The complete chloroplast genome sequence of Rosa filipes (Rosaceae)

Abstract

To understand the genetic background of Rosa filipes, its complete chloroplast genome was determined in this study. The chloroplast genome of R. filipes is 156,624 bp in length with a large singlecopy region (LSC) of 85,754 bp, a small single-copy region (SSC) of 18,784 bp, and a pair inverted repeats (IRs) of 26,043 bp. The GC content is 37.2%. A total of 137 genes were identified, including 90 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis indicated that R. filipes is closely related to R. chinensis var. spontanea. ARTICLE HISTORY

Comparative phylogenetic analysis of oolong tea (Phoenix Dancong tea) using complete chloroplast genome sequences

“…The overall GC contents of the chloroplast genomes ranged from 37.29% to 37.31%, with the IR region being the highest (43.00%), followed by LSC (35.30%) and SSC (30.50%), which may be due to the presence of rRNAs (e.g., rrna4.5, rrna5, rrna23 and rrna16), which are GC-rich in the IR region. It should be noted that although the chloroplast genomes of most angiosperms generally encode 74 CDSs [ 37 ], P. Dancong tea, like other teas, harbors 90 CDSs (including accD , ycf1 , ycf2 , rpl23 and infA ), and other plants also have the same numbers, such as Rosa filipes [ 38 ] and Cerasus humilis [ 39 ]. Relative synonymous codon usage analysis showed that the starting codons of rps19 and ndhD had been replaced by GTG and ended with TAA.…”
