WHI-2 Regulates Intercellular Communication via a MAP Kinase Signaling Complex
(Frontiers Media, 2020)
he formation of the fungal mycelial network is facilitated by somatic cell fusion of germinating asexual spores (or germlings). Neurospora crassa germlings in close proximity display chemotropic growth that is dependent ...

Carotene-superproducing strains of Phycomyces
(1098-5336, 1978)
Production of fl-carotene by wild-type Phycomyces blakesleeanus can be stimulated by light, chemicals, regulatory mutations, and sexual interaction between mycelia of opposite sex. Through genetic manipulations, we have ...

Fungal cryptochrome with DNA repair activity reveals an early stage in cryptochrome evolution
(2015)
DASH (Drosophila, Arabidopsis, Synechocystis, Human)-type cryp- tochromes (cry-DASH) belong to a family of flavoproteins acting as repair enzymes for UV-B–induced DNA lesions (photolyases) or as UV-A/blue light photoreceptors ...

A glimpse into the basis of vision in the kingdom Mycota
(Elsevier, 2010)
Virtually all organisms exposed to light are capable of sensing this environmental signal. In recent years the photoreceptors that mediate the ability of fungi to " see" have been identified in diverse species, and ...

Role for Salmonella enterica enterobacterial common antigen in bile resistance and virulence
(American Society for Microbiology, 2003)
Passage through the digestive tract exposes Salmonella enterica to high concentrations of bile salts, powerful detergents that disrupt biological membranes. Mutations in the wecD or wecA gene, both of which are involved ...

Adaptive response of saccharomyces hosts to totiviridae L-A dsRNA viruses Is achieved through intrinsically balanced action of targeted transcription factors
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Totiviridae L-A virus is a widespread yeast dsRNA virus. The persistence of the L-A virus alone appears to be symptomless, but the concomitant presence of a satellite M virus provides a killer trait for the host cell. The ...

Genome Instability and Transcription Elongation Impairment in Human Cells Depleted of THO/TREX
(Public Library of Science, 2011)
THO/TREX connects transcription with genome integrity in yeast, but a role of mammalian THO in these processes is uncertain, which suggests a differential implication of mRNP biogenesis factors in genome integrity in yeast ...

Three Genes Involved in Different Signaling Pathways, carS, wcoA, and acyA, Participate in the Regulation of Fusarin Biosynthesis in Fusarium fujikuroi
(MDPI, 2024)
The phytopathogenic fungus Fusarium fujikuroi has a rich secondary metabolism which includes the synthesis of very different metabolites in response to diverse environmental cues, such as light or nitrogen. Here, we focused ...

Rat1 promotes premature transcription termination at R-loops
(Oxford University Press, 2024-04-24)
Certain DNA sequences can adopt a non-B form in the genome that interfere with DNA-templated processes, including transcription. Among the sequences that are intrinsically difficult to transcribe are those that tend to ...
