cis-element combinations determine phenylalanine ammonia-lyase gene tissue-specific expression patterns.
The bean phenylalanine ammonia-lyase gene 2 (PAL2) is expressed in the early stages of vascular development at the inception of xylem differentiation, associated with the synthesis of lignin precursors. This is part of a complex program of developmental expression regulating the synthesis of functionally diverse phenylpropanoid natural products. Analysis of the expression of PAL2 promoter-beta-...
متن کاملYeast Phenylalanine Ammonia-lyase
I?henyialanine ammonia-lyase from the yeast Rhodotorula gluiinis was purified by salt fractionations and Sephadex chromatography. Density gradient centrifugation and Sephadex chromatography indicated its molecular weight to be about 275,000. Enzymatic deamination of several ring-substituted phenylalanine analogues and n-phenylalanine was studied. While cinnamic acid, a product of deamination, a...
متن کاملCombinations of closely situated cis-acting elements determine tissue-specific patterns and anterior extent of early Hoxc8 expression.
We have used a transgene mutation approach to study how expression domains of Hoxc8 are established during mouse embryogenesis. A cis-regulatory region located 3 kb upstream from the Hoxc8 translational start site directs the early phase of expression. Four elements, termed A, B, C, and D, were previously shown to direct expression to the neural tube. Here we report that a fifth element, E, loc...
متن کاملGenomic Characterization of Phenylalanine Ammonia Lyase Gene in Buckwheat
Phenylalanine Ammonia Lyase (PAL) gene which plays a key role in bio-synthesis of medicinally important compounds, Rutin/quercetin was sequence characterized for its efficient genomics application. These compounds possessing anti-diabetic and anti-cancer properties and are predominantly produced by Fagopyrum spp. In the present study, PAL gene was sequenced from three Fagopyrum spp. (F. tataric...
متن کاملTruncated phenylalanine ammonia-lyase expression in tomato (Lycopersicon esculentum).
Southern blot analyses of genomic DNA fragments suggest there are five different classes of phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) genomic sequence in tomato (Lycopersicon esculentum). Isolation and subsequent sequence analysis of three examples from genomic libraries reveal highly homologous coding sequences but also a surprisingly high frequency of single point mutations which would tr...
