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

ABSTRACT: 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 F₂ genetic segregation populations to explore the inheritance patterns and to clone the genes associated with green and white skin in wax gourd. The F₂ and BC₁ trait segregation ratios were 3:1 and 1:1, respectively, and the trait was controlled by nuclear genes. Bulked segregant analysis of both F₂ plants revealed peaks on Chr5 exceeding the confidence interval. Additionally, 6,244 F₂ plants were used to compress the candidate interval into a region of 179 Kb; one candidate gene, Bch05G003950 (BhAPRR2), encoding two-component response regulator-like protein
