Other claims from this paper (7)
- Intervention effect Floral development of the gib-1 mutant is not completed unless the mutant is treated with gibberellin.
- Intervention effect Treatment with other plant growth regulators does not induce normal flower development in gib-1.
- Observation Development of gib-1 flower buds, as measured by progress toward anthesis, ceases at a bud length of 2.5 millimeters.
- Observation Bud size of gib-1 flower buds continues to increase after development ceases.
- Intervention effect Buds of 2.5 to 3.7 millimeters are developmentally arrested but still develop normally after treatment with gibberellic acid.
- Observation Anthers of developmentally arrested buds contain pollen mother cells in the G1 phase of premeiotic interphase.
- Intervention effect Gibberellic acid treatment of arrested buds makes prophase I of meiosis and meiosis-related changes in tapetum development observable within 66 hours.
