Solanum torvum transcriptional responses to nematodes

Project description:Solanum torvum Sw is worldwide employed as rootstock for eggplant cultivation because of its vigour and resistance/tolerance to the most serious soil-borne diseasesas bacterial, fungal wilts and root-knot nematodes. A 30,0000 features custom combimatrix chip was designed and microarray hybridizations were conducted for both control and 14 dpi (day post inoculation) with Meloidogyne incognita-infected roots samples. We also tested the chip with samples from the phylogenetically-related nematode-susceptible eggplant species Solanum melongena.The genes identified from S. torvum catalogue, bearing high homology to knownnematode resistance genes, were further investigated in view of their potential role in the nematode resistance mechanism. total RNA was extracted from control and 14 days post-infection (infection with root-knot nematode Meloidogyne incognita) from roots of Solanum torvum and Solanum melongena. Three biological replicates were used for each condition and genotype for a total of 12 samples.

RNA-seq of Arabidopsis thaliana Col-0 and opr2-1 mutants over four timepoints and (mock)infection with Meloidogyne incognita

Project description:We compared the gene expression of wild-type Col-0 and a T-DNA mutant SALK_116381C (opr2-1). We either infected or mock-infected the plants with the root knot nematode Meloidogyne incognita and measured the root transcriptome after 0, 1, 4, and 7 days post infection using RNA-seq. The aim of the experiment was to determine whether opr2-1 affected gene expression patterns induced by nematode infection.

MELOHOSTRACE: Whole genome polymorphism across Meloidogyne incognita isolates showing different biological traits

Project description:High-coverage whole genome sequencing of 11 Brazilian isolates of the root-knot nematode Meloidogyne incognita, presenting different host plant preferences and different geographical origins. Four M. incognita host races had been proposed in the past, based on host (in)compatibility on four different plant strains. The objective was to assess whether genomic variations (SNP) correlate with host range compatibility, geographical origin and host plant of origin.

Identification of genes involved in the establishment of plant-microorganism interactions

Project description:affy_pathogen_medicago - In compatible interaction between plants and biotrophic microorganisms, neoformation of organs occurs to ensure an efficient relationship between both partners. During the interaction between Medicago truncatula and Sinorhizobium meliloti, bacteria induce the development of root nodule with a permanent meristem, and chronically infect plant cells from zone II before differentiating into atmospheric nitrogen fixing bacteroids. M. truncatula is also plant host for root-knot nematodes, such as Meloidogyne incognita. During this compatible pathogenic interaction, root-knot nematodes induce redifferenciation of root cells from the vascular cylinder into specialized feeding cells called “giant cells”. Hyperplasia and hypertrophy of the surrounding cells lead to the formation of typical root galls. This phenomenon invokes host pathways in common with those necessary for nitrogen-nodule formation, suggesting that nematode and rhizobia exploit a relative common strategy of plant cell infection at the cellular and molecular levels. In order to highlight key genes involved in gall and nodule developments, parallel laser microdissection of giant cells from galls and cells from zone II of nodules, followed by transcriptomic analysis, were performed. The RNA pools were extracted from these cells, amplified and used for transcriptomic studies with M. truncatula Affymetrix DNA chips. Keywords: organ comparison 12 arrays - Medicago infected with M. incognita or S. meliloti.

Below ground attack by root knot nematode Meloidogyne graminicola predisposes rice to blast disease

Project description:Magnaporthe oryzae (rice blast) and the root-knot nematode Meloidogyne graminicola are causing two of the most important pathogenic diseases jeopardizing rice production. Here, we show that root-knot nematode infestation on rice roots leads to important above-ground changes in plant immunity gene expression, which is correlated with significantly enhanced susceptibility to blast disease.

Local and systemic transcriptome and spliceome changes induced by Meloidigyne incognita in tomato roots.

Project description:The aim of study is to investigate DEGs, long non-coding RNAs and alternative splicing events in the development of galls and neighboring region compared to the non-infected whole root induced by root-knot nematode (RKN, Meloidogyne incognita). Total RNA was extracted, ribosomal depleted libraries were prepared, and then high throughput RNA sequencing was performed using the Illumina NovaSeq 6000. High quality, paired-end reads were then aligned to the tomato reference genome (Heinz1706 assembly SL4.0) and uniquely mapped reads were counted using Htseq. Finally, differentially expressed genes (DEGs) between whole roots-galls and whole roots-neighboring region were identified using DESeq package and downstream analyses were performed.

Transcription profiling of host response to root-knot nematode infection in Arabidopsis

Project description:During a compatible interaction, root-knot nematodes (Meloidogyne spp.) induce the redifferentiation of root cells into multinucleate nematode feeding cells giant cells. These hypertrophied cells result from repeated nuclear divisions without cytokinesis, are metabolically active and present features typical of transfer cells. Hyperplasia of the surrounding cells leads to formation of the typical root gall. We investigate here the plant response to root-knot nematodes.
