Descripción
Symbiotic nitrogen fixation (SNF) is one of the main pathways for nitrogen entry in the biosphere and a likely alternative to the overuse of polluting and expensive synthetic fertilizers. Its principal form is the symbiosis between legumes and a group of bacteria known as rhizobia. After a complex process triggered by bacterial and plant signals, new organs, the root nodules, are developed. These rhizobia differentiate into bacteroids surrounded by the plant-derived symbiosome membrane, and are able to convert, fix, N2 into NH4 +. As in other endosymbiotic relationships, there is an intense nutrient trafficking between the symbionts (Udvardi and Poole, 2013). The ammonia fixed by bacteroids is transferred to the host plant through the symbiosome membrane, in exchange for photosynthates and mineral nutrients (phosphate, sulfur, iron, zinc?) provided by the plant (González-Guerrero et al. 2014; 2016). In spite of the importance that zinc has on SNF, it currently remains unknown how this micronutrient is delivered to nitrogen fixing organs, and its function therein. It has been proposed that zinc should be transported through vascular bundles to the aposplast of the apical zone of the nodule, where a zinc transporter located at the plasma membrane of infected cells would mediate the acquistion of zinc for nitrogen fixation (González-Guerrero et al. 2014; 2016).
