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 ...

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.).

, 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.

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.

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

Root Vertex Valency Distributions of Rooted Maps and Rooted Triangulations
European Journal of Combinatorics, 1994 We obtain the asymptotic distributions of root vertex valencies for rooted maps and rooted triangulations on general surfaces. We show that the asymptotic distributions are independent of the surface.

Taro Roots: An Underexploited Root Crop
Nutrients, 2023 Taro (Colocasia esculenta) is a root crop that remains largely underutilized and undervalued despite its abundance and affordability. In comparison to other root vegetables, such as potatoes, yams, carrots, and cassava, taro stands out as a plentiful and low-cost option.

"GALVANOTROPISM" OF ROOTS [PDF]
Journal of General Physiology, 1927 1. New experiments, made in such a way to eliminate as completely as possible products of polarization and the migration of such products when formed, have shown that the exhibition of galvanotropic curvature in roots is mainly dependent upon such products, since no curvature appears when they are excluded. 2.
