- Observation Following fertilisation the Arabidopsis zygote divides asymmetrically to generate apical and basal lineages, establishing the apical-basal axis that defines future shoot and root poles.
- Mechanism Analyses of classical mutants (gnom, monopteros, bodenlos, topless) showed that localised auxin biosynthesis, directional transport and downstream transcriptional responses are central to apical-basal axis establishment and organ initiation.
- Observation Fluorescence-compatible clearing reagents and three-dimensional reconstructions now permit quantitative analyses of cell geometry, division orientation and cytoskeletal dynamics in Arabidopsis embryogenesis.
- Observation Live ovule imaging setups with confocal laser scanning and multiphoton microscopes enable real-time observation of Arabidopsis embryo development.
- Observation Laser-assisted cell ablation can be used to probe cell-to-cell communication and fate plasticity in Arabidopsis embryos.
