A rapid and efficient in vitro propagation protocol of Acorus calamus L. an important endangered medicinal plant has been developed. Naturally grown rhizome segments were used as explants for initial culture. Surface sterilized rhizome segments were cultured on Murashige and Skoog (MS) medium supplemented with various concentrations (0.5 mg l 3.0 mg l ) of cytokinins (BAP, Kn) and auxins (IAA, ...

During the exploration of the soil by plant roots, uptake of water and nutrients can be greatly fostered by a regular spacing of lateral roots (LRs). In the Arabidopsis root, a regular branching pattern depends on oscillatory gene activity to create prebranch sites, patches of cells competent to form LRs. Thus far, the molecular components regulating the oscillations still remain unclear. Here,...

The research has been done for assessment of effects of different concentrations of Indole-3-Butyric Acid (IBA) on rhizogenesis of scions of C. Phlomidis in 2010.  The research has been done on Randomized Complete-blocks for five replications and three treatments with zero, 2000ppm and 3000pmm concentration. Different characters such as number of root of each scion, length of root, length of ne...

Abstract Female and male plants of difficult-to-root species Leucadendron elimense subsp. were investigated for rooting potential with three hormones: indole-3-acetic acid (IAA), 1-naphthaleneacetic (NAA), indole-3-butyric (IBA) at different concentrations (2000 ppm, 4000 6000 ppm). The experiment was made under essential misting, bottom heat, a naturally ventilated greenhouse. After 18 weeks t...

Differential distribution of the plant hormone auxin within tissues mediates a variety of developmental processes. Cellular auxin levels are determined by metabolic processes including synthesis, degradation, and (de)conjugation, as well as by auxin transport across the plasma membrane. Whereas transport of free auxins such as naturally occurring indole-3-acetic acid (IAA) is well characterized...

An internal standard, [(13)C][indole-2]-indole-3-butyric acid, was synthesized from indole-2[(13)C] and was shown to be effective for the quantitative determination of indole-3-butyric acid from plant tissue. When this standard was used along with [(13)C(6)]indole-3-acetic acid, both indolic auxins could be quantified from the same tobacco (Nicotiana tabacam) leaf sample by isotope dilution ana...

The induction of rooting in microshoots of Zingiber officinale cvs. Suprava, Turia local, Suruchi and V3S18 was achieved on half-strength basal Murashige and Skoog's medium supplemented with 0.5-1.0 mg/l either indole-3-acetic acid (IAA) or indole-3-butyric acid (IBA) and 2% (w/v) sucrose within 7-9 days of culture. Rooting was inhibited when the microshoots were cultured under higher concentra...

using apple clonal rootstocks is necessary for improving crop efficiency in apple orchards. after graftingof apple cultivars on malling rootstocks, the extra parts of the rootstock was used as stem cuttings. apical,middle and basal parts of these shoots were used as cuttings. two propagation conditions, greenhouse andnursery and three concentrations of indole-3- butyric acid (iba) on rooting, c...

Euryodendron excelsum H. T. Chang, a critically endangered species endemic to China, is source of valuable material for the furniture and construction industries. However, this has some challenges associated with rooting during in vitro propagation that have yet be resolved. In study, we optimized conducted transcriptomic analysis appreciate its molecular mechanism, thereby promoting practical ...
