Science Seminar Series: Fungal Mitochondrial Inheritance—from natural population surveys to laboratory investigations and back

Dr. Jianping Xu,
Department of Biology, McMaster University, Ontario


Mitochondria are essential organelles in eukaryotic cells and it’s generally believed that mitochondria are inherited from a single parent, predominantly the maternal parent. However, most studies on mitochondrial inheritance have been on plants and animals.

In this presentation, I will show a diversity of fungal mitochondrial inheritance patterns and describe how they differ from those in plants and animals.

I will describe how an accidental finding from the last century has led us to a journey full of surprises and to identifying a model from which to further test the molecular mechanisms and evolutionary hypotheses about the potential costs and benefits of uniparental and biparental mitochondrial inheritance.
