Abstract

Most horticultural products are highly perishable, which seriously affects their shelf life and postharvest quality. Thus, there is an urgent demand for innovative preservation techniques to reduce postharvest losses. In recent years, small-molecule gases small-molecule gases have been found to be involved in regulating the postharvest quality of horticultural products. These compounds include nitric oxide (NO), ethylene (ETH), hydrogen (H₂), carbon monoxide (CO), hydrogen sulfide (H₂S), carbon dioxide (CO₂), and hydrogen peroxide (H₂O₂). This review discusses the functions and mechanisms of small signaling molecules involved in the postharvest quality of horticultural products. In addition, the crosstalk between these compounds in the preservation of horticultural products has been emphasized. Small-molecule gases improve the postharvest quality of horticultural products by modulating the levels of reactive oxygen species (ROS), regulating ETH biosynthesis, modulating antioxidant systems, increasing secondary metabolites, regulating the expression of senescence-related genes, participating in signaling, and activating resistance pathways to mitigate cold damage and enhance disease resistance. Research has focused on the role of synergies between gas molecules in the postharvest stages of horticultural products. Thus, the role of small-molecule gases in improving the postharvest quality of horticultural products is a potential direction for future research.

保持园艺产品采后品质的小分子气体研究进展

大多数园艺产品都是高度易腐的，这严重影响了它们的保质期和采后质量。因此，迫切需要创新的保存技术来减少采后损失。近年来，小分子气体被发现参与调控园艺产品采后质量。这些化合物包括一氧化氮（NO）、乙烯（ETH）、氢（H2）、一氧化碳（CO）、硫化氢（H2S）、二氧化碳（CO2）和过氧化氢（H2O2）。本文就小信号分子在园艺产品采后品质中的作用及机制作一综述。此外，还强调了这些化合物之间的串扰在园艺产品保存中的作用。小分子气体通过调节活性氧（ROS）水平、调节ETH生物合成、调节抗氧化系统、增加次生代谢物、调节衰老相关基因的表达、参与信号传导和激活抗性途径来改善园艺产品采后品质，从而减轻冷损伤，增强抗病性。研究的重点是气体分子在园艺产品收获后阶段的协同作用。因此，小分子气体在提高园艺产品采后品质中的作用是未来研究的一个潜在方向。

期刊介绍： Physiologia Plantarum is an international journal committed to publishing the best full-length original research papers that advance our understanding of primary mechanisms of plant development, growth and productivity as well as plant interactions with the biotic and abiotic environment. All organisational levels of experimental plant biology – from molecular and cell biology, biochemistry and biophysics to ecophysiology and global change biology – fall within the scope of the journal. The content is distributed between 5 main subject areas supervised by Subject Editors specialised in the respective domain: (1) biochemistry and metabolism, (2) ecophysiology, stress and adaptation, (3) uptake, transport and assimilation, (4) development, growth and differentiation, (5) photobiology and photosynthesis.
