      abstract     = {The volatile hemiterpene isoprene is emitted from plants
                      and can affect atmospheric chemistry. Although recent
                      studies indicate that isoprene can enhance thermotolerance
                      or quench oxidative stress, the underlying physiological
                      mechanisms are largely unknown. In this work, Arabidopsis
                      (Arabidopsis thaliana), a natural nonemitter of isoprene and
                      the model plant for functional plant analyses, has been
                      constitutively transformed with the isoprene synthase gene
                      (PcISPS) from Grey poplar (Populus x canescens).
                      Overexpression of poplar ISPS in Arabidopsis resulted in
                      isoprene-emitting rosettes that showed transiently enhanced
                      growth rates compared to the wild type under moderate
                      thermal stress. The findings that highest growth rates,
                      higher dimethylallyl diphosphate levels, and enzyme activity
                      were detected in young plants during their vegetative growth
                      phase indicate that enhanced growth of transgenic plants
                      under moderate thermal stress is due to introduced PcISPS.
                      Dynamic gas-exchange studies applying transient cycles of
                      heat stress to the wild type demonstrate clearly that the
                      prime physiological role of isoprene formation in
                      Arabidopsis is not to protect net assimilation from damage
                      against thermal stress, but may instead be to retain the
                      growth potential or coordinated vegetative development of
                      the plant. Hence, this study demonstrates the enormous
                      potential but also the pitfalls of transgenic Arabidopsis
                      (or other nonnatural isoprenoid emitters) in studying
                      isoprene biosynthesis and its biological function(s).},
