Greater Than the Sum of the Parts: Revisiting the Enhancement Effect in Photosynthesis Using Simulated Sun‐ and Shade‐Light

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Far‐red light (FR) alone drives photosynthesis poorly, but when combined with shorter wavelengths it enhances photosynthesis beyond the sum of their individual effects—a phenomenon known as the Emerson enhancement effect. This effect is well‐established for narrowband PAR‐FR mixtures, and recent results show it also occurs within broadband ...

Structural Basis of Sequential Enantioselective Epoxidation by a Flavin‐Dependent Monooxygenase in Lasalocid A Biosynthesis

open access: yesAngewandte Chemie, Volume 137, Issue 24, June 10, 2025.
Lsd18 is a flavin‐dependent monooxygenase from Streptomyces lasalocidi that performs two enantioselective epoxidations during lasalocid A biosynthesis. X‐ray crystal structures of Lsd18 bound to a substrate and product analogue illuminate how this enzyme performs multiple epoxidations on the same substrate molecule and how it controls stereoselectivity.

Tolerance to Phosphorus Deficiency Improves Seed Phytic Acid‐to‐Iron Molar Ratios in Common Bean

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Although significant advances have been achieved in the biofortification of common beans to overcome deficiencies in Zinc (Zn) and iron (Fe), the mechanisms involved remain poorly understood. We thus explored the relationships between phosphorus nutrition and Zn and Fe accumulation in four bean genotypes (Edar, Nizok, Colorado and Chimbolos ...

Zusammenhang zwischen Transhydrogenase- und Diaphorase-Aktivität der Ferredoxin-NADP-Reduktase und der photosynthetischen NADP-Reduktion / Relationship of Transhydrogenase and Diaphorase Activity of Ferredoxin-NADP Reductase with Photosynthetic NADP Reduction

open access: yesZeitschrift für Naturforschung B, 1971
Photosynthetic NADP reduction, diaphorase and transhydrogenase activity of ferredoxin-NADP reductase (EC 1.6.99.4 or 1.6.1.1, from the alga Bumilleriopsis filiformis) are compared by studying the influence of pyridine nucleotides and 2'-AMP. Together with previous findings dealing with the role of ferredoxin in the two latter activities 7 the results ...

Sensory Perception of Fluctuating Light in Arabidopsis

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT When exposed to shade from neighbours, competitive plants modify their growth patterns to improve access to light. In dense plant stands, ranging from forests to humid grasslands and crops, shade is interrupted by sunflecks penetrating the canopy. Relatively infrequent, minute‐scale interruptions can significantly contribute to the daily light

Hexose-6-phosphate dehydrogenase modulates the effect of inhibitors and alternative substrates of 11[beta]-hydroxysteroid dehydrogenase 1 [PDF]

open access: yes, 2008
Intracellular glucocorticoid reactivation is catalyzed by 11[beta]-hydroxysteroid dehydrogenase 1 (11[beta]-HSD1), which functions predominantly as a reductase in cells expressing hexose-6-phosphate dehydrogenase (H6PDH).

Plastids in a Pinch: Coordinating Stress and Developmental Responses Through Retrograde Signalling

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plastids are crucial for fuelling and regulating plant growth and development. Photosynthesising chloroplasts provide energy for growth, while other plastids play additional key roles in various aspects of plant physiology. For function and development, plastids greatly depend on nucleus‐encoded proteins, and they can modulate the synthesis of

Transcriptomic analysis of the mandibular gland genes associated with reproductive dominance in Apis mellifera capensis Esch. parasitic workers

open access: yesPhysiological Entomology, EarlyView.
Biosynthesis of the fatty acid components of the Apis mellifera mandibular gland pheromones takes place in a stepwise manner. Differential gene expression in the mandibular gland tissue of workers from two subspecies of African honey bees with differing reproductive potentials and at two age groups was investigated.

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Effects of Dietary Anise (Pimpinella anisum L.) Oil on Growth Performance, Blood Parameters and Muscle Nutrient Content of Nile Tilapia (Oreochromis niloticus)

open access: yesVeterinary Medicine and Science, Volume 11, Issue 4, July 2025.
This study investigates the dietary inclusion of anise oil (Pimpinella anisum L.) in Nile tilapia (Oreochromis niloticus) feed and its impacts on growth performance, haematological indices and muscle nutrient composition. Supplementation with 0.10%–0.20% anise oil significantly enhanced fish growth, improved blood health indicators and increased muscle
