Variability of Chalcone Synthase in Chamomile Accessions (Matricaria chamomilla)
Planta MedicaAbstractChamomile (Matricaria chamomilla) is an important medicinal plant whose beneficial activities partly rely on certain flavonoids. The first dedicated step in flavonoid biosynthesis is chalcone synthase (CHS, EC 2.3.1.74). The genomic DNA of CHS was studied in six chamomile specimens from different genotypes to describe interspecimen, as well as ...

An allelic series for the chalcone synthase locus in Arabidopsis
Gene, 2000Five new alleles of the Arabidopsis chalcone synthase (CHS) locus, tt4, have been characterized at the gene, protein, and end product levels as a genetic approach to understanding structure-function relationships in a key enzyme of plant secondary metabolism.

Divergent evolution of the thiolase superfamily and chalcone synthase family
Molecular Phylogenetics and Evolution, 2008Enzymes of the thiolase superfamily catalyze the formation of carbon-carbon bond via the Claisen condensation reaction. Thiolases catalyze the reversible non-decarboxylative condensation of acetoacetyl-CoA from two molecules of acetyl-CoA, and possess a conserved Cys-His catalytic diad.

Organization of the genes encoding chalcone synthase in Pisum sativum
Plant Molecular Biology, 1993To analyze the regulation of defense-related genes by signal molecules produced by phytopathogens, we isolated genes that encode chalcone synthase (CHS) in Pisum sativum. We have obtained seven independent genomic clones that contain at least seven classes of CHS genes, identified by the hybridization analysis to CHS cDNA and by the restriction mapping

Chalcone synthase( CHS) and chalcone isomerase( CHI) are key enzymes in the biosynthesis pathway of flavonoids. In this study,unigenes for CHS and CHI were screened from the transcriptome database of Arisaema heterophyllum. The open reading frame( ORFs) of chalcone synthase( Ah CHS) and chalcone isomerase( Ah CHI) were cloned from the plant by RT-PCR ...

Transcriptional Control of Chalcone Synthase by Environmental Stimuli
Journal of Plant Research, 2000UV protectants and antimicrobial compounds phytoalexins. Chalcone synthase (CHS), the key enzyme of flavonoid biosynthesis, is induced by environmental stresses such as UV, mechanical wounding and pathogen attack. Characterization of the cis elements and trans factors involved in CHS expression has enabled delineation of the terminal stage of the ...
