Characterization of the complete chloroplast genome of Betula pendula purple rain (betulaceae).

purple rain is a variety of that is native to Europe and has important ornamental and economic value. In this study, we sequenced the complete chloroplast genome of purple rain. This genome had a typical quadripartite structure with 160,552 bases, including a large single copy (LSC) region of 89,433 bases, a small single copy (SCC) region of 19,007 bases and two inverted repeat (IR) regions of 26,056 bases. The GC content of the chloroplast genome was 36% and contained 124 genes, including 79 protein-coding genes, 8 rRNA genes and 37 tRNA genes. The maximum likelihood phylogenetic analysis of reported chloroplast genomes showed that purple rain was most closely related to and .
