Postharvest high-CO2 treatments on the quality of soft fruit berries: An integrated transcriptomic, proteomic, and metabolomic approach

Soft fruits are appreciated for their taste qualities and for being a source of health-promoting compounds. However, their postharvest is affected by their high respiratory rates and susceptibility to fungal decay. Our aim here is to provide a perspective on the application of short-term high-CO2 treatments at a low temperature to maintain the postharvest quality of soft fruits. This work also suggests using a multi-omics approach to better understand the role of the cell wall and phenolic compounds in maintaining quality. Finally, the contribution of high-throughput transcriptomic technologies to understand the mechanisms modulated by the short-term gaseous treatments is also highlighted.This work was supported by CICYT Project PID2020-113965RB-I00/AEI/10.13039/501100011033.Peer reviewe
