Recently, researchers have shown intensive interest in the complicated interactions. Linalool, an acyclic monoterpene, is one of the common flavor-related volatiles across the plant kingdom. In this review, we summarized the biosynthesis and transcriptional regulation of terpenoids, and then focused on the biological function of linalool in plant–insect interactions. We found that flowers emitting linalool as the dominant volatile appeal to broad assemblages of pollinators, while some pollinators typically have strong preferences for these flowers as well. Hereinto, moths and bees are the main pollinators of linalool-dominant flowers. Additionally, linalool produced by plants could defend against insect pests and pathogens. It is noteworthy that the two enantiomers of linalool have distinct functions. (S)-(+)-linalool mainly attracts pollinators, while (R)-(−)-linalool seems to act as insect repellents. Further research on the biofunctional diversity and genetic mechanisms of linalool enantiomers will reveal the complexity of plant survival strategies, and the increasing understanding of the molecular mechanisms underlying their biosynthesis and transcriptional regulation will provide theoretical foundation and practical basis for directional transformation of plants.","PeriodicalId":17087,"journal":{"name":"Journal of Systematics and Evolution","volume":"61 3","pages":"538-549"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jse.12930","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50140941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While “reverse” U-to-C editing was recorded in other seed-free plants such as hornworts, quillworts, and ferns, it was not observed in spikemosses. However, no comprehensive study on the association between RNA editing and other genomic features was conducted for the organelle genomes of spikemosses. Here, we report thousands of C-to-U editing sites from plastomes and mitogenomes of two species: 1767 and 2394 edits in Selaginella remotifolia, and 4091 and 2786 edits in Selaginella nipponica, respectively. Comparative analyses revealed two different editing frequencies among plastomes, but one similar frequency in mitogenomes. The different editing frequency in the Selaginella organelle genomes is related to the nonsynonymous substitution rate and the genome structural complexity. The high guanine and cytosine (GC) content caused by GC-biased mutations in organelle genomes might be related to the absence of U-to-C editing in Selaginellaceae. Using RNA-seq and whole-genome data, we screened the pentatricopeptide repeat (PPR) family and discovered that the number of aspartic acid–tyrosine–tryptophan (DYW) domain-containing PPR proteins corresponded roughly to the editing abundance in the Selaginella organelle genomes. Consequently, we hypothesize that associated evolution among RNA editing, GC-biased mutation in organelle genomes, and the PPR protein family encoded in the nuclear genome, is probably triggered by the aberrant DNA repair system in Selaginellaceae. Our study provides new insights into the association between organelle and nuclear genomes in Selaginellaceae, which would contribute to understanding the evolution of post-transcriptional modifications of organelle genomes in land plants.","PeriodicalId":17087,"journal":{"name":"Journal of Systematics and Evolution","volume":"61 5","pages":"890-905"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50119804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Precise establishment of orthologs is a critical challenge for RRS, especially when a reference genome is absent. The proportion of shared heterozygous sites across samples is an alternative criterion for filtering paralogs. In the prevailing pipeline for variant calling of RRS data – PYRAD/IPYRAD, maxSH is an often overlooked parameter with implications to detecting and filtering paralogs according to shared heterozygosity. Using empirical genotyping by sequencing data of two primroses (Primula alpicola Stapf and Primula florindae Ward) and their putative hybrids, and extra data sets of Californian golden cup oaks, we explore the impact of maxSH on filtering paralogs and further downstream analyses. Our study sheds light on the simultaneous validity and risk of filtering paralogs using maxSH, and its significant effects on downstream analyses of outlier detection, population assignment, and demographic modeling, emphasizing the importance of attention to detail during bioinformatic processes. The mutual confirmation between results of population assignment and demographic modeling in this study suggested maxSH = 0.10 has a potentially excessive and asymmetrical effect on the removal of truly shared heterozygous sites as paralogs. These results indicate that hybridization origin hypotheses of putative hybrids represented by results with maxSH = 0.25 and 0.50 are more credible. In conclusion, we revealed the critical hazard of paralogs filtration according to sharing heterozygosity at first, so that we propose to use specific protocols, rather than maxSH, to filter potential paralogs for closely related lineages.","PeriodicalId":17087,"journal":{"name":"Journal of Systematics and Evolution","volume":"61 5","pages":"906-918"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50119805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All these data were organized into HelDB, a database where Helitrons can be explored with a user-friendly Web interface and related software. Based on these data, further analysis showed that the number or the cumulative length of Helitrons is positively correlated with genome size. Helitrons had experienced two expansion periods in plants, with the first occurring 20–30 Ma and peaking at approximately 24 Ma. The second expansion occurred in the last 4 million years. The expansions might be due to stimulation of paleogeographic environment. Detailed investigation of gene capture by Helitrons in Brassicaceae and Solanaceae plants showed that the captured genes showed diverse functions. Interestingly, metal ion binding function was enriched in these captured genes in most species. This phenomenon might be due to the need for binding of divalent metal ions to the Rep domain required for Helitron transposition. This study improves our knowledge of the landscape and evolution of Helitron transposons in plants and paves a way for further functional studies of this kind of transposable element.","PeriodicalId":17087,"journal":{"name":"Journal of Systematics and Evolution","volume":"61 5","pages":"919-931"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50119365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, despite their high phylogenetic relatedness, S. benthamiana s.str. and Santolina ericoides can still be considered as distinct species due to clear morphological and ecological differentiation.

Phylogenetic trees generated using ASTRAL and Bayesian inference were used to test the monophyly of subgenera/sections. These trees provide the basis for ancestral character state reconstructions and phylogenetic correlation analyses for five morphological characters and characters related to the moisture habitat, scored from the literature and by specimen inspection. Many of these characters exhibit statistically significant phylogenetic signal. Significant correlations were found between the limbidium (phyllid/leaf border of the gametophyte) and habitat moisture niche breadth, which could be interpreted as the more extensive limbidium enabling species to survive across a wider variety of habitats. We also found correlations between costa anatomy, peristome morphology, and the limbidium, which could reflect the evolutionary recruitment of genetic networks from the gametophyte to the sporophyte phase. The correlation found between average habitat moisture and the sexual system indicates that dioicous and polyoicous species are more likely to be found in moist habitats and that these higher moisture levels could be particularly, reproductively advantageous to species with separate sexes.","PeriodicalId":17087,"journal":{"name":"Journal of Systematics and Evolution","volume":"61 5","pages":"868-889"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50149481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we sought to understand the phenotypic evolution of key traits in Rhinolophidae (horseshoe bats) using phylogenetic comparative methods. We aimed to test the phylogenetic signals of traits, and evaluated the best-fit evolutionary models given the data for each trait considering different traits may evolve under different models (i.e., Brownian Motion [BM], Ornstein-Uhlenbeck [OU], and Early Burst [EB]) and reconstruct ancestral character states. We examined how phenotypic characters are associated with echolocation calls and minimum detectable prey size. We measured 34 traits of 10 Asian rhinolophids species (187 individuals). We found that the majority of traits showed a high phylogenetic signal based on Blomberg′s K and Pagel′s λ, but each trait may evolve under different evolutionary models. Sella traits were shown to evolve under stabilizing selection based on OU models, indicating sella traits have the tendency to move forward along the branches toward some medial value in equilibrium. Our findings highlight the importance of sella characters in association with echolocation call emissions in Rhinolophidae, as calls are important for spatial cognition and also influence dietary preferences. Minimum detectable prey size in Rhinolophidae was associated with call frequency, bandwidth, call duration, wingspan, and wing surface area. Ultimately, understanding trait evolution requires sensitivity due to the differential selective pressures which may apply to different characteristics.","PeriodicalId":17087,"journal":{"name":"Journal of Systematics and Evolution","volume":"61 4","pages":"719-732"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50153159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hybridization and introgression events of East Asian Vitis are not well investigated, particularly at the genome-wide scale. The phylogenetic relationships of East Asian Vitis are herein explored using nuclear and plastid genome data based on target enrichment (Hyb-Seq). Seven major clades are recognized for East Asian Vitis based on the nuclear phylogenetic trees, but there is topological incongruence between concatenated and coalescent analyses. Furthermore, significant cytonuclear discordance is observed within East Asian Vitis. Species network analyses identified several hybridization events within East Asian Vitis. These interspecific hybridization events may have caused the topological discordances and relatively low support detected in our analyses. Ecological niche modeling shows that most of the diversification of East Asian Vitis species is driven by temperature and precipitation environmental variables. Sympatric parallel diversifications of major clades also may have facilitated the rich diversity in East Asian Vitis.","PeriodicalId":17087,"journal":{"name":"Journal of Systematics and Evolution","volume":"61 2","pages":"273-283"},"PeriodicalIF":0.0,"publicationDate":"2022-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50141239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
