Other claims from this paper (6)
- Observation In transgenic A. thaliana, the lat52 promoter activated in late uninucleate microspores before mitosis.
- Mechanism The lat52 promoter activation in A. thaliana was not strictly dependent on passage through microspore mitosis.
- Observation The lat52 promoter showed a similar cumulative activity pattern during vegetative cell maturation in both species.
- Association The similar promoter activity pattern correlated with similar gus transcript accumulation.
- Association The similar promoter activity pattern correlated with similar spore protein content.
- Observation In A. thaliana pollen, lat52 promoter activity localized specifically to the vegetative cell.
