Microbial consortia and their metabolic modulations as mechanisms of water deficit tolerance in strawberry plants

Introduction: One effective and ecologically sustainable strategy that has emerged to enhance plant resilience to water deficits induced by drought stress is the application of plant growth-promoting microorganisms (PGPM). Despite this progress, there remains a lack of clarity in identifying the most effective microbial consortia and understanding the nutritional and metabolic processes that contribute to the drought resilience of strawberry crops.Methods: Two effective microbial consortia were selected based on previous data: CS1 (Claroideoglomus claroideum + Naganishia albida + Paraburkholderia caledonica) and CS2 (Funneliformis mosseae + Candida guillermondii + Bacillus tequilensis) used for drought stress mitigation in plants. These were tested under two irrigation scenarios–well-watered and water-limited conditions, corresponding to 85% and 30% of their water holding capacity (WHC), respectively.Results: The co-inoculation of the CS1 consortium increased SDW by 38.23% compared to the control and 52.94% compared to CS2. Likewise, this consortium increased the concentrations of N, P, and K by 24.3%, 6.4%, and 25.7%, respectively, compared to the WS control. Finally, CS1 mitigated phytotoxic effects by activating flavonoid-type, fatty acids, and phenolic acid metabolites, as well as growth-regulating hormones, compared to the CS2 consortium and control plants, whose changes in specialized metabolism did not allow them to tolerate stress.Discussion: This study elucidated the molecular mechanisms by which microbial biostimulants increase drought tolerance.

Osmoprotective Microbial Resources in High Ecological Value Ecosystems: Characterization and Application to Complement Rhizosphere Microbiomes and Enhance Crops in the Coastal Drylands from Central Chile.

El objetivo principal de este proyecto busca integrar las características ecológicas, funcionales y microbiológicas de microorganismos rizosféricos nativos adaptados a la sequía en formaciones naturales de alto valor ecológico, como base para desarrollar bioinsumos que contribuyan a mejorar la resiliencia y productividad de los cultivos en las zonas áridas del secano costero de Chile central.
