Verticillium tolerance: resistance, susceptibility, or mutualism?
Canadian Journal of Botany - Revue Canadienne de Botanique 85 (10), 903-910
Abstract: Host tolerance to plant pathogens was first recognized over a century ago and tolerant interactions involving Verticillium spp. have been studied almost as long. Historically the phenomenon has been attributed to 'intermediate resistance' or 'resistance to symptom expression'; however, rapidly developing molecular approaches to studying interactions between plants and Verticillium are beginning to question these longheld views. Recent cell and molecular studies suggest that the classical interpretations of tolerance as intermediate resistance or resistance to symptom expression may be incorrect; rather, Verticillium spp. may resemble endophytes, tolerance really being a form of susceptibility leading to mutualism. This paper reviews the evolution of our perceptions of tolerance and the technical advances which contributed to it.
