Plant-parasitic nematodes are major agricultural pests worldwide and novel approaches to control them sorely needed. We report the draft genome sequence of root-knot nematode Meloidogyne incognita, a biotrophic parasite many crops, including tomato, cotton coffee. Most assembled this asexually reproducing nematode, totaling 86 Mb, exists in pairs homologous but divergent segments. This suggests that ancient allelic regions M. incognita evolving toward effective haploidy, permitting new...
The European legislative on the use of different control strategies against plant-parasitic nematodes, with particular reference to pesticides, is constantly evolving, sometimes causing confusion in sector operators. This article highlights nematode management allowed C Zone Union, which includes chemical nematicides (both fumigant and non-fumigant), agronomic (crop rotations, biofumigation, cover crops, soil amendments), physical method solarization, application biopesticides (fungi,...
Climate changes include the intensification of drought in many parts world, increasing its frequency, severity and duration. However, under natural conditions, environmental stresses do not occur alone, and, addition, more stressed plants may become susceptible to attacks by pests pathogens. Studies on impact arbuscular mycorrhizal (AM) symbiosis tomato response water deficit showed that several drought-responsive genes are differentially regulated AM-colonized (roots leaves) during deficit....
Abstract The genome of pea (Pisum sativum) contains genes encoding a family distinct lipoxygenases (LOX). Among these, LOXN2 showed eight exons 93.7-kD enzyme, harboring two C-terminal deletions and an unusual arginine/threonine-tyrosine motif in the domain considered to control substrate specificity. LOXN2, when overexpressed yeast, exhibited normal enzyme activity with optimum at pH 4.5, dual positional specificity by releasing 3:1 ratio C-9 C-13 oxidized products. predicted structure...
Few studies have been carried out on the effect of ozonated water (O3 wat) oxidative stress root systems and, in particular, combination with biotic stress. The aim this study was to determine whether aqueous ozone is effective control root-knot nematode (RKN) infection and investigate concomitant changes basal defence system. A tomato cultivar susceptible Meloidogyne incognita treated O3 wat as a soil drench. No negative effects were seen following application comparison under exposure...
Plant parasitic nematodes are a serious threat to crop production worldwide and their control is extremely challenging. Fungal volatile organic compounds (VOCs) provide an ecofriendly alternative synthetic nematicides, many of which have been withdrawn due the risks they pose humans environment. This study investigated biocidal properties two fungal VOCs, 1-Octen-3-ol 3-Octanone, against widespread root-knot nematode Meloidogyne incognita. Both VOCs proved be highly toxic infective...
The response of resistant wheat-Aegilops ventricosa introgression line H-93-8 and its susceptible parent, Triticum aestivum H-10-15, to Ha71 Spanish population Heterodera avenae was studied determine the changes in peroxidase gene expression during incompatible compatible wheat-nematode interactions. Twenty genes were characterized from both 211 expressed sequence tags 259 genomic DNA clones. Alignment deduced amino acid sequences phylogenetic clustering with peroxidases other plant species...
A cDNA of 312 bp, similar to polygalacturonase-inhibiting proteins (PGIPs), was isolated by cDNA-amplified fragment length polymorphism (cDNA-AFLP) from pea roots infected with the cyst nematode Heterodera goettingiana. The deduced amino acid sequence obtained complete Pspgip1 coding very PGIPs described several other plant species, and identical in both MG103738 Progress 9 genotypes, resistant susceptible H. goettingiana, respectively. Reverse transcription-polymerase chain reaction...
Microscopic observations and transcriptomic RNA-Seq analyses were applied to investigate the effect of water stress during formation tomato galls 1 2 weeks after inoculation with root-knot nematode
Plant parasitic nematodes (PPN) are important pests of numerous agricultural crops especially vegetables, able to cause remarkable yield losses correlated soil nematode population densities at sowing or transplant. The concern on environmental risks, stemming from the use chemical pesticides acting as nematicides, compels their replacement with more sustainable pest control strategies. To verify effect aqueous extracts agro-industry waste coffee silverskin (CS) and brewers' spent grain (BSG)...

In this study, combination different abamectin concentrations ranging from 1.125 36 µg/mL x exposure times 24 384 h were tested on in hatching test. induced mortality with LD50 value range 13.23 (after h) 2.90 h). A glasshouse experiment was also performed pots filled soil infected presence...
Analysis of a genomic fragment from the plant parasitic nematode Meloidogyne artiellia revealed presence gene which, in bacteria, is involved formation polyglutamate capsule. Searching various databases, including Caenorhabditis elegans genome sequence and large EST datasets variety nematodes, showed that no similar genes have been identified other nematodes or any eukaryotic organisms. The M. has typical structure its mRNA present intestine. expressed all life cycle stages tested. These...
Abstract BACKGROUND Ozonated water (O 3 wat) soil drench and/or foliar spray applications were evaluated for their potential to control the root‐knot nematode Meloidogyne incognita (RKN) and airborne pathogen Tomato spotted wilt virus (TSWV) in tomato. We investigated how O wat modulates salicylic acid/jasmonic acid/ethylene (SA/JA/ET) signalling network host, locally systemically, induce resistance virus. RESULTS The application as was effective reducing number of galls egg masses, but did...
The physical map for seventeen WNA genes on the mitochondrial genome of dicotyledonous plant Heiianthus annuus has been established. Eleven are genuine genes, while other six show a high degree similarity with chloro-plast counterparts.The exception trnS(GCT) and chloroplast-like trnV tmP, expressed.The comparison organization some tRNA in H. that similar detectable plants reveals their association is common to several dicotyledons.
