Organogenesis is an important process for plant regeneration by tissue or cell mass differentiation to regenerate a complete plant. MicroRNAs (miRNAs) play an essential role in regulating plant development by mediating target genes at transcriptional and post-transcriptional levels, but the diversity of miRNAs and their potential roles in organogenesis of Acacia crassicarpa have rarely been inv...
Transverse thin cell layer sections excised from in vitro scales of Lilium ledebourii were cultured on Murashige and Skoog (MS) medium supplemented with various plant growth regulators (PGRs) at different concentrations. Although, bulblets were produced on PGRfree MS medium during organogenesis, addition of 0.25 mg l-1 6-benzyladenine or 5.0 mg l-1 indole-3-acetic acid to the medium increased t...
the present study was aimed at the development of a somoclonal variant and isozyme marker for phyllanthus amarus schum & thonn using inter-nodal segments and the enzyme peroxidase. maximum callus proliferation was obtained on murashige and skoog’s medium supplemented (ms) with 1.0 mg/l of 2,4-dichlorophenoxyacetic acid. three weeks-old pale yellowish white semi-friable callus was used for o...
Postembryonic de novo organogenesis represents an important competence evolved in plants that allows their physiological and developmental adaptation to changing environmental conditions. The phytohormones auxin and cytokinin (CK) are important regulators of the developmental fate of pluripotent plant cells. However, the molecular nature of their interaction(s) in control of plant organogenesis...
Plants, unlike animals, possess a unique developmental plasticity, that allows them to adapt changing environmental conditions. A fundamental aspect of this plasticity is their ability undergo postembryonic de novo organogenesis. This requires the presence regulators trigger and mediate specific spatiotemporal changes in programs. The phytohormone cytokinin has been known as principal regulator...
