In this study, we assembled the mitochondrial genome of P. fluitans representing the first mitochondrial genome report of the Phyllanthaceae family. The mitogenome comprises two circular chromosomes spanning 230,785 bp (chromosome 1) and 143,421 bp (chromosome 2), collectively harboring 32 protein-coding genes (PCGs), 25 tRNA genes, four rRNA genes, and one pseudogene. Structural analyses identified 118 simple sequence repeats (SSRs), 18 tandem repeats, and 191 dispersed repeats distributed throughout the mitochondrial genome. RNA editing prediction revealed 394 putative editing sites, with notable enrichment in NADH dehydrogenase genes. Critical modifications included start codon conversion in atp6 (ACG → AUG) and stop codon alterations in ccmFc (CGA → UGA) and rpl16 (UAG → UAA). Comparative genomic analyses detected 50 chloroplast-derived DNA fragments, constituting 6.0% of the mitogenome, indicative of historical plastid-to-mitochondrion transfer events. Codon usage bias analysis demonstrated phenylalanine (Phe) as the most frequently encoded amino acid, with selection pressure identified as the predominant driver of codon usage patterns. Phylogenetic reconstruction employing 22 conserved PCGs resolved intra-ordinal relationships among eight Malpighiales families, revealing Phyllanthaceae sister to Salicaceae with robust nodal support. This study advances the utilization of mitochondrial genomes for elucidating phylogenetic relationships within Phyllanthus while providing essential genomic resources for future comparative mitogenomic investigations in Phyllanthaceae. The structural complexity revealed through repeat analyses and RNA editing patterns offers novel insights into plant mitochondrial genome evolution.","PeriodicalId":55121,"journal":{"name":"Genetica","volume":"153 1","pages":"25"},"PeriodicalIF":1.3,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144644189","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 Q-type ZFP, a plant-specific subfamily, are particularly important in responding to abiotic stresses. Wheat is a crucial staple crop in world, with drought significantly affecting its yield and quality. Developing drought-resistant varieties is one of the most cost-effective strategies to mitigate drought stress in wheat. Here, we identified 772 non-redundant members of the Q-type ZFP genes family in Triticeae. Among them, 267 genes were found in common wheat, 56 in wild emmer wheat, 157 in spelt wheat, 154 in durum wheat, 56 in Triticum urart, and 82 in Aegilops tauschii. The phylogenetic tree shows that the Q-type ZFP genes family can be divided into five groups. The Q-type ZFPs family are mainly regulated by MYB, MYC, and WRKY transcription factors. Moreover, there are a large number of drought stress and ABA-related cis-acting elements in the promoter region. We studied their gene structures and found that most genes have a single exon. In this study, we identified 76 tandemly duplicated gene pairs across the six species. A total of 3,445 collinear gene pairs were found, with 1,877 pairs in wheat. Furthermore, most collinear gene pairs have Ka/Ks values less than 1. Comparative analysis of multiple physiological indices, including relative coleoptile length and CAT activity, revealed that common wheat cultivars JM6425 and JM4293 exhibited stronger drought tolerance compared to JM4258 and JM5787.

However, a comprehensive analysis of the bHLH family in sand rice has not yet been conducted. In this study, a total of 69 bHLH genes (AsbHLHs) were identified and classified into 18 subfamilies based on phylogenetic analysis. Their physicochemical properties, bHLH domains, conserved motifs, and gene structures were further examined. Most AsbHLHs within the same subfamily shared similar characteristics. cis-Regulatory elements (CREs) and Gene Ontology (GO) analyses suggested that AsbHLHs are involved in plant development, hormonal signaling, and stress responses. Transcriptomic analysis revealed tissue- and stress-responsive-specific expression profiles of AsbHLHs. qRT-PCR validation confirmed the expression of 69 AsbHLHs across different tissues and 17 genes under salt and drought stress, with AsbHLH7, 10, 20, 22, 32, 46, 53, 59, 64, 65, 68, and 69 proposed as potential regulators in stress response. Protein-protein interaction network predications showed that these proteins may potentially form complexes, which could participate in stress-related biological processes.

Therefore, in this study, the mitochondrial genomes (mitogenomes) of five black fly species‒Simulium bidentatum, S. siripoomense, S. fenestratum, S. chamlongi, S. quinquestriatum‒were sequenced using next-generation sequencing. We conducted a comprehensive comparative analysis of these mitogenomes focusing on sequence length, A + T content, A/T bias, A + T- rich regions, overlapping and intergenic regions, nucleotide composition, relative synonymous codon usage, and the non-synonymous/synonymous substitution ratio (Ka/Ks). Additionally, we analyzed the phylogenetic implications in combination with the Simuliidae and Nematocera species available in GenBank. The mitogenomes ranged from 15,739 to 16,451 base pairs (bp); each contained 37 genes, with no gene rearrangements. The tRNASer (Ser1) lacks the dihydrouridine arm. Selection pressure analysis of 13 PCGs in 45 Nematocera mitogenomes revealed that nd2, nd5, nd4 l, and nd1 had Ka/Ks ratios greater than 1, indicating higher rates of non-synonymous substitutions. In contrast, cox1 showed the lowest Ka/Ks values, indicating strong purifying selection. Phylogenetic analyses supported the monophyly of each subgenus within Simulium, but revealed different subgeneric relationships compared to previous studies. We also observed that different samples can yield different phylogenetic results for higher level relationships within Culicomorpha.

Benth., a widely distributed tropical tree. The complete cp. genome was assembled de novo using NOVOPlasty and annotated with GeSeq and Geneious Prime. Repeat elements and codon usage analyses were analyzed using REPuter, Phobos, and Geneious Prime. Comparative genomic analyses included structural comparisons, IR expansion/contraction, and nucleotide divergence. Phylogenetic relationships were inferred from protein-coding genes using IQ-TREE and MrBayes, with divergence times estimated via BEAST2.

Regarding this environmental change, Drosophila subobscura stands out as a useful model species due to its rich inversion polymorphism covering the whole karyotype. The main aims of this research were to analyze the differentiation of this polymorphism in Jastrebac Mt. (Serbia) depending on the different habitats (beech and oak forests) and over time. These latter changes were studied in relation to climatic variables (mean, minimum and maximum temperatures, humidity and rainfall). Microdifferentiation was observed between beech and oak forests, mainly for the A and O chromosomes. However, the changes over time turned out to be larger than those due to habitat. In Jastrebac Mt., temperatures increased over time, with this increase being significant for mean and minimum one. The Multidimensional Scaling analysis showed a relation between chromosomal inversions and temperatures (mainly minimum) in Jastrebac Mt. and other Serbian populations of D. subobscura. In beech forest of Jastrebac Mt., the Chromosomal Thermal Index increased over time from 1990 to 1994, but showing a possible stabilization in 2023.
