References(12) Cited-By(1) When oyster mushroom mycelia photoresponse genes responded to blue light, there was an inherent induction period, which lasted until the light stimulation caused up- and downregulation of the genes. The expression levels of the genes were highly dependent on the intensity of blue (470 nm) and green light (525 nm), while far-red (735 nm) and red light (660 nm) did not affect the expression level regardless of the intensity. In addition, when the mycelia were stimulated for 36 h using blue light at 105 μmol m-2 s-1 of photon flux density and then kept in the dark for 4 d, the expression levels of a few downregulated genes became ca. 2.2 to 3 times greater than before irradiation. These findings have the potential to lead to the development of new phototechnology and techniques in which light-emitting diodes are used in the cultivation of edible mushrooms.
