Résumé
Alcohol dehydrogenase (ADH) is essential to the formation of aromatic compounds in fruits. However, the evolutionary history and characteristics of ADH gene expression remain largely unclear in Rosaceae fruit species. In this study, 464 ADH genes were identified in eight Rosaceae fruit species, 68 of the genes were from pear and which were classified into four subgroups. Frequent single gene duplication events were found to have contributed to the formation of ADH gene clusters and the expansion of the ADH gene family in these eight Rosaceae species. Purifying selection was the major force in ADH gene evolution. The younger genes derived from tandem and proximal duplications had evolved faster than those derived from other types of duplication. RNA-Seq and qRT-PCR analysis revealed that the expression levels of three ADH genes were closely correlated with the content of aromatic compounds detected during fruit development.
