“…This sequence represents the fourth complete chloroplast genome to be sequenced in Gesneriaceae. When compared to the firstly sequenced representatives, Haberlea rhodopensis [ 8 ], Dorcoceras hygrometricum [ 26 ], and Lysionotus pauciflorus [ 39 ], the four chloroplast genomes are comparable in terms of their gene content, genome organization, and structure despite some slight differences such as genome size ( Table 5 ). Lysionotus pauciflorus (153,856 bp) was found to be the most extensive, followed by Dorcoceras hygrometricum (153,493 bp) and Streptocarpus teitensis (153,207 bp), while Haberlea rhodopensis (153,099 bp) was the shortest.…”

Streptocarpus teitensis (Gesneriaceae) is an endemic species listed as critically endangered in the International Union for Conservation of Nature (IUCN) red list of threatened species. However, the sequence and genome information of this species remains to be limited. In this article, we present the complete chloroplast genome structure of Streptocarpus teitensis and its evolution inferred through comparative studies with other related species. S. teitensis displayed a chloroplast genome size of 153,207 bp, sheltering a pair of inverted repeats (IR) of 25,402 bp each split by small and large single-copy (SSC and LSC) regions of 18,300 and 84,103 bp, respectively. The chloroplast genome was observed to contain 116 unique genes, of which 80 are protein-coding, 32 are transfer RNAs, and four are ribosomal RNAs. In addition, a total of 196 SSR markers were detected in the chloroplast genome of Streptocarpus teitensis with mononucleotides (57.1%) being the majority, followed by trinucleotides (33.2%) and dinucleotides and tetranucleotides (both 4.1%), and pentanucleotides being the least (1.5%). Genome alignment indicated that this genome was comparable to other sequenced members of order Lamiales. The phylogenetic analysis suggested that Streptocarpus teitensis is closely related to Lysionotus pauciflorus and Dorcoceras hygrometricum.

The genus Sedum, with about 470 recognized species, is classified in the family Crassulaceae of the order Saxifragales. Phylogenetic relationships within the Saxifragales are still unresolved and controversial. In this study, the plastome of S. plumbizincicola was firstly presented, with a focus on the structural analysis of rrn operon and phylogenetic implications within the order Saxifragaceae. The assembled complete plastome of S. plumbizincicola is 149,397 bp in size, with a typical circular, double-stranded, and quadripartite structure of angiosperms. It contains 133 genes, including 85 protein-coding genes (PCGs), 36 tRNA genes, 8 rRNA genes, and four pseudogenes (one ycf1, one rps19, and two ycf15). The predicted secondary structure of S. plumbizincicola 16S rRNA includes three main domains organized in 74 helices. Further, our results confirm that 4.5S rRNA of higher plants is associated with fragmentation of 23S rRNA progenitor. Notably, we also found the sequence of putative rrn5 promoter has some evolutionary implications within the order Saxifragales. Moreover, our phylogenetic analyses suggested that S. plumbizincicola had a closer relationship with S. sarmentosum than S. oryzifolium, and supported the taxonomic revision of Phedimus. Our findings of the present study will be useful for further investigation of the evolution of plastid rRNA operon and phylogenetic relationships within Saxifragales.

Hemiboea pterocaulis is a unique species only found in Guilin, Guangxi, China. In this study, we sequenced and assembled the complete chloroplast genome of H. pterocaulis and revealed its phylogenetic relationship with other Hemiboea species. The chloroplast genome sequence of H. pterocaulis is 153,159 bp in length and comprises a large single-copy (LSC) region of 84,178 bp, a small single-copy (SSC) region of 18,087 bp, and a pair of inverted repeat (IR) regions, each with a length of 25,447 bp. It has a total GC content of 37.6% and encodes 132 genes, including 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The phylogenetic relationships based on the complete chloroplast genome sequences of Hemiboea taxa indicate that H. pterocaulis is most closely related to H. suiyangensis , indicating that H. pterocaulis is an independent species and is separated from the H. subcapitata complex. These results provide valuable insights into the phylogeny, species divergence, and delimitation of the Hemiboea genus.
