“…To alleviate the problem, research has been focused on decreasing the content of total reducing sugars in potato tubers as the most effective method to decrease acrylamide content in fried potatoes (Muttucumaru et al 2008). CIS has been widely studied in potato tubers (Foukaraki et al 2016;Mehdi et al 2013;Wiberley-Bradford et al 2016), and it has been reported that CIS occurs due to an imbalance between the metabolism of starch and sugar (Ezekiel et al 2010). The degradation pathway from starch to hexoses is complex, and several enzymes are involved in this progress, including sucrose synthase (SuSy), sucrose phosphate synthase (SPS), ADP-glucose pyrophosphorylase small subunit (AGPase), granulebound starch synthase (GBSS) (Wiberley-Bradford et al 2014).…”

The storage of potato tuber (Solanum tuberosum L.) at low temperatures minimizes sprouting and disease but can cause cold-induced sweetening (CIS), which leads to the production of the cancerogenic substance acrylamide during the frying processing. The aim of this research was to investigate the effects of UV-C treatment on CIS in cold stored potato tuber. 'Atlantic' potatoes were treated with UV-C for an hour and then stored at 4°C up to 28 days. The UV-C treatment significantly prevented the increase of malondialdehyde content (an indicator of the prevention of oxidative injury) in potato cells during storage. The accumulation of reducing sugars, particularly fructose and glucose, was significantly reduced by UV-C treatment possibly due to the regulation of the gene cascade, sucrose phosphate synthase, invertase inhibitor 1/3, and invertase 1 in potato tuber, which were observed to be differently expressed between treated and untreated potatoes during low temperature storage. In summary, UV-C treatment prevented the existence of oxidative injury in potato cells, thus, lowered the amount of reducing sugar accumulation during low temperature storage of potato tubers.

“…At two sampling times when blemishes consistent with senescent sweetening were apparent in many chips, 41 and 43 WAH, tissue samples from a position halfway between the apical and basal ends of the tubers were collected as previously described for more detailed analysis. One tissue sample from each tuber was processed for sucrose, glucose, and fructose quantification by high‐performance liquid chromatography as previously described .…”

“…Vacuolar invertase activity determines the hexose to sucrose ratio in potato tubers, with higher activity corresponding to higher ratios of hexose to sucrose . Reduction of VInv expression through RNA interference (RNAi) has been shown to improve chip and fry color in cold‐stored potato tubers by lowering reducing sugar contents . The present study was conducted to determine whether reduced VInv expression could also mitigate the loss of potato processing quality caused by senescent sweetening.…”

VInv activity contributes to reducing sugar accumulation during senescent sweetening. Sucrose breakdown during frying may contribute to chip darkening. Suppressing VInv expression increases the storage period of the chipping potato crop, which is an important consideration, as potatoes with reduced VInv expression are entering commercial production in the USA. © 2017 Society of Chemical Industry.

“…The acid invertase is involved in sucrose partitioning, cell elongation and enlargement, sugar signal transduction and environmental stimuli response [7,8]. For example, the expression of acid invertase is regulated by sugar, pathogenic bacteria and freezing injury [9][10][11][12]. In addition, acid invertase is also regulated by auxin, gibberellin, cytokinin and abscisic acid [1].…”

Plant invertases comprise a family of enzymes that catalyze the irreversible hydrolysis of sucrose into glucose and fructose, which plays a crucial role in carbohydrate partitioning and regulating plant growth and development. However, currently, there is little information on the roles of invertases in the development of pear trees. In this study, we performed genome-wide identification of a total of 23 invertases from the predicted genome data of the pear plant (Pyrus bretschneideri R.). Based on phylogenetic analysis, the pear invertases could be clustered into 13 acid invertase genes and 10 alkaline/neutral invertase genes. Chromosome location showed that tandem duplication and segmental duplication have played an important role in the expansion of acid and neutral/alkaline invertases in pear plants. Evolutionary analysis of invertases from pear and two model plant species (Arabidopsis thaliana and Oryza sativa) indicated that the evolutionary divergence of invertases occurred before the common ancestor of dicots and monocots. Tissue-specific expression analysis showed that the transcripts of all the identified invertase genes were detectable in various tissues. We hypothesize that the identified invertase genes all participate in regulating pear growth and development.
