Resumen:
? Soil microbes can improve P use efficiency in agricultural systems.
? Penicillium bilaiae is a technology that effects plant health via its P nutrition (P mobilization and enhanced root development).
? We developed tools that allow to improve the understanding of P.bilaiae contribution to the P cycle and to make better inoculants for sustainable agriculture
? In lab based assays, hybridized strains show improved P solubilization.
? Root colonization by P. bilaiae was confirmed using a fluorescent protein-tagged isolate.
? This colonization led to significant increases in root hair number and length as well as total root length and surface area.
? An international consortium led by Novozymes and the DOE Joint Genome Institute is analyzing the genomes of 10 diverse soil Penicilia, including P. bilaiae, to determine genetic regulation of P solubilization .
? An additional mechanism is proposed whereby Penicillum bilaiae may affect root development because of phytohormone production.
