| 1 | Cucumber glossy fruit 1 (CsGLF1) encodes the zinc finger protein 6 that regulates fruit glossiness by enhancing cuticular wax biosynthesis显示文摘Cucumber glossiness is an important visual quality trait that affects consumer choice.Accumulating evidence suggests that glossy trait is associated with cuticular wax accumulation.However,the molecular genetic mechanism controlling cucumber glossiness remains largely unknown.Here,we report the map-based cloning and functional characterization of CsGLF1,a locus that determines the glossy trait in cucumber.CsGLF1 encodes a homolog of the Cys_(2)His_(2)-like fold group(C2H2)-type zinc finger protein 6(ZFP6)and its deletion leads to glossier pericarp and decreased cuticular wax accumulation.Consistently,transcriptomic analysis demonstrated that a group of wax biosynthetic genes were downregulated when CsZFP6 was absent.Further,transient expression assay revealed that CsZFP6 acted as a transcription activator of cuticular wax biosynthetic genes.Taken together,our findings demonstrated a novel regulator of fruit glossiness,which will provide new insights into regulatory mechanism of fruit glossiness in cucumber. | Yan Yang Congxi Cai Yipeng Wang Yanran Wang Haolun Ju Xuehao Chen | 2023 | Horticulture Research2023，10，1： | 1 |
