Phytochrome A Regulates Carbon Flux in Dark Grown Tomato Seedlings

Frontiers in Plant Science, 2019
Phytochromes comprise a small family of photoreceptors with which plants gather environmental information that they use to make developmental decisions, from germination to photomorphogenesis to fruit development.

Differential response of Palmer amaranth (Amaranthus palmeri) seed germination and seedling emergence under variable environmental conditions

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Palmer amaranth (Amaranthus palmeri S. Watson) is a eudicot weed that is considered as one of the most problematic weed species. It is reported to overcome several environmental and management stresses under field conditions. Research was conducted in a growth chamber and greenhouse to evaluate the effects of different stress parameters such ...

The Phytochrome B/Phytochrome C Heterodimer Is Necessary for Phytochrome C-Mediated Responses in Rice Seedlings

PLoS ONE, 2014
PhyC levels have been observed to be markedly lower in phyB mutants than in Arabidopsis or rice wild type etiolated seedlings, but the mechanism of this phenomenon has not been fully elucidated.In the present study, we investigated the mechanism by which phyB affects the protein concentration and photo-sensing abilities of phyC and demonstrated that ...

Blue light modulates the interactive effects of far-red light and day–night temperature difference on the growth, morphology and physiology of arugula and lettuce

Frontiers in Plant Science
IntroductionFar-red (FR; 700–800 nm) light and the difference between day and night temperature (DIF) interactively regulate plant morphology and growth. FR light and +DIF synergistically promote stem elongation, often reducing leaf expansion and overall

Under the Cover of Darkness: A Transcriptomic Exploration of Clubroot During the Night

Plant Direct, Volume 10, Issue 6, June 2026.
ABSTRACT Plasmodiophora brassicae (Phytomyxea, Rhizaria) is the etiological agent of clubroot disease, one of the most important diseases of Brassicaceae crops. Alteration of metabolism and hormone homeostasis leads to the formation of tumor‐like galls in the roots of affected plants.

Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, Volume 4, Issue 2, June 2026.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high‐throughput RNA sequencing

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Shade Avoidance Restricts Soybean Breeding Progress and Increases Herbivore Susceptibility

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT High planting densities expose field crops to competition for light, which typically induces shade avoidance responses such as stem elongation. While adaptive in natural environments, these responses can lower yield and increase susceptibility to stress in agricultural systems.

Cytokinin downregulates Photosystem II photochemistry during prolonged darkness in a phytochrome B‐dependent manner

New Phytologist, Volume 250, Issue 6, Page 3846-3866, June 2026.
Cytokinin–phyB signaling modulates PSII photochemistry during prolonged darkness. Summary Cytokinins (CKs) delay dark‐induced senescence, but how they tune photosynthetic function in darkness remains unclear. We investigated the effects of classical aromatic CK benzylaminopurine and CK‐derived compound 1‐(2‐methoxyethyl)‐3‐(1,2,3‐thiadiazol‐5‐yl)urea ...
