The plastome analysis revealed a length of 153,383 bp, showing variation from conspecific taxa in China. Its standard structure comprises two IR regions (18,336 bp IRa and 18,336 bp IRb), an LSC region of 97,944 bp, and an SSC region of 18,767 bp, with a GC content of 37.63%. Non-coding regions showed higher mutation susceptibility, with Pi values from 0.006 to 0.107. An AT-rich codon bias was consistent across all 18 Hydrocotyle species. Nucleotide composition and GC% in coding sequences differed among the species. The codon preference in Hydrocotyle is shaped by multiple factors, with natural selection being the primary influence, as indicated by the ENC-plot, PR2-plot, and Neutrality-plot. Codon usage patterns varied, with RSCU values from 0 to 2.23. Codons ending in A or U had RSCU > 1, while those ending in C or G had RSCU < 1. GC2 content surpassed GC3 and GC1 in most genes. The phylogenetic analysis placed H. himalaica, sourced from Kanglung, Bhutan, within the monophyly of the Hydrocotyloideae subfamily. However, the species showed weaker bootstrap support (BS < 50) with H. javanica and H. hookeri subsp., a deviation from a prior report on the same species from Jiangkou, Guizhou, China. This analysis highlighted the genomic characteristics and evolutionary relationships of H. himalaica from Bhutan, underscoring the need for a comprehensive phylogenetic, ecological, and botanical characterization to confirm intra-specific variation within Hydrocotyle species.","PeriodicalId":55121,"journal":{"name":"Genetica","volume":" ","pages":"199-209"},"PeriodicalIF":1.3,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142332695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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, the weighted gene co-expression network analysis (WGCNA) strategy was used to integrate multiple data in leaf tissue of Populus species under different sample treatments. The gene co-expression networks were constructed and functional modules were identified by selecting the suitable soft threshold power β in the procedure of WGCNA. The identified hub genes and gene modules were annotated by agriGO, NetAffx Analysis Center, The Plant Genome Integrative Explorer (PlantGenIE) and other annotation tools. The annotation results have displayed that the highly correlated modules and hub genes are involved in the important biological processes or pathways related to module traits. The efficiency of the WGCNA strategy can generate comprehensive understanding of gene module-traits associations in leaf tissue, which will provide novel insight into the genetic mechanism of Populus species.","PeriodicalId":55121,"journal":{"name":"Genetica","volume":"153 1","pages":"5"},"PeriodicalIF":1.3,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142734777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, numerous studies have employed this method to encompass species checklists of different areas, assessment of cryptic diversity, biodiversity monitoring, and other applications. Furthermore, most of the success of COI DNA barcoding relies on a comprehensive database (BOLD Systems) that holds sequences and detailed records of millions of species and applies a system (BIN) that clusters short DNA barcodes to generate OTUs. Besides COI, the 16S rDNA has proven to be suitable for the molecular identification of several taxa, and the combination of both markers could be advantageous in investigating species composition in the Neotropics. The family Paralichthyidae comprises over 60 flatfish species. Most of them inhabit tropical areas and remain understudied. Here, we evaluated the diversity of Paralichthyidae species along the Brazilian coast through COI and 16S DNA barcodes. Combining our dataset with BOLD (COI) and GenBank (16S) public records, we conducted tree-based and genetic distance analyses along with BIN-based and species delimitation methods. Our results were consistent for both markers, and we identified eight species of paralichthyids among our samples with high confidence. Interestingly, our analyses indicate several cases where public records assigned to the same species might be sequences from multiple species. Therefore, we provide new records and occurrences and explore important issues regarding misidentification and putative cryptic diversity for several species.","PeriodicalId":55121,"journal":{"name":"Genetica","volume":"153 1","pages":"4"},"PeriodicalIF":1.3,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142717965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of detoxifying enzymes glutathione S-transferase (GST) in T. castaneum makes it resistant to a variety of insecticides. However, whether GST is involved in regulating the sensitivity of eucalyptol by T. castaneum is not well understood. In our previous study, a glutathione S-transferase, TcGSTu1, was significantly up-regulated in RNA sequencing data when T. castaneum was exposed to eucalyptol. Therefore, in this study, the role of TcGSTu1 in the regulating the sensitivity of T. castaneum to eucalyptol was studied. The enzyme activities of GST and the transcription levels of TcGSTu1 were significantly increased following stimulation with eucalyptol. When using RNA interference technology knockdown TcGSTu1 heightens the sensitivity of T. castaneum to eucalyptol, demonstrating a link between TcGSTu1 and eucalyptol detoxification metabolism. Furthermore, TcGSTu1 is expressed in all developmental stages of T. castaneum, with higher expression levels observed particularly in the late egg stage. There was significant expression of TcGSTu1 in various tissues of different organisms, including larval head, fat body, and adult head. This observation indicated a possible connection between high TcGSTu1 expression and eucalyptol detoxification.

In this study, we identified 32 members of the OsXIP gene family and analyzed their physicochemical properties, chromosomal localization, gene structure, protein structure, expression profiles, and interaction networks. Our results indicated that OsXIP genes exhibit an uneven distribution across eight rice chromosomes. These genes generally feature a low number of introns or are intronless, all family members, except for OsXIP20, contain two highly conserved motifs, namely Motif 8 and Motif 9. In addition, it is worth noting that the promoter regions of OsXIP gene family members feature a widespread presence of abscisic acid response elements (ABRE) and gibberellin response elements (GARE-motif and TATC-box). Quantitative Real-time PCR (qRT-PCR) analysis unveiled that the expression of OsXIP genes exhibited higher levels in leaves and roots, with considerable variation in the expression of each gene in these tissues both prior to and following treatments with abscisic acid (ABA) and gibberellin (GA3). Protein interaction studies and microRNA (miRNA) target prediction showed that OsXIP engages with key elements within the hormone-responsive and drought signaling pathways. The qRT-PCR suggested osa-miR2927 as a potential key regulator in the rice responding to drought stress, functioning as tissue-specific and temporally regulation.
