“…By disrupting all four copies of StPPO2 the authors achieved a dramatic reduction in tuber PPO activity (up to 69%) and enzymatic browning (73%). The findings presented by González et al are consistent with the reported reduction in potato browning achieved by silencing the StPPO2 gene using RNAi (Richael, 2021 ).…”

“…This means the Innate ® Cultivate and other GM potato cultivars were generated by J.R. Simplot Co. suppressing Asparagine synthetase 1 (Asn1), polyphenol oxidase 5 (Ppo5), starch phosphorylase L (PhL), glucan water dikinase (R1) and, in some cultivars, vacuolar invertase (VInv). The resulted GM potato does not develop black-spot bruise due to less Ppo5; when fried, it produces much less acrylamide due to less asparagine (lower Asn1 activity) and is not as brown as the original potato due to having fewer reducing sugars (less R1 and VInv activity) [69].…”

The development of new, more productive varieties of agricultural crops is becoming an increasingly difficult task. Modern approaches for the identification of beneficial alleles and their use in elite cultivars, such as quantitative trait loci (QTL) mapping and marker-assisted selection (MAS), are effective but insufficient for keeping pace with the improvement of wheat or other crops. Metabolomics is a powerful but underutilized approach that can assist crop breeding. In this review, basic methodological information is summarized, and the current strategies of applications of metabolomics related to crop breeding are explored using recent examples. We briefly describe classes of plant metabolites, cellular localization of metabolic pathways, and the strengths and weaknesses of the main metabolomics technique. Among the commercialized genetically modified crops, about 50 different metabolically altered plants have been identified in the International Service for the Acquisition of Agri-biotech Applications (ISAAA) database. These plants are reviewed as encouraging examples of the application of knowledge of biochemical pathways. Based on the recent examples of metabolomic studies, we discuss the performance of metabolic markers, the integration of metabolic and genomic data in metabolic QTLs (mQTLs) and metabolic genome-wide association studies (mGWAS). The elucidation of metabolic pathways and involved genes will help in crop breeding and the introgression of alleles of wild relatives in a more targeted manner.

“…Other than postharvest interventions, breeding strategies addressing the phenylpropanoid or PPO biosynthesis pathway could also be an effective solution ( Hunter et al, 2017 ). There have been several successful attempts to silence PPO expression and thereby reduce discolorations in fresh produce, resulting in commercial applications such as Arctic® apple and Innate® Potato ( Richael, 2021 ; Stowe and Dhingra, 2021 ). However, it is possible that the suppression of PPOs results in an increased susceptibility toward disease, due to their role in plant defense ( Kampatsikas et al, 2019 ).…”

Many fruits and vegetables suffer from unwanted discolorations that reduce product quality, leading to substantial losses along the supply chain. Witloof chicory (Cichorium intybus L. var. foliosum), a specialty crop characterized by its unique bitter taste and crunchiness, is particularly sensitive to various types of red and brown discolorations. The etiolated vegetable suffers from three predominant color disorders, i.e., core browning, internal leaf reddening, and leaf edge browning. Additionally, several less frequently observed color disorders such as hollow pith, external red, and point noir can also negatively affect crop quality. In this article, we bring together fragmented literature and present a comprehensive overview of the different discoloration types in chicory, and discuss their potential underlying physiological causes, including laticifer rupture, calcium deficiency, and a disturbed water distribution. We also describe the role of environmental cues that influence discoloration incidence, including cultivation and postharvest storage conditions such as forcing and storage temperature, root ripeness and the duration of the forcing process. Finally, we zoom in on the underlying biochemical pathways that govern color disorders in witloof chicory, with a strong emphasis on polyphenol oxidase.
