Pseudozyma aphidis induces ethylene-independent resistance in plants.
Species of the epiphytic fungus Pseudozyma are not pathogenic to plants and can be used as biocontrol agents against plant pathogens. Deciphering how they induce plant defense might contribute to their use for plant protection and expand our understanding of molecular plant-pathogen interactions. Here we show that Pseudozyma aphidis isolate L12, which is known to induce jasmonic acid- and salic...
متن کاملThe epiphytic fungus Pseudozyma aphidis induces jasmonic acid- and salicylic acid/nonexpressor of PR1-independent local and systemic resistance.
Pseudozyma spp. are yeast-like fungi, classified in the Ustilaginales, which are mostly epiphytic or saprophytic and are not pathogenic to plants. Several Pseudozyma species have been reported to exhibit biological activity against powdery mildews. However, previous studies have reported that Pseudozyma aphidis, which can colonize plant surfaces, is not associated with the collapse of powdery m...
متن کاملBioluminescence imaging of Clavibacter michiganensis subsp. michiganensis infection of tomato seeds and plants.
Clavibacter michiganensis subsp. michiganensis is a Gram-positive bacterium that causes wilting and cankers, leading to severe economic losses in commercial tomato production worldwide. The disease is transmitted from infected seeds to seedlings and mechanically from plant to plant during seedling production, grafting, pruning, and harvesting. Because of the lack of tools for genetic manipulati...

متن کاملTomato fruit and seed colonization by Clavibacter michiganensis subsp. michiganensis through external and internal routes.
The Gram-positive bacterium Clavibacter michiganensis subsp. michiganensis, causal agent of bacterial wilt and canker of tomato, is an economically devastating pathogen that inflicts considerable damage throughout all major tomato-producing regions. Annual outbreaks continue to occur in New York, where C. michiganensis subsp. michiganensis spreads via infected transplants, trellising stakes, to...
