Abstract

The selection of rhizobia for soybean is a sustainable strategy to increase the yield of this crop. The aim of this study was to investigate the efficiency of Bradyrhizobiumstrains for nitrogen fixation and modulation of physiological parameters and grain production in inoculated soybean genotypes. The experiment was carried out with three soybean genotypes (M8349 IPRO, M8372 IPRO, and Bônus 8579 RSF) and six nitrogen (N) sources (UFLA06-19, UFLA06-22, UFLA06-24, a commercial inoculant, and two controls without inoculation (without and with nitrogen)). The UFLA strains increased nitrogen accumulation in the shoots of the M8372 IPRO genotype and modulated photosynthetic pigments and soluble carbohydrates contents in symbiosis with the M8349 IPRO genotype. Strains UFLA06-22 and UFLA06-24 were efficient in grain nitrogen accumulation in genotypes M8372 IPRO and M8349 IPRO. Principal component analysis shows the close positioning of several parameters in soybean genotypes inoculated with these strains. Our results demonstrate the potential of strains UFLA06-22 and UFLA06-24 for sustainable soybean production.

Abstract

NH4+ nutrition has emerged as an effective approach to generate salt tolerance in sorghum plants. Our hypothesis was that salt-tolerance mechanisms in NH4+-grown sorghum are related to rapid absorption and assimilation of NH4+ as well as favorable K+ uptake. Sorghum plants were grown in nutrient solutions containing NO3− or NH4+ and subjected to NaCl at 75 mM. Under control conditions, K+ uptake was more pronounced in NO3− than that of NH4+-fed plants. Under salinity, NH4+-grown plants showed lower Na+ and higher K+ contents than NO3–grown plants at 1 and 10 days after salt exposure, and thereby increased K+/Na+ ratio. The data indicate that NH4+ does not increase K+ uptake under salt stress conditions, but decrease the K+ efflux and maintain an elevated K+/Na+ ratio in tissues. In parallel, sorghum plants displayed elevated NH4+ uptake, evidenced by higher Vmax for NH4+, assimilating a higher amount of NH4+ into amino acids in roots; whereas NO3−-fed plants accumulated NH4+ in the shoot. In conclusion, NH4+-fed salt-stressed sorghum plants maintain favorable K+/Na+ homeostasis due to greater retention of K+ in tissues together with restricting control of Na+ accumulation and transport. S. bicolor face to NH4+ toxicity by activating mechanisms for rapid inorganic N-assimilation. [ABSTRACT FROM AUTHOR]
