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

Abstract

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.
