Isolation and expression analysis of two DOPA dioxygenases in Phytolacca americana.
Betacyanins and anthocyanins, two main red flower pigments, never occur together in the same plant. Although the anthocyanin biosynthetic pathway has been well analyzed, the biosynthetic genes and the regulatory mechanism of the betacyanin biosynthesis are still obscure. We cloned two cDNAs of DOPA dioxygenase from Phytolacca americana, PaDOD1 and PaDOD2, that may be involved in the betalain bi...

Purification of the n-BuOH fraction of the aqueous alcoholic extract from the roots of Phytolacca americana resulted in the isolation of two triterpene saponins named esculentoside B (1), and esculentoside A (2). The structures of isolated compounds were characterized on the basis of extensive spectral data (1D and 2D NMR; and MS) and in comparison with their Nuclear Magnetic Resonance (NMR) an...
متن کاملCloning and characterization of polyphenol oxidase cDNAs of Phytolacca americana.
Two cDNA clones encoding polyphenol oxidases were isolated from a cDNA library constructed from a log-phase suspension culture of Phytolacca americana (pokeweed) producing betalains. The clones exhibit 93 and 86% sequence identity at the nucleotide and deduced amino acid levels, respectively. Both clones contain two copper-binding domains characterized by histidine-rich regions, which are found...
