Defense heterosis as a novel plant protection strategy: From theory to breeding practice
New Plant Protection, EarlyView.Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

Naringin a potent antioxidant used as bioavailibility enhancer for terbinafine hydrochloride
Journal of Applied Pharmaceutical Research, 2014 The poor bioavailability of drugs has been identified as the single most important challenge in oral drug delivery. Prominent among the factors responsible for this are the oxidative metabolic activity of the intestinal and hepatic cytochrome P450 enzyme

Structure Elucidation of Biflavones With Ether Bonds by NMR-Spectroscopy-Structure Revisions of Loniflavone and Methylloniflavone. [PDF]
Magn Reson ChemThe structures of the biflavones loniflavone and methylloniflavone from Lonicera japonica have to be revised to ochnaflavone and methylloniflavone based on two NMR approaches without derivatization. ABSTRACT For the structure elucidation of biflavones in which the subunits are linked by an ether bridge, two NMR spectroscopic approaches are shown to ...

Identification of a Bifunctional Maize C- and O-Glucosyltransferase [PDF]
, 2013 Flavonoids accumulate in plant vacuoles usually as O-glycosylated derivatives, but several species can also synthesize flavonoid C-glycosides. Recently, we demonstrated that a flavanone 2-hydroxylase (ZmF2H1, CYP93G5) converts flavanones to the ...
