Abstract:
Mycorrhizae are the structural unit resulting from the symbiotic interaction between soil fungi and plant roots, and are accompanied by considerable alteration of the metabolism of both partners. In this study changes in the gene expression of Glomus intraradices inoculated tobacco roots were detected following the application of the plant defense chemical activators 2,6-dichloroisonicotinic acid (INA) or (1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH). In response to mycorrhizal fungal colonization, mRNA steady state level of the pathogen-related protein 1a (PR-1a) and the protein accumulation of PR-1a and basic chitinase were reduced. The suppression of PR-1a and basic chitinase coincided with a significant increase in the level of Zeatin riboside (ZR)-like cytokinin compounds in mycorrhizal roots compared to non-mycorrhizal controls. Application of kinetin and 6-benzylaminopurine (BAP) mixture at 10-5 M each, to tobacco leaves resulted in a significant reduction in PR-1a and basic chitinase protein levels. The possible link between the altered expression of these specific plant genes and the elevated cytokinin level in AM fungus-colonized plants is discussed.
