dc.description.abstract | Abstract | Hydrogen sulfide (H2S) plays several physiological roles in plants. Despite the evidence,
the role of H2S on cell wall disassembly and its implications on fleshy fruit firmness remains
unknown. In this work, the effect of H2S treatment on the shelf-life, cell wall polymers and cell
wall modifying-related gene expression of Chilean strawberry (Fragaria chiloensis) fruit was tested
during postharvest storage. The treatment with H2S prolonged the shelf-life of fruit by an effect of
optimal dose. Fruit treated with 0.2 mM H2S maintained significantly higher fruit firmness than
non-treated fruit, reducing its decay and tripling its shelf-life. Additionally, H2S treatment delays
pectin degradation throughout the storage period and significantly downregulated the expression of
genes encoding for pectinases, such as polygalacturonase, pectate lyase, and expansin. This evidence
suggests that H2S as a gasotransmitter prolongs the post-harvest shelf-life of the fruit and prevents
its fast softening rate by a downregulation of the expression of key pectinase genes, which leads to a
decreased pectin degradation. | es |
