Conceptualization and Realization of a Vibrating Intrinsic Reverberation Chamber for Plant Exposure to Radio Frequency Electromagnetic Fields

Bioelectromagnetics, Volume 46, Issue 8, December 2025.
ABSTRACT The increasing use of mobile communication devices and wireless data transfer leads to public concerns about potential negative impacts on the living world, resulting from the emitted radio frequency‐electromagnetic fields (RF‐EMF). In order to provide knowledge‐based information on how RF‐EMF might affect biological organisms, well‐controlled

Tissue Culture and Agrobacterium-Mediated Transformation on Rosa Hybrida L. 'Christian Dior' [PDF]

, 1997
Callus induction from leaf explants of Rosa hybrida L. 'Christian Dior' was established. Two types of auxins (2.4-D and NAA) at three concentrations (4.5, 9.0 and 13.5 µM) and two types of cytokinins (kinetin and BA) at three concentrations (2.3, 4.7 ...

Silicon-induced changes in antifungal phenolic acids, flavonoids, and key phenylpropanoid pathway genes during the interaction between miniature roses and the biotrophic pathogen Podosphaera pannosa [PDF]

, 2011
Application of 3.6 mm silicon (Si+) to the rose (Rosa hybrida) cultivar Smart increased the concentration of antimicrobial phenolic acids and flavonoids in response to infection by rose powdery mildew (Podosphaera pannosa). Simultaneously, the expression

Ultraviolet B Irradiation of Diplocarpon rosae for the Control of Black Spot Disease in Roses

Journal of Phytopathology, Volume 173, Issue 6, November/December 2025.
ABSTRACT Ultraviolet‐B (UV‐B) irradiation was evaluated as a non‐chemical strategy for suppressing black spot disease in roses (Rosa × hybrida) caused by Diplocarpon rosae. Daily 1‐h night‐time UV‐B irradiation significantly reduced fungal colony growth on potato dextrose agar, resulting in colony diameters that were 20.4%–37.7% of the non‐UV control ...

Genetic Regulation of Anthocyanin Biosynthesis in Cornus Species: The Roles of R2R3‐MYB Transcription Factors

Plant Direct, Volume 9, Issue 10, October 2025.
ABSTRACT Flowering dogwood (Cornus florida L.) and Asian dogwood (Cornus kousa F. Buerger ex Hance) are popular deciduous ornamental trees native to a wide range of the eastern and southeastern United States and East Asia, respectively. Anthocyanin pigments enhance desirable pink or dark red colored bracts in dogwoods. Although anthocyanin biosynthesis

Disequilibrium of flavonol synthase and dihydroflavonol-4-reductase expression associated tightly to white versus red color flower formation in plants

Frontiers in Plant Science, 2016
Flower colour is the main character throughout the plant kingdom. Though substantial information exists regarding the structural and regulatory genes involved in anthocyanin and flavonol biosynthesis, little is known that what make a diverse white versus
