Bacterias promotoras del crecimiento vegetal: Mecanismos y aplicaciones

Abstract

Se denomina como PGPR (plant growth-promoting rhizobacteria) a un conjunto de bacterias que habitan en la rizosfera de las plantas y que producen en ellas todo tipo de beneficios. Potencian su crecimiento, mejorando la disponibilidad o la absorción de minerales y otro tipo de compuestos (nitratos, fosfatos, etc.), ayudan a la producción de hormonas necesarias en el desarrollo de los vegetales (fitohormonas, giberelinas…). Además protegen a plantas y cultivos contra posibles agentes patógenos y combaten la contaminación de los suelos, ya sea por contaminantes de tipo orgánico o inorgánico. Estas características hacen de las PGPR bacterias muy estudiadas a día de hoy por su potencial, no solo para la mejora en el crecimiento de cultivos o el ejercicio como agentes de biocontrol, sino también en la variedad de posibilidades tanto de descontaminación de suelos como de reforestación y recuperación de ecosistemas. Hoy en día también se están investigando cepas bacterianas modificadas genéticamente que mejoran e incluso potencian la acción e interacción con las plantas, cuando anteriormente las condiciones eran desfavorables, ya fuese debido a los cultivos, a los suelos o a los propios microorganismos.
