Insertion and deletion (indel)-based analyses have great potential for rooting the tree of life, but their use has been limited because they require ubiquitous sequences that have not been horizontally/laterally transferred. Very few such sequences exist. Here we describe and demonstrate a new algorithm that can use nonubiquitous sequences for rooting. This algorithm, top-down indel rooting, us...

Studies have shown that rooting substrate is one of the effective factors at rooting of hard rhizogenetic plant such as Henna. The purpose of this study is to determine an appropriate concentration of Naphthalene Acetic Acid (NAA), Indole Butyric Acid (IBA) and salicylic acid (SA) on Rooting of Henna. Present study showed that there was a great variation in most of the measured characters at P<...

The gerbera market would benefit from an efficient and simple protocol for high rate regeneration for propagation and genetic engineering. With these objectives, this investigation was done on shoot regeneration via direct organogenesis from leafy petiole explants of Gerbera jamesonii ‘Royal Soft Pink’. Murashige and Skoog (1962) (MS) medium was supplemented with 0.1 mg L-1 indole-3-acetic acid...

An efficient protocol was established for rapid in vitro propagation of Stevia rebaudiana Bertoni, using explants from mature plants. The effect of 1/2MS, MS and B5 culture media, also 27 different combinations of auxins and cytokinins was studied on in vitro growth and development of Stevia rebaudiana Bertoni. The best culture medium for shoot and root formation was 1/2MS, producing 1.30 shoot...

In vitro rooting and the acclimatization of micropropagated rootstocks of apple trees is essential for plant development in the field. The aim of this work was to assess the use of rhizobia of Adesmia latifolia to promote rooting and acclimatization in micropropagated Marubakaido apple rootstock. An experiment involving in vitro rooting and acclimatization was performed with four strains of rhi...

Peroxidases play a major role in several physiological processes. Specifically, in vitro activity of this enzyme was used as a marker to identify different rooting phases of Nothofagus. The study of peroxidase profile patterns during rhizogenesis in this genus could give additional information about this topic, to justify the use of peroxidase isoforms as a more specific biochemical marker than...

one of the fundamental processes in woody plant propagation especially olive is rooting ability of cuttings. thus the selection of superior trees with desirable genetic structure is essential. adventitious root formation is a key step in rooting ability. therefore, identification of inducible genes in these processes is necessary. in this study, for the first time importin genes were identified...

Rooting phylogenies is critical for understanding evolution, yet the importance, intricacies and difficulties of rooting are often overlooked. For rooting, polymorphic characters among the group of interest (ingroup) must be compared to those of a relative (outgroup) that diverged before the last common ancestor (LCA) of the ingroup. Problems arise if an outgroup does not exist, is unknown, or ...

Progress and problems in vegetative propagation of important North American hardwoods are reviewed with emphasis on rooting cuttings and the application of propagatIOn t~'hniqucs in breeding research. Some problems in rooting physiology are diS('u,;",>.
