Abstract Gut microbiota are important in the adaptation of phytophagous insects to their plant hosts. However, interaction between gut microbiomes and pioneering populations invasive during new hosts, particularly initial phases invasion, has been less studied. We studied contribution microbiome host globally recognized pest, Hyphantria cunea, as it expands its range into southern China. The population H. cunea shows effective Metasequoia glyptostroboides exhibits greater larval survival on than original population. Genome resequencing revealed no significant differences functions related two populations. compatibility M. a correlation abundance several bacteria genera (Bacteroides, Blautia, Coprococcus) survival. Transplanting from northern enhanced adaptability latter previously unsuitable glyptostroboides. This research provides evidence that can enhance pests hosts enable more rapid habitats.

Insects adjust their adaptive capacity to biotic and abiotic stresses by collecting utilizing microorganisms from the environment diet. are ubiquitous in almost all ecosystems contribute significantly ecosystem stability (Schowalter et al. 2018; Crespo-Pérez 2020; Sun 2023; Sveen 2023). Due climate change human activities, insects constantly exposed emerging stresses, compelling them develop physiological, behavioral, morphological adaptations withstand these challenges (Behmer 2009; Sheikh 2017; Xiong 2022; Bai While genomic evolution natural selection stable strategies for accumulating changes, processes often take thousands or even millions of years (Lamichhaney 2015; Lamichhaney 2016; Nuismer 2022), making it challenging adapt swiftly stresses. There long-term dynamic interactions between associated microorganisms, which readily incorporated into insect bodies onto body surfaces extensively involved various physiological activities host (Douglas Hosokawa & Fukatsu 2020). Generally, sites on inhabited diverse leading extensive competition among them. Thus, can theoretically exploit enhance fitness adaptability. Indeed, recent studies have discovered similar cases, providing new insights functions insect-associated adaption (Fig. 1). Under normal circumstances, gut-beneficial microbes outcompete harmful ones perform that aid host, including breaking down complex nutrients, fostering growth development, detoxifying compounds (Tellez 2006; Kikuchi 2012; Jordan Tomberlin 2021; Zhang 2024c). For instance, changes gut microbial composition Bactrocera dorsalis affect metabolism transcriptional regulation, thereby promoting (Wang They also shape gut-associated lymphoid tissue assembly, educate immune system, impact intestinal mucosal barrier integrity Xu 2018), insect's ability detoxify plant-released defense chemicals (Pincebourde Salem Wang Several derived silkworm guts exhibit probiotic potential resistance diseases toxins, insecticides (Jordan Liang 2022). However, as mentioned earlier, survival is changing, especially invasive whose living environments undergo drastic during invasion process. Some respond along with may rapidly increase abundance host. Recently, found Hyphantria cunea recruit (Bacteroides, Blautia, Coprococcus) help plant, Metasequoia glyptostroboides, its expansion range southern China (Zhang 2024a).

Journal of genetics and genomics/Journal of Genetics and Genomics, Journal Year: 2024, Volume and Issue: 51(10), P. 1121 - 1134

Published: June 29, 2024

Heterosis has been widely utilized in agricultural production. Despite over a century of extensive research, the underlying mechanisms heterosis remain elusive. Most hypotheses and research have focused on genetic basis heterosis. However, potential role gut microbiota largely ignored. Here, we carefully design crossbreeding experiment with two distinct broiler breeds conduct 16S rRNA amplicon transcriptome sequencing to investigate synergistic host genes driving We find that breast muscle weight hybrids exhibits high heterosis, 6.28% higher than mid-parent value. A notable difference is observed composition function cecal between their parents. Over 90% differentially colonized expressed exhibit nonadditive patterns. Integrative analyses uncover associations microbiota, including connection expression cellular signaling pathways metabolism-related abundance Odoribacter, Oscillibacter, Alistipes hybrids. Moreover, abundances these are related better meat yield. In summary, findings highlight importance serving as crucial factors modulate chickens.

Abstract BACKGROUND The tomato russet mite (TRM), Aculops lycopersici , is a strictly herbivorous and economically significant pest that infests Solanaceae plants, but its host suitability varies, showing high performance on tomatoes. Although symbiotic bacteria have been suggested to play crucial roles in the adaptation of herbivores, their effects TRM remain unclear. RESULTS In this study, using next generation high‐throughput sequencing bacterial 16S rRNA data, we identified diversity community composition feeding tomato, eggplant, chili.
