Abstract
Storage and maintenance of horticultural products in optimal conditions for a reasonable period, once they have been harvested is a technological challenge. Diverse methods are generally used, i.e., low temperature but, in many cases, it may provoke undesirable collateral effects such as softening or promoting pathogens infections, thus causing their deterioration. Nitric oxide (·NO) and hydrogen sulfide (H2S) are compounds generated endogenously by plants with signaling properties that mediate fruit development and ripening. Additionally, when these molecules are applied exogenously, they can provide benefits such as maintaining the quality of horticultural products and even prolonging their shelf-life once they are stored. This review provides a broad perspective of ·NO and H2S metabolism in plant cells and, in addition, different plant models are described of how the exogenous application of either NO or H2S to horticultural products preserves nutritional quality during postharvest storage.
