Isolation and promoter analysis of a chalcone synthase gene PtrCHS4 from Populus trichocarpa.
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
As perennial plants, Populus species are constantly exposed to environmental stresses, such as wounding and pathogen attack, which lead to production of compounds including lignin, flavonoids and phytoalexins. Chalcone synthase (CHS) is a key enzyme in the flavonoid biosynthesis pathway. In this
A CACGTG motif of the Antirrhinum majus chalcone synthase promoter is recognized by an evolutionarily conserved nuclear protein.

Logi sisse
In the chalcone synthase gene of Antirrhinum majus (snapdragon), 150 base pairs of the 5' flanking region contain cis-acting signals for UV light-induced expression. A nuclear factor, designated CG-1, specifically recognizes a hexameric motif with internal dyad symmetry, CACGTG, located within this
Expression of an anther-specific chalcone synthase-like gene is correlated with uninucleate microspore development in Nicotiana sylvestris.

Two cDNA clones, specifically expressed in Nicotiana sylvestris anthers during uninucleate microspore development, were isolated using a subtractive hybridization approach. Sequence analysis showed that one of them, NSCHSLK, displayed a high level of similarity to several anther-specific chalcone
Sequence analysis of a "true" chalcone synthase (chs_H1) oligofamily from hop (Humulus lupulus L.) and PAP1 activation of chs_H1 in heterologous systems.

Screening of a cDNA library of the hop cv. Osvald's 72 and genomic cloning were used to isolate members of an oligofamily of chs_H1 genes that codetermine the biosynthesis of prenylated chalcones known to be valuable medicinal compounds present in hop (Humulus lupulus L.). chs_H1 oligofamily members
Functional dissection of a bean chalcone synthase gene promoter in transgenic tobacco plants reveals sequence motifs essential for floral expression.

Expression of chalcone synthase (CHS), the first enzyme in the flavonoid branch of the phenylpropanoid biosynthetic pathway in plants, is induced by developmental cues and environmental stimuli. We used plant transformation technology to delineate the functional structure of the French bean CHS15
A Nuclear Factor Recognizing a Positive Regulatory Upstream Element of the Antirrhinum majus Chalcone Synthase Promoter.

Logi sisse
A positive regulatory element directing maximal expression of the Antirrhinum majus chalcone synthase promoter was characterized by protein-DNA-interaction studies and cis deletion analysis. The positive regulatory element consists of a 47 base pair direct repeat between positions -564 and -670 and
Purification of tobacco nuclear proteins binding to a CACGTG motif of the chalcone synthase promoter by DNA affinity chromatography.

The activity of various light-regulated and developmentally regulated plant gene promoters critically depends upon the presence of a conserved sequence with a central CACGTG motif. Using band-shift assays, we have identified nuclear factor(s) from Nicotiana tabacum, termed CG-1, that specifically
Molecular characterization and functional analysis of chalcone synthase from Syringa oblata Lindl. in the flavonoid biosynthetic pathway.
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
The flower color of Syringa oblata Lindl., which is often modulated by the flavonoid content, varies and is an important ornamental feature. Chalcone synthase (CHS) catalyzes the first key step in the flavonoid biosynthetic pathway. However, little is known about the role of S. oblata CHS (SoCHS) in
Evolution of a novel and adaptive floral scent in wild tobacco.
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
Many plants emit diverse floral scents that mediate plant-environment interactions and attain reproductive success. However, how plants evolve biosynthesis of novel and adaptive floral volatiles remains unclear. Here, we show that in the wild tobacco, Nicotiana attenuata, a dominant species-specific
Biosynthesis of the Dihydrochalcone Sweetener Trilobatin Requires Phloretin Glycosyltransferase 2

Epidemics of obesity and type 2 diabetes drive strong consumer interest in plant-based low calorie sweeteners. Trilobatin (phloretin-4'-O-glucoside) is a sweetener found at high concentrations in the leaves of a range of crabapple (Malus) species, but not in domesticated apple (M. × domestica)

BACKGROUND
Cytosine methylation is involved in epigenetic control of gene expression in a wide range of organisms. An increasing number of examples indicate that changing the frequency of cytosine methylation in the genome is a feasible tool to engineer novel traits in plants. Although demethylating

Epimedium species have been widely used both as traditional Chinese medicinal plants and ornamental perennials. Both flavonols, acting as the major bioactive components (BCs) and anthocyanins, predominantly contributing to the color diversity of Epimedium flowers belong to different classes of
The tobacco bZIP transcription factor BZI-1 binds to G-box elements in the promoters of phenylpropanoid pathway genes in vitro, but it is not involved in their regulation in vivo.
