Resumen:

Sunlight, harvested by photosynthetic organisms (plants, algae, and some bacteria) and used to synthesize energy-rich molecules (sugars) from carbon dioxide and water, provides the energy required to sustain life on Earth. In addition, sunlight properties such as intensity, duration, polarization, and spectral composition are used as sources of information (1). Indeed, all forms of life are continuously obtaining and decoding information from their environment. In fungi sunlight, ranging from ultraviolet (UV) to infrared wavelengths, regulates a diversity of biological processes including circadian rhythms, morphogenesis, tropism, and synthesis of pigments, among others (reviewed in reference 1). UV light can be harmful, since DNA modification products of photochemical reactions may be transmitted to the next generation as a mutation. Visible light appears not only to provide early warning of the presence of impending UV radiation and further damage, but also seems to contribute to the capacity of these organisms to deal with abiotic stress in general (2 - 5). Thus, the ability of most fungi to perceive and respond to light has very likely contributed to their survival and fitness. © 2018 American Society for Microbiology. All rights reserved.
