The complete chloroplast genome sequence of Passiflora xishuangbannaensis (Passifloraceae), a vine endemic to Yunnan, China

Abstract

Passiflora xishuangbannaensis , Passiflora subgenus Decaloba , is a very rare endemic to the Yunnan, China. Here we report and characterize the complete chloroplast (cp) genome sequence of P. xishuangbannaensis to provide genomic resources useful for promoting its conservation and systematics. The complete genome is 135,742 bp in length and the overall GC content is 37.1%. The cp genome sequence has a typical quadripartite structure, comprising two inverted repeats (IRs: 20,604 bp) regions, which are separated by a small single-copy (SSC: 13,159 bp) region and a large single-copy (LSC: 81,375 bp) region. Moreover, a total of 122 functional genes were annotated, including 77 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The phylogenetic analysis recovered P. xishuangbannaensis as a member of subgenus Decaloba .

Plastid genome of Passiflora tripartita var. mollissima (poro-poro) from Huánuco, Peru

“…mollissima consisted of A = 30.79%, T(U) = 32.34%, C = 18.67% and G = 18.20%. The overall AT content of the plastid genome was 63.13%, whereas the overall GC content was 36.87% as similar to that of other reported chloroplast genomes from the same family, such as 36.90% in P. arbelaezii (Shrestha et al, 2019), 37% in P. edulis and P. serrulata (Cauz- Santos et al, 2017;Mou et al, 2021), 37.03% in P. caerulea (Niu et al, 2021), and 37.1% in P. xishuangbannaensis (Hao & Wu, 2021).…”

“…The SSC region is 121 bp, 140 bp, 359 bp, and 754 bp longer than that of P. caerulea, P. edulis, P. xishuangbannaensis, and P. arbelaezii, respectively. The IRs regions are 6,024 bp, 6,050 bp, and 11,600 longer than that of P. caerulea, P. edulis, and P. xishuangbannaensis, respectively; however, it is 2,972 bp shorter than that of P. arbelaezii (Cauz- Santos et al, 2017;Shrestha et al, 2019;Hao & Wu, 2021;Niu et al, 2021). The plastome structure of the P. tripartita var.…”

“…In recent years, declining genome sequencing costs resulted in more than 780 complete plant genomes of different species becoming available (Marks et al, 2021;Sun et al, 2022). Recently, some Passiflora plastid genomes such as Passiflora edulis (Cauz- Santos et al, 2017), Passiflora xishuangbannaensis (Hao & Wu, 2021), Passiflora caerulea (Niu et al, 2021), Passiflora serrulata (Mou et al, 2021), Passiflora foetida (Hopley et al, 2021), and Passiflora arbelaezii (Shrestha et al, 2019), became publicly available. However, despite the scarcity of genomic information on underutilized crops (Gioppato et al, 2019), we have only begun to investigate the genomics of plants of great importance for plant breeding programs.…”

First Report of the Plastid Genome of <em>Passiflora tripartita</em> var. <em>mollissima</em> (poro-poro) from Huánuco, Peru

“…The IRs regions are 6,024 bp, 6,050 bp, and 11,600 longer than that of P. caerulea, P. edulis, and P. xishuangbannaensis, respectively; however, it is 2,972 bp shorter than that of P. arbelaezii [19-21, 24, 29]. The overall GC content of the plastome (36.87%) was similar to that of other reported chloroplast genomes from the same family, such as 36.90% in P. arbelaezii [24], 37% in P. edulis and P. serrulata [19,22], 37.03% in P. caerulea [21], and 37.1% in P. xishuangbannaensis [20].…”
