Description

Light is one of the constant abiotic factors on the planet and practically all living organisms present some type of response to the light stimulus. An important aspect after light reception is the gene modulation; this mechanism involves stimulating or inhibiting the expression of certain genes that, possibly, have the purpose of adaptation to different environmental conditions. In fungi, light response has a very important effect on the genes involved in circadian regulation; in this process, the products of the frq and frh genes regulate the activity of the White-Collar Complex (WCC) in a time-dependent manner.
