Pleurotus tuoliensis is a valuable, rare and edible mushroom that is been commercially cultivated and is rapidly developing in China markets. Low temperatures are required to induces primordia initiation for the successful production of fruiting bodies (basidiomes) during commercial cultivation. In this work, we investigated the enzymatic activities and performed transcription profiling analysis of enzymatic genes under different low temperature conditions. The results suggest that the enzymatic activities and transcription levels decrease or increase significantly at 4 and 13 °C. Lacc10 and mnp6 seems to play a dominant role during nutrition growth. Furthermore, the expression of laccase and peroxidase genes was highly correlated to the detected extracellular enzymatic activity. Cold stress genes expression profiles were upregulated under 4 °C/13 °C (3 days), while only the Hsp70 gene was downregulated (at the stage of fruiting bodies production) at 13 °C (12 days). Our results showed that the transcriptional regulation of laccase and ligninolytic peroxidase genes plays an important role in the fruiting bodies of Bailinggu under low temperature induction (4 °C). Induction at low temperatures was a highly important cultivation condition in Bailinggu.
