Mitochondrial DNA B Resour 2024; 9:541-545. [PMID: 38665928 PMCID: PMC11044763 DOI: 10.1080/23802359.2024.2345773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 04/16/2024] [Indexed: 04/28/2024] Open
Abstract
Pandanus amaryllifolius of Pandanaceae, a plant native to Southeast Asia, has been domesticated for its health benefits and aromatic leaves. It is also used for phytoremediation and soil rehabilitation. However, genetic studies of this species are limited. This study aims to expand its genomic information by assembling and characterizing the complete chloroplast genome of P. amaryllifolius. The chloroplast genome, which was 157,839 bp long, contains a total of 133 genes, including 87 protein-coding (CDS), 38 tRNA, and eight rRNA genes. The overall G/C content was 37.7%. A phylogenetic analysis using 79 shared unique CDS revealed a monophyletic relationship in Pandanales. Based on the limited sampling size, Pandanus amaryllifolius was the first to diverge in Pandanaceae. The genomic data will be useful for future phylogenetic and evolutionary studies of Pandanaceae.

Abstract
The genus Sinosenecio B. Nordenstam is a group of perennial or sometimes annual or biennial herbs in the family Asteraceae. Here, we have successfully assembled and characterized the complete chloroplast (cp) genome of S. globigerus, which shows a typical quadratic structure with an overall GC content of 37.4%, comprising a pair of inverted repeat regions (IRs) of 24,848 bp, a large single-copy region (LSC) of 83,379 bp and a small single-copy region (SSC) of 18,180 bp. 133 genes were annotated, including 88 protein-coding genes, 37 tRNA genes and eight rRNA genes. Further nucleotide diversity analysis indicated that three genomic regions (accD-psaI, trnK-rps16, and ycf1) exhibited sufficient variability and thus could be recommended as valuable barcodes for the delimitation and identification of Sinosenecio species. Phylogenetic reconstruction presented clear interspecific relationships within Sinosenecio, which were supported to some extent by cytology, morphology and geographic distributions. Our study will provide valuable and high-quality genetic information to further elucidate the diversified mechanisms in Sinosenecio.

Characterization and Comparative Analysis of Chloroplast Genomes in Five Uncaria Species Endemic to China. Int J Mol Sci 2022; 23:ijms231911617. [PMID: 36232915 PMCID: PMC9569570 DOI: 10.3390/ijms231911617] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 09/22/2022] [Accepted: 09/27/2022] [Indexed: 11/09/2022] Open
Abstract
Uncaria, a perennial vine from the Rubiaceae family, is a typical Chinese traditional medicine. Currently, uncertainty exists over the Uncaria genus’ evolutionary relationships and germplasm identification. The complete chloroplast genomes of four Uncaria species mentioned in the Chinese Pharmacopoeia and Uncaria scandens (an easily confused counterfeit) were sequenced and annotated. The findings demonstrated that the whole chloroplast genome of Uncaria genus is 153,780–155,138 bp in full length, encoding a total of 128–131 genes, containing 83–86 protein-coding genes, eight rRNAs and 37 tRNAs. These regions, which include eleven highly variable loci and 31–49 SSRs, can be used to create significant molecular markers for the Uncaria genus. The phylogenetic tree was constructed according to protein-coding genes and the whole chloroplast genome sequences of five Uncaria species using four methods. The topology of the two phylogenetic trees showed no difference. The sequences of U. rhynchophylla and U. scandens are clustered in one group, while the U. hirsuta and U. macrophylla are clustered in another group. U. sessilifructus is clustered together with the above two small clades. New insights on the relationship were revealed via phylogenetic research in five Uncaria species. This study will provide a theoretical basis for identifying U. rhynchophylla and its counterfeits, as well as the species of the Uncaria genus. This research provides the initial chloroplast genome report of Uncaria, contributes to elucidating the chloroplast genome evolution of Uncaria in China.

Abstract
Background Ferula L. is one of the largest and most taxonomically complicated genera as well as being an important medicinal plant resource in the family Apiaceae. To investigate the plastome features and phylogenetic relationships of Ferula and its neighboring genera Soranthus Ledeb., Schumannia Kuntze., and Talassia Korovin, we sequenced 14 complete plastomes of 12 species. Results The size of the 14 complete chloroplast genomes ranged from 165,607 to 167,013 base pairs (bp) encoding 132 distinct genes (87 protein-coding, 37 tRNA, and 8 rRNA genes), and showed a typical quadripartite structure with a pair of inverted repeats (IR) regions. Based on comparative analysis, we found that the 14 plastomes were similar in codon usage, repeat sequence, simple sequence repeats (SSRs), and IR borders, and had significant collinearity. Based on our phylogenetic analyses, Soranthus, Schumannia, and Talassia should be considered synonymous with Ferula. Six highly divergent regions (rps16/trnQ-UUG, trnS-UGA/psbZ, psbH/petB, ycf1/ndhF, rpl32, and ycf1) were also detected, which may represent potential molecular markers, and combined with selective pressure analysis, the weak positive selection gene ccsA may be a discriminating DNA barcode for Ferula species. Conclusion Plastids contain abundant informative sites for resolving phylogenetic relationships. Combined with previous studies, we suggest that there is still much room for improvement in the classification of Ferula. Overall, our study provides new insights into the plastome evolution, phylogeny, and taxonomy of this genus.

Abstract
Background Sinosenecio B. Nordenstam (Asteraceae) currently comprises 44 species. To investigate the interspecific relationship, several chloroplast markers, including ndhC-trnV, rpl32-trnL, matK, and rbcL, are used to analyze the phylogeny of Sinosenecio. However, the chloroplast genomes of this genus have not been thoroughly investigated. We sequenced and assembled the Sinosenecio albonervius chloroplast genome for the first time. A detailed comparative analysis was performed in this study using the previously reported chloroplast genomes of three Sinosenecio species. Results The results showed that the chloroplast genomes of four Sinosenecio species exhibit a typical quadripartite structure. There are equal numbers of total genes, protein-coding genes and RNA genes among the annotated genomes. Per genome, 49–56 simple sequence repeats and 99 repeat sequences were identified. Thirty codons were identified as RSCU values greater than 1 in the chloroplast genome of S. albonervius based on 54 protein-coding genes, indicating that they showed biased usage. Among 18 protein-coding genes, 46 potential RNA editing sites were discovered. By comparing these chloroplast genomes' structures, inverted repeat regions and coding regions were more conserved than single-copy and non-coding regions. The junctions among inverted repeat and single-copy regions showed slight difference. Several hot spots of genomic divergence were detected, which can be used as new DNA barcodes for species identification. Phylogenetic analysis of the whole chloroplast genome showed that the four Sinosenecio species have close interspecific relationships. Conclusions The complete chloroplast genome of Sinosenecio albonervius was revealed in this study, which included a comparison of Sinosenecio chloroplast genome structure, variation, and phylogenetic analysis for related species. These will help future research on Sinosenecio taxonomy, identification, origin, and evolution to some extent.

Taxonomy, comparative genomics of Mullein (Verbascum, Scrophulariaceae), with implications for the evolution of Verbascum and Lamiales. BMC Genomics 2022; 23:566. [PMID: 35941527 PMCID: PMC9358837 DOI: 10.1186/s12864-022-08799-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 07/28/2022] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND The genus Verbascum L. (Scrophulariaceae) is distributed in Africa, Europe, and parts of Asia, with the Mediterranean having the most species variety. Several researchers have already worked on the phylogenetic and taxonomic analysis of Verbascum by using ITS data and chloroplast genome fragments and have produced different conclusions. The taxonomy and phylogenetic relationships of this genus are unclear. RESULTS The complete plastomes (cp) lengths for V. chaixii, V. songaricum, V. phoeniceum, V. blattaria, V. sinaiticum, V. thapsus, and V. brevipedicellatum ranged from 153,014 to 153,481 bp. The cp coded 114 unique genes comprising of 80 protein-coding genes, four ribosomal RNA (rRNA), and 30 tRNA genes. We detected variations in the repeat structures, gene expansion on the inverted repeat, and single copy (IR/SC) boundary regions. The substitution rate analysis indicated that some genes were under purifying selection pressure. Phylogenetic analysis supported the sister relationship of (Lentibulariaceae + Acanthaceae + Bignoniaceae + Verbenaceae + Pedaliaceae) and (Lamiaceae + Phyrymaceae + Orobanchaceae + Paulowniaceae + Mazaceae) in Lamiales. Within Scrophulariaceae, Verbascum was sister to Scrophularia, while Buddleja formed a monophyletic clade from (Scrophularia + Verbascum) with high bootstrap support values. The relationship of the nine species within Verbascum was highly supported. CONCLUSION Based on the phylogenetic results, we proposed to reinstate the species status of V. brevipedicellatum (Engl.) Hub.-Mor. Additionally, three genera (Mazus, Lancea, and Dodartia) placed in the Phyrymaceae family formed a separate clade within Lamiaceae. The classification of the three genera was supported by previous studies. Thus, the current study also suggests the circumscription of these genera as documented previously to be reinstated. The divergence time of Lamiales was approximated to be 86.28 million years ago (Ma) (95% highest posterior density (HPD), 85.12-89.91 Ma). The complete plastomes sequence data of the Verbascum species will be important for understanding the Verbascum phylogenetic relationships and evolution in order Lamiales.

Plastome structure of 8 Calanthe s.l. species (Orchidaceae): comparative genomics, phylogenetic analysis. BMC PLANT BIOLOGY 2022; 22:387. [PMID: 35918646 PMCID: PMC9347164 DOI: 10.1186/s12870-022-03736-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 06/29/2022] [Indexed: 06/01/2023]
Abstract
BACKGROUND Calanthe (Epidendroideae, Orchidaceae) is a pantropical genus distributed in Asia and Africa. Its species are of great importance in terms of economic, ornamental and medicinal values. However, due to limited and confusing delimitation characters, the taxonomy of the Calanthe alliance (Calanthe, Cephalantheropsis, and Phaius) has not been sufficiently resolved. Additionally, the limited genomic information has shown incongruences in its systematics and phylogeny. In this study, we used illumina platform sequencing, performed a de novo assembly, and did a comparative analysis of 8 Calanthe group species' plastomes: 6 Calanthe and 2 Phaius species. Phylogenetic analyses were used to reconstruct the relationships of the species as well as with other species of the family Orchidaceae. RESULTS The complete plastomes of the Calanthe group species have a quadripartite structure with varied sizes ranging between 150,105bp-158,714bp, including a large single-copy region (LSC; 83,364bp- 87,450bp), a small single-copy region (SSC; 16,297bp -18,586bp), and a pair of inverted repeat regions (IRs; 25,222bp - 26,430bp). The overall GC content of these plastomes ranged between 36.6-36.9%. These plastomes encoded 131-134 differential genes, which included 85-88 protein-coding genes, 37-38 tRNA genes, and 8 rRNA genes. Comparative analysis showed no significant variations in terms of their sequences, gene content, gene order, sequence repeats and the GC content hence highly conserved. However, some genes were lost in C. delavayi (P. delavayi), including ndhC, ndhF, and ndhK genes. Compared to the coding regions, the non-coding regions had more sequence repeats hence important for species DNA barcoding. Phylogenetic analysis revealed a paraphyletic relationship in the Calanthe group, and confirmed the position of Phaius delavayi in the genus Calanthe as opposed to its previous placement in Phaius. CONCLUSION This study provides a report on the complete plastomes of 6 Calanthe and 2 Phaius species and elucidates the structural characteristics of the plastomes. It also highlights the power of plastome data to resolve phylogenetic relationships and clarifies taxonomic disputes among closely related species to improve our understanding of their systematics and evolution. Furthermore, it also provides valuable genetic resources and a basis for studying evolutionary relationships and population genetics among orchid species.

[PMID: 35937412 PMCID: PMC9348943 DOI: 10.1155/2022/2194021] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 06/06/2022] [Accepted: 07/05/2022] [Indexed: 11/17/2022]
Abstract
Iris species, commonly known as rainbow flowers because of their attractive flowers, are extensively grown in landscape gardens. A few species, including Belamcanda chinensis, the synonym of I. domestica and I. tectorum, are known for their medicinal properties. However, research on the genomes and evolutionary relationships of Iris species is scarce. In the current study, the complete chloroplast (CP) genomes of I. tectorum, I. dichotoma, I. japonica, and I. domestica were sequenced and compared for their identification and relationship. The CP genomes of the four Iris species were circular quadripartite with similar lengths, GC contents, and codon usages. A total of 113 specific genes were annotated, including the ycf1 pseudogene in all species and rps19 in I. japonica alone. All the species had mononucleotide (A/T) simple sequence repeats (SSRs) and long forward and palindromic repeats in their genomes. A comparison of the CP genomes based on mVISTA and nucleotide diversity (Pi) identified three highly variable regions (ndhF-rpl32, rps15-ycf1, and rpl16). Phylogenetic analysis based on the complete CP genomes concluded that I. tectorum is a sister of I. japonica, and the subgenus Pardanthopsis with several I. domestica clustered into one branch is a sister of I. dichotoma. These findings confirm the feasibility of superbarcodes (complete CP genomes) for Iris species authentication and could serve as a resource for further research on Iris phylogeny.

Abstract
Coleanthus subtilis (Tratt.) Seidel (Poaceae) is an ephemeral grass from the monotypic genus Coleanthus Seidl, which grows on wet muddy areas such as fishponds or reservoirs. As a rare species with strict habitat requirements, it is protected at international and national levels. In this study, we sequenced its whole chloroplast genome for the first time using the next-generation sequencing (NGS) technology on the Illumina platform, and performed a comparative and phylogenetic analysis with the related species in Poaceae. The complete chloroplast genome of C. subtilis is 135,915 bp in length, with a quadripartite structure having two 21,529 bp inverted repeat regions (IRs) dividing the entire circular genome into a large single copy region (LSC) of 80,100 bp and a small single copy region (SSC) of 12,757 bp. The overall GC content is 38.3%, while the GC contents in LSC, SSC, and IR regions are 36.3%, 32.4%, and 43.9%, respectively. A total of 129 genes were annotated in the chloroplast genome, including 83 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. The accD gene and the introns of both clpP and rpoC1 genes were missing. In addition, the ycf1, ycf2, ycf15, and ycf68 were pseudogenes. Although the chloroplast genome structure of C. subtilis was found to be conserved and stable in general, 26 SSRs and 13 highly variable loci were detected, these regions have the potential to be developed as important molecular markers for the subfamily Pooideae. Phylogenetic analysis with species in Poaceae indicated that Coleanthus and Phippsia were sister groups, and provided new insights into the relationship between Coleanthus, Zingeria, and Colpodium. This study presents the initial chloroplast genome report of C. subtilis, which provides an essential data reference for further research on its origin.

Abstract
Buckwheat (Fagopyrum genus, Polygonaceae), is an annual or perennial, herbaceous or semi-shrub dicotyledonous plant. There are mainly three cultivated buckwheat species, common buckwheat (Fagopyrum esculentum) is widely cultivated in Asia, Europe, and America, while Tartary buckwheat (F. tataricum) and F. cymosum (also known as F. dibotrys) are mainly cultivated in China. The genus Fagopyrum is taxonomically confusing due to the complex phenotypes of different Fagopyrum species. In this study, the chloroplast (cp) genomes of three Fagopyrum species, F. longistylum, F. leptopodum, F. urophyllum, were sequenced, and five published cp genomes of Fagopyrum were retrieved for comparative analyses. We determined the sequence differentiation, repeated sequences of the cp genomes, and the phylogeny of Fagopyrum species. The eight cp genomes ranged, gene number, gene order, and GC content were presented. Most of variations of Fagopyrum species cp genomes existed in the LSC and SSC regions. Among eight Fagopyrum chloroplast genomes, six variable regions (ndhF-rpl32, trnS-trnG, trnC, trnE-trnT, psbD, and trnV) were detected as promising DNA barcodes. In addition, a total of 66 different SSR (simple sequence repeats) types were found in the eight Fagopyrum species, ranging from 8 to 16 bp. Interestingly, many SSRs showed significant differences especially in some photosystem genes, which provided valuable information for understanding the differences in light adaptation among different Fagopyrum species. Genus Fagopyrum has shown a typical branch that is distinguished from the Rumex, Rheum, and Reynoutria, which supports the unique taxonomic status in Fagopyrum among the Polygonaceae. In addition, phylogenetic analysis based on the cp genomes strongly supported the division of eight Fagopyrum species into two independent evolutionary directions, suggesting that the separation of cymosum group and urophyllum group may be earlier than the flower type differentiation in Fagopyrum plants. The results of the chloroplast-based phylogenetic tree were further supported by the matK and Internal Transcribed Spacer (ITS) sequences of 17 Fagopyrum species, which may help to further anchor the taxonomic status of other members in the urophyllum group in Fagopyrum. This study provides valuable information and high-quality cp genomes for identifying species and evolutionary analysis for future Fagopyrum research.

Complete Chloroplast Genome Sequence of Fortunella venosa (Champ. ex Benth.) C.C.Huang (Rutaceae): Comparative Analysis, Phylogenetic Relationships, and Robust Support for Its Status as an Independent Species. FORESTS 2021.

Abstract
Fortunella venosa (Rutaceae) is an endangered species endemic to China and its taxonomic status has been controversial. The genus Fortunella contains a variety of important economic plants with high value in food, medicine, and ornamental. However, the placement of Genus Fortunella into Genus Citrus has led to controversy on its taxonomy and Systematics. In this present research, the Chloroplast genome of F. venosa was sequenced using the second-generation sequencing, and its structure and phylogenetic relationship analyzed. The results showed that the Chloroplast genome size of F. venosa was 160,265 bp, with a typical angiosperm four-part ring structure containing a large single copy region (LSC) (87,597 bp), a small single copy region (SSC) (18,732 bp), and a pair of inverted repeat regions (IRa\IRb) (26,968 bp each). There are 134 predicted genes in Chloroplast genome, including 89 protein-coding genes, 8 rRNAs, and 37 tRNAs. The GC-content of the whole Chloroplast genome was 43%, with the IR regions having a higher GC content than the LSC and the SSC regions. There were no rearrangements present in the Chloroplast genome; however, the IR regions showed obvious contraction and expansion. A total of 108 simple sequence repeats (SSRs) were present in the entire chloroplast genome and the nucleotide polymorphism was high in LSC and SSC. In addition, there is a preference for codon usage with the non-coding regions being more conserved than the coding regions. Phylogenetic analysis showed that species of Fortunella are nested in the genus of Citrus and the independent species status of F. venosa is supported robustly, which is significantly different from F. japonica. These findings will help in the development of DNA barcodes that can be useful in the study of the systematics and evolution of the genus Fortunella and the family Rutaceae.
