Project description:The complete mitochondrial genome of the Aster leafhopper Macrosteles quadrilineatus was sequenced using an Illumina-based next-generation sequencing approach. The genome is 16,626 bp in length with 78.0% AT content. It encodes 37 typical mitochondrial genes including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 A + T-rich region. Two tandem repeats were identified within the A + T-rich region. One tRNA gene rearrangement (trnW-trnC-trnY→trnC-trnW-trnY) was found between nd2 and cox1.
Project description:Hemipteran insects are ubiquitous inhabitants of the phyllosphere. Changes in microbial phyllosphere communities have recently been demonstrated following infestation by Macrosteles quadrilineatus (Aster Leafhopper). Although epiphytic Salmonella enterica populations naturally decline in the phyllosphere of plants, M. quadrilineatus infestation facilitated the growth of the bacterial pathogen populations. Here, we demonstrate that cellular damage by insect stylet penetration results in a localized beneficial niche on the leaf surface, leading to enhanced S. enterica populations. We measured S. enterica populations and colonization patterns on plants infested with Hemipterans with distinct feeding behaviors. M. quadrilineatus infestation resulted in higher solute leakage and significantly greater bacterial populations than plants absent of insects. Following immigration via contaminated irrigation water, the highest populations of S. enterica are naturally found on the tips of tomato leaflets. We discovered M. quadrilineatus feeding preference altered the natural distribution of S. enterica populations, and that the presence of S. enterica altered the distribution of probing attempts. These findings elucidate how cellular damage resulting from insect feeding drives changes in bacterial colonization of the phyllosphere.
Project description:<div>Olive (<i>Olea europaea</i>) has a long history of medicinal and nutritional values own to it rich in polyphenol and fatty acids (FAs) in fruits. In order to better understand the biosynthesis important of these metabolites, we generated comprehensive Iso-Seq full-length and illumina RNA-seq transcriptome, and targeted metabolomics dataset of different olive fruits maturity. The targeted metabolomics by using both GC/MS and LC/MS were totally quantified 35 FAs and 13 polyphenols. Iso-Seq library was constructed and sequenced by PacBio Sequel System, and a total of 5,891,652 (10.55 G) with an average length of 1,791 subreads were obtained. 492,350 circular consensus sequences (CCSs) were formed after merging and error correction through subread comparison. Of the 492,350 CCSs, 399,263 were found to be full-length non chimera (FLNC) reads, and 187,517 consensus reads were finally obtained by using clustering algorithm of Iterative clustering for error (IEC). These multiomics data provide a foundation to elucidate the mechanisms regulating biosynthesis of polyphenol and FAs during the maturation of olive fruits.</div><div><b><br></b></div><div><b>Polyphenols UPLC-MS</b> protocols and data are reported in the current study <b>MTBLS814</b>.</div><div><br></div><div><b>GC-MS</b> protocols and data associated to this study are reported in <b><a href="https://www.ebi.ac.uk/metabolights/MTBLS855">MTBLS855</a></b>.</div><div><br></div><div><span _ngcontent-iov-c3="" class="ng-star-inserted"><b>Tyrosol only UPLC-MS</b> <span _ngcontent-iov-c3="" class="ng-star-inserted">protocols and data associated to this study are reported in <b><a href="https://www.ebi.ac.uk/metabolights/MTBLS1127">MTBLS1127</a>.</b></span></span></div><div><br></div><div><br></div>
