Mitochondrial DNA B Resour. 2021 Jun 28;6(8):2105-2106. doi: 10.1080/23802359.2021.1903355. eCollection 2021.

Abstract

The complete chloroplast genome of Pennisetum centrasiaticum was sequenced and reported here. The total genome size was 138,294 bp in length, containing a large single-copy region of 81,229 bp, a small single-copy region of 12,419 bp, and a pair of inverted repeat regions of 22,288 bp. The GC content of P. centrasiaticum chloroplast genome was 38.6%. It encodes a total of 119 unique genes, including 81 protein-coding genes, 34 tRNA genes, and four rRNA genes. Phylogenetic analysis showed a strong sister relationship with Cenchrus ciliaris and Cenchrus purpureus. Our findings provide fundamental information for further evolutionary and phylogenetic researches of P. centrasiaticum.

Keywords: Pennisetum centrasiaticum; chloroplast genome; phylogenetic analysis.
