Suppression of annual grasses may also involve root competition other than nutrient depletion whence perennial roots simply occupy biological soil space and, through chemical signalling, allelopathy included, may forestall competing roots from entering their space (Monk and Gabrielson 1985; McConnaughay and Bazzaz 1992; Schenk 2006).
However, changes in the rooting of haplotype networks do not always involve root switching.
Thus, a step in the process of the acquisition of microbes by roots may involve 'corralling' microbes at the root surface by cell wall-like outgrowth for subsequent incorporation.
Therefore, the Pistarv response may involve CPL3 to govern root hair patterning.
In kyphoplasty and vertebroplasty procedures, PMMA cement may leak laterally to the soft tissues, superiorly or inferiorly into the adjacent disc space, or posteriorly, where it may involve the exiting nerve root or the spinal canal [ 26].
Phosphorus deficiency typically leads to an increase in the root : shoot ratio and while this may involve an absolute increase in root biomass under mild P deficiency, more severe P or Zn deficiency typically leads to an absolute decrease in root biomass (Wissuwa and Ae, 2001 a, b ) and the increasing root : shoot ratio would thus be due to a proportionally larger decline in shoot biomass.
These lesions are completely different; however, they may involve the spinal nerve roots or the major nerve trunks.
Addressing the root cause may involve modification of the design or the manufacturing processes.
The findings reported here suggest that part of the molecular mechanism(s) by which ABA/auxin cross-talk occurs during regulation of root development may involve regulation of auxin biosynthesis and transport genes in response to ABA levels.
These findings suggest that part of the molecular mechanism(s) by which ABA and auxin interact during regulation of Arabidopsis root development may involve regulation of auxin homeostasis and/or transport by ABA levels.
