Fusarium crown rot (FCR) is a soil-borne disease devastating common wheat yields. This study identifies a novel 18.6 kDa heat shock protein (TaHSP18.6) and its interplay with lysine deacetylase (TaSRT1) in conferring FCR resistance by modulating auxin levels. Overexpression and genetic mutations reveal TaHSP18.6’s role, highlighting a potential pathway for enhanced wheat resilience.

Discoveries in the Phaeoclavulina genus, known for its ramarioid fungi, have revealed greater diversity in southern South America's temperate-tropical zones than previously recognized. This study identifies eight taxa in Argentina, including four new species, and proposes neotypification for P. camellia, underscoring the region's underestimated fungal richness.

Ectomycorrhiza, a mutualistic relationship between fungi and plants, enhances plant growth and stress resistance. This review explores fungal-produced symbiotic regulators, such as plant hormones and small proteins, crucial for ectomycorrhizal development. Recent insights into these regulators aim to deepen understanding of their role in symbiosis establishment, offering new research directions.

Ability of non-aflatoxigenic Aspergillus section Flavi strains to grow in the presence of herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) and remove it from synthetic wastewater.

The study explores non-aflatoxigenic Aspergillus section Flavi's potential for bioremediation of 2,4-D, a common herbicide. Four A. oryzae strains, suited to grow at 25°C and pH 7, removed 40-60% of 2,4-D from synthetic wastewater. These findings suggest their viability for bioaugmentation in reducing environmental contamination by 2,4-D.
