Other claims from this paper (13)
- Observation Unstable anthocyanin pigmentation was independently found six times.
- Observation All six unstable stocks traced to a mutable C2 allele.
- Observation Reversion produced pigment streaks and sectors in otherwise white petals and seeds.
- Observation Reversion could occur at different development times and produce periclinal chimeras.
- Observation c2‐m4 arose during tissue culture, unlike the other mutables found in populations.
- Observation m4 was very stable in plants and rarely made sectored flowers.
- Observation m4 was unstable in vitro, with about 23% revertant regenerated plants.
- Observation Most m4 reversion happened early, producing fully pigmented in vitro plants and large in planta sectors.
- Observation m5 and m6 were phenotypically and genetically similar.
- Observation m5 and m6 flowers were purple with white streaks, indicating dominant-to-recessive mutation.
- Observation White progeny of m5 and m6 were stable, with no observed white-to-purple reversion.
- Mechanism Absolute stability of m5 white derivatives favored a deficiency model.
- Mechanism Recurring mutations in mutable populations were speculated to result from transposable-element movement.
