Elucidation of the phylogeny of Cucurbitaceae, particularly Trichosanthes, based on plastome data and nuclear single-copy genes.

ABSTRACT:

Background

Cucurbitaceae is an economically important family with a wide geographical distribution range. The phylogenetic backbone of Cucurbitaceae has not been well resolved, and conflicting results have been reported in previous phylogenetic studies. Trichosanthes is the largest genus in Cucurbitaceae; however, its infrageneric classification remains controversial. Here, we used both plastome and nuclear datasets to reconstruct the phylogeny of Cucurbitaceae with emphasis on Trichosanthes. The plastome dataset includes 137 taxa, representing 15 tribes and 35 genera. The 1,244 single-copy nuclear genes (SCNs) dataset includes 143 samples from all 15 tribes and 68 genera of Cucurbitaceae.

Results

Phylograms of plastome dataset and 1,244 SCNs essentially agreed with each oth
