Biotrophy may also depend on additional controls, such as catabolite
repression of CWDE synthesis resulting from the characteristic influx of photosynthates to infected areas (Cooper, 1983).
To determine why the reb D gene was not being expressed, sequence analysis upstream of the open reading frame was perforrned, and a potential catabolite
repressor sequence was identified.
9 process is based on the fact that the main compounds cited in literature as being responsible for the corked taste in wine are metabolite and catabolite
results of certain varieties of mold.
As Schizochytrium is a slow growing heterotroph consuming glucose at a slow rate, wai cultivation in a non carbon catabolite
repression condition or in an increased acetyl-CoA synthethase state gives rise to higher growth and glucose consumption rates (27).
Enzyme production regulation is influenced by catabolite
Enrichment techniques for the selection of catabolite
repression-resistant mutants of Trichoderma as producer of cellulase.
The decreased activity in the later phase of growth was probably due to catabolite
repression by glucose released from starch hydrolysis.
We do not imply that catabolite
regulation is the sole basis for this effect, but rather that catabolite
regulation may be indirect, since the major evolutionary benefit derived from catabolite
repressive mechanism may have resulted in enhancing the endophyte's ability to efficiently scavenge nutrients from such a nutrient poor location, thereby avoiding the usual cellular invasive, destructive mode for obtaining nutrient used by most biotrophic pathogenic fungi.
DOPAC is a catabolite
of dopamine that occurs naturally in squid ink.
The endo-acting [beta]-glucanase secretion is controlled by glucose-mediated catabolite
repression and induced mainly by media containing cell-wall materials.
IDO upregulates regulatory T cells via tryptophan catabolite
and suppresses encephalitogenic T cell responses in experimental autoimmune encephalomyelitis.
Relaxation of catabolite
repression in streptomycin-dependent Escherichia coli.
