Identification and fine mapping of Pi33, the rice resistance gene corresponding to the Magnaporthe grisea avirulence gene ACE1
Romain Berruyer,Henri Adreit,Joëlle Milazzo,Sylvain Gaillard,Angélique Berger,Waly Dioh,Waly Dioh,Marc-Henri Lebrun,Didier Tharreau +8 more
TL;DR: The resistance gene corresponding to the cloned avirulence gene ACE1 was identified using pairs of isogenic strains of Magnaporthe grisea differing only by their ACE1 allele, mapping on the short arm of rice chromosome 8 using progenies from the crosses IR64 (resistant) × Azucena (susceptible) andAzucena × Bala (resistant).
Journal ArticleDOI
Sex at the origin: an Asian population of the rice blast fungus Magnaporthe oryzae reproduces sexually
Dounia Saleh,Dounia Saleh,Peng Xu,Ying Shen,Chenguyn Li,Henri Adreit,Joëlle Milazzo,Virginie Ravigné,Eric Bazin,Jean-Loup Nottéghem,Elisabeth Fournier,Didier Tharreau +11 more
TL;DR: It is concluded that a contemporary population of M. oryzae, pathogenic on rice, reproduces sexually in natura in southeast Asia, providing evidence for the loss of sexual reproduction by a fungal plant pathogen outside its centre of origin.
Journal ArticleDOI
South-East Asia is the center of origin, diversity and dispersion of the rice blast fungus, Magnaporthe oryzae.
TL;DR: It is confirmed that crop domestication may have considerable influence on the pestification process of natural enemies and a scenario of early evolution of M. oryzae on rice that matches the past history of rice domestication is suggested.
Journal ArticleDOI
Pathogen effectors and plant immunity determine specialization of the blast fungus to rice subspecies
Jingjing Liao,Huichuan Huang,Isabelle Meusnier,Henri Adreit,Aurélie Ducasse,François Bonnot,Lei Pan,Xiahong He,Thomas Kroj,Elisabeth Fournier,Didier Tharreau,Pierre Gladieux,Jean-Benoit Morel +12 more
TL;DR: It is indicated that major differences in several components of basal immunity and effector-triggered immunity of the japonica and indica rice varieties are associated with specialization of M. oryzae and may limit the spread of the pathogen within the Yuanyang agro-system.
Journal ArticleDOI
Asexual reproduction induces a rapid and permanent loss of sexual reproduction capacity in the rice fungal pathogen Magnaporthe oryzae: results of in vitro experimental evolution assays.
TL;DR: It is shown for the first time that, in the absence of sexual reproduction, female-sterile mutants of M. oryzae rice strains can arise and increase in abundance in asexual generations.
