Nematode-destroyıng fungı: ınfectıon structures, ınteractıon mechanısms and bıocontrol
(Ankara Üniversitesi Fen Fakültesi, 2020) Karakaş, Mehmet; Biyoloji; Fen Fakültesi
Fungi are pathogenic for different nematode groups, but their relationship with soil nematodes goes a grade beyond parasitism and into predation. Approximately, 200 species of taxonomically various fungi can attack active nematodes, which are effective animals nearly 0.1 to 1.0 mm long. Among these nematode-destroying fungi, only a few species are obligate parasites of nematodes; the majority are facultative saprotrophs. Nematode-destroying fungi have four general groups: (a) fungi with specialized structures (b) fungi with toxins; (c) fungi with spore germination; (d) fungi with colony-forming. Nematode-destroying fungi are natural enemies of nematodes in soil ecosystems and have potential as biocontrol agents against plant- and animal-parasitic nematodes. These predator fungi catches free-living nematodes in the soil ecosystem using traps produced by the fungal mycelium that cling to the worm, then, penetrate, kill, and digest the tissue of the nematode. Five kinds of trapping apparatus belonging to fungi are defined. These are adhesive or sticky column, adhesive or sticky knob, adhesive or sticky system, constricting and non-constricting rings.
