Glycosyltransferase efficiently controls phenylpropanoid pathway [PDF]

open access: yesBMC Biotechnology, 2008
Abstract Background In a previous study, anthocyanin levels in potato plants were increased by manipulating genes connected with the flavonoid biosynthesis pathway. However, starch content and tuber yield were dramatically reduced in the transgenic plants, which over-expressed dihydroflavonol reductase (DFR).

Auxin and tryptophan homeostasis are facilitated by the ISS1/VAS1 aromatic aminotransferase in arabidopsis [PDF]

open access: yes, 2015
Indole-3-acetic acid (IAA) plays a critical role in regulating numerous aspects of plant growth and development. While there is much genetic support for tryptophan-dependent (Trp-D) IAA synthesis pathways, there is little genetic evidence for tryptophan ...

Shikimate hydroxycinnamoyl transferase (HCT) activity assays in Populus nigra [PDF]

open access: yes, 2013
Lignin is a complex phenolic polymer deposited in secondarily-thickened plant cell walls. The polymer is mainly derived from the three primary monolignols: p-coumaryl, coniferyl and sinapyl alcohol which give rise to p-hydroxyphenyl, guaiacyl and ...
