The GO enrichment analysis and expression pattern analysis of LcCCO genes by RNA-seq data. A The GO enrichment analysis of LcCCO genes in litchi. B The expression of LcCCO genes during peel coloring of ‘Feizixiao’ litchi treated by exogenous CPPU, CK: control group, T: CPPU treatment group. CK1 and T1: Green stage (the peel just completely wraps the pulp, 35d after anthesis), CK2 and T2: The best edible stage of fruit (57d after anthesis). C The expression of LcCCO genes of ‘Feizixiao’ litchi on the 0, 1, 3 and 7 days after bags removed. 0d: completely green; 1d, only the stipe was colored, 3d: The peel was half colored, 7d: fully colored. D The expression of LcCCO genes of ‘Nuomici’ Litchi during three different development stages of fruit. Green: the peel is completely green; Yellow: peel yellow; Red: peel red. E The expression of LcCCO genes of the entire inflorescences samples of ‘Feizixiao’ litchi on 28 days after the uniconazole treatment. CK: control group; T: treatment group. F The expression of LcCCO genes of fruit samples of ‘Wuye’ litchi after 2, 4 and 7 days treated by girdling plus defoliation. CK: control group, GPD: girdling plus defoliation. G The expression of LcCCO genes of abscission zone samples of ‘Feizixiao’ litchi after 0, 1, 2, 3 days treated by exogenous ethephon. CK: control group, ETH: exogenous ethephon treatment. H The expression of LcCCO genes of the peel samples on 0d and 4d after stored at room temperature and 0 h, 24 h and 48 h stored at room temperature after precooling for 14 days
