Fusarium spp. represent an array of sexual life styles: asexual, homothallic, and heterothallic. The recent availability of genomic resources for several Fusarium species has inspired intense research on these organisms, including a better understanding of sporulation. Although studies have clarified the arrangement of the MAT idiomorphs among these species, little is known about the role of MAT genes in sex and fruiting body development. For most Fusarium species, the sexual cycle does not predominate in the field. However, F. graminearum, a homothallic species, relies on sexual development for spore dissemination to host plants. Recent functional studies have revealed genes involved in many aspects of perithecium development in this species. This chapter will focus on morphogenic aspects of sexual development, summarize the function of genes that have been shown to affect development, and speculate about the ecological and evolutionary implications of sexual life styles read more ...
