“…In order to ascertain phylogenetic position of O. cotinifolia in Gesneriaceae, the chloroplast genome sequences of 24 Gesneriaceae species were downloaded from NCBI GenBank database, and the ML tree was constructed using Fraxinus sieboldiana and F. insularis (Scrophulariaceae) as outgroups. Previous phylogenetic studies indicated that Thamnocharis embedded into Oreocharis , and T. esquirolii was a synonym of O. esquirolii (Wang et al 2010 ; Möller et al 2011 ; Meng et al 2019 ). Phylogenetic analysis of our study also revealed that O. cotinifolia is a sister species to O. mileensis ( Figure 1 ), and supported resurrection of the name O. esquirolii from T. esquirolii .…”

Oreocharis cotinifolia is a plant herb with a small population and narrow distribution range in southeast China. It is listed as one of the class 1 key protected wild plants in China and designated as a critically endangered species. In this study, we assembled the complete chloroplast genome of O. cotinifolia using data from high-throughput Illumina sequencing. The cp genome is 153,577 bp in length and includes two inverted repeats (IRs) of 25,292 bp, separated by a large single-copy region (LSC) and a small single-copy region (SSC) that are 84,898 bp and 18,095 bp, respectively. The GC content is 37.42%. The genome encodes 128 functional genes, including 87 protein-coding, 37 tRNA, and 4 rRNA genes. Maximum likelihood analysis showed that O. cotinifolia is closely related to the congeneric O. mileensis . The complete chloroplast genome will contribute to further studies on phylogeny and conservation of O. cotinifolia and related taxa in Oreocharis of Gesneriaceae.

Petrocodon and Primulina are two characteristic genera of Gesneriaceae that exhibit remarkable species and floral diversity, and high endemism across the Sino-Vietnamese Limestone Karsts. To better understand the evolution of limestone gesneriad plastomes, we report nine complete plastomes of seven Primulina and two Petrocodon which have never been assembled before. The newly generated plastomes range from 152,323 to 153,786 bp in size and display a typical quadripartite structure. To further explore the plastome evolution across Gesneriaceae, we assembled five additional plastomes from public reads data and incorporated 38 complete Gesneriaceae plastomes available online into comparative and phylogenomic analyses. The comparison of 52 Gesneriaceae plastomes reveals that not only Primulina and Petrocodon but all gesneriad genera analyzed are highly conserved in genome size, genome structure, gene contents, IR boundary configurations, and codon usage bias. Additionally, sliding window analyses were implemented across alignments of Primulina and Petrocodon for identifying highly variable regions, providing informative markers for future studies. Meanwhile, the SSRs and long repeats of Gesneriaceae plastomes were characterized, serving as useful data in studying population and repetitive sequence evolutions. The results of plastome phylogenetics represent a preliminary but highly resolved maternal backbone genealogy of Primulina and the Old World subtribes of Gesneriaceae.

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.
