Received: 25 March 2016 Returned for revision: 1 August 2016 Editorial decision: 3 November 2016 Published electronically: 10 January 2017 Background and Aims The breadfruit genus (Artocarpus, Moraceae) includes valuable underutilized fruit tree crops with a centre of diversity in Southeast Asia. It belongs to the monophyletic tribe Artocarpeae, whose only other members include two small neotropical genera. This study aimed to reconstruct the phylogeny, estimate diver- gence dates and infer ancestral ranges of Artocarpeae, especially Artocarpus, to better understand spatial and tem- poral evolutionary relationships and dispersal patterns in a geologically complex region. Methods To investigate the phylogeny and biogeography of Artocarpeae, this study used Bayesian and maximum likelihood approaches to analyze DNA sequences from six plastid and two nuclear regions from 75% of Artocarpus species, both neotropical Artocarpeae genera, and members of all other Moraceae tribes.
