Project description:Nanomaterials (NMs) are on the nanoscale level range ca. 1-100 nm and due to the peculiar physico-chemical properties are widely used in different areas. The present study aimed to characterize the responses of zucchini (Cucurbita pepo L.) treated with copper oxide (CuO) NPs from seed germination to the flowering stage. CuO NPs treatment did not negatively impact plant morphology and growth as well as the pollen formation and viability. Physiological analyses were followed by a complete RNAseq-based transcriptomic analysis in the different plant tissues. Mitochondrial and chloroplast functions emerged as a critical component in plant response. Evidence of CuO NPs internalization and biotransformation was a driving force to measure the impacts at both physiological and molecular levels.

Project description:Cucurbita pepo is high susceptible to Zucchini yellow mosaic virus (ZYMV) and the resistance found in several wild species does not provide complete or broad-spectrum resistance. In this study, a source of tolerance introgressed in C. pepo (381e) from C. moschata, in True French (TF) background, was investigated 12 days after inoculation (DPI) at transcriptomic and genomic levels. A comparative RNA-seq experiment, allowed to evaluate more than 33,000 expressed transcripts and to identify 146 differentially expressed genes (DEGs) in 381e, mainly involved in photosynthesis, transcription, cytoskeleton organization and callose synthesis. By contrast, the susceptible line True French triggered oxidative processes related to response to biotic stimulus and two synaptotagmin (SYTA) genes, key regulators of plant virus intercellular movement. Finally, transcripts mapping allowed the identification of two regions rich in SNPs (Single Nucleotide Polymorphisms) on linkage group 1 and linkage group 8, putatively introgressed from C. moschata, containing a putative disease resistance protein (CNL gene) exclusively expressed in 381e. In conclusion, 381e transcriptome analysis confirmed a globally improved plant fitness by reducing the effect of viral infection and showed the activation of genes putatively involved in tolerance to ZYMV. Our work provides new insight into plant virus recovery process to ZYMV.

Project description:Total RNA was isolated from different tissues (leaf, stem and flesh, rind and placenta of the fruits) using TRIzol reagent and small RNA libraries were generated from four cucurbit species: bottle gourd (Lagenaria siceraria (accession Grif 1617 collection from India)), Cucurbita moschata (accession Grif 14244 Early Butternut) Cucurbita pepo (accession NSL98075 Table King), and watermelon (Citrullus lanatus var. lanatus) (PI 438676 Charleston Grey) by pooling equimolar amounts of total RNA from the aforesaid tissues. Construction of small RNA libraries from size fractionated RNA was carried out as described previously. In brief, small RNA fractions of 18–28 nt were isolated from 15% denaturing polyacrylamide gels and sequentially ligated to 5′ and 3′ RNA adapters. Small RNAs ligated with adapters were converted to DNA by RT-PCR following Solexa protocol. The final PCR product was gel purified and sequenced by Genome Analyser II (Illumina).

In brief, small RNA fractions of 18–28 nt were isolated from 15% denaturing polyacrylamide gels and sequentially ligated to 5? and 3? RNA adapters. Small RNAs ligated with adapters were converted to DNA by RT-PCR following Solexa protocol. The final PCR product was gel purified and sequenced by Genome Analyser II (Illumina).

Project description:Podosphaera xanthii is the main causal agent of powdery mildew (PM) disease for Cucurbita pepo. Disease control is attained principally by applications of chemical fungicides, along with parallel use of tolerant crop varieties and alternate application of elicitors to control development of disease resistance. To get insight into C. pepo molecular responses to P. xanthii infection and elicitor treatment we studied the proteomic profile differences at the phyllosphere of a zucchini cultivar susceptible to PM, at the onset of P. xanthii (PX) infection and after application of Reynoutria sachalinensis (RS) plant extract, respectively, using a nano-LC-HRMS/MS, Q-Exactive-Orbitrap approach. Analysis of peptide sequences regarding four treatment groups (Control; PX; RS; and RSPX (PX-infected priorly treated with RS)) resulted in 2070 CuGenDB annotations. Three comparisons (treatments vs Control) encompassed most of the Differentially Expressed Proteins (DEPs). In these three comparisons, KEGG and Gene Ontology functional analyses highlighted unique differentially enriched pathways -some of which including highly expressed proteins- in PX-related (Proteasome, Pentose phosphate pathway, and Carbon fixation), RS-related (Biosynthesis of Secondary metabolites, Flavonoids, and Starch and Sucrose metabolism), and RSPX-related (Pyruvate metabolism and Polycomb repressive complex) comparisons respectively, suggesting distinct mechanisms of early plant responses modulated by PX and RS. Furthermore, in four out of six comparisons the Thiamine metabolism pathway was found to be enriched, suggesting a pivotal role in PX-induced responses.

Project description:Nectaries are the glands responsible for nectar secretion. To understand the genetic programming underlying nectar production, male and female squash(Cucurbita pepo) floral nectaries at four different time points (pre-secretion #1, pre-secretion #2, secretory, and post-secretory) in biological triplicate were collected, with RNA being isolated and subjected to Illumina RNA-seq analysis.
