Involvement of cytokinins in adventitious and lateral root formation
The root systems of higher plant consist of primary, lateral, and adventitious roots. There is a current hypothesis, named ‘root apical dominance’, that root-derived suppressor negatively regulates the formation of adventitious and lateral roots. According to this hypothesis, we have studied the mechanisms involved in the regulation of adventitious and lateral root formation. trans-zeatin ribos...
متن کاملAdventitious root formation in tree species: involvement of transcription factors.
Adventitious rooting is an essential step in the vegetative propagation of economically important horticultural and woody species. Populus has emerged as an experimental model for studying processes that are important in tree growth and development. It is highly useful for molecular genetic analysis of adventitious roots in trees. In this short review, we will highlight the recent progress made...
متن کاملBiochemical Basis of Adventitious Root Formation on Etiolated Stem Segments
Segments (2.5-cm-long) of Populus nigra L. obtained from etiolated axillary branches did not root in water or auxin alone, but rooted in 0.5% ribose, glucose and sucrose and more profusely with 0.1 mg/1 in dole-acetic acid (IAA) or in dolebutyric acid (IBA) added to the medium. 5-fluorodeoxyuridine (FUDR), 5-fluorouracil (FU), actinomycin-D and cycloheximide inhibited rooting. The deoxyribonucl...
متن کاملHormonal interplay during adventitious root formation in flooded tomato plants.
Soil flooding, which results in a decline in the availability of oxygen to submerged organs, negatively affects the growth and productivity of most crops. Although tomato (Solanum lycopersicum) is known for its sensitivity to waterlogging, its ability to produce adventitious roots (ARs) increases plant survival when the level of oxygen is decreased in the root zone. Ethylene entrapment by water...
متن کاملHypocotyl adventitious root organogenesis differs from lateral root development
Wound-induced adventitious root (AR) formation is a requirement for plant survival upon root damage inflicted by pathogen attack, but also during the regeneration of plant stem cuttings for clonal propagation of elite plant varieties. Yet, adventitious rooting also takes place without wounding. This happens for example in etiolated Arabidopsis thaliana hypocotyls, in which AR initiate upon de-e...
