Tomato phenylalanine ammonia-lyase gene family, highly redundant but strongly underutilized.
Phenylalanine ammonia-lyase (PAL) is an important enzyme in both plant development and pathogen defense. In all plants it is encoded by a multi-gene family, ranging in copy number from four in Arabidopsis to a dozen or more copies in some higher plants. Many studies indicate that alternate genes are differentially regulated in response to environmental stimuli. In this study, Southern blot and ...
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...
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 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 کاملCharacterisation of the willow phenylalanine ammonia-lyase (PAL) gene family reveals expression differences compared with poplar
Willow is an important biomass crop for the bioenergy industry, and therefore optimal growth with minimal effects of biotic and abiotic stress is essential. The phenylpropanoid pathway is responsible for the biosynthesis of not only lignin but also of flavonoids, condensed tannins, benzenoids and phenolic glycosides which all have a role in protecting the plant against biotic and abiotic stress...
