additional information
-
expression in Arabidopsis thaliana transparent testa 5 mutant which is defective in naringenin production and therefore gives yellow seeds results in recovery of normal seed coat colour
additional information
-
production of enzyme derivatives in which the Cys residue has been converted to a series of unnatural amino acids. The results demonstrate that the Cys residue does not function as an acid-base or nucleophilic group during catalysis nor does it play any role in the substrate inhibition
additional information
SbCHI-overexpressing and SbCH-silenced transgenic hairy root lines are established by using an Agrobacterium rhizogenes-mediated system. SbCHI-overexpressing hairy root lines show enhanced SbCHI gene expression and produce more flavones, i.e. baicalin, baicalein, and wogonin, than the control hairy root line, phenotype, overview
