However, in the current experiment plants maintained growth during the stress periods; presumably, the lateral roots become functional roots as demonstrated for pasture legumes (Gibberd et al. 1999).
The century-old myth of the noble savage may not be a complete myth after all, with nobility's functional roots being veiled in interior politics and overshadowed by their darker counterparts in exterior politics.
Future efforts should focus on important traits in rice, such as accelerated germination, faster shoot extension, ability to produce functional roots and leaves under flooded conditions, and probably ability of seedlings to develop aerenchyma tissue to aerate submerged plant parts at earlier stages.
An appropriate functional root description can contribute to targeted cover crop selection for efficient runoff mitigation.
Several structural functional root models have been published (e.g. SimRoot, Lynch et al. [1997] and R-SWMS, Dunbabin et al. [2013]) as well as other soil models (Reviewed in Hill et al. [2013]).
In root development, phenotypic defects were revealed only for triple pin1 pin3 pin4 mutants having very short root and for quadruple pin1 pin3 pin4 pin7 mutants, which, depending on the ecotype, either are embryo lethal with pronounced root pole abnormalities or develop into seedlings with no root or a non-functional root (Friml et al., 2003).
Root functional traits including root mass density (RMD), root length density (RLD) and percentage of fine roots were measured on all individuals.
For example, experiments in which the QC cells has been ablated, verified the reappearance of an auxin maximum just above the ablated tissue, leading to the reestablishment of a functional stem cell niche and root patterning on remarkably short biological time-scales [ 52].
However, unlike AtSPL8 being functional in roots, the soybean homologs were not expressed in roots, resembling that of tomato SPL8 homologs [ 64].
At this last stage, intraspecific competition for resources (light and nutrients) increases, inducing a density reduction in the aerial stand (i.e., self-thinning), but root systems of altruistic individuals could remain functional via root grafting.
Bullying is not anti-social behavior, but rather is both intensely social and functional behavior rooted in the school and larger cultural value systems.
