<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Microorganisms play a pivotal role in modulating both the synthesis and perception of pheromones in insects, exerting profound influences on their behavior, physiology, and population dynamics. Through diverse mechanisms, including metabolic regulation, gene expression modulation, and intervention in signaling pathways, microorganisms intricately regulate the production and perception of pheromones in their insect hosts. This regulation not only enhances insect adaptability but may also instigate intraspecific competition and resource allocation conflicts. This review synthesizes recent advancements in understanding microbial influences on insect pheromone biosynthesis and sensory perception, providing an in-depth analysis of the underlying mechanisms. Furthermore, it explores the evolutionary implications of these regulatory mechanisms within insect-microbe symbiotic systems, aiming to elucidate the complex interplay between these organisms and to offer novel insights and research directions for future investigations in this field.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The hindgut of termites is enlarged and specialized, providing a habitat for intestinal microorganisms. Except for termites belonging to the Termitidae family, all other termite species harbor protists in their guts. The protists in the termite gut belong to the Parabasalia phylum and Preaxostyla phylum Oxymonadida order. The gut protists of termites coexist with various bacteria, exhibiting a coevolutionary relationship. Termites, protists, and bacteria form a triplex symbiotic system. The distribution of gut protists within the intestine demonstrates heterogeneity. The transmission mechanism of gut protists not only ensures the stability of the gut microbiota but also facilitates the continuous evolution of the gut microbiota colonies in termites. Additionally, the abundance of gut protists in termites is influenced by various factors, including termite caste and diet. Gut protists are crucial for termites as they contribute to the decomposition of lignocellulose, nitrogen fixation, participation in intestinal gas metabolism, and the provision of nutrients to termites. This article provides a comprehensive review of the classification of gut protists, symbiotic bacteria of protists, spatial distribution, transmission, and functions of protists, aiming to offer a valuable reference for future research.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Insects, the most diverse group of organisms on earth, harbor a rich array of gut microbes. These gut microbiota exert direct and indirect influences on their hosts, playing pivotal roles in critical physiological processes including growth and development, reproduction, nutrient metabolism, immune defense, plant-insect interactions, and detoxification of harmful substances. Lepidoptera, the second-largest order within the class Insecta, exhibit remarkable diversity in their gut microbiota both within and across species. Integration of molecular biology techniques into gut microbiota research has stimulated growing interest worldwide in exploring the gut microbiota of lepidopterans. This review provides a comprehensive assessment of the known diversity, transmission pathways, driving factors, and biological effects of lepidopteran gut microbes, and describes mechanisms underlying the interactions between lepidopteran insects and their gut microbiota, establishing a theoretical foundation for pest management strategies and the development and utilization of lepidopteran gut microbiota, thereby contributing to sustainable agricultural and economic development.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The gut microbiota of honey bees consists of a specialized group of bacteria that are essential for host nutrition metabolism, immune regulation, and detoxification. In this study, a bacterial strain designated G0441 was isolated from the intestinal tract of worker bees of Apis cerana cerana. This strain was subsequently identified and under genome analysis. The colonies of G0441 exhibited a circular morphology, measuring approximately 1 mm in diameter, with a smooth and translucent surface. The G0441 grew under strict anaerobic conditions. The result by 16S rRNA gene sequence analysis showed that G0441 strain belonged to γ-Proteobacteria, the family Orbaceae with the closest relatives being members of the Gilliamella genus. The genome of G0441 was 2.6 Mb in size and has a total GC content ratio of 35%. It encoded a total of 2 350 genes, including 2 299 protein-coding genes, which accounted for 85% of the genome's total length. Function clarified annotation of the protein-coding genes using the Cluster of Orthologous Groups (COG) database showed that the following function clarifications were enriched significantly, including amino acid transport and metabolism, carbohydrate transport and metabolism, translation-ribosomal structure and biogenesis, transcription, replication-recombination-repair, and cell wall/membrane/envelope biogenesis. Additionally, genome annotation of G0441 identified 159 virulence factors, 77 antibiotic resistance genes, 22 carbohydrate-active enzymes, 255 transporter proteins, 565 transmembrane protein genes, 201 signal peptide protein genes, and multiple lipoproteins genes. Pan-genome analysis showed that six closely related strains revealed 145 shared genes and 7 190 specific genes, with G0441 containing 221 specific genes. Phylogenetic analysis, based on both core single-copy genes and whole-genome SNPs, consistently demonstrated that G0441 was most closely related to the Gilliamella sp. ESL0441 strain. This study successfully isolated and identified a strain of Gilliamella bacteria, designated as Gilliamella sp. G0441, from gut microbiota of A. cerana. The genomic data obtained in this study provide a foundation for further investigation of Gilliamella sp. G0441 related function.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Cellulosic biomass is the most widely distributed renewable resource on earth, and the screening of efficient cellulose-degrading bacterial strains is of great significance for the development and utilization of cellulosic biomass resources. We screened 58 cellulose-degrading bacteria from the 3rd instar larvae of Allomyrina dichotoma by Congo red staining method, and selected the strain with larger ratio of transparent circle diameter to strain diameter for enzyme activity determination. Bacterial strain M24 was the strongest cellulase-producing strain by combining the results of Congo red staining method and enzyme activity determination. The filter paper enzyme, endoglucosidase, exoglucosidase and β-glucosidase with high activities of bacterial strain M24 were 13.14 U/mL, 45.67 U/mL, 18.29 U/mL and 36.30 U/mL, respectively. It was identified as Bacillus velezensis by comparison and analysis of 16S rDNA sequence. The whole genome sequence of the strain was obtained by genome ONT sequencing technology, which was 4 290 258 bp in length, with a total of 15 cellulase-related genes annotated, including 4 endo-β-1,4 glucanase genes (EC 3.2.1.4), 9 β-glucosidase (EC 3.2.1.91)-related genes, and 2 exo β-1,4 glucanase (EC 3.2.1.91)-related genes. This result provides an important theoretical basis and test material for constructing cellulose degradation engineering bacteria.]]></description>
