Track cytokinin effects
Cytokinins promote cytokinesis, lateral-bud outgrowth and chloroplast development, and can delay senescence. Together with auxin, they stimulate callus proliferation in culture.
Remember kinetin
Kinetin was isolated in crystalline form from autoclaved herring-sperm DNA preparations. Natural cytokinins such as zeatin are adenine derivatives.
OlympIQ exam lens
- ✓Cytokinin: cell division and lateral buds.
- ✓Cytokinin promotes chloroplast formation and delays senescence.
- ✓Auxin + cytokinin stimulate callus growth.
OlympIQ trap
Cytokinin often counteracts auxin-driven apical dominance.
