Nodule Synthetic Bacterial Community as Legume Biofertilizer under Abiotic Stress in Estuarine Soils.

Estuaries are ecologically important ecosystems particularly affected by climate change and human activities. Our interest is focused on the use of legumes to fight against the degradation of estuarine soils and loss of fertility under adverse conditions. This work was aimed to determine the potenti...

Our interest is focused on the use of legumes to fight against the degradation of estuarine soils and loss of fertility under adverse conditions. This work was aimed to determine the potential of a nodule synthetic bacterial community (SynCom), including two Ensifer sp. and two Pseudomonas sp. strains isolated from Medicago spp. nodules, to promote M. sativa growth and nodulation in degraded estuarine soils under several abiotic stresses, including high metal contamination, salinity, drought and high temperature. These plant growth promoting (PGP) endophytes were able to maintain and even increase their PGP properties in the presence of metals. Inoculation with the SynCom in pots containing soil enhanced plant growth parameters (from 3- to 12-fold increase in dry weight), nodulation (from 1.5- to 3-fold increase in nodules number), photosynthesis and nitrogen content (up to 4-fold under metal stress) under all the controlled conditions tested. The increase in plant antioxidant enzymatic activities seems to be a common and important mechanism of plant protection induced by the SynCom under abiotic stress conditions. The SynCom increased M. sativa metals accumulation in roots, with low levels of metals translocation to shoots. Results indicated that the SynCom used in this work is an appropriate ecological and safe tool to improve Medicago growth and adaptation to degraded estuarine soils under climate change conditions.MCIN/AEI/UE NextGenerationEU/PRTR PDC2021-120951-I00Junta de Andalucía, I+D+I FEDER - US-1262036Plan Andaluz de Investigación, Desarrollo e Innovación de la Junta de Andalucía - PAIDI2020 - P20_00682MDPIBiología Vegetal y EcologíaMicrobiología y ParasitologíaMinisterio de Ciencia e Innovación (MICIN).
