Phenylpropanoid pathway intermediates regulate transient expression of a chalcone synthase gene promoter.
A chimeric gene construct containing a bean chalcone synthase (CHS) promoter fused to the chloramphenicol acetyltransferase (CAT) reporter gene was strongly expressed when electroporated into alfalfa protoplasts that were then exposed to a fungal elicitor. Low concentrations (5 x 10(-6) to 10(-4) M) of exogenously applied trans-cinnamic acid (CA), the first intermediate of the phenylpropanoid p...
متن کاملUV-B, UV-A, and blue light signal transduction pathways interact synergistically to regulate chalcone synthase gene expression in Arabidopsis.
UV and blue light stimulate transcription of key flavonoid biosynthesis genes in a range of higher plants. Here, we provide evidence that several distinct "inductive" and "synergistic" UV/blue phototransduction pathways regulate chalcone synthase (CHS) gene transcription and transcript accumulation in Arabidopsis leaf tissue. Experiments with the long-hypocotyl hy4-2.23N mutant showed that sepa...

UV and blue light stimulate transcription of key flavonoid biosynthesis genes in a range of higher plants. Here, we provide evidence that several distinct "inductive" and ''synergistic" UV/blue phototransduction pathways regulate chalcone synthase (CHS) gene transcription and transcript accumulation in Arabidopsis leaf tissue. Experiments with the long-hypocotyl hy4-2.23N mutant showed that sep...
متن کاملPromoter elements in the aflatoxin pathway polyketide synthase gene.
PksA catalyzes the formation of the polyketide backbone necessary for aflatoxin biosynthesis. Based on reporter assays and sequence comparisons of the nor1-pksA intergenic region in different aflatoxin-producing Aspergillus species, cis-acting elements for the aflatoxin pathway-specific regulatory protein, AflR, and the global-acting regulatory proteins BrlA and PacC are involved in pksA promot...
متن کاملPromoter-Associated RNAs Regulate HSPC152 Gene Expression in Malignant Melanoma
The threshold of 200 nucleotides (nt) conventionally divides non-coding RNAs (ncRNA) into long ncRNA (lincRNA, that have more than 200 nt in length) and the remaining ones which are grouped as “small” RNAs (microRNAs, small nucleolar RNAs and piwiRNAs). Promoter-associated RNAs (paRNAs) are generally 200–500 nt long and are transcribed from sequences positioned in the promoter regions of genes....
