Halotolerant Endophytic Fungi: Diversity, Host Plants, and Mechanisms in Plant Salt–Alkali Stress Alleviation

Over 1.3 billion hectares of farmland worldwide suffer from excess salt and alkalinity, drastically reducing crop yields. Special fungi that live inside plant tissues can help crops survive in these harsh conditions without harming them. These fungi work by helping plants manage salt accumulation, boost their natural defenses, and produce protective compounds. While laboratory tests show promising results with yield increases up to 40%, practical field application remains challenging due to environmental variables.

Differential hypo-osmotic stress responses and regulatory mechanisms of Aspergillus sydowii in amphipod guts and hadal sediments

Scientists isolated a fungus from the gut of deep-sea amphipods in the Mariana Trench and discovered how it uniquely adapts to low-salt conditions. Unlike other fungal strains from different habitats, this gut fungus showed special abilities to survive and even thrive when salt levels dropped dramatically. The researchers found that the fungus rapidly rewired its genes and cellular structures to maintain water balance and protect itself, revealing how life in extreme deep-sea environments drives evolution of novel survival strategies.
