In seed plants, strigolactones (SLs) regulate architecture and induce mycorrhizal symbiosis in response to environmental cues. SLs are formed by combined activity of the carotenoid cleavage dioxygenases (CCDs) 7 8 from 9-cis-β-carotene, leading carlactone that is converted cytochromes P450 (clade 711; MAX1 Arabidopsis) into various SLs. As Physcomitrella patens possesses CCD7 CCD8 homologs but lacks MAX1, we investigated if PpCCD7 together with PpCCD8 form how deletion these enzymes...
Rhodopsins are membrane-embedded photoreceptors found in all major taxonomic kingdoms using retinal as their chromophore. They play well-known functions different biological systems, but roles fungi remain unknown. The filamentous fungus Fusarium fujikuroi contains two putative rhodopsins, CarO and OpsA. gene carO is light-regulated the predicted polypeptide conserved residues required for proton pumping. We aimed to elucidate expression cellular location of fungal rhodopsin CarO, its...
Fungal secondary metabolites (SMs) comprise a vast collection of compounds expendable for these organisms under laboratory conditions. They exhibit enormous chemical diversity, and usually belong to four major families: terpenoids, polyketides, non-ribosomal peptides, or combination the last two. Their functions are very diverse normally associated with greater fitness producing fungi in their environment, which often compete other microorganisms interact host plants. Many SMs have...
Previous complementation and mapping of mutations that change the usual yellow color Zygomycete Phycomyces blakesleeanus to white or red led definition two structural genes for carotene biosynthesis. We have cloned one these genes, carRA , by taking advantage its close linkage other, carB responsible phytoene dehydrogenase. The sequences wild type six mutants been established, compared with in other organisms, correlated mutant phenotypes. coding are separated 1,381 untranslated nucleotides...
The car gene cluster of the ascomycete Fusarium fujikuroi encodes two enzymes responsible for torulene biosynthesis (CarRA and CarB), an opsin-like protein (CarO), a putative carotenoid cleaving enzyme (CarX). It was presumed that CarX catalyzes formation major in F. fujikuroi, neurosporaxanthin, cleavage product torulene. However, targeted deletion carX did not impede neurosporaxanthin biosynthesis. On contrary, DeltacarX mutants showed significant increase total content, indicating...
N-methyl-N'-nitro-N-nitrosoguanidine (nitrosoguanidine) and to a lesser extent UV radiation are very mutagenic for Gibberella microconidia. The recommended nitrosoguanidine doses lead much higher frequencies of mutants than found in other microorganisms. frequency among the survivors increases linearly with dose (molar concentration X time); absolute number viable given population reaches maximum ca. 0.7 M s. microconidia uninucleate. onset germination brings about increased lethality...
ABSTRACT DASH ( Drosophila , Arabidopsis Synechocystis human) cryptochromes (cry-DASHs) constitute a subgroup of the photolyase cryptochrome family with diverse light-sensing roles, found in most taxonomical groups. The genome Fusarium fujikuroi phytopathogenic fungus rich secondary metabolism, contains gene encoding putative cry-DASH, named CryD. expression cryD is induced by light wild type, but not mutants “white collar” wcoA . Targeted Δ show light-dependent phenotypic alterations,...
We performed a systematic study of the bactericide and bacterial anti-adhesive properties nanocrystalline diamond (NCD) microcrystalline (MCD) in comparison to other important industrial materials, such as copper, silver, polyethylene (Poly), stainless steel (SS). The data show that NCD has better activity than Ag, but not good Cu. MCD, on hand, does appear have significant anti-bacterial activity. superlative NCD, mechanical hardness, resistance oxidation corrosion, biological compatibility...
