MOLECULAR ANALYSIS OF THE SULFUR REGULATORY CIRCUIT OF NEUROSPORA CRASSA
The sulfur regulatory circuit of the filamentous fungus, Neurospora crassa, consists of a set of unlinked structural genes which encode sulfur catabolic and two major regulatory genes which govern their expression. The cys-3 regulatory gene encode a transacting regulatory protein which activates the expression of cys-14 and ars, whereas the other regulatory genes Scon-l and Scon-2 appear to...
متن کاملPromotion of specific in vitro transcription by excised "TATA" box sequences inserted in a foreign nucleotide environment.
We have cloned into plasmid pBR322 a DNA fragment extending from position -32 to position -12 of the adenovirus type 2 major late promoter region (position +1 referring to the cap site). In vitro transcription experiments show that this 21 base pair sequence, which contains the Goldberg-Hogness or "TATA" box, is both necessary and sufficient for specific initiation of transcription by RNA polym...
متن کاملExploring the bZIP transcription factor regulatory network in Neurospora crassa
Transcription factors (TFs) are key nodes of regulatory networks in eukaryotic organisms, including filamentous fungi such as Neurospora crassa. The 178 predicted DNA-binding TFs in N. crassa are distributed primarily among six gene families, which represent an ancient expansion in filamentous ascomycete genomes; 98 TF genes show detectable expression levels during vegetative growth of N. crass...
متن کاملThinking outside the TATA box.
When I was doing my PhD research, in the middle of the last century, the nature and complexity of the RNA transcripts of the genome was a topic of lively debate, into which my own work became drawn. The complexity of the mRNA population in a given tissue, celltype or developmental stage—considered as transcripts that were polyadenylated and associated with ribosomes—was estimated to represent s...
