Project description:Cacao, spinach and carrot are three important crops with high valuable markets. For these species there isn't already an available genome-wide annotation of small rna. Here, for the first time, we sequenced and annotated small RNAs.

Project description:Food-borne illness arising for Shiga-toxigenic Escherichia coli is often linked to consumption of fruit and vegetables as the bacteria have the ability to interact with plants and use them as alternative or secondary hosts. Attachment of the bacteria to host tissue is one of the first steps in the interaction, and, as with mammalian hosts, has shown to be mediated by a combination of non-specific and specific adhesin-mediated interactions. We took a high-throughput positive-selection approach to investigate adherence mechanisms for E. coli O157:H7 isolate Sakai by inoculating a BAC clone library onto spinach, which was quantified by microarray hybridisation and gene loci enrichment measured using a Bayesian hierarchical model. The screen involved four successive rounds of adherence to spinach roots, resulting in 115 CDS credible candidates, covered by seven contiguous genomic regions. Two candidates regions selected for functional assessment included a chaperone-usher fimbrial gene cluster (loc6) and the type two secretion system (T2SS). The TS22 was found to significantly enhance binding to spinach roots and leaves, demonstrated with a BAC-T2SS clone and by mutagenesis of the secretin protein, EtpD. Both etpD and the inner membrane anchor protein gene etpC were expressed at 18 degree celsius, and expression of etpD was demonstrated for STEC (Sakai) resident in the apoplastic spaces in spinach leaf tissue. Together, these data indicate a novel function for STEC T2SS in adherence to plant tissue. Experiment 1: screening E coli O157:H7 Sakai genes for adherence to spinach roots. A BAC library of Sakai clones in an E coli DH10B background (which has poor root adherence) defined as the 'Input pool', was incubated with spinach roots for 4 rounds of enrichment, defined as the 'Output pool'. Control samples (defined as 'Input control' & 'Output control') were cultures of pV41 vector only. DNA extractions from test pools were labelled with Cy3 throughout. DH10B DNA was used for grid alignment and labelled with Cy5 throughout.

Project description:Spinach (Spinacia oleracea L.) is an economically important and globally consumed popular leafy vegetable that is heat-sensitive. Heat stress caused by global climate change is one of the primary deleterious elements limiting spinach production worldwide. Little work has been done to explore the heat-responsive mechanisms of spinach under high temperature-induced stress. In the present study, we used iTRAQ-based proteomic and transcriptomic approaches to investigate physiological, metabolic, and proteomic responses of spinach in response to day / night temperature of 35°C / 25°C compared to 20°C / 15°C for 4 days. A total of 3,543 differentially expressed genes (DEGs) were detected using transcriptome sequencing, of which 2,086 DEGs were downregulated and 1,457 were upregulated. The DEGs were mainly involved in superoxide dismutase activity, catalase, and peroxidase activity. A total of 3,246 differentially abundant proteins were detected using iTAQ-based quantitative proteomic approach, from which 567 differentially expressed proteins (DEPs) (277 upregulated and 290 downregulated) were identified. DEPs were mainly assigned to pathways related to metabolism, signal transduction, protein degradation, defense, and antioxidant. Four genes - superoxide dismutase (SOD, LOC110788339), catalase (CAT, LOC110790286), peroxidase (POD, LOC110775253), and heat shock protein (HSP, LOC110799288) - were validated using quantitative real-time PCR (qRT-PCR) to verify the proteomic and transcriptomic analyses, showing different transcriptional and translational expression levels. The findings of this study provide a fundamental understanding of the metabolic pathways and biological processes that control adaptation to heat stress in spinach, and provide novel insight into the development of heat-tolerant spinach.

Project description:Elevated temperature limits plant growth and reproduction and poses a growing threat to agriculture. Plant heat stress response is highly conserved and fine-tuned in multiple pathways. Spinach (Spinacia oleracea L.) is a cold tolerant but heat sensitive green leafy vegetable. In this study, heat adaptation mechanisms in spinach sibling inbred heat-tolerant line Sp75 were investigated using physiology, proteomics, and phosphoproteomics approaches. The abundance patterns of 911 heat stress-responsive proteins, and phosphorylation level changes of 48 phosphopeptides representing 45 phosphoproteins indicated that heat induced calcium-mediated signaling, ROS homeostasis, endomembrane trafficking, and cross-membrane transport pathways, as well as > 15 transcription regulation factors. Although photosynthesis was inhibited, diverse primary and secondary metabolisms were employed for enhancing thermotolerance, such as glycolysis, pentose phosphate pathway, amino acid metabolism, fatty acid metabolism, nucleotide metabolism, vitamin metabolism, and isoprenoid biosynthesis. These data constitutes a heat stress-responsive metabolic atlas in spinach, which will springboard further investigation into the sophisticated molecular mechanism of plant heat adaptation and inform spinach molecular breeding initiatives.

Conditions as for Experiment 1 (E-MTAB-5923), but no spinach root present. Two BAC clones (BAC2B5 & BAC2B24) used for additional positive controls.
