The complete plastid genome of the endangered species midget crabapple (Malus micromalus)

The midget crabapple (Malus micromalus) is endemic to Shaanxi and Shanxi Provinces of China. Like many other members of the Rosaceae, it is an important contributor to food production and nutrition. We determined the complete chloroplast genome sequences for M. micromalus using IIumina sequencing. The M. micromalus chloroplast has a total length of 159,834 bp; it consists of a large single copy (LSC) region of 87,950 bp, an inverted region A (IRa) of 26,354 bp, a short single copy (SSC) region of 19,176 bp, and an inverted region B (IRb) of 26,354 bp. The genome encodes 129 annotated genes, including 84 protein-coding genes and 45 tRNA. A phylogenomic analysis revealed that M. micromalus clustered with M. prunifolia within Malus.
