Pseudomonas fluorescens PICF7 displays an endophytic lifestyle in cultivated cereals and enhances yield in barley.

摘要: Pseudomonas fluorescens PICF7, an indigenous olive roots inhabitant, displays endophytic lifestyle in this woody crop and exerts biocontrol against the fungal phytopathogen Verticillium dahliae . Here we report microscopy evidence that strain PICF7 is also able to colonize persist on/in wheat barley root tissues. Root colonization of both cereal species followed a similar pattern previously reported olive, including inner hairs. This demonstrates can systems distant botanical species. Barley plants germinated from PICF7-treated seeds showed enhanced vegetative growth. Moreover, significant increases number grains (up 19.5%) grain weight 20.5%) per plant were scored In contrast, growth yield not significantly affected by presence PICF7. Proteomics analysis revealed different proteins exclusively found depending on or absence only one protein with hydrogen ion transmembrane transporter activity was PICF7-inoculated but controls.
