Complete chloroplast genome of Rhododendron pulchrum, an ornamental medicinal and food tree

Abstract

The semi-evergreen azalea, Rhododendron pulchrum, a valuable horticultural and medicinal plant species. Using next-generation sequencing, applying a combination of de novo and reference-guided assembly, we sequenced its complete chloroplast genome. Our study reveals that R. pulchrum have a typical cp genome of 136,249 bp in length, without inverted repeat regions. A total of 73 genes, 42 of which are protein coding genes, 29 tRNA genes, two rRNA genes were identified. The GC content of the whole genome is 35.98%. Phylogenetic analysis indicates that R. pulchrum is closely related to the species of Vaccinium oldhamii and Vaccinium macrocarpon.
