Annotation: Plants, unlike animals, possess a unique developmental plasticity that enables them to develop new organs throughout their entire life. This ability requires the presence of regulators that trigger specific spatiotemporal changes in developmental programs. In de novo shoot regeneration, cytokinins are the prime candidates for the signal that determines the shoot identity. The process is accompanied by changes in the metabolism, signalling and by differential regulation of gene expression.
The project will aim to elucidate the role and the impact of cytokinins during de novo shoot regeneration. A wide range of molecular biology methods will be used, mainly CRISPR/Cas9 system to generate mutants in cytokinin metabolic enzymes, as well as several cloning methodologies (Gibson assembly, Gateway etc.), in vitro cultivation, luciferase assay or microscopy and image analysis.
