Postharvest Treatment of Hydrogen Sulfide Delays the Softening of Chilean Strawberry Fruit by Downregulating the Expression of Key Genes Involved in Pectin Catabolism.

Hydrogen sulfide (HS) plays several physiological roles in plants. Despite the evidence, the role of HS on cell wall disassembly and its implications on fleshy fruit firmness remains unknown. In this work, the effect of HS treatment on the shelf-life, cell wall polymers and cell wall modifying-related gene expression of Chilean strawberry () fruit was tested during postharvest storage.
