Summary: In this study, the complete FibH gene sequences of 286 silkworms were extracted from the silkworm pan-genome. The study characterized the FibH variation during domestication and breeding, established a silkworm pedigree based on the FibH gene sequence, and investigated the relationship between FibH gene cis-regulatory elements and silk yield. The findings provide insights into FibH variations and guidance for silkworm breeding.

Summary: We reported the first mitochondrial genome of Taraxacum mongolicum, in which five pairs of repetitive sequences were validated to mediate recombination, resulting in multiple conformations of the genome. This genome can provide crucial information for molecular breeding of T. mongolicum and serve as a reference genome for other species of the genus Taraxacum.

Summary: In this study, the mitochondrial genome of the short-globose cactus Mammillaria huitzilopochtli was assembled and its gene content was compared to other angiosperm species. The results suggest that the total size of mitochondrial DNA in angiosperms increases primarily through the lengthening of non-coding sequences rather than an increase in coding genes.

Summary: In this study, the complete mitochondrial genome of Tetanops sintenisi was sequenced and compared with other Diptera species. The mitogenome of T. sintenisi was found to be 15,763 bp in length and contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a non-coding A + T-rich region. Phylogenetic analysis based on the mitogenome sequence confirmed the close relationship between T. sintenisi and the Tephritidae family.

Summary: This study sequenced, assembled, and compared the complete mitogenome of Turbinellus floccosus with other basidiomycete mitogenomes, revealing unique gene arrangement and a correlation between intron number and mitochondrial genome size in Basidiomycota. The results also showed intron position preferences and evolution in Basidiomycota, as well as the effectiveness of mitochondrial genes as molecular markers for phylogeny of basidiomycetes. It contributed to understanding the intron origin and evolution in Basidiomycota, particularly in the family Gomphaceae.

Summary: Based on ostracode assemblages and shell trace elements, a 4.9-m profile in Changmu County, western Tibet, provides a continuous climate record from the Late Pleistocene to mid-Holocene. The study identifies six distinct climate change zones based on U-Th dating, indicating a transition from extremely cold to gradually warming temperatures. The paleolake (Changmu Co.) experienced fluctuations in size and water levels, reflecting variations in runoff water and a shift from a humid to a drought environment. The changes in paleoclimate in Changmu Co. corresponded well with the Westerlies-dominated Central Asia, suggesting the influence of Westerlies circulation on the climate of this region.

Summary: The study reveals the presence of ancient East Asian ancestry in southern China's Guangxi region, as well as a history of admixture with deep Asian ancestry related to Southeast Asia and local ancestry. Historical populations in Guangxi dating back to 1,500 to 500 years ago are closely related to Tai-Kadai and Hmong-Mien speakers, indicating interactions between East and Southeast Asia.

Summary: In this study, the mitochondrial genome of the Chinese medicinal plant Gelsemium elegans was sequenced, assembled, and annotated. The genome consisted of two circular chromosomes with a total length of 406,009 bp, containing 33 protein-coding genes, 15 tRNA genes, and three rRNA genes. The genome also exhibited repeat sequences, SSRs, and potential RNA editing sites. This research provides crucial insights into the understanding and utilization of G. elegans, particularly for further breeding and evolutionary analysis.

Summary: In this study, the complete mitochondrial genome of Scutellaria tsinyunensis was assembled, revealing repeat-mediated recombination resulting in two conformations. Gene migration between plastome and mitochondrial genome was observed in S. tsinyunensis, with some genes undergoing strong selection during evolution. This work provides valuable information for molecular breeding and establishes a reference genome for important medicinal plants in the genus Scutellaria.

Summary: This study presents the characterization of the complete mitochondrial genome of Ophioglossum vulgatum, a fern with medicinal and scientific value. The genome is a circular molecule of 369,673 bp in length with dispersed repetitive sequences. Phylogenetic analysis of both mitochondrial and chloroplast genomes reveals similar topologies, although there are subtle differences at certain nodes. The study highlights the need for further resolution of higher taxonomic-level phylogenetic relationships among ferns.
