Oxidative stress and differentiation in Neurospora crassa
- 196 Downloads
Environmental stress factors induce oxidative stress in fungi by increasing the intracellular concentrations of reactive oxygen species (ROS). In the mycelium, ROS act as signal molecules needed for cytodifferentiation at certain stages of the development of fungi. Generation of ROS in cells induces the activation of antioxidant protective mechanisms. The purpose of this communication is to analyze the role of ROS in light signal transduction, mediated in Neurospora crassa cells by the White Collar Complex.
