Journal ArticleDOI
Allelopathy and Exotic Plant Invasion: From Molecules and Genes to Species Interactions
TL;DR: Evidence that Centaurea maculosa (spotted knapweed), an invasive species in the western United States, displaces native plant species by exuding the phytotoxin (–)-catechin from its roots is presented and support a “novel weapons hypothesis” for invasive success.
Journal ArticleDOI
Molecular and Biochemical Characterization of an Enzyme Responsible for the Formation of Hypericin in St. John's Wort (Hypericum perforatum L.)
TL;DR: A direct and complex conversion of emodin to HyH that is solely catalyzed by Hyp-1, a Bet.v.1 class allergen from H. perforatum is demonstrated.
Journal ArticleDOI
Isolation and characterization of an RIP (ribosome-inactivating protein)-like protein from tobacco with dual enzymatic activity.

TL;DR: Tobacco RIP (TRIP) was isolated from tobacco leaves and purified using ion exchange and gel filtration chromatography in combination with yeast ribosome depurination assays and may be considered a dual activity enzyme showing RIP-like activity and Fe-SOD characteristics.
Journal ArticleDOI
Ribosome-inactivating proteins in plant biology.
Sang-Wook Park,Sang-Wook Park,Ramarao Vepachedu,Ramarao Vepachedu,Neelam Sharma,Jorge M. Vivanco +5 more
TL;DR: Ribosome-inactivating proteins are a group of cytotoxic Af-glycosidases that specifically cleave nucleo tide N-C glycosidic bonds.
Journal ArticleDOI
Root specific elicitation and exudation of fluorescent β-carbolines in transformed root cultures of Oxalis tuberosa
TL;DR: Transformed root cultures of oca make a simple, reliable and well-defined model system to investigate the molecular and metabolic exudation of fluorescent β-carboline biosynthesis, and to evaluate the biological significance of the phenomenon of root exudations of fluorescent metabolites.
