The effect of increasing temperature on crop photosynthesis: from enzymes to ecosystems

Journal of Experimental Botany · 2021 · 574 citations

As global land surface temperature continues to rise and heatwave events increase in frequency, duration, and/or intensity, our key food and fuel cropping systems will likely face increased heat-related stress. A large volume of literature exists on exploring measured and modelled impacts of rising temperature on crop photosynthesis, from enzymatic responses within the leaf up to larger ecosystem-scale responses that reflect seasonal and interannual crop responses to heat. This review discusses…

Assessing the Impact of Agrivoltaics on Water, Energy, and Carbon Cycles Using the Community Land Model Version 5

Journal of Advances in Modeling Earth Systems · 2026-01-29 · 4 citations

Abstract Agrivoltaics, combining agriculture with photovoltaic systems, offers a promising solution to address land‐use conflict between food and energy production. However, the complexities of agrivoltaics and its effects on the water‐energy‐carbon interactions remain poorly understood. In this study, we developed a process‐based agrivoltaic model within the Community Land model 5 to assess the impacts of agrivoltaics on water, energy, and carbon cycles. The model was validated using data from…

Bigger is not always better: Optimizing leaf area index with narrow-leaf shape in soybean

PLANT PHYSIOLOGY · 2025-12-24 · 3 citations

Modern soybean (Glycine max) varieties have higher than optimal leaf area index (LAI), which could divert resources from reproductive growth. Altering leaf shape could be a simple strategy to reduce LAI. To test this, we developed 204 near-isogenic lines differing in leaf morphology by introgressing the ln allele that confers the narrow-leaf trait from 2 donor parents (PI 612713A and PI 547745) into the elite, broad-leaf cultivar LD11-2170. We evaluated the lines across 2 locations and 2 row spa…

N ₂ Onet: a global collaborative network facilitating advances in measurement, modeling, and mitigation of agricultural soil nitrous oxide emissions

Environmental Research Letters · 2026-02-10 · 1 citations

Abstract Nitrogen (N) fertilizer supports global food production, but its use and overuse drive emissions of nitrous oxide (N 2 O), a potent and long-lived greenhouse gas. Understanding the drivers of N 2 O fluxes remains elusive, making it difficult to predict emissions in time and space and to develop and evaluate ways to lower emissions through management. Major scientific uncertainties underlying the understanding of the drivers of N 2 O fluxes identified in a workshop of N 2 O emissions exp…
