Arabidopsis APx-R Is a Plastidial Ascorbate-Independent Peroxidase Regulated by Photomorphogenesis
Antioxidants, 2021 Peroxidases are enzymes that catalyze the reduction of hydrogen peroxide, thus minimizing cell injury and modulating signaling pathways as response to this reactive oxygen species.

Molecular interactions of BBX24 and BBX25 with HYH, HY5 HOMOLOG, to modulate Arabidopsis seedling development [PDF]
, 2013 BBX24 and BBX25 are two important transcriptional regulators, which regulate seedling photomorphogenesis in Arabidopsis. Very recently, we have shown that BBX24 and BBX25 negatively regulate the expression of BBX22, reducing the function of HY5, by ...

The Plant Genome, Volume 19, Issue 2, June 2026.Abstract Rice (Oryza sativa L.) tillering is a critical determinant of grain yield, yet the genetic mechanisms underlying non‐productive tillers remain poorly understood. Here, we report a novel high‐tillering (HT) phenotype derived from a cross between the elite cultivar Milyang23 and weedy rice Hapcheonaengmi3. The HT phenotype was absent in parental

Hormonal networks involved in apical hook development in darkness and their response to light [PDF]
, 2014 In darkness, the dicot seedlings produce an apical hook as result of differential cell division and extension at opposite sides of the hypocotyl. This hook protects the apical meristem from mechanical damage during seedling emergence from the soil.

Photophysics of Biological and Biomimetic Sunscreen Molecules
ChemPhotoChem, Volume 10, Issue 5, May 2026.Recent photochemical and photophysical research into natural and nature‐inspired UV filter molecules is reviewed, with a focus on the application of these systems in next‐generation sunscreens. The results of time‐resolved UV spectroscopy experiments and theoretical studies are discussed.

Plant Communications, 2020 Green plants on the earth have evolved intricate mechanisms to acclimatize to and utilize sunlight. In Arabidopsis, light signals are perceived by photoreceptors and transmitted through divergent but overlapping signaling networks to modulate plant ...

Enhancing the vase life of cut roses through spectral optimisation during greenhouse cultivation
Annals of Applied Biology, Volume 188, Issue 3, Page 656-673, May 2026.Here, we examined three red‐to‐blue (R:B) light emitting diode (LED) ratios (90:10, 80:20 and 70:30) in two cut rose cultivars. All treatments enhanced photosynthesis, with 90:10 showing the strongest effects—raising chlorophyll, carotenoids, anthocyanins and carbohydrate levels, and extending vase life by up to 30%.

Gayana: Botanica, 2023 In recent decades the fluence of ultraviolet-B (UV-B) radiation striking the ground has increased as a consequence of ozone depletion at southern latitudes. This phenomenon has sparked much interest in unravelling how plants acclimate to this condition.

Genetic Basis of UV Bullseye Size Variations in Turnip Rape (Brassica rapa subsp. oleifera)
Plant Biotechnology Journal, Volume 24, Issue 5, Page 3189-3200, May 2026.ABSTRACT Floral ultraviolet (UV) patterns are visible to bee pollinators and can affect crop yields by impacting pollinator visitation. However, the mechanisms underlying the intraspecific variations of UV bullseye size remain largely unknown. We analyse the ecological consequences and genetic basis of floral UV bullseye size variation in an important ...

Effect of Extended Photoperiod with a Fixed Mixture of Light Wavelengths on Tomato Seedlings
HortScience, 2020 Light is an abiotic factor, and its quality, quantity, and photoperiod can be modulated to work as eustress inductors to regulate plant processes.
