Abstract EN
Salix wilsonii is an important ornamental willow tree widely distributed in China.
In this study, an integrated circular chloroplast genome was reconstructed for S.
wilsonii based on the chloroplast reads screened from the whole-genome sequencing data generated with the PacBio RSII platform.
The obtained pseudomolecule was 155,750 bp long and had a typical quadripartite structure, comprising a large single copy region (LSC, 84,638 bp) and a small single copy region (SSC, 16,282 bp) separated by two inverted repeat regions (IR, 27,415 bp).
The S.
wilsonii chloroplast genome encoded 115 unique genes, including four rRNA genes, 30 tRNA genes, 78 protein-coding genes, and three pseudogenes.
Repetitive sequence analysis identified 32 tandem repeats, 22 forward repeats, two reverse repeats, and five palindromic repeats.
Additionally, a total of 118 perfect microsatellites were detected, with mononucleotide repeats being the most common (89.83%).
By comparing the S.
wilsonii chloroplast genome with those of other rosid plant species, significant contractions or expansions were identified at the IR-LSC/SSC borders.
Phylogenetic analysis of 17 willow species confirmed that S.
wilsonii was most closely related to S.
chaenomeloides and revealed the monophyly of the genus Salix.
The complete S.
wilsonii chloroplast genome provides an additional sequence-based resource for studying the evolution of organelle genomes in woody plants.
