Isoprene is a highly reactive volatile organic compound that significantly affects atmospheric oxidant capacity, regional air quality, and climate change. Moso bamboo (Phyllostachys edulis), a species widely distributed in tropical and subtropical regions, particularly in China, is a strong isoprene emitter with great potential for carbon sequestra...
Isoprene emission has been considered to protect plants from heat stress, but there is limited information of how sustained heat spells which can be particularly severe under drought alters the plant capacity to produce isoprene. Under combined long-term stresses isoprene emission could contribute to maintenance of the precursor pool for rapid synt...
Volatile emissions from urban parks and forests can significantly contribute to local and regional air quality due to biogenic volatile organic compound (BVOC) emissions from vegetation, but the source strength of BVOC of urban habitats is difficult to assess due to a complex mixture of ornamental species with widely varying leaf and whole plant ch...
Leaf age alters the balance between the use of end-product of plastidic isoprenoid synthesis pathway, dimethylallyl diphosphate (DMADP), in prenyltransferase reactions leading to synthesis of pigments of photosynthetic machinery and in isoprene synthesis, but the implications of such changes on environmental responses of isoprene emission have not...
Plant isoprene emissions have been modelled assuming independent controls by light, temperature and atmospheric [CO2]. However, the isoprene emission rate is ultimately controlled by the pool size of its immediate substrate, dimethylallyl
diphosphate (DMADP), and isoprene synthase activity, implying that the environmental controls might interact. I...
The lack of a mechanistic basis has hampered modelling isoprene emission responses to environmental drivers, in particular the simulation of isoprene emissions under different CO2 concentrations. Here, we advance previous semi-mechanistic model formulations by introducing a model that explicitly links electron availability for other purpose than ca...
We present a unifying model for isoprene emission by photosynthesizing leaves based on the hypothesis that isoprene biosynthesis depends on a balance between the supply of photosynthetic reducing power and the demands of carbon fixation.
We compared the predictions from our model, as well as from two other widely used models, with measurements of i...
Isoprene emissions importantly protect plants from heat stress, but the emissions become inhibited by instantaneous increase
of [CO2], and it is currently unclear how isoprene-emitting plants cope with future more frequent and severe heat episodes under
high [CO2]. Hybrid aspen (Populus tremula x Populus tremuloides) saplings grown under ambient [C...
Effects of elevated atmospheric [ CO 2 ] on plant isoprene emissions are controversial. Relying on leaf‐scale measurements, most models simulating isoprene emissions in future higher [ CO 2 ] atmospheres suggest reduced emission fluxes. However, combined effects of elevated [ CO 2 ] on leaf area growth, net assimilation and isoprene emission rates...

... When there is severe long-term light stress, photosynthetic organs are damaged, and ISO synthesis is more sensitive and complicated. Sun et al. (2020) conducted experiments using hybrid poplars and showed that other BVOCs, such as MTs, have a greater contribution to enhancing plant resistance under severe stress, and the role of ISO is greatly reduced. ...

... Previous studies indicated that it is possible to mitigate emissions of air pollutants in urban areas by optimizing tree species selection (Ren et al., 2017). However, in-situ observations of ISOP emissions from urban tree species are still very limited, especially in over-expanding megacities with many local species (Curtis et al., 2014;Ghirardo et al., 2016;Jing et al., 2020;Yuan et al., 2020). This is particularly important in a country like China where cities are distributed across very large areas, and urban vegetation varies greatly from city to city (Bao et al., 2023). ...
... Generally, various environmental conditions affect plant growth, such as light, soil water content, temperature, and soil nutrients [23]. Among these, light is the most important environmental factor affecting plant establishment, growth, and survival [24,25]. Taiz and Zeiger [26] also supported the importance of light in plant growth as light energy was used to produce ATP and NADPH in the light reactions of photosynthesis. ...

... Therefore, in addition to focusing on the potential negative impact of isoprene emissions on the environment, the net photosynthetic productivity of forests should be considered. Isoprene is primarily produced from newly absorbed photosynthates via the 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway under light (Niinemets and Sun, 2015;Pokhilko et al., 2015). Under normal conditions, the majority (70-90%) of isoprene formations is directly from photosynthesis, which provides carbon skeletons, reducing power (NADPH), and energy (ATP) for isoprene biosynthesis (Delwiche and Sharkey, 1993;Karl et al., 2002;Affek and Yakir, 2003;Loreto et al., 2004). ...
... Light-dependent BVOC emissions are represented as a fraction of the electron transport rate as proposed by Niinemets et al. (1999); a theoretical approach that is based not on the transport rate as such but on the excess of electrons (JJv model) has been suggested by Morfopoulos et al. (2014) and elaborated by Grote et al. (2014). Emissions that are assumed to origin from storages and therefore are temperature-dependent only, are simulated with an exponential relation suggested by Guenther et al. (1993). ...

... However, regulation of enzyme activities under the combined effect of increased temperature and CO 2 requires further investigation. Previous studies demonstrated that isoprene emission is correlated with the in vivo pool size of DMADP (29,46,47). In fact, Niinemets et al. (31) showed that DMADP levels decrease at high CO 2 in some species, resulting in reduction of isoprene emission. ...

... More recent laboratory studies provide evidence that certain plant species emit more isoprene in high CO 2 environments (e.g. Sun et al., 2013), indicating that there are still some gaps in the understanding of biochemical regulation of BVOC leaf emissions incorporated in such models. Grote and Niinemets (2007) compares the two model categories and argues that, in non-stressful conditions, empirical and process-based emission models predict BVOC emission dependencies on light and temperature in a similar way. ...

... Therefore, our results suggest that high CO 2 signal inhibits the activity of the HDR such that the conversion of HMBDP to DMADP is impeded, resulting in lower isoprene emission at high CO 2 (Fig. 3E). While CO 2 responsiveness of isoprene emission varies among the species, we observed a 42% decrease in isoprene emission from poplar leaves at elevated CO 2 (Fig. 1B), which corresponded to previous findings (31)(32)(33). Our data also indicate that CO 2mediated suppression of isoprene emission is independent of stomatal conductance (SI Appendix, Fig. S1B), consistent with the findings of Jones and Rasmussen (34). ...
