A Single Transcription Factor (PDD1) Determines Development and Yield of Winter Mushroom (Flammulina velutipes).

ABSTRACT: Most of the edible mushrooms cannot be cultivated or have low yield under industrial conditions, partially due to the lack of knowledge on how basidioma (fruiting body) development is regulated. From winter mushroom (Flammulina velutipes), one of the most popular industrially cultivated mushrooms, a transcription factor, PDD1, with a high-mobility group (HMG)-box domain was identified based on its increased transcription during basidioma development. pdd1 knockdown by RNA interference affected vegetative growth and dramatically impaired basidioma development. A strain with an 89.9% reduction in the level of pdd1 transcription failed to produce primordia, while overexpression of pdd1 promoted basidioma development. When the transcriptional level of pdd1 wa
