The complete chloroplast genome of a vulnerable species Champereia manillana (Opiliaceae)

Characterization of the complete plastomes of two flowering epiparasites (Phacellaria glomerata and P. compressa, Santalaceae, Santalales): gene content, organization and plastome degradation

“…Functional and physical loss of these genes is commonly observed in parasitic plants, which is regarded as an early response of plastomes in the evolution of a parasitic lifestyle [60]. Similar to the plastomes of previously studied hemiparasites in Santalales [16,17,19,[41][42][43][44] and other angiosperm orders [7,10,18], both P. compressa and P. glomerata have functionally lost all plastid-encoded ndh genes, suggesting that the NDH complex is the only gene group that has been entirely lost (physically or functionally) from the plastomes of photosynthetic parasites. The results further confirm the assumption that in parasitic plants with photosynthetic capacity, the ndh pathway is not indispensable [10,12,61].…”

“…Features of the P. compressa and P. glomerata plastomes were presented in Table 1. By comparison with the published plastomes of hemiparasitic plants in Santalales [16,17,19,[41][42][43][44], the size of the complete plastome, LSC, and IR in P. compressa and P. glomerata was similar to that of Champereia manillana, Dendrotrophe varians and Osyris alba, whilst slightly larger than that of the remaining species in the order (Table 1). As an obvious SSC reduction was observed in C. manillana, the SSC size of P. compressa and P. glomerate was closer to that of O. alba and D. varians.…”

“…To date, a total of 14 plastomes in Santalales (Additional file 1) have been published [16,17,19,[41][42][43][44]…”

“…In Santalales, only the autotrophic E. scandens plastome contains a relatively complete gene content, which encodes 112 genes, consisting of 79 proteincoding genes, 29 tRNA genes and four rRNA genes [44]. With functional gene totals ranging from 80 to 101 in P. compressa, P. glomerata, and other Santalales hemiparasites [16,17,19,[41][42][43][44], a size reduction compared to typically autotrophic angiosperms occurred in these hemiparasitic platomes, which made the plastome size of P. compressa and P. glomerata, as well as the hemiparasites in Santalales, slightly smaller than that of E. scandens (Table 1 & 2) and other autotrophic angiosperms.…”

The complete chloroplast genome of Yunnanopilia longistaminea (Opiliaceae), an endemic species in southwest China

“…Chloroplast genomes are widely used for phylogeny (Xue et al 2012), DNA barcoding (Dong et al 2014), genome evolution and species conservation (Dong et al 2013). Up to now, The chloroplast genome of many species has been reported, such as Champereia manillana (Yang et al 2017), Zanthoxylurm bungeanum (Liu and Wei 2017) and Fabaceae (Kato et al 2000). In this study, we reported the complete chloroplast genome sequence of Y. longistaminea based on the Illumina pair-end sequencing data.…”
