Morphological Variations in Conidia of Arthrobotrys oligospora on Different Media

Most commonly occurring predacious fungus Arthrobotrys oligospora showed great variation in size and shape of conidia on some media. The formation of larger conidia was recorded on beef extract and nutrient agar media. The length of conidia in Richard's YPSS, Sabouraud's, PDA and corn meal agar media was of medium size while smaller conidia were produced on Czapek's, Jensen's, Martin's medium. ...

Surface polymers of the nematode-trapping fungus Arthrobotrys oligospora.

The nematophagous fungus Arthrobotrys oligospora captures nematodes using adhesive polymers present on special hyphae (traps) which form a three-dimensional network. To understand further the adhesion mechanisms, A. oligospora surface polymers were visualized by transmission electron microscopy and characterized by chemical methods. Both traps and hyphae were surrounded by a fibrillar layer of ...

Genomic and Proteomic Analyses of the Fungus Arthrobotrys oligospora Provide Insights into Nematode-Trap Formation

Nematode-trapping fungi are "carnivorous" and attack their hosts using specialized trapping devices. The morphological development of these traps is the key indicator of their switch from saprophytic to predacious lifestyles. Here, the genome of the nematode-trapping fungus Arthrobotrys oligospora Fres. (ATCC24927) was reported. The genome contains 40.07 Mb assembled sequence with 11,479 predic...

Nematophagous fungus Arthrobotrys oligospora mimics olfactory cues of sex and food to lure its nematode prey

To study the molecular basis for predator-prey coevolution, we investigated how Caenorhabditis elegans responds to the predatory fungus Arthrobotrys oligospora. C. elegans and other nematodes were attracted to volatile compounds produced by A. oligospora. Gas-chromatographic mass-spectral analyses of A. oligospora-derived volatile metabolites identified several odors mimicking food cues attract...

استفاده از تعامل نماتد Caenorhabditis elegans، قارچ Arthrobotrys oligospora و باکتری Bacillus subtilis در کنترل نماتد Meloidogyne javanica

در این تحقیق از تعامل نماتد Caenorhabditis elegans، قارچ Arthrobotrys oligospora و باکتری Bacillus subtilis در کنترل نماتد مولد گره ریشه Meloidogyne javanica استفاده شد. باکتری مذکور جهت تحریک سیستم دفاعی گیاه در بدو تیمار و به عنوان غذای نماتد C. elegans و نماتد C. elegans به منظور افزایش تولید تله استفاده شد. قارچoligospora A. پس از 72 ساعتموجب مرگ و میر 77% لاروهای نماتد M. javanica ‌گردید، ...
