Other claims from this paper (12)
- Method / resource Mildly fixed maize microsporocytes frequently yielded cytoplasm-free chromosomes.
- Method / resource Knobs and heterochromatin were clearly visible by electron microscopy.
- Method / resource The electron microscopic map can be aligned with the traditional cytological map.
- Observation Chromosome 6 was frequently associated with the nucleolus.
- Observation Electron-dense regions appeared on each synapsing homolog at zygotene.
- Observation During synapsis, homolog bands aligned into more conspicuous bands.
- Observation Early pachytene banding was stable and reproducible.
- Observation Chromosome 6 contained eight dark bands.
- Observation Chromosome 6 contained 19 medium bands.
- Observation Chromosome 6 contained 14 light bands.
- Method / resource The bands may serve as regional gene mapping markers.
- Observation Adjacent chromosome bands fused during later pachytene condensation.
