Salix kochiana Trautvetter 1837 is one of the highest value shrubs present in northern China with important economic and ecological benefits. This study revealed the structural characteristics and phylogenetic relationships of chloroplast genes in S. kochiana Trautv. The results showed that the length of the complete chloroplast genome was 155,657 bp, which was a typical circular double-stranded structure, including an 84,458 bp large single-copy region (LSC), a 16,221 bp small single-copy region (SSC) and a 27,489 bp pair of inverted repeat regions (IRA and IRB). The chloroplast genome contains 48,757 A bases, 28,017 G bases, 49,843 T bases, and 29,040 C bases, with a GC content of 36.66%. Through bioinformatics annotation, a total of 126 genes were found in the chloroplast genome, including 81 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis showed that S. kochiana Trautv. was closely related to S. triandroides.

Salix kochiana Trautvetter 1837 is one of the highest value shrubs present in northern China with important economic and ecological benefits. This study revealed the structural characteristics and phylogenetic relationships of chloroplast genes in S. kochiana Trautv. The results showed that the length of the complete chloroplast genome was 155,657 bp, which was a typical circular double-stranded structure, including an 84,458 bp large single-copy region (LSC), a 16,221 bp small single-copy region (SSC) and a 27,489 bp pair of inverted repeat regions (IRA and IRB). The chloroplast genome contains 48,757 A bases, 28,017 G bases, 49,843 T bases, and 29,040 C bases, with a GC content of 36.66%. Through bioinformatics annotation, a total of 126 genes were found in the chloroplast genome, including 81 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis showed that S. kochiana Trautv. was closely related to S. triandroides ., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2022 The Author(s).
