Project description:The genome of two isogenic lines from Aedes aegypti from Ile Royale, French Guiana, with a marked difference in resistance to deltamethrin was investigated in order to understand the genetic basis of this phenotypic difference. Genomic sequencing was performed both with Illumina short, paired reads and with Minion long reads.

Project description:General information_new_RNA The whole transcriptome of four Aedes aegypti lines has been studied: - IR13, an isofemale line from Ile Royale, French Guiana, showing a weak resistance to deltamethrin - IR03, another isofemale line from Ile Royale, French Guiana, showing a strong resistance to deltamethrin, -IR0Free, a derivative of IR03 free from the kdr1034 mutation, still showing a strong resistance to deltamethrin, - Bora-Bora, a laboratory strain sensitive to deltamethrin. Illumina RNAseq data was obtained from 4 pools of 25 individuals for each line

Project description:Custom microarrays were used to examine differential gene expression between pyrethroid resistant vs pyrethroid susceptible phenotypes of the dengue vector mosquito Aedes aegypti. Pyrethroid resistant population were from Cayenne (French Guiana, GUY), Baie Mahault (Guadeloupe, GUA) and Noumea (New Caledonia, CAL) whilst New Orleans lab colony represented the lab susceptible strain Pools of total RNA was extracted from the whole bodies of 3 day old female mosquitoes that had survived exposure to 0.06% deltamethrin (for GUY, GUA, CAL) . Single colour hybridization experiments were performed using labelled cDNA on the Agilent 'Aedes aegypti detox chip plus': A-MTAB-574. Four unique biological replicates per population were used in the study

Project description:Soil microbial community is a complex blackbox that requires a multi-conceptual approach (Hultman et al., 2015; Bastida et al., 2016). Most methods focus on evaluating total microbial community and fail to determine its active fraction (Blagodatskaya & Kuzyakov 2013). This issue has ecological consequences since the behavior of the active community is more important (or even essential) and can be different to that of the total community. The sensitivity of the active microbial community can be considered as a biological mechanism that regulates the functional responses of soil against direct (i.e. forest management) and indirect (i.e. climate change) human-induced alterations. Indeed, it has been highglihted that the diversity of the active community (analyzed by metaproteomics) is more connected to soil functionality than the that of the total community (analyzed by 16S rRNA gene and ITS sequencing) (Bastida et al., 2016). Recently, the increasing application of soil metaproteomics is providing unprecedented, in-depth characterisation of the composition and functionality of active microbial communities and overall, allowing deeper insights into terrestrial microbial ecology (Chourey et al., 2012; Bastida et al., 2015, 2016; Keiblinger et al., 2016). Here, we predict the responsiveness of the soil microbial community to forest management in a climate change scenario. Particularly, we aim: i) to evaluate the impacts of 6-years of induced drought on the diversity, biomass and activity of the microbial community in a semiarid forest ecocosystem; and ii) to discriminate if forest management (thinning) influences the resistance of the microbial community against induced drought. Furthermore, we aim to ascertain if the functional diversity of each phylum is a trait that can be used to predict changes in microbial abundance and ecosystem functioning.

Project description:Background: The soil environment is responsible for sustaining most terrestrial plant life on earth, yet we know surprisingly little about the important functions carried out by diverse microbial communities in soil. Soil microbes that inhabit the channels of decaying root systems, the detritusphere, are likely to be essential for plant growth and health, as these channels are the preferred locations of new root growth. Understanding the microbial metagenome of the detritusphere and how it responds to agricultural management such as crop rotations and soil tillage will be vital for improving global food production. Methods: The rhizosphere soils of wheat and chickpea growing under + and - decaying root were collected for metagenomics sequencing. A gene catalogue was established by de novo assembling metagenomic sequencing. Genes abundance was compared between bulk soil and rhizosphere soils under different treatments. Conclusions: The study describes the diversity and functional capacity of a high-quality soil microbial metagenome. The results demonstrate the contribution of the microbiome from decaying root in determining the metagenome of developing root systems, which is fundamental to plant growth, since roots preferentially inhabit previous root channels. Modifications in root microbial function through soil management, can ultimately govern plant health, productivity and food security.
