description |
The population dynamics of the human race has led to the exploitation of natural resources in search of a way to meet the nutritional needs of the billions of people inhabiting the planet. This need has led to the use of high-efficiency materials in agriculture, plant varieties with shorter production cycles that are also resistant to pests and diseases, and chemicals that provide protection against biotic factors (pests and disease), additionally the nutrients required to grow plants. However, the strategies used in modern agriculture have led to negative environmental impacts that we have yet to fully understand. Groundwater contamination, eutrophication, increased greenhouse gases, and the accumulation of toxic substances in the food chain are some of the serious problems that have arisen worldwide due to the indiscriminate use of agrochemicals. As an alternative to the use of these substances, the use of rhizopheric bacteria has been proposed owing to its known action as plant growthpromoting bacteria (PGPB). These bacteria are able to stimulate plant growth directly and indirectly and have several complex mechanisms that interact with each other to establish beneficial relationships, especially with the roots of target plants. The study and understanding of PGPR have been the subjects of great importance in many studies at a global level. This review, therefore, aims to better understand the mechanisms of plant growth-promoting rhizobacteria on plant development and their role in nutrient cycling. |

La dinámica poblacional de la especie humana ha llevado a que la explotación de los recursos naturales, en búsqueda de suplir las necesidades alimenticias de los miles de millones de personas que habitan el planeta. Esta necesidad ha llevado a la utilización de materiales de alta eficiencia en la agricultura, variedades vegetales resistentes a plagas y enfermedades con ciclos de producción más cortos, agroquímicos que surten las necesidades nutricionales y provean protección frente factores bióticos adversos (plagas y enfermedades). Sin embargo, estas estrategias utilizadas en la agricultura moderna han generado impactos ambientales negativos que aún no comprendemos. La contaminación de aguas freáticas, eutrofización, aumento de gases de invernadero y acumulación de sustancias toxicas en la cadena trófica, son algunos de los graves problemas que se presentan por el uso indiscriminado de agroquímicos. Como alternativa a la utilización de estas sustancias, se ha propuesto el uso de bacterias rizosféricas que tienen reconocida acción sobre el crecimiento y desarrollo vegetal (PGPR, por sus siglas en ingles). Estas bacterias son capaces de estimular el desarrollo de las plantas de manera directa e indirecta y poseen una serie de mecanismos complejos que interactúan entre sí para establecer relaciones benéficas, especialmente con las raíces de las plantas objetivo. El estudio y entendimiento de las PGPR han sido temas de gran importancia en muchas investigaciones a nivel mundial, por esta razón esta revisión tiene por objetivo hacer una revisión parcial para dar a conocer los mecanismos que poseen las rizobacterias promotoras del crecimiento vegetal en el desarrollo de las plantas, así como el papel que desempeñan en el ciclaje de nutrientes. 2018-11-06T20:41:27Z 2018-11-06T20:41:27Z 2011 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revista.corpoica.org.co/index.php/revista/article/view/227 10.21930/rcta.vol12_num2_art:227 http://hdl.handle.net/20.500.12324/33888 reponame:Biblioteca Digital Agropecuaria de Colombia repourl:https://repository.agrosavia.co instname:Corporación colombiana de investigación agropecuaria AGROSAVIA spa http://revista.corpoica.org.co/index.php/revista/article/view/227/233 application/pdf Colombia Corporación Colombiana de Investigación Agropecuaria (Agrosavia) Mosquera (Colombia) Corpoica Ciencia y Tecnología Agropecuaria; Vol 12 No 2 (2011); 159-166 Corpoica Ciencia y Tecnología Agropecuaria; Vol. 12 Núm. 2 (2011); 159-166 revista Corpoica Ciência e Tecnologia Agropecuária; v. 12 n. 2 (2011); 159-166 2500-5308 0122-8706 10.21930/rcta.vol12-num2 |
