[HTML][HTML] A «Repertoire for Repertoire» Hypothesis: Repertoires of Type Three Effectors are Candidate Determinants of Host Specificity in Xanthomonas

A Hajri, C Brin, G Hunault, F Lardeux, C Lemaire… - PLoS …, 2009 - journals.plos.org
Background The genetic basis of host specificity for animal and plant pathogenic bacteria
remains poorly understood. For plant pathogenic bacteria, host range is restricted to one or a …

High‐density genome‐wide association mapping implicates an F‐box encoding gene in Medicago truncatula resistance to Aphanomyces euteiches

…, F Debéllé, H Navier, H Miteul, A Hajri… - New …, 2014 - Wiley Online Library
The use of quantitative disease resistance ( QDR ) is a promising strategy for promoting

A Hajri, D Meyer, F Delort, J Guillaumès, C Brin… - Plant …, 2010 - Wiley Online Library
A new bacterial disease of Persian (English) walnut (Juglans regia) has been observed in
France. This disease, called vertical oozing canker (VOC), is characterized by vertical cankers …

Variations in type III effector repertoires, pathological phenotypes and host range of Xanthomonas citri pv. citri pathotypes

…, LD Noel, K Vital, S Poussier, A Hajri… - Molecular plant …, 2013 - Wiley Online Library
The mechanisms determining the host range of X anthomonas are still undeciphered, despite
much interest in their potential roles in the evolution and emergence of plant pathogenic …
