The complete chloroplast genome of Rhododendron delavayi (Ericaceae)

Abstract

Rhododendron delavayi, as a member of Ericaceae family, has been widely used as an important garden flower. The cp genome of R. delavayi exhibited a typical quadripartite cycle with 193,798 bp, comprising of a pair of inverted repeats (IRa and IRb) of 15,494 bp intersected by a large single copy (LSC) region of 160,234 bp and a quite small single copy region of 2576 bp. Totally, 123 unique genes were assembled in this cp genome, including 80 protein genes, 35 tRNAs and 8 rRNAs. Out of these assembled genes, 88 genes (71.54%) were single copy. Phylogenetic analysis based on 14 cp genome of related species showed that the R. delavayi was closely related to Vaccinium oldhamii. This study provides important information for future evolution, genetic and molecular biology studies of Rhododendron.

Complete plastid genome of Rhododendron griersonianum, a critically endangered plant with extremely small populations (PSESP) from southwest China

“…Our study represents the first look into the complete plastid genome of R. griersonianum, which is the third plastid genome in genus Rhododendron, with 12,669 bp longer than Rhododendron delavayi (Liu et al 2020) and 70,218 bp longer than Rhododendron  pulchrum (Shen et al 2019). The availability of R. griersonianum plastid genome will greatly contribute to the evolutionary and phylogenetic analysis, and will benefit future studies related to the development and horticultural utilization in the genus Rhododendron.…”

“…GetOrganelle v1.7.0 (Jin et al 2018), SMARTdenovo (Ruan 2018) and fmlrc (Wang et al 2018) were used to assemble, polish and correct the genome. Annotation was performed using PGA (Qu et al 2019), then manually corrected with the plastid genome R. delavayi (Liu et al 2020) as reference. The final length of the plastid genome is 206,467 bp, which encodes 118 unique genes, including 78 protein-coding genes, 36 tRNA and 4 rRNA genes, with a GC content of 35.8%, and comprising of a SSC (small single copy) region of 315 bp, a LSC (large single copy) region of 111,218 bp, and a pair of IR regions of 94,934 bp.…”

Characterization of the complete chloroplast genome sequence of Koelreuteria bipinnata

“…Previously, the studies regarding K. bipinnata were mainly focus on its tissue culture (Feng, Li, et al 2009;Cao et al 2018), few data are currently available about its genomic information. In plants, the chloroplast genome is helpful for population genetics study, species-level identification, and phylogenetic analysis (Liu et al 2020;Mo et al 2020). Here, we de novo assembled the complete chloroplast genome of K. bipinnata, and analyzed its relationship with closely related species.…”
