Other claims from this paper (13)
- Mechanism Bioactive GAs feedback regulate the GA 20-oxidase genes.
- Intervention effect Overexpressing any GA 20-oxidase cDNA elongated seedling hypocotyls.
- Intervention effect Overexpression caused earlier flowering under long and short days.
- Intervention effect Overexpressing plants were 25% taller at maturity.
- Intervention effect Overexpression raised rosette GA4 levels two- to threefold.
- Intervention effect AtGA20ox1 antisense plants had short hypocotyls and reduced stem elongation.
- Intervention effect AtGA20ox1 antisense reduced GA4 in rosettes and shoot tips.
- Intervention effect AtGA20ox1 antisense delayed flowering in short days.
- Intervention effect AtGA20ox1 antisense reduced stem elongation more in short days.
- Intervention effect AtGA20ox2 antisense had no apparent effects in long days.
- Intervention effect One AtGA20ox2 antisense line had 20% less stem growth in short days.
- Intervention effect AtGA20ox3 antisense generally had no visible effect.
- Intervention effect One AtGA20ox3 antisense line had short hypocotyls.
