Our research is directed to understand the signaling roles of reactive oxygen species (ROS), such as H2O2, in cell physiology and differentiation [1-7]. Mitochondria [8] and NADPH oxidase enzymes [9] are the most important sources of ROS in eukaryotic cells and play critical roles in general cell physiology and cell differentiation [1,6,10-12]. A lack of mitochondrial division results in severe growth and developmental defects in the fungus Aspergillus nidulans [11], while imbalances in mitochondrial fusion and fission are related to neurodegenerative diseases, like Alzheimer and Parkinson [15].

We reported that H2O2 induces dramatic changes in mitochondrial morphology [11,17], including mitochondrial constriction, division and outer membrane remodeling, and that constriction and division require mitochondrial depolarization, calcium and the endoplasmic reticulum-mitochondria encounter structure complex [16]. We also identified the dynamin-like protein DnmA and its putative receptor FisA as essential for mitochondrial division and partially required for peroxisome division. The lack of these proteins produces increased mitochondrial ROS levels and notable defects in asexual and sexual differentiation [11].
