L. Havel; D. J. Durzan International Journal of Plant Sciences 1996. doi:10.1086/297315
Other claims from this paper (7)
- Observation Specific nuclei were eliminated during diploid parthenogenesis.
- Observation Nuclei became pycnotic and fragmented.
- Mechanism Apoptosis involved endonuclease activation and cell death.
- Method / resource TUNEL stained apoptotic nuclei red.
- Mechanism Nuclear degradation products were postulated to improve embryo survival, growth, and multiplication.
- Observation Nonapoptotic embryonal nuclei fluoresced strongly with DAPI.
- Observation Nuclei reacted blue with Giemsa in TUNEL-probed cells.
