Abstract Light respiration (RL) is an important component of plant carbon balance and a key parameter in photosynthesis models. RL often measured using the Laisk method, gas exchange technique that traditionally employed under steady-state conditions. However, nonsteady-state dynamic assimilation (DAT) may allow for more rapid measurements. In 2 studies, we examined efficacy DAT estimating Ci* (the intercellular CO2 concentration where Rubisco's oxygenation velocity twice its carboxylation...
Abstract Wheat photosynthetic heat tolerance can be characterized using minimal chlorophyll fluorescence to quantify the critical temperature (Tcrit) above which incipient damage machinery occurs. We investigated intraspecies variation and plasticity of wheat Tcrit under elevated in field controlled-environment experiments, assessed whether mirrored interspecific patterns global tolerance. In field, varied diurnally—declining from noon through sunrise—and increased with phenological...
Plant metabolism faces a challenge of investing enough enzymatic capacity to pathway without overinvestment. As it takes energy and resources build, operate, maintain enzymes, there are benefits drawbacks accurately matching the influx. The relationship between functional physiological load could be explained through symmorphosis, which would quantitatively match Alternatively, plants excess manage unpredictable In this study, we use photorespiration as case study investigate these two...
Abstract Heat-induced inhibition of photosynthesis is a key factor in declining wheat performance and yield. Variation heat tolerance can be characterised using the critical temperature ( T crit ) above which incipient damage to photosynthetic machinery occurs. We investigated intraspecies variation plasticity under elevated field controlled environment experiments. also assessed whether mirrors patterns global interspecies reported for mostly wild, woody plants. In field, varied through...
