Developmental trajectories of giant cells induced by Meloidogyne incognita in tomato determined by single-cell RNA-sequencing

ABSTRACT: Plant-parasitic root-knot nematodes (Meloidogyne species) are highly polyphagous parasites that infect a wide variety of plants, including economically important crops. These parasites modulate cellular identity of terminally differentiated root cells to induce the formation of giant-cells and knot-like structures (galls), creating new organs in infected plant roots. In this study, we generated single cell RNA-seq data of galls and neighboring root tissues at two distinct stages of M. incognita infection of tomato plants.

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.

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.

Bacillus thuringiensis Cry5, Cry21, App6 and Xpp55 proteins to control the plant pest nematodes Meloidogyne javanica and M. incognita

Project description:The global imperative to enhance crop protection while preserving the environment has increased interest in the application of biological pesticides. Bacillus thuringiensis (Bt) is a Gramm-positive bacterium that can produce nematicidal proteins and accumulate them in parasporal crystals. Root-knot nematodes are obligate root plant parasitic which are distributed worldwide, causing severe damages to the infested plants and, consequently, large yield reductions. In this work, we have evaluated the toxicity of the crystal proteins Cry5, Cry21, App6, and Xpp55 against two root-knot nematodes belonging to the Meloidogyne genus (M. incognita and M. javanica). The results show that all four proteins, when solubilized, were highly toxic for both nematode species. To check the potential of using Bt strains producing nematicidal crystal proteins as biopesticides to control plant parasitic nematodes in the field, in planta assays were conducted, using two wild Bt strains which produced Cry5 or a combination of App6 and Cry5 proteins. The tests were carried out with cucumber or with tomato plants infested with M. javanica J2, subjected to irrigation with spore+cristal mixtures of the respective strains. The results showed that the efficacy of the nematicidal activity was plant-dependent, as Bt was able to reduce emerged J2 in tomato plants but not in cucumber plants. In addition, the toxicity observed in the in planta assays was much lower than expected, highlighting the challenge of the crystal proteins to exert their toxicity. This emphasizes the delivery of the Bt proteins as crucial for its use to control root-knot nematodes.

Biological Control of Root-Knot Nematode Meloidogyne incognita Infection of Tomato (Solanum lycopersicum L.) by the Oomycete Biocontrol Agent Pythium oligandrum

Project description:The biocontrol agent Pythium oligandrum, which is a member of phylum Oomycota, can control diseases caused by a taxonomically wide range of plant pathogens, including fungi, bacteria, and oomycetes. However, whether P. oligandrum could control diseases caused by plant root-knot nematodes (RKNs) was unknown. We investigated a recently isolated P. oligandrum strain GAQ1, and the P. oligandrum CBS530.74 strain, for the control of RKN Meloidogyne incognita infection of tomato (Solanum lycopersicum L.). Initially, P. oligandrum culture filtrates were found to be lethal to M. incognita second-stage juveniles (J2s) with up to 84% mortality at 24 h after treatment compared to 14% in the control group. Consistent with the lethality to M. incognita J2s, tomato roots treated with P. oligandrum culture filtrates reduced the attraction of nematodes, and the number of nematodes penetrating the roots was reduced by up to 78%. In a greenhouse pot trial, P. oligandrum GAQ1 inoculation of tomato plants significantly reduced the gall number by 58% in plants infected with M. incognita. Notably, P. oligandrum GAQ1 mycelial treatment significantly increased tomato plant height (by 36%), weight (by 27%), and root weight (by 48%). Transcriptome analysis of tomato seedling roots inoculated with the P. oligandrum GAQ1 strain identified ~2,500 differentially expressed genes. The enriched GO terms and annotations in the up-regulated genes suggested modulation of plant hormone-signaling and defense-related pathways in response to P. oligandrum. In conclusion, our results support that P. oligandrum GAQ1 can serve as a potential biocontrol agent for M. incognita control in tomato. Multiple mechanisms appear to contribute to the biocontrol effect involving direct inhibition of M. incognita, potential priming of tomato plant defenses, and plant growth promotion.

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.

Genome-wide shifts in histone modification patterns at early stage of rice infection with root-knot nematode Meloidogyne graminicola

Project description:Epigenetic processes play a crucial role in the regulation of plant stress responses, but their role in plant-pathogen interactions remains poorly understood. Although histone modifying enzymes are deregulated in galls induced by root-knot nematode (RKN, Meloidogyne graminicola) in rice, their influence on plant defence and their genome-wide impact has not been comprehensively investigated. At genome-wide level, three histone marks, H3K9ac, H3K9me2 and H3K27me3 were studied by chromatin-immunoprecipitation (ChIP)-sequencing on RKN-induced galls at 3 days post inoculation. While levels of H3K9ac and H3K27me3 were strongly enriched, H3K9me2 was generally depleted in galls versus control root tips. Differential histone peaks were generally associated with plant defence related genes. Total RNA sequencing was performed to assess the effect of histone modification changes on gene expression.
