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.

A new measurement of the neutron detection efficiency for the NaI Crystal Ball detector [PDF]

open access: yes, 2015
We report on a measurement of the neutron detection efficiency in NaI crystals in the Crystal Ball detector obtained from a study of single p0 photoproduction on deuterium using the tagged photon beam at the Mainz Microtron.

Modulation of SAL retrograde signalling promotes yield and water productivity responses in dynamic field environments

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1219-1233, February 2026.
Summary Chloroplast‐to‐nucleus retrograde signalling enables rapid stress responses in plants, but whether these signals accumulate to affect crop performance across entire growing seasons under field conditions remains unknown. We generated wheat mutants with targeted deletions in specific SAL gene copies from two distinct homeologous groups (TaSAL1 ...

Effects of the adiponectin mimetic compound ALY688 on glucose and fat metabolism in visceral and subcutaneous rat adipocytes

open access: yesAdipocyte, 2020
Adiponectin regulates white adipose tissue (WAT) metabolism and promotes insulin-sensitizing and anti-atherosclerotic effects in vivo. In this context, small molecule adiponectin receptor agonists have become of great therapeutic value for the treatment ...

Future heatwave conditions inhibit CO2‐induced stomatal closure in wheat

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1234-1252, February 2026.
Summary As global temperatures and the severity of droughts continue to increase, food crops will more frequently experience high vapour pressure deficit (VPD) during heatwave events. However, the interactive effects of rising atmospheric CO2 and high‐VPD heatwaves on crop water fluxes and yields are currently unknown.
