摘要：

Previous studies have shown that plant hemoglobin (Hb) mRNA is expressed in barley (Hordeum vulgare L.) aleurone layers during hypoxia. We have examined the effect of a number of respiratory inhibitors on barley aleurone layers to determine the factors that influence Hb gene expression. Respiratory inhibitors that reduce O-2 consumption, such as CO, cyanide, and antimycin A, strongly enhanced Hb mRNA levels. Treatment with the oxidative phosphorylation uncoupler 2,4-dinitrophenol markedly increased O-2 consumption and had a similar positive effect on Hb gene expression. Hb transcript levels were also stimulated by the ATP synthase inhibitor oligomycin. The results suggest that the expression of Hb is not directly influenced by O-2 usage or availability but is influenced by the availability of ATP in the tissue.
