Plant respiration at night is assumed to be temperature-controlled. Here, the authors show that temperature controls less than half of the variation in leaf respiration rate at night, and demonstrate how to account for such nocturnal variation in bio

Temperature varies on a daily and seasonal scale and thermal fluctuations are predicted to become even more pronounced under future climate changes. Studies suggest that plastic responses are crucial for species' ability to cope with thermal stress i

Leaf daytime respiration (leaf respiration in the light, RL) is often assumed to constitute a fixed fraction of leaf dark respiration (RD) (i.e. a fixed light inhibition of respiration (RD)) and vary diurnally due to temperature fluctuations. These a

Main conclusion Higher acclimated freezing tolerance improved winter survival, but reduced reproductive fitness of Arabidopsis thaliana accessions under field and controlled conditions. Abstract Low temperature is one of the most important abiotic fa

Measuring Freezing Tolerance of Leaves and Rosettes: Electrolyte Leakage and Chlorophyll Fluorescence Assays

Quantitative assessment of freezing tolerance is essential to unravel plant adaptations to cold temperatures. Not only the survival of whole plants, but also impairment of detached leaves or small rosettes after a freeze-thaw cycle can be used to acc
