Fine Mapping of CsVYL, Conferring Virescent Leaf Through the Regulation of Chloroplast Development in Cucumber.

ABSTRACT: Leaf color mutants in higher plants are ideal materials for investigating the structure and function of photosynthetic system. In this study, we identified a cucumber vyl (virescent-yellow leaf) mutant in the mutant library, which exhibited reduced pigment contents and delayed chloroplast development process. F₂ and BC₁ populations were constructed from the cross between vyl mutant and cucumber inbred line 'Hazerd' to identify that the vyl trait is controlled by a simply recessive gene designated as CsVYL. The CsVYL gene was mapped to a 3.8 cM interval on chromosome 4 using these 80 F₂ individuals and BSA (bulked segregation analysis) approach. Fine genetic map was conducted with 1542 F₂ plants and narrowed down
