Interactions between light and conidiation through transcriptional regulation in Botrytis by the Schumacher lab

Regulation of conidiation in Botrytis cinerea involves the light-responsive transcriptional regulators BcLTF3 and BcREG1 Botrytis cinerea is a plant pathogenic fungus with a broad host range. Due to its rapid growth and reproduction by asexual spores (conidia), which increases the inoculum pressure, the fungus is a seri

Role for SUB1 in sexual development and secondary metabolism in Trichoderma by the Schmoll group in Mol Microbiol

SUB1 has photoreceptor dependent and independent functions in sexual development and secondary metabolism in Trichoderma reesei Light dependent processes are involved in the regulation of growth, development and enzyme production in Trichoderma reesei. The photoreceptors BLR1, BLR2 and ENV1 exert crucial functions in these processes....

A nice review on light sensing in the plant pathogen Botrytis.

How light affects the life of Botrytis - ScienceDirect Fungi, like other organisms, actively sense the environmental light conditions in order to drive adaptive responses, including protective mechanisms against the light-associated stresses, and to regulate development. Ecological niches are characterized by different light regimes, for instance light…

A role for a Velvet interacting protein in light regulation in Aspergillus by the Fischer lab.
http://onlinelibrary.wiley.com/doi/10.1111/mmi.13739/full

The Aspergillus nidulans Velvet‐interacting protein, VipA, is involved in light‐stimulated heme biosynthesis Filamentous fungi are able to differentiate morphologically and adapt the metabolism to internal and external cues. One major regulator is the so‐called velvet protein, VeA, best studied in Aspergillus...

Sensing light by yeast uncovered:
http://www.nature.com/articles/ncomms14791

Light-sensing via hydrogen peroxide and a peroxiredoxin While yeasts lack dedicated photoreceptors, they nonetheless possess metabolic rhythms responsive to light. Here the authors find that light signalling in budding yeast involves the production of H2O2, which in turn regulates protein kinase A through a peroxiredoxin-thioredoxin redox relay.

Identification of phototropism gene madC in Phycomyces as a regulator or Ras.
http://www.nature.com/articles/srep44790

A Ras GTPase associated protein is involved in the phototropic and circadian photobiology responses in fungi Light is an environmental signal perceived by most eukaryotic organisms and that can have major impacts on their growth and development. The MadC protein in the fungus Phycomyces blakesleeanus (Mucoromycotina) has been postulated to form part of the photosensory input for phototropism of the fruitin...

Targets of the transcription factor ADV-1 in N. crassa connect light and clock regulation with development
http://www.g3journal.org/content/7/1/129.full -1

Next Section Abstract Light and the circadian clock have a profound effect on the biology of organisms through the regulation of large sets of genes. Toward understanding how light and the circadian clock regulate gene expression, we used... -... Circadian clocks, comprised of molecular oscillators, provide a mechanism for organisms to coordinate their physiology and behavior with daily environmental cycles, and to maintain internal temporal order (Bell-Pedersen et al. 2005). External cues, particularly light signals, entrain clocks to 24-hr...

An interesting review of photoreceptor regulation by protein interactions (including WC in fungi!)
http://science.sciencemag.org/content/354/6310/282?utm_campaign=toc_sci-mag_2016-10-20&et_rid=34819577&et_cid=914316

A photoreceptor's on-off switch Photoreceptors are present in all kingdoms of life. They fulfill a broad range of functions, including vision, photoprotection, and regulating growth and development ( 1 ). To maintain photosensitivity, photoreceptor-mediated signaling must be turned on and off in a timely fashion. For example, the…

Regulating the activity of Arabidopsis cryptochrome 2 by protein interactions
http://science.sciencemag.org/content/354/6310/343

Photoactivation and inactivation of Arabidopsis cryptochrome 2 In plants, blue light is perceived by cryptochromes, which, once activated, set off signaling events that regulate gene expression, circadian rhythms, and photomorphogenesis. Wang et al. now show that in the model plant Arabidopsis , one of the functions of activated cryptochromes, which are dimers…

A role for the repressor RCO-1 in circadian gene expression in . Genetics by Luis Larrondo et al
http://www.genetics.org/content/204/1/163?etoc

Modulation of Circadian Gene Expression and Metabolic Compensation by the RCO-1 Corepressor of Neurospora crassa Neurospora crassa is a model organism for the study of circadian clocks, molecular machineries that confer ∼24-hr rhythms to different processes at the cellular and organismal levels. The FREQUENCY (FRQ) protein is a central component of the Neurospora core clock, a transcription/translation negativ...

http://science.sciencemag.org/content/353/6299/541.full

How do sunflowers follow the Sun—and to what end? A field of domesticated sunflowers ( Helianthus annuus ) fully in bloom is a striking sight. The large and showy flowering heads face east, positioned toward the rising Sun. Before floral development, however, elongating vegetative stems move their apices steadily from facing east in the morning to…

Fungal Evolution: Mucor and Phycomyces See Double Newly available genome sequences of two Mucoralean fungi, Phycomyces blakesleeanus and Mucor circinelloides, provide evidence for an ancient whole-genome duplication that contributed to the generation of expanded gene families. These fungi have robust responses to light that can be correlated with t...
