Other claims from this paper (13)
- Observation IAA levels increased during fiber development.
- Association IAA levels were higher in long-fiber varieties.
- Intervention effect IAA promoted fiber elongation in a dose-dependent manner in ovule culture.
- Mechanism IAA activated BR biosynthesis.
- Intervention effect IAA partially rescued fiber elongation under brassinazole-induced BR deficiency.
- Intervention effect IAA partially rescued fiber elongation in pag1 mutants.
- Intervention effect BR supplementation partially alleviated fiber inhibition from impaired IAA transport.
- Intervention effect BR supplementation partially alleviated fiber inhibition from IAA deficiency.
- Mechanism Neither IAA nor BR fully compensated for absence of the other in fiber elongation.
- Intervention effect Hexokinase suppression by N-acetylglucosamine impaired fiber growth.
- Intervention effect Exogenous IAA rescued fiber growth impaired by glucose signaling inhibition.
- Intervention effect Exogenous BR rescued fiber growth impaired by glucose signaling inhibition.
- Mechanism Glucose was inferred to act upstream of IAA and BR in regulating cotton fiber elongation.
