WebHybrids misexpressed endosperm and seed coat regulators and hyperactivated genes encoding ribosomal, photosynthetic, stress-related, and immune response proteins. Regulatory disruption was more severe in Columbia-0 hybrids than in C24 hybrids, consistent with the degree of incompatibility. WebIncompatible cytoplasm. In a few cases, embryo development may be blocked by an incompatibility between the cytoplasms of the species used as female and the genome of the species used as male. Such an interaction more generally, leads to hybrid weakness and male sterility in the hybrids. In a few cases, embryo development may also be prevented.
