Repeatable, continuous and real‐time estimates of coupled nitrogenase activity and carbon exchange at the whole‐plant scale Symbiotic nitrogen fixation (SNF) by higher plants and their bacterial symbionts is a globally important input of nitrogen. Our understanding of the mechanisms that control SNF and the time-scales...

We applied a novel method that we previously developed to measure N fixation in individual plants over the course of several weeks after inducing a drastic change in soil N supply. This method makes non-destructive measurements at the whole-symbiosis scale. doi.org/10.1111/2041...

Time lags in up-regulation varied by symbiotic type, with N fixation starting earlier in rhizobia symbioses but increasing faster once it started in actinorhizal symbioses.

Time lags in down-regulation varied by growing temperature and biome of origin.

Time lags are possibly long enough to hinder the competitive benefit of facultative N fixation and clearly long enough to cause high losses of plant-available N from forests with a relatively high abundance of N-fixing trees.

Time lags in the regulation of symbiotic nitrogen fixation Theory has shown that time lags in the regulation of symbiotic nitrogen (N) fixation (SNF) can be important to the competitive dynamics and ecosystem consequences of N-fixing trees, but measurements...
