Projekt
Hybridization barriers: CRP signalling during pollen tube invasion, growth and guidance (A03)
Subject Area
Plant Cell and Developmental Biology
Term
from 2011 to 2023
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 170483403
Flowering plants evolved pre-zygotic hybridization barriers to avoid foreign fertilization, and thus to prevent sterility effects caused by fertilization defects and genome imbalance failures. The Dresselhaus lab and others have shown that small polymorphic cysteine-rich peptides (CRPs) play key roles as signalling ligands in the underlying communication processes. Novel CRPs and activated signalling pathways identified recently in maize will be studied in more detail and transferred to other species to understand and overcome pre-zygotic hybridization barriers for breeding.
