“…Mechanical damage ( Dorokhov et al, 2012 ) and the attack of pathogens ( von Dahl et al, 2006 ; Körner et al, 2009 ) increase the synthesis of tobacco PMEs, accelerate de-esterification processes and dramatically increase methanol emission ( Lionetti et al, 2012 ; Komarova et al, 2014b ; Dorokhov et al, 2015 ). Methanol is considered not only a by-product of PME activity but also a participant in cell signaling and an inducer of plant protection reactions ( Tran et al, 2018 ). Transgenic tobacco plants with overexpression of the PME genes from A. thaliana or Aspergillus niger dramatically increased methanol emission and resistance to plant sap sucking pests Myzus persicae (aphid) and Bemisia tabaci (whitefly) ( Dixit et al, 2013 ).…”

Until recently, plant-emitted methanol was considered a biochemical by-product, but studies in the last decade have revealed its role as a signal molecule in plant-plant and plant-animal communication. Moreover, methanol participates in metabolic biochemical processes during growth and development. The purpose of this review is to determine the impact of methanol on the growth and immunity of plants. Plants generate methanol in the reaction of the demethylation of macromolecules including DNA and proteins, but the main source of plant-derived methanol is cell wall pectins, which are demethylesterified by pectin methylesterases (PMEs). Methanol emissions increase in response to mechanical wounding or other stresses due to damage of the cell wall, which is the main source of methanol production. Gaseous methanol from the wounded plant induces defense reactions in intact leaves of the same and neighboring plants, activating so-called methanol-inducible genes (MIGs) that regulate plant resistance to biotic and abiotic factors. Since PMEs are the key enzymes in methanol production, their expression increases in response to wounding, but after elimination of the stress factor effects, the plant cell should return to the original state. The amount of functional PMEs in the cell is strictly regulated at both the gene and protein levels. There is negative feedback between one of the MIGs, aldose epimerase-like protein, and PME gene transcription; moreover, the enzymatic activity of PMEs is modulated and controlled by PME inhibitors (PMEIs), which are also induced in response to pathogenic attack.

“…We have seen aspects of that in Peter's wider-reaching contributions to plant 'intelligence' and plant-environment interactions, extending as far as the moon and its influence on the biology of Earth-bound plants. It therefore seems appropriate that the SIAB has a contribution by Tran et al [180] investigating the mode of action of methanol and information transfer'.…”

“…As important at this process is, the molecular mechanism(s) underlying this methanolic defence-priming are not well understood. Accordingly, Tran et al [180] investigated the effects of methanol on Arabidopsis and tobacco BY2 cells. They found that methanol induces variations in cytoplasmic concentrations of calcium that could then interact with reactive oxygen species and a signalling pathway that results in already wellcharacterised plant response to pathogen attack such as plasma membrane depolarization and synthesis of ethylene.…”

Dr Peter Barlow, who died in 2017, was one of the most respected botanists and biologists of the latter half of the 20th Century. His interests covered a wide range of plant biological topics, e.g. root growth and development, plant cytoskeleton, effects of gravity, plant intelligence, pattern formation, and evolution of eukaryotic cells. Here we consider Peter’s numerous contributions to the: elucidation of plant patterns; understanding of root biology; role of the plant cytoskeleton in growth and development; influence of the Moon on terrestrial vegetation; Cell Body concept; and plant neurobiology. In so doing we attempt not only to provide an overview of Peter’s important work in many areas of plant biology, but also to place that work in the context of recent advances in plant and biological sciences.

“…Moreover, AtPME17 could assist in the release of additional cell wall‐derived damage‐associated molecular patterns, like the β‐1,4 cellodextrins or the pentose‐based cell wall oligosaccharides, important in Arabidopsis immunity (Mélida et al, 2020; Souza et al, 2017). Recently, methanol was demonstrated to induce cytosolic calcium variations, membrane depolarization, and ET production in A. thaliana (Tran et al, 2018). AtPME17 could also trigger PDF1.2 through methanol release.…”

Plant pathogens negatively affect agricultural production by reducing the plant yield and worsening the nutritional and qualitative characteristics of the harvest. To limit the damage caused by pathogen infection, crops are treated with large doses of pesticides, which cause soil and groundwater pollution. The use of crop varieties genetically resistant to necrotrophs represents a more sustainable solution but is limited by the scarcity of resistance genes to be integrated into crops. For this reason, the identification of new

Methanol induces cytosolic calcium variations, membrane depolarization and ethylene production in arabidopsis and tobacco

Abstract: Methanol is not only a by-product of PME activities, and our data suggest that [Ca2+]cyt variations could participate in signalling processes induced by methanol upstream of plant defence responses.
