Integration of light quality signals regulates ABA abundance and stomatal movements during seedling establishment

New Phytologist, Volume 249, Issue 3, Page 1253-1267, February 2026.
Summary Obtaining sufficient light for photosynthesis and avoiding desiccation are two key challenges faced by seedlings during early establishment. Perception of light quality via specialised photoreceptors signals the availability of sunlight for photosynthesis.

Superconductor strip with transport current: Magneto-optical study of current distribution and its relaxation [PDF]

, 2001
The dynamics of magnetic flux distributions across a YBaCuO strip carrying transport current is measured using magneto-optical imaging at 20 K. The current is applied in pulses of 40-5000 ms duration and magnitude close to the critical one, 5.5 A. During

A review of electronic portal imaging devices (EPIDs) [PDF]

Medical Physics, 1992
On‐line electronic portal imaging devices are beginning to come into clinical service in support of radiotherapy. A variety of technologies are being explored to provide real‐time or near real‐time images of patient anatomy within x‐ray fields during treatment on linear accelerators.

Calcium signaling in crops

New Phytologist, Volume 249, Issue 4, Page 1644-1658, February 2026.
Summary Calcium (Ca2+) signaling is integral to nearly all aspects of plant biology, including development and responses to biotic and abiotic stresses. It operates through two main layers: the generation of Ca2+ signals and their decoding by Ca2+‐binding proteins, which act early in diverse signaling pathways. The system exhibits remarkable robustness

Root cell wall plasticity in iron homeostasis: an overlooked frontier in plant nutrition

New Phytologist, Volume 249, Issue 4, Page 1699-1708, February 2026.
Summary Iron (Fe) is an essential micronutrient for plant growth and development, yet its availability in soils is often limited or excessive, leading to widespread Fe deficiency or toxicity that constrains crop productivity. While Fe uptake, transport, and signaling pathways have been well characterized, the role of the root cell wall as a dynamic ...
