FONPS6, a Nonribosomal Peptide Synthetase, Plays a Crucial Role in Achieving the Full Virulence Potential of the Vascular Wilt Pathogen Fusarium oxysporum f. sp. Niveum

mycolabadmin

This research explores how a specific fungal gene called FoNPS6 helps the watermelon-wilt-causing fungus Fusarium oxysporum attack plants. Scientists deleted this gene and found that mutant fungi were much less aggressive, couldn’t handle stress well, and struggled to penetrate plant roots. When the gene was restored, the fungi regained full virulence. The study reveals that FoNPS6 helps the fungus absorb iron and break down plant defense chemicals.

Gene fusion and functional diversification of P450 genes facilitate thermophilic fungal adaptation to temperature change

mycolabadmin

Researchers discovered that a thermophilic fungus uses two special genes to adapt to temperature changes. One of these genes is uniquely fused from two different genes, creating a hybrid protein with multiple functions. These genes help the fungus produce iron-binding molecules that stabilize its structure and support its growth when temperatures drop, allowing the fungus to survive in environments from compost piles to stored grains.

Iron acquisition in the mutualistic fungus Penicillium herquei: implications of mineral elements in insect-fungus symbiosis

mycolabadmin

A fungus that lives with beetles has evolved special abilities to collect and store iron, which it shares with its insect partner. Researchers found that this mutualistic fungus produces much higher levels of iron than the plant leaves the beetles would normally eat. The fungus uses special proteins and iron-grabbing molecules to accumulate this essential nutrient, providing a nutritional advantage to the beetle and strengthening their partnership.
