Fine Mapping and Functional Analysis of Major Regulatory Genes of Soluble Solids Content in Wax Gourd ().

Soluble solids content (SSC) is an important quality trait of wax gourd, but reports about its regulatory genes are scarce. In this study, the SSC regulatory gene in wax gourd was mined via quantitative trait locus (QTL) mapping based on high-density genetic mapping containing 12 linkage groups (LG) and bulked segregant analysis (BSA)-seq. QTL mapping and BSA-seq revealed for the first time that the SSC QTL (107.

Identification and Application of BhAPRR2 Controlling Peel Colour in Wax Gourd ().

Peel color is an important factor affecting commodity quality in vegetables; however, the genes controlling this trait remain unclear in wax gourd. Here, we used two F genetic segregation populations to explore the inheritance patterns and to clone the genes associated with green and white skin in wax gourd. The F and BC trait segregation ratios were 3:1 and 1:1, respectively, and the trait was controlled by nuclear genes.

Fine mapping and identification of the candidate gene BFS for fruit shape in wax gourd (Benincasa hispida).

Non-synonymous mutations in the BFS gene, which encodes the IQD protein, are responsible for the shape of wax gourd fruits. Fruit shape is an important agronomic trait in wax gourds. Therefore, in this study, we employed bulked segregant analysis (BSA) to identify a candidate gene for fruit shape in wax gourds within F populations derived by crossing GX-71 (long cylindrical fruit, fruit shape index = 4.
