Tracking Sodium Inside the Plant: Hydraulic Adjustments to Deal With Salinity

open access: yesJournal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
ABSTRACT Sorghum is a crop that has become more relevant in recent years due to its uses and properties (biofuel, gluten‐free flour) as well as its versatility to grow in unfavourable environmental conditions. Salinity is one of the main abiotic stresses affecting crop production and yield worldwide.

Good days, bad days: Weather patterns driving bryophyte carbon‐exchange dynamics in tropical rainforest canopies

open access: yesFunctional Ecology, Volume 40, Issue 10, Page 3260-3275, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The physiology of tropical mosses, liverworts and lichens may be challenged by the daily weather patterns in lowland rainforests. Since these poikilohydric organisms can only photosynthesize and respire when hydrated, unfavourable timing of light and water availability (
