A Zn2-Cys6 transcription factor, TgZct4, reprograms antioxidant activity in the fungus Trichoderma guizhouense to defend against oxidative stress

mycolabadmin

Researchers discovered a key protein switch in a beneficial fungus called Trichoderma guizhouense that helps it survive harmful oxidative stress. This fungus is used as a natural pesticide to protect crops from disease. The protein, called TgZct4, acts like a master controller that turns on the fungus’s defense systems when it encounters damaging chemical stress, making it more resilient and effective at protecting plants.

This research identifies a special protein called TgZct4 in a beneficial fungus called Trichoderma guizhouense that helps it survive harmful stress from hydrogen peroxide. When the fungus encounters oxidative stress, TgZct4 quickly activates and switches on genes that produce protective enzymes. This discovery helps scientists understand how this fungus can be such an effective biological pest control agent and could lead to improvements in using it as a natural alternative to chemical pesticides.

Trichoderma guizhouense is a fungus used to protect plants from harmful pathogens. Researchers discovered that a special protein called TgZct4 acts like a master switch that activates the fungus’s defense system against harmful reactive oxygen molecules. When the fungus encounters stress, TgZct4 turns on genes that produce protective enzymes called catalases and superoxide dismutases, helping the fungus survive. This discovery could help scientists create even more effective biological pest control products.

A fungal biocontrol agent called Trichoderma guizhouense uses a special protein called TgZct4 to protect itself from harmful oxidative stress caused by hydrogen peroxide. When the fungus encounters this stress, TgZct4 activates a series of antioxidant enzymes that neutralize the damaging reactive oxygen species. This discovery helps explain how this beneficial fungus can survive and control plant diseases in harsh soil environments, potentially improving its use as an environmentally friendly alternative to chemical pesticides.
