Organisms have developed different features to capture or sense sunlight. Vertebrates evolved specialized organs (eyes) which contain a variety of photosensor cells that help them see the light aid orientation. Opsins are major photoreceptors found in vertebrate eye. Fungi, with more than five million estimated members, represent an important clade living organisms functions for sustainability life on our planet. Light signalling regulates range developmental and metabolic processes including asexual sporulation, sexual fruit body formation, pigment carotenoid production even secondary metabolites. Fungi adopted three groups photoreceptors: (I) blue receptors, White Collars, vivid, cryptochromes, F proteins DNA photolyases, (II) red sensors, phytochromes (III) green sensors microbial rhodopsins. Most mechanistic data were elucidated roles Collar Complex (WCC) fungal kingdom. The WCC acts as both photoreceptor transcription factor by binding target genes, whereas phytochrome initiates cascade using mitogen-activated protein kinases elicit its cellular responses. Although mechanism photoreception has been studied great detail, not compared vision. Therefore, this review will mainly focus findings derived from two model organisms, namely Aspergillus nidulans Neurospora crassa comparison some mechanisms Our be way is translated into changes gene expression, influences morphogenesis metabolism fungi.

Genome-wide analyses of light-regulated genes in Aspergillus nidulans reveal a complex interplay between different photoreceptors and novel photoreceptor functions

Fungi sense light of different wavelengths using blue-, green-, and red-light photoreceptors. Blue sensing requires the "white-collar" proteins with flavin as chromophore, red is sensed through phytochrome. Here we analyzed genome-wide gene expression changes caused by short-term, low-light intensity illumination red- or far-red in Aspergillus nidulans found that more than 1100 genes were differentially regulated. The largest number up- downregulated depended on phytochrome FphA attached HOG pathway. white-collar orthologue LreA fulfill activating but also repressing functions under all conditions both appear to have roles dark. Additionally, about 100 genes, which are induced absence phytochrome, suggesting alternative systems. We blue-light receptor LreA. present evidence cryptochrome may be part this regulatory cue, essential for response. In addition vivo data showing involved sensing, performed spectroscopy purified show it responds indeed blue light.
