Model Organisms

Last changed: 04 January 2020

Our main model organisms are Arabidopsis thaliana and Norway spruce (Picea abies). Combination of an angiosperm and a gymnosperm models enables evolutionary interpretation of our findings.

A gradient of programmed cell death along apical-basal axis of a Norway spruce embryo (from left to right), which is composed of a living embryonal mass (EM) and several layers of suspensor cells with increased degree of disassembly towards basal pole of the embryo. This model system provides a powerful paradigm for studying mechanisms of developmental cell death.
