Abstract

Morus alba is an important medicinal plant that is used to treat human diseases. The complete chloroplast (cp) genome of M. alba was assembled based on the Illumina sequencing reads. The cp genome of M. alba was 159,290 bp and contained two short inverted repeat regions (25,690 bp) which were separated by a small single copy region (19,845 bp) and a large single copy region (88,065 bp). The cp genome encodes 111 unique genes, including 77 protein-coding genes, 30 transfer RNA genes and four ribosomal RNA genes. The topology of the phylogenetic tree showed that M. alba is closely clustered with species M. cathayana and M. mongolica.

Keywords: Morus alba; chloroplast genome; medicinal and edible plant; phylogenetic analysis.
