Bioactive Volatiles from an Endophytic Daldinia cf. concentrica Isolate Affect the Viability of the Plant Parasitic Nematode Meloidogyne javanica
Plant-parasitic nematodes form one of the largest sources of biotic stress imposed on plants, and are very difficult to control; among them are the obligate parasites, the sedentary root-knot nematodes (RKNs)-Meloidogyne spp.-which are extremely polyphagous and exploit a very wide range of hosts. Endophytic fungi are organisms that spend most of their life cycle within plant tissue without caus...
متن کاملUse of the Endophytic Fungus Daldinia cf. concentrica and Its Volatiles as Bio-Control Agents
Endophytic fungi are organisms that spend most of their life cycle within plant tissues without causing any visible damage to the host plant. Many endophytes were found to secrete specialized metabolites and/or emit volatile organic compounds (VOCs), which may be biologically active and assist fungal survival inside the plant as well as benefit their hosts. We report on the isolation and charac...
متن کاملMeloidogyne javanica Parasitic on Peanut.
Peanut fields in four governorates of Egypt were surveyed to identify species of Meloidogyne present. Fourteen populations obtained from peanut roots were all identified as M. javanica based on perineal patterns, stylet and body lengths of second-stage juveniles, esterase phenotypes, and restriction fragment length polymorphisms of mtDNA. Three of 14 populations, all from contiguous fields in t...
متن کاملDiaporthin and Orthosporin from the Fruiting Body of Daldinia concentrica
In our continuing study on the chemical constituents in the fruiting bodies of Daldinia concentrica, diaporthin and orthosporin were isolated. Their chemical structures were assigned based on various spectral studies. Diaporthin and orthosporin, phytotoxins previously found in Aspergillus ochraceus, were isolated from wood-rotting mushroom D. concentrica for the first time.
متن کاملEffect of chitosan on root-knot nematode, Meloidogyne javanica
In our study two different chitosan with low and high molecular weight at different dilutions i.e. standard, 1:1, 1:2, 1:3, 1:4, 1:5 and 1:10 were evaluated against root-knot nematode, Meloidogyne javanica in vitro and in vivo under greenhouse conditions. In vitro results revealed that both chitosan with all used concentrations significantly reduced the egg hatching when compared to control. No...
