Qian, Xu published the artcileAlcohol acyltransferase gene and ester precursors differentiate composition of volatile esters in three interspecific hybrids of Vitis labrusca × V. Vinifera during berry development period, Recommanded Product: Ethyl 3-hydroxybutanoate, the main research area is alc acyltransferase gene ester precursor Vitis hybrid berry development; Alcohol acyltransferase; Ester precursors; Esters; Grape varieties; Transcriptome analysis.
This study investigated the accumulation of esters in three hybrid grape cultivars during berry development under two vintages to elucidate the differentiation on their esters biosynthesis. Results showed ‘Moldova’ showed lower esters content than ‘Campbell Early’ and ‘Catawba’ resulting from its limited AAT gene expression and 20 different encoded amino acids. The volatile esters compositions of ‘Campbell Early’ and ‘Catawba’ in both vintages were different. Correlation anal. revealed that concentrations of hexyl acetate, 2-phenethyl acetate, Et (E,E)-2,4-hexadienoate and Et phenylacetate were related to their corresponding alcs. level, whereas threonine and alanine affected Et heptanoate formation. Transcriptome anal. indicated that 1847, 1781 and 1870 DEGs, at E-L 35, 36 and 38, resp., were characterized between ‘Campbell Early’ and ‘Catawba’. The expression level of genes related to the volatile ester precursors biosynthesis, including PRX-VIT_211s0016g05320, PAO-VIT_217s0000g09100, ACOX-VIT_212s0028g02660, ACOX-VIT_216s0022g01120, echA-VIT_205s0077g00860 and ACOX-VIT_200s0662g00010, exhibited a pos. correlation to the concentrations of their corresponding volatile esters.
