Abstract
Introduction Traditional chemical control methods pose a damaging effect on farmland ecology, and their long-term use has led to the development of pest resistance. Methods Here, we analyzed the correlations and differences in the microbiome present in the plant and soil of sugarcane cultivars exhibiting different insect resistance to investigate the role played by microbiome in crop insect resistance. We evaluated the microbiome of stems, topsoil, rhizosphere soil, and striped borers obtained from infested stems, as well as soil chemical parameters. Results and Discussion Results showed that microbiome diversity was higher in stems of insect-resistant plants, and contrast, lower in the soil of resistant plants, with fungi being more pronounced than bacteria. The microbiome in plant stems was almost entirely derived from the soil. The microbiome of insect-susceptible plants and surrounding soil tended to change towards that of insect-resistant plants after insect damage. Insects' microbiome was mainly derived from plant stems and partly from the soil. Available potassium showed an extremely significant correlation with soil microbiome. This study validated the role played by the microbiome ecology of plant-soil-insect system in insect resistance and provided a pre-theoretical basis for crop resistance control.

[PMID: 35323589 PMCID: PMC8948783 DOI: 10.3390/insects13030291] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 03/06/2022] [Accepted: 03/11/2022] [Indexed: 02/04/2023]
Abstract
Silkworms, a model lepidopteran insect, have a very simple diet. Artificial diets as an alternative nutrient source for silkworms are gradually being developed. To understand the effects of various nutrients on the growth and development of silkworms, we studied the transcriptomic differences in the midgut and head tissues of male and female silkworms fed either fresh mulberry leaves or artificial diets. In the artificial diet group, compared with the control group (fed mulberry leaves), 923 and 619 differentially expressed genes (DEGs) were identified from the midgut, and 2969 and 3427 DEGs were identified from the head, in female and male silkworms. According to our analysis, the DEGs were mainly involved in the digestion and absorption of nutrients and silkworm innate immunity. These experimental results provide insights into the effects of different foods, such as artificial diets or fresh mulberry leaves, on silkworms.

JOURNAL OF ECONOMIC ENTOMOLOGY 2021; 114:1975-1982.

Abstract
Antheraea pernyi (Guérin-Méneville 1855) is an important resource for silk, food, and biohealth products; however, exogenous pathogens largely affect the commercial application potential of this species. Since the gut is a key organ for the digestion and absorption of nutrients as well as for immune defense, we used comparative transcriptome analysis to screen for a gut-specific molecular tool for further functional research in A. pernyi. In total, 3,331 differentially expressed genes (DEGs) were identified in the gut compared with all other pooled tissues of A. pernyi, including 1,463 upregulated genes in the gut. Among these, we further focused on a lipopolysaccharide-induced tumor necrosis factor-α factor (LITAF) gene because of its high gut-specific expression and the presence of a highly conserved SIMPLE-like domain, which is related to the immune response to pathogenic infections in many species. The cDNA sequence of ApLITAF was 447-bp long and contained a 243-bp open reading frame encoding an 80-amino acid protein. Immune challenge assays indicated that ApLITAF expression was significantly upregulated in the gut of A. pernyi naturally infected with nucleopolyhedrovirus (NPV) or fed leaves infected with the gram-negative bacterium Escherichia coli (Migula 1895) and the gram-positive bacterium Bacillus subtilis (Ehrenberg 1835). Cell transfection showed that ApLITAF localized to the lysosome. Collectively, these results suggested that ApLITAF played a role in the immune response of A. pernyi and could facilitate the future research and breeding application in this species.

Sheehan G, Margalit A, Sheehan D, Kavanagh K. Proteomic profiling of bacterial and fungal induced immune priming in Galleria mellonella larvae. JOURNAL OF INSECT PHYSIOLOGY 2021; 131:104213. [PMID: 33662378 DOI: 10.1016/j.jinsphys.2021.104213] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 02/19/2021] [Accepted: 02/24/2021] [Indexed: 06/12/2023]
Abstract
Some insects display immunological priming as a result of elevated humoral and cellular responses which give enhanced survival against subsequent infection. The humoral immune response of Galleria mellonella larvae following pre-exposure to heat killed Staphylococcus aureus or Candida albicans cells was determined by quantitative mass spectrometry in order to assess the relationship between the humoral immune response and resistance to subsequent bacterial or fungal infection. Larvae pre-exposed to heat killed S. aureus showed increased resistance to subsequent bacterial and fungal infection. Larvae displayed an increased hemocyte density (14.08 ± 2.14 × 106 larva-1 (p < 0.05) compared to the PBS injected control [10.41 ± 1.67 × 106 larva-1]) and increased abundance of antimicrobial proteins (cecropin-D-like peptide (+22.23 fold), hdd11 (+12.61 fold) and prophenol oxidase activating enzyme 3 (+5.96 fold) in response to heat killed S. aureus. Larvae pre-exposed to heat killed C. albicans cells were resistant to subsequent fungal infection but not bacterial infection and showed a reduced hemocyte density (6.01 ± 1.63 × 106 larva-1 (p < 0.01) and increased abundance of hdd11 (+32.73 fold) and moricin-like peptide C1 (+16.76 fold). While immune priming is well recognised in G. mellonella larvae the results presented here indicate distinct differences in the response of larvae following exposure to heat killed bacterial and fungal cells.
