Revisiting the two-layer hypothesis: coexistence of alternative functional rooting strategies in savannas. [PDF]
PLoS ONE, 2013 The two-layer hypothesis of tree-grass coexistence posits that trees and grasses differ in rooting depth, with grasses exploiting soil moisture in shallow layers while trees have exclusive access to deep water.

Systematic Biology, 2012 The estimation of phylogenetic relationships is an essential component of understanding evolution. Accurate phylogenetic estimation is difficult, however, when internodes are short and old, when genealogical discordance is common due to large ancestral effective population sizes or ancestral population structure, and when homoplasy is prevalent ...

Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]
, 2009 We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page in J Appl Ecol 11:773–781, (1974). A

The Arabidopsis Book, 2014 Roots hairs are cylindrical extensions of root epidermal cells that are important for acquisition of nutrients, microbe interactions, and plant anchorage. The molecular mechanisms involved in the specification, differentiation, and physiology of root hairs in Arabidopsis are reviewed here.

Influence of Auxins on Rooting Efficacy in Carnation (Dianthus caryophyllus L.) Cuttings
Journal of Horticultural Sciences, 2014 Effect of various auxins (IBA, IAA and NAA) on different types of cuttings was investigated to determine efficacy of auxins in promoting rooting in carnation (Dianthus caryophyllus L.).

Effects of some plant growth promoting rhizobacteria (PGPR) on rooting of grapevine rootstocks
Acta Agrobotanica, 2013 In this study. effects of topical applications of two plant growth promoting rhizobacteria (PGPR) strains and their combination (Bacillus BA16, OSU142 and BA16+OSU142) on the rooting of 41B and Rupestris du Lot rootstocks were investigated. The results

, 2006 A wide range of counting and occurrence constraints can be specified with just two global primitives: the Range constraint, which computes the range of values used by a sequence of variables, and the Roots constraint, which computes the variables mapping onto a set of values. We focus here on the Roots constraint.
