Root recognition reflects parasite preferences


Figure 1
Plant-on-plant parasitism occurs widely amongst angiosperms. Fernández-Aparicio et al. (Córdoba and Palos de la Frontera, Spain, pp. 423–431) cite papers indicating that this life-style has arisen independently in 17 angiosperm families, giving rise to approx. 4000 parasitic species. Amongst these there is variation in the extent to which the parasite depends on the host and in the degree of specialization in host preference. For all parasitic plants there is the problem of detecting the host; for the specialist parasites this means detecting only the correct host. The authors have focussed on one aspect of this, namely the effects of root exudates of host and non-host plants on the germination of seeds of specialist and of more generalist parasites in the broomrape genera Orobanche and . . .
