Project description:This study was designed to identify the sRNAs in Aphis gossypii (cotton-melon aphid) during Vat-mediated resistance in teraction with melon Methods: Whole insects were collected from susceptible (Vat-) and resistant (Vat+) plants after 48 hours of feeding. Total RNA was extracted from the aphids and enriched for LMW RNA and small RNA libraries were constructed using standard protocols and deep sequenced using Illumina GAII analyzer.

Project description:The cowpea aphid, Aphis craccivora (Hemiptera: Aphididae), is one of the most destructive insect pests of cowpea, peanut, and other legumes in tropical and subtropical regions. However, there are little-known molecular mechanisms underlying the host plant specification and their interaction. Aphids secretes numerous proteins while feeding on plants to counteract plant defenses which became indispensable for its survival and growth. In this study we identified salivary proteins of cowpea aphid using LC-MS/MS.

Project description:The cotton - melon aphid Aphis gossypii is an extremely polyphagous sap feeding insect which infests more than 900 crops worldwide and posing a severe threat to farmers. The salivary proteins acts as interface between aphid and their host plant.However, the cotton aphid salivary proteome was not studied yet. Identifying the salivary proteins helps in better understanding of aphid adaptation to their host plant which aids us to search for novel plant genetic source.

Project description:Purpose: Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae) and soybean cyst nematode, Heterodera glycines Ichinohe, (SCN) are the two most economically important pests of soybean, Glycine max (L.) Merr., in the Midwest. Although the soybean aphid is an aboveground pest and SCN is a belowground pest there is evidence that concomitant infestations result in improved SCN reproduction. This study is aimed to characterize the three-way interactions among soybean, soybean aphid and SCN using demographic and genetic datasets. Results: More than 1.1 billion reads (61.4 GB) of transcriptomic data were yielded from 47 samples derived from the experiment using whole roots of G. max. The phred quality scores per base for all the samples were higher than 30. The GC content ranged from 43 to 45% and followed the normal distribution. After trimming, more than 99% of the reads were retained as the clean and good quality reads. Upon mapping these reads, we obtained high mapping rate ranging from 73.8% to 94.3%. Among the mapped reads, 67.1% to 87.6% reads were uniquely mapped. Conclusions: The comprehensive understanding of these transcriptome data would help in understanding the molecular interactions among soybean, A. glycines, and H. glycines. The use of multifaceted bioinformatics approaches could facilitate finding candidate genes and their function that might play a crucial role in various pathways for host resistance against both soybean aphids and SCN. For differential gene expression analysis, EdgeR, limma, and DEseq2 could be used. Apart from standalone tools like iDEP, Galaxy (https://usegalaxy.org), CyVerse (http://www.cyverse.org), and MeV (http://mev.tm4.org) could also be used for both analysis and visualization of RNA- seq data.

Project description:The cotton-melon aphid, Aphis gossypii Glover, is a major insect pest worldwide. Lysiphlebia japonica (Ashmead) is an obligate parasitic wasp of A. gossypii, and has the ability to regulate lipid metabolism of the cotton-melon aphid. Lipids are known to play critical roles in energy homeostasis, membrane structure, and signaling. However, the parasitoid genes that regulate fat metabolism and lipid composition in aphids are not known. 34 glycerolipids and 248 glycerophospholipids were identified in this study. We have shown that a 3-day parasitism of aphids can induce significant changes in the content and acyl chain composition of triacylglycerols (TAGs) and subspecies composition of glycerophospholipids content and acyl chains. It also upregulate the expression of several genes involved in triacylglycerol synthesis and glycerophospholipid metabolism. Pathway analysis showed that a higher expression of genes involved in the tricarboxylic acid cycle and glycolysis pathways may contribute to TAGs synthesis in parasitized aphids. Interestingly, the higher expression of genes in the sphingomyelin pathway and reduced sphingomyelin content may be related to the reproductive ability of A. gossypii. We provide a comprehensive resource describing the molecular signature of parasitized A. gossypii particularly the changes associated with the lipid metabolism and discuss the biological and ecological significance of this change.
