Mineral nutrition and adventitious rooting in microcuttings of Eucalyptus globulus.
We characterized the adventitious rooting response of Eucalyptus globulus Labill. to various concentrations of calcium, nitrogen, phosphorus, iron, manganese, zinc, boron and copper. The parameters analyzed were percent rooting, root number, root length and mean rooting time. Root number and root length were significantly affected by mineral nutrition, whereas mean rooting time and rooting perc...
متن کاملAuxin and ethylene promote root hair elongation in Arabidopsis.
Genetic and physiological studies implicate the phytohormones auxin and ethylene in root hair development. To learn more about the role of these compounds, we have examined the root hair phenotype of a number of auxin- and ethylene-related mutants. In a previous study, Masucci and Schiefelbein (1996) showed that neither the auxin response mutations aux1 and axr1 nor the ethylene response mutati...
متن کاملiTRAQ-Based Proteomic Analysis Reveals Potential Regulation Networks of IBA-Induced Adventitious Root Formation in Apple
Adventitious root (AR) formation, which is controlled by endogenous and environmental factors, is indispensable for vegetative asexual propagation. However, comprehensive proteomic data on AR formation are still lacking. The aim of this work was to study indole-3-butyric acid (IBA)-induced AR formation in the dwarf apple rootstock 'T337'. In this study, the effect of IBA on AR formation was ana...
متن کاملAuxin controls Arabidopsis adventitious root initiation by regulating jasmonic acid homeostasis.
Vegetative shoot-based propagation of plants, including mass propagation of elite genotypes, is dependent on the development of shoot-borne roots, which are also called adventitious roots. Multiple endogenous and environmental factors control the complex process of adventitious rooting. In the past few years, we have shown that the auxin response factors ARF6 and ARF8, targets of the microRNA m...
متن کاملStem segments of apple microcuttings take up auxin predominantly via the cut surface and not via the epidermal surface
In conventional cuttings, auxin applied to achieve rooting is taken up predominantly via the cut surface and not via the epidermal surface of the stem. Even though in tissue-cultured plants the cuticle is poorly developed and the stomata do not function properly, stem segments of apple microcuttings took up labelled indoleacetic acid also predominantly via the cut surface. Stem segments with an...
