Fungal Endophytes Enhance Wheat and Tomato Drought Tolerance in Terms of Plant Growth and Biochemical Parameters
Drought is a major threat to plant growth in many parts of the world. During periods of drought, multiple aspects of plant physiology are negatively affected. For instance, water shortages induce osmotic imbalance, inhibit photosynthesis, decrease nutrient uptake, and increases the production of reactive oxygen species (ROS). In this context, it is necessary to develop sustainable strategies for crops that would help mitigate these conditions. In previous studies, endophytic Zopfiella erostrata strains were found to extensively colonize plant roots, forming a profuse melanized mycelium in the rhizosphere, which could be involved in improving water uptake and nutrient mineralization in plants. The aim of this study is to evaluate the effect of different strains of Z. erostrata on stress mitigation in wheat and tomato plants grown under water deficit conditions. General plant growth variables, as well as physiological and biochemical parameters, related to oxidative status were determined. Our data demonstrate that inoculation with both Zopfiella strains had a very significant effect on plant growth, even under water deficit conditions. However, we observed an even more pronounced impact, depending on the plant and strain involved, suggesting a certain degree of plant/strain compatibility. The biochemical aspects, the accumulation of proline, the oxidative damage to lipids, and the activity of antioxidant enzymes varied considerably depending on the endophyte and the plant evaluated.

Crop residues and agro-industrial by-products from the province of La Rioja (Argentina) suitable for oyster mushroom culture
En la provincia de La Rioja se generan anualmente grandes cantidades de biomasa residual lignocelulósica. Nosotros realizamos un relevamiento para identificar los residuos y subproductos agroindustriales de la provincia, aptos como sustrato para el cultivo de hongos ostra. Caracterizamos su composición morfológica y estimamos la masa que generan anualmente. Determinamos la disponibilidad de la biomasa, evaluando su procesamiento, distribución, estacionalidad, costo y otros usos que compiten con su aplicación como sustrato. Se identificaron ocho cultivos residuales y ocho subproductos agroindustriales, siendo los más abundantes el olivo y el orujo de uva, seguidos de la poda de uva, y la hojarasca de olivo y jojoba. Estos dos últimos junto con el salvado de Prosopis y el hueso de aceituna, no registraron uso como sustrato para la producción de hongos. En ensayos de eficiencia biológica (BE) con cepas comerciales de Pleurotus registramos BE que van en un rango de 28% a 72% según el sustrato y la especie fúngica. En un contexto de déficit en la producción de alimentos de alta calidad y problemas nutricionales asociados a esto, La Rioja tiene un interesante potencial para introducir la producción y consumo de hongos ostra como una solución factible para el abastecimiento alimentario regional.
