...To address whether Ct helps plants to assimilate nutrients, we used an agarose gel-based medium in which the concentration of specific nutrients, such as phosphorus, nitrogen, and iron, can be tightly controlled (Gruber et al., 2013)....

...When nutrient-deficient plants are supplied with a heterogeneous nutrient environment, they activate a set of morphological and physiological responses called foraging (De Kroon et al., 2009; Gojon et al., 2009; Gruber et al., 2013; Hodge, 2004; Nacry et al., 2013)....

...…effect on lateral roots (LRs) depending on the concentration: (1) a stimulation of LR growth at limiting to sufficient N-supply ([NO3 -] <10mM) and (2) an inhibition of LR meristem activation at supraoptimal N-supply ([NO3 -] ≥10mM) (Gruber et al., 2013; Zhang and Forde, 1998; Zhang et al., 1999)....

...A strong shift from main root growth to lateral root growth is observed, which leads to a short root with a high number of long laterals (Figure 3A; Williamson, 2001; Linkohr et al., 2002; López-Bucio et al., 2002; Gruber et al., 2013)....

...However, low nitrate availability does not limit primary and lateral root elongation, enabling the root system to reach deeper layers of the soil (Figure 3B; Linkohr et al., 2002; Gruber et al., 2013)....
