Expression of small RNA in Aphis gossypii and its potential role in the resistance interaction with melon

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.

Proteomic analysis of saliva and salivary gland of Aphis gossypii

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.

Lipidomics and RNA-Seq Study of Lipid Regulation in Aphis gossypii parasitized by Lysiphlebia japonica

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.

RNA-Seq study of lipid regulation in Aphis gossypii parasitized by Lysiphlebia japonica

Project description:Parasitoids were considered to have the ability to synthesize the lipid. The cotton aphids were parasitized by Lysiphlebia japonica, and Lysiphlebia japonica obtained lipids from cotton aphids. In our study,we get the 3 days parasitized aphids and unparasitized aphids and analysis the expression of the genes involved in the lipid related pathway.

A genome-wide view of transcriptional responses during Aphis glycines Matsumura infestation in soybean

Project description:Soybean aphid is one of the major limiting factors for soybean production. However, the mechanism for aphid resistance in soybean is remain enigmatic, very little information is available about the different mechanisms between antibiosis and antixenosis genotypes. Here we dissected aphid infestation into three stages and used genome-wide gene expression profiling to investigate the underlying aphid-plant interaction mechanisms. Approximately 990 million raw reads in total were obtained, the high expression correlation in each genotype between infestation and non-infestation indicated that the response to aphid was controlled by a small subset of important genes. Moreover, plant response to aphid infestation was more rapid in resistant genotypes. Among the differentially expressed genes (DEGs), a total of 901 transcription factor (TF) genes categorized to 40 families were identified with distinct expression patterns, of which AP2/ERF, MYB and WRKY families were proposed to playing dominated roles. Gene expression profiling demonstrated that these genes had either similar or distinct expression patterns in genotypes. Besides, JA-responsive pathway was domination in aphid-soybean interaction compared to SA pathway, which was not involved plant response to aphid in susceptible and antixenotic genotypes but played an important role in antibiosis one. Throughout, callose were deposited in all genotypes but it was more rapidly and efficiently in antibiotic one. However, reactive oxygen species were not involved in response to aphid attack in resistant genotypes during aphid infestation. Our study helps uncover important genes associated with aphid-attack response in antibiosis and antixenotic genotypes of soybean.
