Fundamental aspects of postharvest heat treatments

Abstract

Heat treatments have been investigated for use in many aspects of postharvest storage. They have been developed for insect control, prevention of fungal development and prevention of postharvest storage disorders including chilling injury. The treatment times and temperature range vary widely, from days at 35 °C to 39 °C in hot air, to up to 63 °C for less than a minute in hot water. Much of the research has been performed to develop solutions to a particular problem, and less investigation has been conducted on the responses of the commodity to the treatment. However, since the turn of the century, a number of groups have been active in examining the molecular responses and changes that occur in commodities during and after the heat treatment. This review examines the changes at the level of transcriptome, proteome and metabolome that occur in response to the different heat treatments.

<p>A schematic model for temperature sensing in plants. Changes in temperature can alter membrane properties and activate a calcium channel. The inward flux of calcium that follows will activate signal transduction events and alter plant metabolism to achieve thermotolerance. Additional temperature-induced changes include alterations in protein stability and exposure of hydrophobic residues of proteins that may trigger ubiquitin in the cytosol and the ER, histone displacement which allows HSFs to bind to DNA, accumulation of ROS and alteration in cellular energy levels, and unfolding of RNA species that could affect miRNA. These pathways will also trigger different signal transduction events and lead to thermotolerance (adapted from Mittler
