Specific Microbial Attachment to Root Knot Nematodes in Suppressive SoilMohamed Adam,a,b Andreas Westphal,a Johannes Hallmann,a Holger HeueraJulius K n Institut ederal Study Centre for Cultivated Plants, Braunschweig, Germanya; Division of Zoology and Nematology, Faculty of Agriculture, Cairo University, Cairo, EgyptbUnderstanding the interactions of plant-parasitic nematodes with antagonistic soil microbes could provide possibilities for novel crop protection techniques. Three arable soils have been investigated for their suppressiveness against the root knot nematode Meloidogyne hapla. For all three soils, M. hapla developed drastically fewer galls, egg masses, and eggs on tomato plants in unsterilized than in sterilized infested soil. Egg numbers had been reduced by as much as 93 . This recommended suppression by soil microbial communities. The soils substantially differed inside the composition of microbial communities and within the suppressiveness to M.Price of Dde-Dap(Fmoc)-OH hapla.6-Chlorofuro[3,4-c]pyridin-1(3H)-one Chemical name To determine microorganisms interacting with M.PMID:23443926 hapla in soil, second-stage juveniles (J2) baited in the test soil had been cultivation independently analyzed for attached microbes. PCR-denaturing gradient gel electrophoresis of fungal ITS or 16S rRNA genes of bacteria and bacterial groups from nematode and soil samples was performed, and DNA sequences from J2-associated bands had been determined. The fingerprints showed a lot of species that had been abundant on J2 but not inside the surrounding soil, particularly in fungal profiles. Fungi associated with J2 from all 3 soils had been related to the genera Davidiella and Rhizophydium, whilst the genera Eurotium, Ganoderma, and Cylindrocarpon have been specific for essentially the most suppressive soil. Among the 20 hugely abundant operational taxonomic units of bacteria precise for J2 in suppressive soil, six have been closely associated with infectious species such as Shigella spp., whereas essentially the most abundant were Malikia spinosa and Rothia amarae, as determined by 16S rRNA amplicon pyrosequencing. In conclusion, a diverse microflora especially adhered to J2 of M. hapla in soil and presumably affected female fecundity. oot knot nematodes (Meloidogyne spp.) are among essentially the most damaging pathogens of many crops worldwide and are critical pests in Europe (1). Chemical nematicides are pricey and restricted due to their adverse impact on the environment and human health, whereas cultural handle or host plant resistance are typically not sensible or not out there (2). Option management methods could include things like biological handle methods. Microbial pathogens or antagonists of root knot nematodes have higher possible for nematode suppression.
