| ophiostoma mitovirus 3a , ascorbic acid, glutathione, and photoperiod affect the development of stromata and apothecia by sclerotinia homoeocarpa. | hypovirulence in sclerotinia homoeocarpa is associated with infection by ophiostoma mitovirus 3a (omv3a). omv3a is also present in asymptomatic isolates, with growth and virulence comparable to that of virus-free isolates. hypovirulent isolates have impaired mitochondrial function resulting in increased activity of the alternative oxidase pathway, which is implicated in the reduction of reactive oxygen species in other fungi. in this study, hypovirulent, asymptomatic, and virus-free isolates wer ... | 2011 | 21539495 |
