Transition from heterothallism to homothallism is hypothesised to have facilitated speciation among emerging Botryosphaeriaceae wheat-pathogens

Thynne, Elisha; McDonald, Megan C; Solomon, Peter S

Description

White grain disorder (WGD) is a recently emerged wheat disease in Australia caused by three Botryosphaeriaceae fungi, from the genus Eutiarosporella. These species are E. tritici-australis, E. darliae, and E. pseudodarliae. Characterisation of the mating type genes for the WGD-species show that the genome sequence of a single E. darliae and E. pseudodarliae isolate both harbour MAT1-2-1 and MAT1-1-1, which suggests that these species are homothallic. However, unlike most other characterised...[Show more]
