Reticulate evolution is an important driving force of angiosperm
evolution. It has been proposed as an important evolutionary process in
Vitis subgenus Vitis. Events of natural hybridization and introgression of
several taxa native to North America have been hypothesized and discussed.
However, there is no convincing evidence of reticulate evolution reported
for closely related Vitis taxa from East Asia. We aim to explore natural
hybridization and introgression among four closely related Vitis taxa from
East Asia (V. amurensis, V. romanetii, V. shenxiensis, and V. piasezkii)
with the restriction-site associated DNA sequencing (RAD-seq) technique. A
total of 46 accessions, covering the potential morphological and
geographic variation of each species, are sequenced. Our results show a
complex evolutionary pattern of the four Vitis species. The phylogenetic
inference suggests that V. amurensis is monophyletic, however, V.
romanetii, V. shenxiensis, and V. piasezkii each do not appear to be
monophyletic. Significant signals of introgression in some accessions have
been detected by population structure analyses. D-statistics analysis and
population structure analyses support the presence of introgression
between V. shenxiensis/V. piasezkii and V. romanetii in sympatric
populations, but strong signal of admixture has not been recognized
between distantly located populations. Our results provide strong evidence
of reticulate evolution among V. romanetii, V. shenxiensis, and V.
piasezkii.
