Abstract (auf Englisch):
Disease
emergence
is a growing threat to agricultural productivity worldwide, yet
plant pathology
is primarily focused on populations sampled from cultivated
crops. Epidemiological
and evolutionary investigations of crop disease emergence are
generally
hindered by the absence of sufficient knowledge of the identity
and
distribution of wild hosts and difficulty identifying pathogen
symptom
production in the wild. There is increasing evidence
demonstrating the
importance of environmental reservoirs in contributing to
disease emergence
however. Many human infectious disease outbreaks have
environmental or zoonotic
origins, and recent studies of fungal plant pathogen emergence
have revealed
important links with wild populations. Such studies of bacterial
plant
pathogens are rare. The emergence of Pseudomonas
syringae pv. actinidiae
(Psa) over the last
three decades -
concomitant with the domestication of its kiwifruit (Actinidia spp.) host - offers a unique opportunity
to understand
the relationship between wild and cultivated populations of both
plants and
microbes and the ecological and evolutionary factors shaping
plant immunity and
driving the origins of disease. I will present recent work
investigating Psa’s
wild origins in East Asia and
evolution in agricultural environments.
