Directors Seminar: Sexual Reproduction, Female Fertility and Effective Population Number in Fusarium Populations

Date & time

12.30–1.30pm 27 February 2017


Slatyer Seminar Room, DA Brown Building


Prof John Leslie


Sexual reproduction is a key component of species life cycles.  Sexual reproduction in fungi is subject to a number of different variations, and is different from that in many organisms since sexual role (male or female) may be distinct from or confounded with mating type.  The dual functional roles of asexual propagules, i.e., as spermidia in a sexual cross or to establish physiological distinct colonies, enables non-conventional reproductive strategies, especially when asexual reproduction is preferred to sexual reproduction.  This talk will explore the theoretical implications of such reproductive strategies and discuss some Fusarium populations where relevant variables have been measured/estimated and how observed variations in population structure may provide insights into the origins, establishment and current reproductive strategies in some of these fungi.
