Identification of protein secretion systems and type III effectors in wood-associated bacteria of the genus Xylophilus | Microbiology Spectrum
Xylophilus species include poorly characterized plant-associated bacteria, among them the grapevine pathogen Xylophilus ampelinus, yet their molecular mechanisms of host interaction have remained larg...

Want to know more about the bacterial leaf streak pathogen #Xanthomonas oryzae pv. oryzicola and the role of rice seed trade in the pathogen's spread in West Africa? Using genome sequencing and satellite markers, we describe its population structure and molecular epidemiology doi.org/10.1128/aem....
