Summary: This study identified different isoforms of NI in potato cultivars, indicating their varied roles in sucrose degradation during cold storage. The findings suggest the significant contribution of NI in regulating reducing sugars and cold-induced sweetening in potatoes, highlighting the need for further research to determine the in vivo function of NI in cold-stored potato tubers.

Summary: Invertase inhibitors, classified as cell wall/apoplastic and vacuolar, play a crucial role in the cold-induced sweetening (CIS) process of potato tubers. Gene mapping studies have shown that the invertase inhibitor genes are located on chromosome twelve in potatoes, providing insights on their divergence into cell wall and vacuole forms.

Summary: Senescent sweetening in potato tubers leads to the accumulation of reducing sugars during long-term storage, causing issues in processing. Contrary to previous studies, our analysis found no correlation between oxidative stress and reducing sugar accumulation. Transcriptional profiling revealed changes in carbohydrate metabolism at the onset of sweetening, potentially linked to reduced capacity of plastids to import glucose-6-phosphate.

Summary: To cope with cold stress, plants develop antioxidation strategies and osmoprotection by sugars. In potato tubers, exposure to cold stress induces starch degradation and sucrose synthesis. Vacuolar acid invertase (VInv) activity is a significant part of the cold-induced sweetening (CIS) response, increasing osmoprotection.

Summary: In this study, the expression analysis of genes associated with cold-induced sweetening in potato tubers was performed, including vacuolar invertase, sucrose synthase, and invertase inhibitor. The accumulation of sugars at low temperatures was observed in all three potato varieties, with the highest accumulation of reducing sugars at 4 degrees C. The expression pattern of genes associated with cold-induced sweetening differed depending on the potato variety and storage duration. The involvement of these genes in the process of cold-induced sweetening was discussed.

Summary: The use of a sprout suppressor is crucial for extending the storage period of potatoes. A comparison between 1,4-dimethylnaphthalene (1,4-DMN) and chlorpropham (CIPC) showed that 1,4-DMN is an effective alternative to CIPC in controlling sprouting and maintaining the quality of potatoes during cold storage. Both inhibitors led to improved starch content, reduced reducing sugar content, and preserved the recommended quality for industrial processing. Furthermore, French fries made from potatoes treated with 1,4-DMN or CIPC showed less browning after frying, indicating the contribution of 1,4-DMN to the quality maintenance of French fries.

Summary: In this study, it was found that mechanical wounding of potato tubers significantly upregulated the expression levels of starch enzyme-related genes, decreased starch content, and increased the contents of sucrose, glucose, and fructose. Wounding also led to changes in the proportion and size distribution of starch granules in potato tubers.

Summary: The knockdown of the VInv gene in potato using CRISPR/Cas9 resulted in a decrease in post-harvest cold-storage sugars formation and sweetening in potatoes. The transformation efficiency of potatoes was 11.7%, and the overall editing efficacy was 25.6%. The edited potato plants showed a significant reduction in the mRNA expression of the VInv gene and a fivefold reduction in the percentage of reducing sugars in tubers after cold storage. The best lines for cold storage analysis were B4 and T12.

Summary: Drought stress is a significant problem for potato production, especially with climate change and temperature peaks along with drought periods. This study aimed to analyze eight genes and determine their suitability for detecting early drought stress in potato. Six potato genotypes were examined for plant growth and physiological parameters after seven and 14 days of stress. Changes in gene expression were observed after seven days of stress for three genes: INH1, POD, and SBT1.7. The INH1 gene showed consistent upregulation in all genotypes and may be a suitable candidate for detecting drought stress in potato.

Summary: Postharvest sweetening can improve the eating quality of sweetpotato, particularly of immature sweetpotato. The sucrose content increased at all temperatures, while glucose and fructose mainly increased at 4 degrees C. The study suggests that IbVIN1 could be a candidate gene in cultivating sweetpotato varieties high in sweetness.

Summary: Potatoes are highly susceptible to elevated temperatures, which can lead to reduced photosynthetic capacity and membrane stability. Short and prolonged heat stress resulted in significant changes in gene expression and metabolite levels related to photosynthesis, heat response, and amino acid biosynthesis, suggesting their potential role in heat tolerance of potatoes. Additionally, heat-induced gene expression in Arabidopsis thaliana and potato leaves overlapped, and certain heat-induced genes in Nicotiana benthamiana increased heat tolerance. This study provides new insights into the molecular mechanisms underlying the potato's response to heat stress.

Summary: The study reveals the positive role of Ca2+ ATPase in litchi energy metabolism and senescence. Higher expression of LcACAs is associated with better storability in litchi cultivars. Additionally, LcACA2 is identified as a target of LcmiR482e and ATP application can downregulate the expression of LcmiR482e, contributing to delayed senescence in litchi.

Summary: This study aimed to compare the discrimination ability and detection limit of visible and short-wave near-infrared hyperspectral imaging features and spectral information on early implicit bruised pears. Physical characteristics were more sensitive than chemical parameters for bruised pears during postharvest storage. The changes in spectral variations at specific wavelengths could explain the bruising changes in pears. Discrimination models based on selected spectral variables could effectively identify bruised pear areas, and the combination of imaging features and spectral variables achieved higher discrimination rates.

Summary: This study evaluated a large set of blueberry cultivars to understand the relationship between mechanical texture and appearance characteristics at harvest and after storage, and tested multiple statistical models to predict shelf-life. The results showed that fruit characteristics measured at harvest or two weeks post-harvest can predict weight loss, texture change, and fruit wrinkling. These findings provide empirical data that blueberry breeders can use to select cultivars with extended shelf-life.

Summary: This study found that H2S treatment can delay the senescence process of postharvest pakchoi by regulating antioxidant system, endogenous H2S and NO metabolism. H2S increased the activities of antioxidant enzymes by up-regulating the expression of enzyme genes, reducing the accumulation of harmful substances. Furthermore, H2S increased the content of cysteine and nitrate in pakchoi by regulating the expression of related genes and enzyme activities, thus slowing down the senescence of pakchoi.
