Isoprene enhances leaf cytokinin metabolism and induces early senescence

, 2022
●Isoprene, a major biogenic volatile hydrocarbon of climate-relevance, indisputably mitigates abiotic stresses in emitting plants. However functional relevance of constitutive isoprene emission in unstressed plants remains contested.

New formation and fate of Isoprene SOA markers revealed by field data-constrained modeling

npj Climate and Atmospheric Science, 2023
Particulate 2-methyltetrols (2-MT) and 2-methylglyceric acid (2-MG) are typically used to indicate the abundance of isoprene-derived secondary organic aerosols (SOA). However, their formation and fate are not fully understood.

Glyphosate residues in soil alter herbivore‐induced plant volatiles and affect predatory insect behaviour

Plant Biology, EarlyView.
Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

Food Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...

Structure of Copolymers of Isobutylene and Isoprene

, 1944
By means of ozone degradation experiments it has been shown that the isoprene units in copolymers of isoprene and isobutylene unite in the 1,4 positions. This conclusion is based on negative evidence.

Effect of chemical degradation on fluxes of reactive compounds – a study with a stochastic Lagrangian transport model [PDF]

Atmospheric Chemistry and Physics, 2012
In the analyses of VOC fluxes measured above plant canopies, one usually assumes the flux above canopy to equal the exchange at the surface. Thus one assumes the chemical degradation to be much slower than the turbulent transport.
