Statistical modeling of nitrogen-dependent modulation of root system architecture in Arabidopsis thaliana

Epistatic genetic architecture of root length in Arabidopsis thaliana Authors

Efforts to identify loci underlying complex traits generally assume that most genetic variance is additive. This is despite the fact that non-additive genetic effects, such as epistatic interactions and developmental noise, are also likely to make important contributions to the phenotypic variability. Analyses beyond additivity require additional care in the design and collection of data, and i...

Signalling mechanisms underlying the morphological responses of the root system to nitrogen in Arabidopsis thaliana.

Plants display considerable developmental plasticity in response to changing environmental conditions. The adaptations of the root system to variations in N supply are an excellent example of such developmental plasticity. In Arabidopsis, four morphological adaptations to the N supply have been characterized: (i) a localized stimulatory effect of external nitrate on lateral root elongation; (ii...

RootScape: A landmark-based system for rapid screening of root architecture in Arabidopsis thaliana

Nitrate-responsive miR393/AFB3 regulatory module controls root system architecture in Arabidopsis thaliana.

One of the most striking examples of plant developmental plasticity to changing environmental conditions is the modulation of root system architecture (RSA) in response to nitrate supply. Despite the fundamental and applied significance of understanding this process, the molecular mechanisms behind nitrate-regulated changes in developmental programs are still largely unknown. Small RNAs (sRNAs)...
