“…The 0.1% concentration was chosen based on the Codex Alimentarius recommendation 16 and because this concentration had similar effect alleviating CI in 'Palmer' mangoes to 2.5%. 12 Mangoes were then transferred to a cold room at 1.0 ± 0.5 °C and 75 ± 3.5% RH for a period of 28 days. At 7 day intervals, fruit were transferred to ambient conditions (∼23 ± 2.0 °C and 75 ± 3.0% RH) to check for development of CI and assess quality parameters and oxidative metabolism.…”

“…Increased SOD activity in fruit treated with 0.1% sorbitol, especially under low temperature, may have contributed to increased H 2 O 2 accumulation and reduced MDA content in the epicarp, because the superoxide anion (O 2 − ) is the main ROS associated with membrane degradation. 12 In addition, SOD plays a fundamental role in H 2 O 2 biosynthesis by converting it to O 2 − . 42 In turn, CAT and APX eliminate toxic H 2 O 2 from the cell, with APX being dependent on AsA concentration.…”

“…14 Recently, we showed that glycerol, propylene glycol, and sorbitol could be used effectively to alleviate CI symptoms and activate oxidative metabolism in 'Palmer' mangoes stored at 8.0 °C for 28 days. 12 These compounds could thus be used to prepare mangoes for cold quarantine. Thus, the objective of this study was to investigate the effect of applying glycerol, propylene glycol, or sorbitol to 'Palmer' mangoes stored at 1 °C for 28 days as an alternative to ameliorate CI during quarantine cold treatment, and to investigate whether non-enzymatic and enzymatic antioxidant defense systems would be affected by the polyol treatments.…”

“…In addition to occurring naturally in fruit and vegetables, they are commonly added to various fresh and processed foods as sweeteners, humectants, and cryoprotectants 13 and are ‘generally recognized as safe’ (GRAS) by the US Food and Drug Administration (FDA) 14 . Recently, we showed that glycerol, propylene glycol, and sorbitol could be used effectively to alleviate CI symptoms and activate oxidative metabolism in ‘Palmer’ mangoes stored at 8.0 °C for 28 days 12 . These compounds could thus be used to prepare mangoes for cold quarantine.…”

BACKGROUND Treatment with low temperatures can be used to quarantine mangoes against fruit‐fly infestation. However, mangoes can develop chilling injury (CI) when stored at temperatures below 13 °C. We demonstrated that the immersion in polyol solutions can alleviate CI symptoms in ‘Palmer’ mangoes stored at 8 °C. These suggest that polyols can be used to reduce CI in mangoes during quarantine at low temperatures. Thus, we investigated the efficacy of applying 0.1% (v/v) glycerol, propylene glycol, or sorbitol to ‘Palmer’ mangoes subjected to cold treatment (1.0 °C) for 28 days. Mangoes were then ripened at 23 °C for 7 days. RESULTS Among these polyols, sorbitol was the most effective in alleviating CI for up to 14 days of cold treatment. Mangoes treated with sorbitol showed lower levels of malondialdehyde (MDA) and hydrogen peroxide (H2O2), and reduced polyphenol oxidase (PPO) activity. These fruit also had elevated levels of ascorbate (AsA), especially in the epicarp, and increased superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) activity. CONCLUSION Sorbitol can reduce the CI, but to an unsatisfying level, and it should be combined with other treatments storage at low temperature. © 2022 Society of Chemical Industry.

Climate change seriously impacts global agriculture, with rising temperatures directly affecting the yield. Vegetables are an essential part of daily human consumption and thus have importance among all agricultural crops. The human population is increasing daily, so there is a need for alternative ways which can be helpful in maximizing the harvestable yield of vegetables. The increase in temperature directly affects the plants’ biochemical and molecular processes; having a significant impact on quality and yield. Breeding for climate-resilient crops with good yields takes a long time and lots of breeding efforts. However, with the advent of new omics technologies, such as genomics, transcriptomics, proteomics, and metabolomics, the efficiency and efficacy of unearthing information on pathways associated with high-temperature stress resilience has improved in many of the vegetable crops. Besides omics, the use of genomics-assisted breeding and new breeding approaches such as gene editing and speed breeding allow creation of modern vegetable cultivars that are more resilient to high temperatures. Collectively, these approaches will shorten the time to create and release novel vegetable varieties to meet growing demands for productivity and quality. This review discusses the effects of heat stress on vegetables and highlights recent research with a focus on how omics and genome editing can produce temperature-resilient vegetables more efficiently and faster.
