Highbush blueberry is a small berry fruit tree belonging to the family Ericaceae and genus Vaccinium, which fruit has high nutritional value. High-throughput sequencing technology was applied in this study to sequence and assemble the whole chloroplast genome of the southern highbush blueberry variety sharpblue. The results of the study showed that the circular genome of sharpblue is 170,737 bp in length, and the GC content of the genome was 36.8%. The complete chloroplast genome of sharpblue has consisted of two inverted repeat regions (IRs), a large single-copy region (LSC, 31, 076 bp), and a small single-copy region (SSC, 3, 044 bp). The chloroplast genome contained a total of 144 functional genes, including 100 mRNA genes, eight rRNA genes, and 36 tRNA genes. In addition, V. corymbosum and V. oldhamii were clustered into one group in this phylogenetic analysis which indicated that they have a close evolutionary relationship. The findings of this investigation are a significant reference source for the phylogeny and evolutionary origin of the Ericaceae family.
Keywords: Vaccinium corymbosum; chloroplast genome; phylogenetic analysis.
