Resumo(s)
Colletotrichum spp. infect a wide diversity of hosts, causing plant diseases on many
economically important crops worldwide. The genus contains approximately 189
species organized into at least 11 major phylogenetic lineages, also known as species
complexes. The Colletotrichum acutatum species complex is a diverse yet relatively
closely related group of plant pathogenic fungi within this genus. Within the species
complex we find a wide diversity of important traits such as host range and host
preference, mode of reproduction and differences in the strategy used to infect their
hosts. Research on fungal comparative genomics have attempted to find correlations
in these traits and patterns of gene family evolution but such studies typically compare
fungi from different genera or even different fungal Orders. The C. acutatum species
complex contains most of this diversity within a group of relatively closely related
species. This Perspective article presents a review of the current knowledge on
C. acutatum phylogeny, biology, and pathology. It also demonstrates the suitability of
C. acutatum for the study of gene family evolution on a fine scale to uncover evolutionary
events in the genome that are associated with the evolution of phenotypic characters
important for host interactions.
