Transport of the two natural auxins, indole-3-butyric acid and indole-3-acetic acid, in Arabidopsis.
Polar transport of the natural auxin indole-3-acetic acid (IAA) is important in a number of plant developmental processes. However, few studies have investigated the polar transport of other endogenous auxins, such as indole-3-butyric acid (IBA), in Arabidopsis. This study details the similarities and differences between IBA and IAA transport in several tissues of Arabidopsis. In the infloresce...
The present study explores the potential of exogenous auxins in the development of adventitious shoots and roots from shoot cuttings of Couroupita guianensis (Nagalingam), a threatened tree. Experiments were conducted to assess the effect of various concentrations of auxins on shoot and root morphological traits of stem cuttings in the greenhouse. Amongst the auxins tested, significant effects ...
Transformed hairy roots induced on Solanum dulcamara plants by Ri plasmid of Agrobacterium rhizogenes strain 8196 and A4T, exhibited a higher levels of auxin and cytokinin activity as compared with that of non transformed control roots. Endogenous pbytohormones; auxins and cytokinins were determined in an ethyl acetate fractionated extracts using bioassay methods of Hordium coleoptile test for ...
In plants, the mechanisms that regulate the transit of vacuolar soluble proteins containing C-terminal and N-terminal vacuolar sorting determinants (VSDs) to the vacuole are largely unknown. In a screen for Arabidopsis thaliana mutants affected in the trafficking of C-terminal VSD containing proteins, we isolated the ribosomal biogenesis mutant rpl4a characterized by its partial secretion of va...
In this study, callus of P. tunicoides was used to induce adventitious roots. It was found that the medium with indole-3-butyric acid (IBA) was most suitable for induction of P. tunicoides adventitious roots from callus. To investigate the effects of concentration and type of auxins on adventitious roots induction, an orthogonal test was deployed. It was shown that 2,4Dichlorophenoxyacetic acid...
