The negative impacts of climate change on native forest ecosystems have created challenging conditions for the sustainability natural regeneration. These challenges arise primarily from abiotic stresses that affect early stages tree development. While there is extensive evidence diversity juvenile microbial symbioses in agricultural and fruit crops, a notable lack reports plants. This review aims to summarize critical studies conducted plant-microbe interactions plants highlight main benefits beneficial microorganisms overcoming environmental such as drought, high low temperatures, metal(loid) toxicity, nutrient deficiency, salinity. reviewed consistently demonstrated positive effects plant-microbiota highlighted potential attributes improve plantlet In addition, this discusses managing symbiosis context restoration, including its impact plant responses phytopathogens, promotion uptake, facilitation seedling adaptation, resource exchange through shared hyphal networks, stimulation soil communities, modulation gene protein expression enhance adaptation adverse conditions.
