Other claims from this paper (10)
- Observation Endosperm nuclei alternate between periods of DNA replication and non-replication.
- Observation Seven rounds of DNA replication occurred in some nuclei in later developmental stages.
- Observation DNA replication averaged approximately one round per 24-hour period.
- Observation The DNA levels in the nuclei showed an exact doubling pattern indicating endoreduplication.
- Observation Polytenization of the chromatin occurred to varying extents among the nuclei of the endosperm.
- Association A weak positive correlation existed between DNA content and size of nuclei.
- Association DNA increases and nuclear growth may not be highly coordinated in this tissue.
- Observation Average DNA content per nucleus across the endosperm peaked at approximately 12.8 C at 15 dap.
- Observation Average DNA content per nucleus increased 2.7-fold from 8 dap to the 15 dap peak.
- Observation Characteristics of nuclear populations from different kernels on the same ear showed minimal variation.
