Production of extracellular enzymes in the entomopathogenic fungus Verticillium lecanii
This study investigates the mechanisms as well as strategies for purification and characterization of potential enzymes involved in pathogenesis of entomopathogenic fungi. The test strain of Verticillium lecanii that was screened, during the present investigation, proved to be an efficient producer of protein and polysaccharide degrading enzymes (amylase, protease, and lipase), hence indicating...
متن کاملAssociation of the Plant-beneficial Fungus Verticillium lecanii with Soybean Roots and Rhizosphere.
Colonization of soybean roots by the biocontrol fungus Verticillium lecanii was studied in vitro and in situ. For in vitro experiments, V. lecanii was applied to soybean root tip explant cultures. Four weeks after inoculation, the fungus grew externally on at least half of the roots (all treatments combined), colonizing 31% to 71% of root length (treatment means). However, when a potato dextros...
متن کاملHirsutella rhossiliensisand Verticillium chlamydosporium as Biocontrol Agents of the Root-knot Nematode Meloidogyne hapla on Lettuce.
Hirsutella rhossiliensis and Verticillium chlamydosporium infected second-stage juveniles (J2) and eggs of Meloidogyne hapla, respectively, in petri dishes and in organic soil in pots planted to lettuce in the greenhouse. In vitro, H. rhossiliensis produced 78 to 124 spores/infected J2 of M. hapla. The number of J2 in roots of lettuce seedlings decreased exponentially with increasing numbers of...
متن کاملThe Effects of Paecilomyces lilacinus on the Pathogenesis of Meloidogyne Javanica and Tomato Plant Growth Parameters
The present study is based on the investigation of a soil hyphomyces, Paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode Meloidogyne javanica on tomato in greenhouse conditions. P. lilacinus, effectively promoted the growth of plants inoculated with M. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...
متن کاملEfficacy Evaluation of Fungus Syncephalastrum racemosum and Nematicide Avermectin against the Root-Knot Nematode Meloidogyne incognita on Cucumber
The root-knot nematode (RKN) is one of the most damaging agricultural pests.Effective biological control is need for controlling this destructive pathogen in organic farming system. During October 2010 to 2011, the nematicidal effects of the Syncephalastrum racemosum fungus and the nematicide, avermectin, alone or combined were tested against the RKN (Meloidogyne incognita) on cucumber under po...
