520 |a Maleae is one of the most widespread tribes of Rosaceae and includes several important fruit crops and ornamental plants. We used nuclear genes from 62 transcriptomes/genomes, including 26 newly generated transcriptomes, to reconstruct a well-supported phylogeny and study the evolution of fruit and leaf morphology and the possible effect of whole genome duplication (WGD). Our phylogeny recovered 11 well-supported clades and supported the monophyly of most genera (except Malus, Sorbus, and Pourthiaea) with at least two sampled species. A WGD was located to the most recent common ancestor (MRCA) of Maleae and dated to c. 54 million years ago (Ma) near the Early Eocene Climatic Optimum, supporting Gillenieae (x = 9) being a parental lineage of Maleae (x = 17) and including duplicate regulatory genes related to the origin of the fleshy pome fruit. Whole genome duplication-derived paralogs that are retained in specific lineages but lost in others are predicted to function in development, metabolism, and other processes. An upshift of diversification and innovations of fruit and leaf morphologies occurred at the MRCA of the Malinae subtribe, coinciding with the Eocene-Oligocene transition (c. 34 Ma), following a lag from the time of the WGD event. Our results provide new insights into the Maleae phylogeny, its rapid diversification, and morphological and molecular evolution
