Production of Isoprene by Leaf Tissue 1

PMCID: PMC541751  PMID: 16659231

Abstract

Isoprene production by Hamamelis virginiana L. and Quercus borealis Michx. leaves was studied. When ambient CO2 concentrations were maintained with bicarbonate buffers, the rate of isoprene production at 125 microliters per liter of CO2 was approximately four times that at 250 microliters per liter of CO2. Isoprene production was drastically inhibited by 97% O2. Dichlorodimethylphenylurea (0.1 mm), NaHSO3 (10 mm), and α-hydroxy-2-pyridinemethanesulfonic acid (10 mm) inhibited isoprene production but increased the compensation point of the tissue. Isonicotinic acid hydrazide neither inhibited isoprene emission nor increased the compensation point of the tissue significantly. Inhibition of isoprene production does not seem to correlate with stomatal resistance. Isoprene was labeled by intermediates of the glycolate pathway, and similarities are noted between the biosynthesis of isoprene and that of β-carotene.
