Abstract

Tetrapedia diversipes is a Neotropical solitary bee commonly found in trap-nests, known for its morphological adaptations for floral oil collection and prepupal diapause during the cold and dry season. Here, we present the genome assembly of T. diversipes (332 Mbp), comprising 2,575 scaffolds, with 15,028 predicted protein-coding genes. Repetitive elements constitute 38.68% of the genome, notably Class II transposable elements. An investigation into lateral gene transfers identified a low frequency (0.037%) of nuclear copies of mitochondrial DNA and 18 candidate regions from bacterial origins. Furthermore, the annotation of 3 scaffolds reveals the presence of the Wolbachia endosymbiont genome, confirming the infection by 2 strains in T. diversipes populations. This genome contributes valuable insights into Neotropical bee genomics, offering a resource for comparative studies and enhancing our understanding of the molecular basis of solitary bee adaptations and interactions.

孤蜂四足群的基因组研究（膜翅目，蜂科）。

四足蜂（Tetrapedia diverpes）是一种新热带独居蜜蜂，常见于陷阱巢中，以其在寒冷和干燥季节的花油收集和蛹前滞育的形态适应而闻名。在这里，我们展示了T. diversified （332 Mbp）的基因组组装，包括2,575个支架，其中有15,028个预测的蛋白质编码基因。重复元件占整个基因组的38.68%，尤其是II类转座元件。对横向基因转移的调查发现，线粒体DNA的核拷贝频率较低（0.037%），有18个候选区域来自细菌起源。此外，3个支架的注释显示存在沃尔巴克氏体内共生体基因组，证实了2株菌株在T. diverpes群体中的感染。该基因组为新热带蜜蜂基因组学提供了有价值的见解，为比较研究提供了资源，并增强了我们对独居蜜蜂适应和相互作用的分子基础的理解。

期刊介绍： G3: Genes, Genomes, Genetics provides a forum for the publication of high‐quality foundational research, particularly research that generates useful genetic and genomic information such as genome maps, single gene studies, genome‐wide association and QTL studies, as well as genome reports, mutant screens, and advances in methods and technology. The Editorial Board of G3 believes that rapid dissemination of these data is the necessary foundation for analysis that leads to mechanistic insights. G3, published by the Genetics Society of America, meets the critical and growing need of the genetics community for rapid review and publication of important results in all areas of genetics. G3 offers the opportunity to publish the puzzling finding or to present unpublished results that may not have been submitted for review and publication due to a perceived lack of a potential high-impact finding. G3 has earned the DOAJ Seal, which is a mark of certification for open access journals, awarded by DOAJ to journals that achieve a high level of openness, adhere to Best Practice and high publishing standards.
