Analysis of flavanone 3-hydroxylase in Arabidopsis seedlings. Coordinate regulation with chalcone synthase and chalcone isomerase.
A genomic clone encoding flavanone 3-hydroxylase (F3H) was isolated from Arabidopsis thaliana. The deduced amino acid sequence is 72 to 94% identical to all previously reported F3H proteins. Low-stringency DNA blot analysis indicated that F3H is encoded by a single gene in Arabidopsis. The F3H locus was mapped to the bottom of chromosome 3 and therefore does not correspond to any of the 13 flav...

متن کاملChalcone 3- Hydroxylase: yellow colouration of flowers
Background Different yellow pigments can be responsible for the yellow colouration of flowers. This includes the wide-spread carotenoids, but also betalains, quinones, yellow flavonoids and anthochlore pigments (chalcones and aurones). Many popular ornamental plants do not produce yellow varieties or only ivory and pale yellow varieties despite of intensive conventional breeding efforts. World-...
متن کاملNucleotide variation at the CHALCONE ISOMERASE locus in Arabidopsis thaliana.
An approximately 1.9-kb region encompassing the CHI gene, which encodes chalcone isomerase, was sequenced in 24 worldwide ecotypes of Arabidopsis thaliana (L.) Heynh. and in 1 ecotype of A. lyrata ssp. petraea. There was no evidence for dimorphism at the CHI region. A minimum of three recombination events was inferred in the history of the sampled ecotypes of the highly selfing A. thaliana. The...
متن کاملThe Arabidopsis transcription factor MYB12 is a flavonol-specific regulator of phenylpropanoid biosynthesis.
Comprehensive functional data on plant R2R3-MYB transcription factors is still scarce compared to the manifold of their occurrence. Here, we identified the Arabidopsis (Arabidopsis thaliana) R2R3-MYB transcription factor MYB12 as a flavonol-specific activator of flavonoid biosynthesis. Transient expression in Arabidopsis protoplasts revealed a high degree of functional similarity between MYB12 ...
