| colonization by the arbuscular mycorrhizal fungus glomus versiforme induces a defense response against the root-knot nematode meloidogyne incognita in the grapevine (vitis amurensis rupr.), which includes transcriptional activation of the class iii chitinase gene vch3. | inoculation of the grapevine (vitis amurensis rupr.) with the arbuscular mycorrhizal (am) fungus glomus versiforme significantly increased resistance against the root-knot nematode (rkn) meloidogyne incognita. studies using relative quantitative reverse transcription-pcr (rqrt-pcr) analysis of grapevine root inoculation with the am fungus revealed an up-regulation of vch3 transcripts. this increase was greater than that observed following infection with rkn. however, inoculation of the mycorrhiz ... | 2006 | 16326755 |
