Other claims from this paper (8)
- Observation Heterocyst DNA content strongly increased in the basal leaf cavities.
- Observation DAPI brightness of heterocysts was quite uniform along the apex-to-basal groups.
- Observation DAPI brightness of vegetative cells increased from the apex to the basal groups.
- Observation In vegetative cells from the apex to the median group, DAPI brightness was 60-85% of AO brightness.
- Observation In heterocysts of the same apex-to-median groups, DAPI brightness was 40-50% of AO brightness.
- Observation In the basal group, DAPI brightness was comparable to the previous group in both heterocysts and vegetative cells.
- Observation In the basal group, chromomycin brightness increased strongly in heterocysts.
- Observation The authors conclude that the heterocyst changes its DNA content and composition in the basal leaf cavities, suggesting its lifetime is not completely over.
