Nanocomposite Reduces Volatile and Aqueous Reactive Nitrogen Losses From Soil Compared to Conventional and Alternative Fertilisers

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Reactive nitrogen losses from agriculture contribute substantially to greenhouse gas emissions, water pollution and ecosystem degradation. Controlled‐release fertiliser technologies offer potential solutions, yet few comprehensively evaluate performance across multiple nitrogen loss pathways and soil types.

Comparison of Uptake of Cadmium at Low Concentrations Under Hydroponic and Soil‐Based Agriculture Systems for Lettuce, Indian Spinach and Methi

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Using recycled water for agriculture offers a sustainable approach by adding inherent nutrients and moisture to the soil. However, it contains unwanted contaminants such as heavy metals like cadmium at lower concentrations. This study assessed the comparative response of three leafy crops ‐ lettuce, Indian spinach and methi, against cadmium ...

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

open access: yesThe FEBS Journal, Volume 293, Issue 6, Page 1681-1707, March 2026.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Revisiting the relationship between stomatal size and speed across species – a meta‐analysis

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.
