Abstract
Blue light is an important environmental factor that induces mushroom growth and morphological changes. In this study, after confirming the morphological difference between Lentinula edodes (LE) under blue light condition (BL) and lightless condition (LL), the increase and decrease in LE protein and the expression of RNA of each protein were confirmed under each condition. LE specimens grown in BL and LL were identified by 253 spots in BL through 2D electrophoresis and LC-MSMS analysis, and 22 types of proteins were identified. It was confirmed that 14 types of proteins showed reduced expression in BL compared to LL. On the other hand, eight kinds of proteins with increased expression in blue light compared to LL were identified. As a result of confirming the difference from the expression pattern in 2D electrophoresis through Quantitative Real-Time PCR, it was confirmed that the expression pattern of the two proteins showed a difference. Therefore, this study will be a key study on the changes in mushroom morphology induced by blue light and the proteins that induce it.
Highlights
Lentinula edodes (LE) is a mushroom belonging to Basidiomycota, Marasmiaceae and Lentinula, and its area and production are increasing in Northeast Asia [1]
The expression patterns of all proteins were compared through 2D electrophoresis method to confirm the morphological characteristics of LE fruit bodies grown in blue light and lightless conditions and various protein patterns related to LE
The results show that the pilus diameter is increased to 41.17 am in the blue light condition (BL) condition and 28.42 bm in the lightless condition (LL) condition and the pilus diameter increases in the BL condition
Summary
Lentinula edodes (LE) is a mushroom belonging to Basidiomycota, Marasmiaceae and Lentinula, and its area and production are increasing in Northeast Asia [1]. LE mushrooms have a unique flavor and taste and are mainly used for food in Northeast Asia, and have been known to have functional effects such as hypertension and arteriosclerosis [2]. Light acts as an important environmental signal that regulates the growth and morphogenesis of organic matter and produces secondary metabolites. Phytochromes, a red and far-red light receptor, and cryptochromes, a blue light receptor, are known to participate in the regulation of growth and morphogenesis. The expression patterns of all proteins were compared through 2D electrophoresis method to confirm the morphological characteristics of LE fruit bodies grown in blue light and lightless conditions and various protein patterns related to LE. Proteins that influence photoreaction and morphological properties were investigated through PCR method
