Phytohormones Action on Fouquieria Splendens Callogenesis and Organogenesis Processes
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 7, Issue 2
Abstract
It is known that callus can be produced from a single differentiated cell and many callus cells could be totipotent and able to regenerate a whole plant considering that high plasticity is the principal characteristic for their differentiation as a product of the particularly gene expression profiles; produced when the balance between cytokinins and auxins determines the state of differentiation and dedifferentiation. This work analyzed the effect of different actions of two cytokinins: bencil amino purine (BAP) and kinetin (KIN) and the naphthalene acetic acid (NAA) auxin on growth and morphological changes in the desert plant Fouquieria splendens callus. There were two evident morphological process determined not only by the Callus Induction Frequency (CIF) obtained, showing a great initial callus induction and after a good callogenesis and organogenesis processes; it also implies an active role in plant morphogenesis of F. splendens, by the cytokinin/auxin combination tested, showed by the scanning electron microscopy analysis, where a particularly presence of extracellular matrix surface network was present considering an important morphoregulatory structure during organogenesis process; showing not only a fast induction of calli and also a remarkably effect of growth and differentiation response of this interesting desert plant species.
