Characterization of the Complete Chloroplast Genome of Hygroryza aristata (Retz.) Nees ex Wight & Arn. (Zizaniinae, Poaceae).

The complete chloroplast genome sequence of Hygroryza aristata was sequenced, assembled and published for the first time here. The chloroplast genome was 135,681 bp in length and comprised of a large single-copy (LSC, 81,532 bp) region and a small single-copy (SSC, 12,383 bp) region interspersed by two inverted repeats (IRs, 20,883 bp). Gene annotation resulted in the identification of 113 unique genes including 79 protein-coding genes, 30 transfer RNA (tRNA) genes, and four ribosomal RNA (rRNA) genes. In addition, 118 simple sequence repeats (SSRs) and 47 long repeats were identified. Phylogenetic analysis based on maximum likelihood analysis (ML) resolved the placement of H. aristata sister to a clade of Rhynchoryza subulata and Zizania.
