The complete chloroplast genome sequence of Oryza eichingeri (Poaceae)

Abstract

The complete chloroplast genome sequence of Oryza eichingeri (GenBank accession number: KX085496) was generated by de novo assembly with low-coverage whole-genome sequence data. The chloroplast genome is 134,821 bp in length and showed conserved typical chloroplast structure. The cpDNA contained four rRNA, 39 tRNA, and 79 unique protein-coding genes. Seventeen genes contain one intron, only ycf3 contains two introns; rps12 is trans-spliced, one of its exons is in the LSC region (5′_end) and the two reside in the IR regions (3′_end) separated. A pair of gene ndhH, due to the 5′ part of ndhH which overlaps the IR/SSC junctions, was two unique genes. The AT content of O. eichingeri cp genome is 61%. Phylogenomic analysis showed that O. eichingeri is closely related to O. officinalis . The complete cpDNA of O. eichingeri provides essential and important DNA molecular data for further phylogenetic and evolutionary analysis for the genus Oryza .

The complete chloroplast genome of pearl millet (Pennisetum glaucum (L.) R. Br.) and comparative analysis within the family poaceae

“…As shown in Figure 1, the P. glaucum cp genome has a typical quadripartite structure composed of the LSC, SSC and a pair of IR regions, indicating that the assembled P. glaucum cp genome sequence represented full coverage with no abnormalities. Several chloroplast genome sequences have been reported from the Poaceae family (Cao et al 2017;Huang et al 2017;Liu et al 2017). The cp genome of P. glaucum is highly conserved, with identical gene content and gene order and genomic structure comprising four parts as reported as angiosperm cp genomes.…”
