Light sensing and responses in fungi

Combined Effect of Light and Nutrients on the Micromorphology of the White rot Fungus Cerrena unicolor

“…It can be considered crucial for successful competition and survival in nature. Fungi use light as a source of information about the surrounding environment [1]. These microorganisms are equipped with several photosensory systems and can respond to different light intensities and colors [1][2][3].…”

“…Fungi use light as a source of information about the surrounding environment [1]. These microorganisms are equipped with several photosensory systems and can respond to different light intensities and colors [1][2][3]. For the perception of light, fungi employ various mechanisms comprising flavin-based blue-light sensors, retinal-based green-light sensors (such as rhodopsin), and linear tetrapyrrole-based red-light sensors, which suggests that they can detect specific wavelengths by discrete photoreceptory proteins [3].…”

The Trichoderma atroviride Strains P1 and IMI 206040 Differ in Their Light-Response and VOC Production

“…In T. atroviride, these volatiles are increasingly produced by conidiating cultures and were described to act as elicitors of conidiation [18]. In addition, 1-octen-3-ol production by T. atroviride was up-regulated upon treatment of the fungus with the Fusarium-derived mycotoxin fusaric acid, while levels of other VOCs such as 6PP, alpha-phellandrene, and beta-phellandrene decreased [16].Light, especially in the UV/blue spectrum, is an important environmental cue that triggers asexual reproduction in many fungal species [19]. In Trichoderma, most studies on photoconidiation have been performed with T. atroviride strain IMI 206040 as a model [20][21][22][23][24][25][26].…”

A fotobiologia de Metarhizium acridum: qualidade de luz, tolerância ao estresse e regulação gênica

“…Visible light (400-700 nm) is perhaps the most important environmental signal for many fungi as it regulates a variety of biological processes such as the balance between sexual and asexual development, spore germination, vegetative growth, secondary metabolism, circadian time keeping, phototropism, pathogenicity, nutrient uptake, and stress tolerance (Yu and Fischer, 2019). Visible radiation is made of photons of different wavelengths and fungi possess a range of photoreceptors that sense distinct spectral colors ( Fig.…”
