| dc.description | Free-living bacteria with various abilities related to plant growth and health have been termed plant growth promoting rhizobacteria (PGPR). PGPRs promote plant growth through various modes of action, either directly or indirectly. The benefits provided by these bacteria may include increased nutrient availability, phytohormone production, shoot and root development, protection against various phytopathogens, and disease reduction. In addition, PGPR can help plants resist abiotic stresses such as salinity, drought, and production of enzymes that detoxify plants of heavy metals. PGPRs have become an important strategy in sustainable agriculture, due to the possibility of reducing synthetic fertilizers and pesticides, promoting growth and plant health, and improving soil quality. There are many studies related to PGPR in the literature. However, the present work highlights the studies that used PGPR for the sustainable production of coffee cultivation in Ecuador. It was possible to identify that the most studied and widespread bacteria in the coffee rhizosphere are Rhizobium, Azotobacter, Azospirillum, Acetobacter and Pseudomonas. The performance of these strains depends on the characteristics of competition with natural microorganisms and according to the physicochemical and edaphic conditions of the soil. The use of PGPR allows to reduce the use of fertilizers such as phosphate, nitrogen and fungicides, trying to improve the absorption of nutrients. Greater knowledge of the bacterial characteristics that drive plant growth promotion could motivate and stimulate the development of creative solutions using PGPR in highly changing environmental and climatic settings. | es_ES |

| dc.description.abstract | Las bacterias de vida libre con diversas habilidades relacionadas con el crecimiento y la salud de las plantas han sido denominadas rizobacterias promotoras del crecimiento vegetal (PGPR). Los PGPR promueven el crecimiento de las plantas a través de varios modos de acción, ya sea directa o indirectamente. Los beneficios proporcionados por estas bacterias pueden incluir una mayor disponibilidad de nutrientes, producción de fitohormonas, desarrollo de brotes y raíces, protección contra varios fitopatógenos y reducción de enfermedades. Además, PGPR puede ayudar a las plantas a resistir el estrés abiótico como la salinidad, la sequía y producción de enzimas que desintoxican las plantas de metales pesados. Los PGPR se han convertido en una estrategia importante en la agricultura sostenible, debido a la posibilidad de reducir los fertilizantes y pesticidas sintéticos, promover el crecimiento, la salud de las plantas y mejorar la calidad del suelo. Hay muchos estudios relacionados con PGPR en la literatura. Sin embargo, el presente trabajo destaca los estudios que utilizaron PGPR para la producción sostenible del cultivo de café en el Ecuador. Se determinó que las bacterias más estudiadas y extendidas en la rizosfera del cafeto son Rhizobium, Azotobacter, Azospirillum, Acetobacter y Pseudomonas. El desempeño de estas cepas depende de las características de competencia con los microorganismos naturales y acorde a las condiciones fisicoquímicas y edáficas del suelo. El uso de PGPR permite reducir el uso de fertilizantes como los fosfatados, nitrogenados y fungicidas, tratando de mejorar la absorción de nutrientes. Un mayor conocimiento de las características bacterianas que impulsan la promoción del crecimiento de las plantas podría motivar y estimular el desarrollo de soluciones creativas que utilicen PGPR en entornos ambientales y climatológicos altamente cambiantes. | es_ES |
