The complete chloroplast genome sequence of Syringa oblata Lindl. var. alba Hort. ex Rehd. 1763 (Oleaceae)

Abstract

Syringa oblata var. alba is a shrub or a small tree from China with high ornamental, medicinal, and edible value. Here, we present its first complete chloroplast genome. The entire circular genome is 155,648 bp in length, with large single-copy (LSC) length of 86,247, small single-copy (SSC) length of 17,937, inverted repeat (IR) length of 25,732, and GC content of 37.9%. One hundred and thirty-two genes, including 88 protein-coding, 36 tRNA, and eight rRNA genes were predicted. A phylogenetic tree of 25 plant species was constructed based on the maximum-likelihood method, indicating that S. oblata var. alba, S. vulgaris, and S. oblata form a sister group. This study will provide valuable basic information for phylogeny, species identification, and varieties breeding of this species.
