Simultaneous Detection of Gene Expression of insects, nematode and bacterial specific genes to monitor the infection.

ABSTRACT: In this study, NanoString technology gene expression quantification platform was used to study the expression of toxin genes causing infections from Bacteria (Photorhabdus and Xenorhabdus), Nematode (H.indica, S.riobrave , S.carpocapsae) specific genes for detection and Immune related genes from the infected insects (Spodoptera frugiperda and Galleria mellonella). The study revealed the expression of different immune related genes from the infected insects (Spodoptera frugiperda and Galleria mellonella) and helped in understanding the trend of expression of gene in the samples from the healthy condition to the death stage. Variations in gene expression were seen as per the expectation.

Multiple Evolutionary Pathways to Host Adaptation in the Fall Armyworm

Project description:During the over 300 million years of co-evolution between herbivorous insects and their host plants, a dynamic equilibrium of evolutionary arms race has been established. However, the co-adaptation between insects and their host plants is a complex process, often driven by multiple evolutionary mechanisms. We found that various lepidopteran pests that use maize as a host exhibit differential adaptation to the plant secondary metabolites, benzoxazinoids (BXs). Notably, the Spodoptera genus, including Spodoptera frugiperda (fall armyworm) and Spodoptera litura (cotton leafworm), demonstrate greater tolerance to BXs compared to other insects. Through comparative transcriptomic analysis of the midgut, we identified four candidate genes potentially involved in BXs detoxification in S. frugiperda. Subsequently, we confirmed two UGT genes, Sfru33T10 and Sfru33F32, as key players in BXs detoxification using CRISPR/Cas9 gene-editing technology. Phylogenetic analysis revealed that Sfru33T10 evolved independently within the Noctuidae family and is involved in the glycosylation of HDMBOA, while Sfru33F32 evolved independently within the Spodoptera genus and functions as a key detoxification enzyme responsible for the glycosylation of both DIMBOA and HMBOA. Our study demonstrates that the UGT gene family plays a crucial role in the adaptation of noctuid insects to maize, with multiple independent evolutionary events within the Noctuidae family and the Spodoptera genus contributing significantly to host adaptation.

Transcriptionnal analysis of a Photorhabdus luminescens TT01 variant, named VAR*, which is a colonial and phenotypic variant displaying delayed pathogenicity in the insect, Spodoptera littoralis.

Project description:Photorhabdus luminescens lives in a mutualistic association with entomopathogenic nematodes and is pathogenic for insects. Variants of Photorhabdus frequently arise. VAR* is a colonial and phenotypic variant displaying delayed pathogenicity in the insect, Spodoptera littoralis. In this study, we evaluated the role of transcriptomic modulation in determining the phenotypic variation and delayed pathogenicity of VAR* with respect to the corresponding wild-type form, TT01alpha. A P. luminescens microarray was used to determine changes in transcript profiles in the exponential and stationary phase growth phase of VAR* and TT01alpha grown in LB broth.

RNA-seq of three Spodoptera frugiperda tissues (Midgut, Fat body, Hemocytes), at 2 time-points (8h and 15h) after infestation by entomopathogenic nematodes Steinernema carpocapsae/Xenorhabdus nematophila

Project description:Nematodes such as Steinernema carpocapsae are used as organic pesticides because of their ability to prey on live insects. They do so thanks to their symbiotic bacteria, that they release within the hemocoel of insects. In this study we wanted to study how Spodoptera frugiperda, a Lepidoptera pest of crops becoming invasive around the world, defend themselves against the nematodes. We infested S. frugiperda larvae with nematodes and dissected three tissues: the midgut, the fat body and the hemocytes at two time-points: 8 h and 15 h after infestation. We performed single-end RNA-seq on these samples to study the tissue specificity of S. fru response, as well as its dynamic.

Transcriptome-wide analysis of N6-methyladenosine modification in the embryos of Spodoptera frugiperda

Project description:N6-methyladenosine RNA (m6A) is the most abundant modification of messenger RNA (mRNA), which has been demonstrated in regulating various post-transcriptional processes and playing key roles in sex determination, neuronal functions, and embryonic development in Drosophila and mice. However, the methylation profile and relevant functions in other insects remain largely unknown. Here, we analyzed transcriptome-wide profile of m6A modification in the embryonic development of a destructive agricultural pest Spodoptera frugiperda. Our study showed that differentially expressed m6A peak-modified genes were enriched in cell and organ development between the 2 h and 24 embryos. Our study reveals that RNA m6A epigenetic regulation in the embryonic development of S. frugiperda, and provides new insight for the embryonic development of insects.

Antibiotics exposure impacts the gut microbiota and influences energy and metabolic homeostasis in Spodoptera frugiperda

Project description:Insect gut microbiota plays important roles in acquiring nutrition, preventing pathogens infection, immune responses, and communicating with the environment. Gut microbiota can be affected by some external factors such as foods, temperature, and antibiotics. Spodoptera frugiperda (Lepidoptera: Noctuidae) is an important destructive pest of grain crops all over the world. The function of gut microbiota in S. frugiperda remains to be investigated. In this study, we fed the S. frugiperda with the antibiotic mixture (penicillin, gentamicin, rifampicin, and streptomycin) to perturb the gut microbiota, and further examined the effect of dysbiosis in gut microbiota on the gene expression of S. frugiperda by RNA sequencing. We found the composition and diversity of the gut bacterial community were changed in S. frugiperda after antibiotics treatmen, and the expression of genes related to energy and metabolic process were affected after antibiotics exposure in S. frugiperda. Our work will help understand the role of gut microbiota in insects.

De novo sequencing of transcriptome of Sf9 cells after Bm-15 overexpression and repression

Project description:Small nucleolar RNAs (snoRNA) function in guiding 2'-O-methylation and pseudouridylation of ribosomal RNAs. But we found that knock down of a C/D box snoRNA, Bm-15, can induce apoptosis of insect Spodoptera frugiperda Sf9 cells. For the genome sequence of Spodoptera frugiperda is incomplete, here with the de novo sequencing method, transcriptome of Spodoptera frugiperda cell line Sf9 were sequenced after being transfected with overexpression vector and repression probes of snoRNA Bm-15. Results showed that 21 apoptosis-related genes were up-regulated upon Bm-15 inhibition and down-regulated with Bm-15 overexpression.
