Relation between CarS expression and activation of carotenogenesis by stress in Fusarium fujikuroi
(Frontiers Media S.A., 2022)
Fusarium fujikuroi, a model organism for secondary metabolism in fungi, produces carotenoids, terpenoid pigments with antioxidant activity. Previous results indicate that carotenoid synthesis in F. fujikuroi is stimulated ...

Use of chitin and chitosan to produce new chitooligosaccharides by chitinase Chit42: enzymatic activity and structural basis of protein specificity
(BioMed Central, 2018)
Background Chitinases are ubiquitous enzymes that have gained a recent biotechnological attention due to their ability to transform biological waste from chitin into valued chito-oligomers with wide agricultural, ...

Fungal Secondary Metabolism
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Definition: Fungal secondary metabolites (SMs) comprise a vast collection of compounds expendable for these organisms under laboratory conditions. They exhibit enormous chemical diversity, and usu- ally belong to four ...

HmbC, a Protein of the HMG Family, Participates in the Regulation of Carotenoid Biosynthesis in Fusarium fujikuroi
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
In the fungus Fusarium fujikuroi, carotenoid production is up-regulated by light and down-regulated by the CarS RING finger protein, which modulates the mRNA levels of carotenoid pathway genes (car genes). To identify new ...

Controlled Transcription of Regulator Gene carS by Tet-on or by a Strong Promoter Confirms Its Role as a Repressor of Carotenoid Biosynthesis in Fusarium fujikuroi
(MDPI, 2020-12)
Carotenoid biosynthesis is a frequent trait in fungi. In the ascomycete Fusarium fujikuroi, the synthesis of the carboxylic xanthophyll neurosporaxanthin (NX) is stimulated by light. However, the mutants of the carS gene, ...

Identification and regulation of fusA, The polyketide synthase gene responsible for fusarin production in Fusarium fujikuroi
(American Society for Microbiology, 2012)
Fusarins are a class of mycotoxins of the polyketide family produced by different Fusarium species, including the gibberellin- producing fungus Fusarium fujikuroi. Based on sequence comparisons between polyketide synthase ...

Analysis of al-2 mutations in neurospora
(Public Library of Science, 2011)
The orange pigmentation of the fungus Neurospora crassa is due to the accumulation of the xanthophyll neurosporaxanthin and precursor carotenoids. Two key reactions in the synthesis of these pigments, the formation of ...
Artículo
A global perspective on carotenoids: metabolism, biotechnology, and benefits for nutrition and health.
(Elsevier, 2018-04-04)
Carotenoids are lipophilic isoprenoid compounds synthesized by all photosynthetic organisms and some non-photosynthetic bacteria and fungi. With some notable exceptions, animals (including humans) do not produce carotenoids ...

Comparative transcriptomic analysis unveils interactions between the regulatory CarS protein and light response in Fusarium
(BMC, 2019)
Background The orange pigmentation of the agar cultures of many Fusarium species is due to the production of carotenoids, terpenoid pigments whose synthesis is stimulated by light. The genes of the carotenoid pathway and ...

Biocontrol mechanisms of Thrichoderma strains
(Sociedad Española de MicrobiologÍa, 2004)
The genus Trichoderma comprises a great number of fungal strains that act as biological control agents, the antagonistic properties of which are based on the activation of multiple mechanisms. Trichoderma strains exert ...
