Irregular green netting of eggplant fruit peel: a domestication trait controlled by SmGLK2 with potential for fruit colour diversification.

ABSTRACT: The distribution of chlorophylls in eggplant (Solanum melongena) peel exhibits either a uniform pattern or an irregular green netting pattern. The latter, manifested as a gradient of dark green netting that is intensified in the proximal part of the fruit on a pale green background, is common in wild relatives and some eggplant landraces. Despite the selection of uniform chlorophylls during domestication, the netting pattern contributes to a greater diversity of fruit colours. Here, we used over 2300 individuals from different populations, including a multi-parent advanced generation inter-cross population for candidate genomic region identification, an F2 population for bulked segregant analysis by sequencing, and advanced backcrosses for edges-to-core fine-mapping, to identify SmGLK2 gen
