Abstract
The existence of at least two saturable, high affinity binding sites for ethylene is demonstrated in rice seedlings. The sites differ markedly in their rates of association and dissociation. Suppression of endogenous ethylene biosynthesis leads to a significant enhancement of the [14C]ethylene binding observed. Norbornadiene inhibits ethylene binding and promotion of growth by ethylene. Carbon dioxide and hypoxia promote growth but neither affects ethylene binding.
