Characterization and Phylogenetic Analysis of Magnaporthe spp. strains on Various Hosts in Iran
Background: Populations of Magnaporthe, the causal agent of rice blast disease, are pathotypically and genetically diverse and therefore their interaction with different rice cultivars and also antagonistic microorganisms are very complicated. Objectives: The objectives of the present study were to characterize phylogenetic relationships of 114 native Magnaporthe strains, isolated from rice a...
متن کاملEvolutionary transitions in bacterial symbiosis.
Diverse bacterial lineages form beneficial infections with eukaryotic hosts. The origins, evolution, and breakdown of these mutualisms represent important evolutionary transitions. To examine these key events, we synthesize data from diverse interactions between bacteria and eukaryote hosts. Five evolutionary transitions are investigated, including the origins of bacterial associations with euk...
متن کاملFrom Many Hosts, One Accidental Pathogen: The Diverse Protozoan Hosts of Legionella
The 1976 outbreak of Legionnaires' disease led to the discovery of the intracellular bacterial pathogen Legionella pneumophila. Given their impact on human health, Legionella species and the mechanisms responsible for their replication within host cells are often studied in alveolar macrophages, the primary human cell type associated with disease. Despite the potential severity of individual ca...
متن کاملThe targeting of plant cellular systems by injected type III effector proteins.
The battle between phytopathogenic bacteria and their plant hosts has revealed a diverse suite of strategies and mechanisms employed by the pathogen or the host to gain the higher ground. Pathogens continually evolve tactics to acquire host resources and dampen host defences. Hosts must evolve surveillance and defence systems that are sensitive enough to rapidly respond to a diverse range of pa...
متن کاملTwo gut community enterotypes recur in diverse bumblebee species
Pollinating insects are key to the evolutionary and ecological success of fl owering plants and enable much of the diversity in the human diet. Gut microbial communities likely impact pollinators in diverse ways, from nutrition to defense against disease [1,2]. Honeybees and bumblebees harbor a simple yet specialized gut microbiota [3] dominated by several newly described bacterial species, inc...
