Plastid capture history of subsect. Campylolepides and section Ilex(Fagaceae: Quercus)
Quercus subsect. Campylolepides contains three species: Q. acutissima, Q. variabilis and Q. chenii, which is the East Asian clade of Quercus section Cerris. Species formation and phylogeography of whole subsection or species within the subsection have been studied in detail. It has been also found t...

| description | Quercus subsect. Campylolepides contains three species: Q. acutissima, Q. variabilis and Q. chenii, which is the East Asian clade of Quercus section Cerris. Species formation and phylogeography of whole subsection or species within the subsection have been studied in detail. It has been also found that section Cerris had an ancient gene introgression with section Ilex, which led to the plastid capture. However, the specific evolutionary history of plastids in subsect. Campylolepides and section Ilex remains unclear. Our study performed low-coverage whole genome sequencing on 15 samples from section Ilex and integrated previously published data from subsect. Campylolepides and its relatives, resulting in a total of 325 resequencing data, of which 276 individuals were from three subsect. Campylolepides species and 19 populations. We assembled 325 plastids to perform phylogeographic analysis. The results were as follows:(1)There were shared haplotypes among three species of subsect. Campylolepides, but the plastid haplotypes of the entire subsect. Campylolepides form a monophyletic branch nested within section Ilex species which are distributed from central China to Liangshan, Sichuan.(2)A relictual haplotype of subsect. Campylolepides from the Liaodong Peninsula clustered with Q. pseudosetulosa, a specie of the section Ilex.(3)Both plastid capture events occurred in the middle Miocene, after which no plastid capture occurred between subsect. Campylolepides and section Ilex. It is hypothesized that subsect. Campylolepides and section Ilex have formed almost complete reproductive isolation. The study demonstrates that section Ilex and subsect. Campylolepides have undergone ancient plastid capture events in their evolution history, ultimately lead to the gradual formation of relatively independent evolutionary paths. |
