Application

Application Comment Organism
environmental protection isoprene emission patterns in transgenic tobacco plants are remarkably similar to naturally emitting plants under a wide variety of conditions. Emissions correlate with photosynthetic rates in developing and mature leaves, and with the amount of isoprene synthase protein in mature leaves. Isoprene synthase protein levels do not change under short-term increase in heat/light, despite an increase in emissions under these conditions. A robust circadian pattern can be observed in emissions from long-day plants. Substrate supply and changes in enzyme kinetics rather than changes in isoprene synthase levels or post-translational regulation of activity seem to be the primary controls on isoprene emission in mature transgenic tobacco leaves Populus alba
