Temporal regulation of terpene synthase gene expression in <i>Eucalyptus globulus</i> leaves upon ozone and wounding stresses: relationships with stomatal ozone uptake and emission responses.

ABSTRACT: Ozone and wounding are key abiotic factors but, their interactive effects on temporal changes in terpene synthase gene expression and emission responses are poorly understood. Here, we applied combined acute ozone and wounding stresses to the constitutive isoprenoid-emitter Eucalyptus globulus and studied how isoprene, 1,8-cineole, and isoledene synthase genes were regulated, and how the gene expression was associated with temporal changes in photosynthetic characteristics, product emission rates, and stomatal ozone uptake through recovery phase. Photosynthetic characteristics and emission rate of isoprene, 1,8-cineole, and isoledene were synergistically altered, while three TPS gene expressions were antagonistically altered by combined stress applications.
