Importance of Timing of Dark Acclimation for Estimating Light Inhibition of Leaf Respiratory CO2 Efflux

  • Pages: 3151-3158
  • First Published: 20 December 2024
SUMMARY STATEMENT

The degree of inhibition of leaf respiration by light is often studied, but the methods used and the results obtained are variable. We suggest that in the future daytime leaf respiration is measured 3 min after dark acclimation to avoid under-estimating the degree of light inhibition of leaf respiration. This will most likely speed up future surveys and perhaps also result in less inter-study variation in the calculated degree of light inhibition of leaf respiration.

Hydraulic Properties of a Rock-Soil-Root System: Insights From Fraxinus ornus L. Saplings Growing on Different Carbonate Rocks

  • Pages: 3448-3458

ICE1 (Inducer of CBF Expression 1) Is Essential for the Jasmonate-Regulated Development of Stamen in Arabidopsis thaliana

Summary statement

In Arabidopsis thaliana, jasmonic acid signalling promotes the degradation of JAZ proteins, relieving their inhibition on ICE1. Once activated, ICE1 regulates floral organ and pollen development by stimulating the expression of MYB21, MYB24 and MYB108.
