Mitochondrial DNA B Resour. 2021 Aug 4;6(9):2534-2535. doi: 10.1080/23802359.2021.1920497. eCollection 2021.

Abstract

Pennisetum flaccidum Grisebach is a typical high-quality forage and adrought-tolerant grass. In this study, we firstly reported the complete chloroplast (cp) genome of P. flaccidum, which was 138,336 bp in length, including a pair of inverted repeats (IR: 22,293 bp), a large single copy (LSC: 81,329 bp), and a small single copy (SSC: 12,421 bp) region. A total of 131 genes were annotated, containing seven rRNA genes, 38 tRNA genes, and 86 protein-coding genes. The GC content of the cp genome was 38.63%. The maximum-likelihood (ML) phylogenetic tree indicated that P. flaccidum was closely related to P. cetaceum in Poaceae.

Keywords: Pennisetum flaccidum; Poaceae; chloroplast genome; phylogenetic tree.
