Light in the Fungal World: From Photoreception to Gene Transcription and Beyond

Annual Review of Genetics, Journal Year: 2019, Volume and Issue: 53(1), P. 149 - 170

Published: Aug. 27, 2019

Fungi see light of different colors by using photoreceptors such as the White Collar proteins and cryptochromes for blue light, opsins green phytochromes red light. Light regulates fungal development, promotes accumulation protective pigments proteins, tropic growth. The complex (WCC) is a photoreceptor transcription factor that responsible regulating after exposure to In Neurospora crassa, interaction WCCs their binding promoters activate transcription. Aspergillus nidulans, WCC phytochrome interact coordinate gene other responses, but contribution these photobiology varies across species. Ultimately, effect on biology result coordinated transcriptional regulation activation signal transduction pathways.

Current progress on pathogenicity‐related transcription factors in Fusarium oxysporum

Molecular Plant Pathology, Journal Year: 2021, Volume and Issue: 22(7), P. 882 - 895

Published: May 9, 2021

Abstract Fusarium oxysporum is a well‐known soilborne plant pathogen that causes severe vascular wilt in economically important crops worldwide. During the infection process, F . not only secretes various virulence factors, such as cell wall‐degrading enzymes (CWDEs), effectors, and mycotoxins, potentially play roles fungal pathogenicity but it must also respond to extrinsic abiotic stresses from environment host. Over 700 transcription factors (TFs) have been predicted genome of F. oxysporum, 26 TFs functionally characterized formae speciales Among these TFs, total 23 belonging 10 families are required for pathogenesis through mechanisms pathways, zinc finger TF family largest among families, which consists 15 In this review, we report current research progress on analysed sort them into four groups based their pathogenicity. Furthermore, summarize compare biofunctions, involved putative targets, homologs analyse relationships them. This review provides systematic analysis regulation virulence‐related genes facilitates further mechanistic virulence.

Red- and Blue-Light Sensing in the Plant Pathogen Alternaria alternata Depends on Phytochrome and the White-Collar Protein LreA

mBio, Journal Year: 2019, Volume and Issue: 10(2)

Published: April 8, 2019

Light controls many processes in filamentous fungi. The study of light regulation a number model organisms revealed an unexpected complexity. Although the molecular components for sensing appear to be widely conserved fungal genomes, regulatory circuits and sensitivity certain species toward specific wavelengths seem different. In N. crassa , most responses are triggered by blue light, whereas A. nidulans red plays dominant role. Alternaria alternata both important. photoreceptors control morphogenetic pathways, homeostasis reactive oxygen species, production secondary metabolites. On other hand, high-osmolarity required FphA LreA, indicating sophisticated cross talk between stress signaling.

Salicylic acid is a phenolic phytohormone which controls plant growth and development. A methyl ester (MSA) derivative thereof volatile involved in plant-insect or plant-plant communication. Here we show that the nematode-trapping fungus Duddingtonia flagrans uses methyl-salicylic isomer, 6-MSA as morphogen for spatiotemporal control of trap formation chemoattractant to lure Caenorhabditis elegans into fungal colonies. product polyketide synthase an intermediate biosynthesis arthrosporols.
