FAH genes located in the same subgroup presented similar gene structures and a consistent distribution of conserved motifs through the analysis of evolutionary trees, gene structures, and conserved motifs. Chromosomal localization analysis of the FAH gene family revealed that it has undergone chromosomal segment duplication events. Analysis of cis-acting elements suggested that the FAH gene may be involved in regulating biotic and abiotic stresses, plant growth and development, signaling pathways, and other physiological processes. The RT‒qPCR results revealed significant differences in the expression levels of FAH gene family members under salt stress conditions compared with those in the control group.

This study introduces TransGeneSelector, the first deep learning framework specifically designed for mining key genes from small transcriptomic datasets. By integrating a Wasserstein Generative Adversarial Network with Gradient Penalty (WGAN-GP) for sample generation and a Transformer-based network for classification, TransGeneSelector efficiently addresses the challenges of small-sample transcriptomic data, capturing both global gene regulatory interactions and specific biological processes.

Moreover, Shapley Additive Explanations (SHAP) analysis and gene regulatory network construction revealed that TransGeneSelector effectively identified genes that appear to have upstream regulatory functions based on our analyses, enriching them in multiple key pathways which are critical for seed germination and heat stress response. RT-qPCR validation further confirmed the model's gene selection accuracy, demonstrating consistent expression patterns across varying germination conditions.

Biting midges of the genus Culicoides are vectors of arboviruses that significantly affect livestock worldwide. Culicoides stellifer is a suspected vector with a wide range distribution in North America, for which cryptic diversity has been described.</p><p><strong>Results: </strong>With just one specimen of C. stellifer, we assembled and annotated the nuclear and mitochondrial genome using the ultra-low input DNA PacBio protocol. The genome assembly is 119 Mb in length with a contig N50 value of 479.3 kb, contains 11% repeat sequences and 18,895 annotated protein-coding genes. To further elucidate the role of this species as a vector, we provide genomic evidence of a non-retroviral endogenous viral element integrated into the genome that corresponds to rhabdovirus nucleocapsid proteins, the same family as the vesicular stomatitis virus.</p><p><strong>Conclusions: </strong>This genomic information will pave the way for future investigations into this species's putative vector role. We also demonstrate the practicability of completing genomic studies in small dipterans using single specimens preserved in ethanol as well as introduce a workflow for data analysis that considers the challenges of insect genome assembly.</p>","PeriodicalId":9030,"journal":{"name":"BMC Genomics","volume":"26 1","pages":"247"},"PeriodicalIF":3.5,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11907880/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143633408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
