Emission and Function of Volatile Organic Compounds in Response to Abiotic Stress

Biosynthesis of essential oils in aromatic plants: A review

“…Such plants also have better tolerance against many reactive oxygen species and ozone as compared to nonisoprene-emitting plants. [227][228][229][230][231] Hanson et al [232] hypothesized that emission of isoprene might have been a vital step in the evolution of terrestrial plants. As plant ancestors started to grow in the air, the temperature variation for plant was high due to low heat capacity of air as compared to water.…”

“…[228,233] After frequent episodes of high temperature, the leaves with isoprene or monoterpene emission maintain high rates of photosynthesis as compared to nonemitting leaves. [228,229,233] The motivating thought behind this study is that these terpenes provide quick means of thermal protection before more complex thermo-protecting molecules are synthesized by plants. [223] Transpiration is a general process to reduce the leaf temperature that is controlled by relative humidity of air.…”

“…Thus, the A c c e p t e d M a n u s c r i p t 38 isoprene (a thermo-tolerant) emission had a major role in land migration of Bryophyta, the first land plant. [228,232] 1) Monoterpenes (C 10 ) also provide this type of thermo-tolerance in aromatic plants. [228,233] After frequent episodes of high temperature, the leaves with isoprene or monoterpene emission maintain high rates of photosynthesis as compared to nonemitting leaves.…”

“…[226][227][228] The function of isoprene in thermo-tolerance of plants has been widely studied in several experiments. Plants that secrete isoprene have better ability to tolerate short high-temperature periods of sunlight.…”
