Abstract
Amomum villosum Lour. (Zingiberaceae) is an important edible and medicinal crop. The complete chloroplast (cp) genome of A. villosum was determined using Illumina sequencing platform. The size of whole cp genome was 164,069 bp, containing a small single copy (SSC) region of 15,353 bp and a large single copy (LSC) region of 88,798 bp, which were separated by a pair of inverted repeat (IRs) regions (29,959 bp). The A. villosum cp genome contained 133 genes, including eight ribosomal RNA genes (4 rRNA species), 38 transfer RNA genes (30 tRNA species) and 87 protein-coding genes (79 PCG species). The overall GC content of A. villosum cp genome is 36.05%. To investigate the evolution status of A. villosum, as well as Zingiberales, a phylogenetic tree with A. villosum and other 21 species was constructed based on their complete chloroplast genomes. Phylogenetic analysis revealed that A. villosum was closely related to Amomum krervanh.
