Other claims from this paper (9)
- Association Polyamine amounts across pea lines correlated with internode elongation.
- Association Young internodes had high polyamine concentrations that decreased with expansion.
- Intervention effect Alpha-difluoromethylornithine inhibited polyamine accumulation and internode elongation in tall and GA-stimulated nana peas.
- Intervention effect Alpha-difluoromethylarginine inhibited polyamine accumulation and internode elongation in tall and GA-stimulated nana peas.
- Intervention effect Agmatine restored growth and endogenous polyamine content to variable degrees.
- Intervention effect Putrescine restored growth and endogenous polyamine content to variable degrees.
- Intervention effect Exogenous polyamines did not promote growth unless intracellular amines were partly depleted.
- Mechanism Authors infer polyamines may support cell proliferation rather than cell elongation.
- Mechanism Authors infer polyamines mediate only part of GA-induced internode growth, affecting cell division rather than elongation.
