  • Title: Light-induced synchronous conidiation in the fungus Botrytis cinerea.
    Author: Tan KK.
    Journal: J Gen Microbiol; 1976 Apr; 93(2):278-82. PubMed ID: 945324.
    Abstract:
    Botrytis cinerea Pers. ex Fr. in stationary liquid cultures conidiated asynchronously in darkness after 4 days' growth. Synchronous conidiation was induced by irradiating dark-grown cultures with near-ultraviolet light for 12 h. The number of conidia increased very rapidly 10 h after the end of the photo-induction period, and conidiation was completed by the 14th hour. Filter paper cultures of the fungus also showed synchronous conidiation upon irradiation with near-ultraviolet light, but the rapid increase in the number of conidia took place 2 h earlier, conidiation being completed by the 12th hour. Cultures irradiated with blue light, however, produced sterile mycelia and showed complete suppression of conidiation.
