Estrategias para mejorar la tolerancia a estreses abióticos de la simbiosis Rhizobium-leguminosa

Abstract

[ES] Los estreses abióticos afectan negativamente al rendimiento de las leguminosas principalmente en suelos pobres en nitrógeno. Esto se debe a que la simbiosis Rhizobium-leguminosa y la fijación simbiótica de nitrógeno son altamente sensibles a dichos estreses. Es posible utilizar diferentes estrategias para dotar a las leguminosas de una mayor tolerancia a los estreses abióticos. Una de ellas es su transformación con genes codificadores de enzimas que acentúan la acumulación de osmolitos, lo que en algunos casos ha permitido aumentar la tolerancia de las plantas a estreses salino o hídrico. Otra es la de transformar plantas o rizobios para mejorar sus sistemas de defensa contra las especies reactivas de oxígeno, lo que también ha permitido aumentar su resistencia a los estreses ambientales y retrasar la senescencia de los nódulos. El estudio del papel de los factores de transcripción en las respuestas de las plantas a diversos estreses está adquiriendo gran importancia, por lo que su manipulación para la obtención de leguminosas tolerantes a estreses abióticos puede ser una estrategia de gran relevancia en un futuro próximo.

[EN] Abiotic stresses adversely affect legume yield, mostly in nitrogen-deficient soils, as Rhizobium-legume symbioses and symbiotic nitrogen fixation are extremely sensitive to such stresses. Several strategies are being used to increase stress tolerance in legumes, such as transformation with genes coding for enzymes that enhance osmolyte accumulation, which in some cases has led to increased tolerance of plants to salt or water stress. Transformation of plants or rhizobia to improve their reactive oxygen species-quenching systems has also been shown to increase their resistance to environmental stresses and to delay nodule senescence. Currently, researchers are giving importance to the role of transcription factors in the responses of plants to various stresses and their manipulation may be an important strategy for obtaining legumes with increased tolerance to abiotic stresses in the coming future.
