Logi sisse

A gene from groundnut (Arachis hypogaea) coding for stilbene synthase was transferred together with a chimaeric kanamycin resistance gene. It was found to be rapidly expressed after induction with UV light and elicitor in tobacco cells (Nicotiana tabacum). Comparative studies of stilbene synthase

Production of highly bioactive resveratrol analogues pterostilbene and piceatannol in metabolically engineered grapevine cell cultures.

Logi sisse

Grapevine stilbenes, particularly trans-resveratrol, have a demonstrated pharmacological activity. Other natural stilbenes derived from resveratrol such as pterostilbene or piceatannol, display higher oral bioavailability and bioactivity than the parent compound, but are far less abundant in natural

Enhanced production of resveratrol derivatives in tobacco plants by improving the metabolic flux of intermediates in the phenylpropanoid pathway.

Logi sisse

The biosynthesis of flavonoids such as anthocyanin and stilbenes has attracted increasing attention because of their potential health benefits. Anthocyanins and stilbenes share common phenylpropanoid precursor pathways. We previously reported that the overexpression of sweetpotato IbMYB1a induced

A stress-inducible resveratrol O-methyltransferase involved in the biosynthesis of pterostilbene in grapevine.

Stilbenes are considered the most important phytoalexin group in grapevine (Vitis vinifera) and they are known to contribute to the protection against various pathogens. The main stilbenes in grapevine are resveratrol and its derivatives and, among these, pterostilbene has recently attracted much

Logi sisse

The expression and functionality of a resveratrol synthase (RS) gene from peanut (Arachis hypogaea) was studied using an Agrobacterium tumefaciens-mediated transient expression system in Nicotiana benthamiana leaves. Functional analysis of RS was demonstrated by tracking its expression during 96 h.

Co-expression of VpROMT gene from Chinese wild Vitis pseudoreticulata with VpSTS in tobacco plants and its effects on the accumulation of pterostilbene.

Plant secondary metabolites, such as stilbenes, have fungicidal potential and have been found in several plant species. Stilbenes in grapevine, such as resveratrol and pterostilbene, have recently attracted much attention, they are not only helping the plant to fight against pathogen attack, but

A specific allele of MYB14 in grapevine correlates with high stilbene inducibility triggered by Al3+ and UV-C radiation.

UNASSIGNED The structural differences of MYB14 promoter in two grapevine genotypes affect the expression of MYB14 and stilbene synthesis in response to Al3+ and UV-C radiation. Grapevines provide an important fruit crop worldwide, but production is often limited by pathogen infection. Stilbenes, a

Stilbenoid prenyltransferases define key steps in the diversification of peanut phytoalexins.

Defense responses of peanut (Arachis hypogaea) to biotic and abiotic stresses include the synthesis of prenylated stilbenoids. Members of this compound class show several protective activities in human disease studies, and the list of potential therapeutic targets continues to expand. Despite their

A plant cell-based system that predicts aβ42 misfolding: potential as a drug discovery tool for Alzheimer's disease.

Logi sisse

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the accumulation of amyloid β (Aβ) peptides and the failure of mechanisms to clear toxic aggregates. The Aβ42 peptide is considered to be a causative factor that underlies the pathophysiology of AD, in part due to

The transcription factor MYB15 is essential for basal immunity (PTI) in Chinese wild grape.

Logi sisse

MYB15 promoter of Vitis quinquangularis has potential as a target for disease resistance breeding, and its involvement in PTI is associated with a range of defense mechanisms. China is a center of origin for Vitis and is home to diverse wild Vitis genotypes, some of which show superior pathogen
