Cuticular wax covers the surface of fleshy fruit and plays a protective role in fruit development and postharvest storage, including reducing fruit water loss, resisting biotic and abiotic stress and affecting fruit glossiness. The β-ketoacyl-CoA synthase (KCS) is the rate-limiting enzyme of very long chain fatty acids (VLCFAs) synthesis, which provides precursors for the synthesis of cuticular wax. In this study, a total of 96 KCS genes were identified in six Citrinae species, including 13, 16, 21, 14, 16 and 16 KCS genes in the primitive species (Atalantia buxifolia), the wild species (Citrus ichangensis), and four cultivated species (Citrus medica, Citrus grandis, Citrus sinensis and Citrus clementina), respectively.
