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 ...

Macronutrient composition in pollen affects development and survival in wild bees

Physiological Entomology, Volume 51, Issue 2, Page 350-362, June 2026.
Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival. Macronutrient analyses on both pollen types revealed dandelion pollen contained lower levels of protein, essential amino acids and several fatty acids, which ...

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.
