natural and organic acid metabolism of watermelon fruits were being screened by importance and qRT-PCR assessment. Amid them, Cla97C01G000640, Cla97C05G087120 and Cla97C01G018840 have been sugar transporters. Cla97C03G064990 was a sucrose synthase. Cla97C07G128420, Cla97C03G068240 and Cla97C01G008870 were being hugely correlated with malic acid and citric acid, which ended up the transporters and regulators of malic acid and citric acid. These genes have been confirmed in the normal population, and the benefits showed that the expressions of these 7 genes ended up appreciably positively correlated with the contents of sugar and natural and organic acid in watermelon fruit.
