Summary:
Endopolyploidy (EP) is a programmed process where cells multiply their genome without subsequent cell division. For many plant species, EP likely contributes to the development of their vegetative parts, yet its exact role in plant growth and adaptation to specific ecological settings remains speculative. This is mainly due to the plastic nature of EP, which challenges its accurate quantification and cross-species comparison, the lack of anatomical observations of EP cell occurrence, and the absence of experimental proof for suggested EP functions.
In this project, we will screen EP using a standard methodology in the largest species sample to date from several plant groups (Spring ephemerals, alpine plants, succulents). In selected species, we will preform detailed anatomical observations of EP cells occurrence and the growth-related anatomical traits to test several of our new ideas about EP function in plants. The validity of these ideas will be tested in two manipulative experiments. We will quantify EP and detect EP cells in selected tissue and ecological plant groups and identify the function and biological role of EP in these groups and verify it in manipulative experiments.
