New chapter published – Environmental Impacts on Plant Volatile Emission

Text by Lauri Laanisto

A book chapter for a change. Review of all the volatile organic compounds that plants emit when they experience 1) high temperatures; 2) low temperatures; 3) drought; 4) flooding. Thus, this review covers most of the main factors of abiotic stress, more or less following the same topical build-up than couple of macroecological and macrophysiological papers from past decade, like Niinemets & Valladares 2006 EcolMonogr (link to full text) and Laanisto & Niinemets 2015 GEB (link to full text) (link to blog post). Except it does not cover shading. But not to worry. We´ll also have a fresh review paper (Grubb review nr 3) out about shade and how it affects plants (link to full text) – I´ll be blogging about that one in the coming days. Anyways – it seems the next step would be to put all this knowledge together, from BVOCs to species biogeography and phylogenetic background. Simple, ehh…

Abstract:

Plants in their natural environment are often exposed to a variety of environmental stresses. This chapter emphasises the importance of distinguishing among stress effects on constitutive and stress-induced volatile emissions and, within constitutive emissions, among stress effects on emissions from specialised storage compartments (storage emissions) and de novo emissions. Among constitutive emissions, de novo emissions are typically more sensitive to stress than storage emissions. Depending on stress severity, the emission response is either physiological or the emission response is controlled at the gene expression level. This chapter analyses the impacts of heat, cold, drought and waterlogging stresses on constitutive and induced emissions, highlights similarities and differences of various stresses on volatile release and outlines the gaps in knowledge. We argue that for a fully mechanistic understanding of environmental impacts on plant chemical communication channels, more work is needed to obtain quantitative stress dose versus emission responses for different stresses in species of differing stress tolerance.
