Pathogenic and mutualistic microbes actively suppress plant defense by secreting effector proteins to manipulate the host responses for their own benefit. Current knowledge about fungal effectors has been mainly derived from biotrophic and hemibiotrophic plant pathogenic fungi and oomycetes with restricted host range. We studied colonization strategies of the root endophytic basidiomycete Pirif...

β-glucans are well-known modulators of the immune system in mammals but little is known about β-glucan triggered immunity in planta. Here we show by isothermal titration calorimetry, circular dichroism spectroscopy and nuclear magnetic resonance spectroscopy that the FGB1 gene from the root endophyte Piriformospora indica encodes for a secreted fungal-specific β-glucan-binding lectin with dual ...

Some Plant Growth-Promoting Rhizobacteria (PGPR) can induce protection against pathogens, increasing plant tolerance to various diseases. This so-called biocontrol activity is replacing harmful practices in agriculture caused by the use of agrochemicals. Azospirillum brasilense one PGPR already effectively used as a resistance inducer several crops. The aim this study was evaluate protective ef...

Beans are one of the most important foods for majority world's population, and Brazil is third largest producer. This production can be affected by pests diseases, such as gray stem rot, caused fungus Macrophomina phaseolina, which difficult to control due low efficiency chemical products. One viable alternatives use microorganisms and/or secondary metabolites pathogen promote plant growth. The...
