| Resumo: | Crops of tropical and subtropical origin are cold-sensitive at every stage of the lifecycle, including postharvest cold storage. Chilling-induced damage leads to diverse symptoms which manifest as external alterations (surface pitting, discolouration), internal disorders (browning, water soaking) and/or impaired physiological processes (ripening and growth inhibition, wilting, altered flavour, decay). Plants have developed complex tolerance mechanisms to counteract or to minimize chilling injury (CI), including stress perception, signal transduction, transcriptional activation of stress-responsive target genes, and the synthesis of stress-related proteins and other molecules. The integration of molecular and omics-based approaches has provided new loci for marker-assisted breeding toward chilling tolerance. Thus, understanding the physiological, biochemical and molecular responses underlying these tolerance mechanisms, and the causal genes, is paramount to engineering strategies for enhanced tolerance to chilling stress. This Research Topic was launched to gather recent investigations in this field. Fourteen papers were finally compiled, which examined a wide range of edible and non-edible plant species, including climacteric and non-climacteric fruit species, herbs, and edible corms or seedlings belonging to different botanical families. They explored general mechanisms involved in plant cold tolerance and the suitability of exogenous treatments for alleviating CI-related disorders. |
