“…PoP is the only known carrier of the C Lso that causes ZC disease ( Rondon et al., 2022 ). Due to the lack of effective integrated management approach for ZC, currently, controlling the spread of ZC and VG diseases caused by C Lso is achieved managing the psyllid vector by the use of chemical pesticides, which is costly and poses risks to the environment and human health ( Mora et al., 2021 ).…”

Psyllid yellows, vein-greening (VG), and zebra chip (ZC) diseases, which are primarily transmitted by potato psyllid (PoP) carrying Candidatus Liberibacter solanacearum (CLso), have caused significant losses in solanaceous crop production worldwide. Pathogens interact with their vectors at the organic and cellular levels, while the potential changes that may occur at the biochemical level are less well reported. In this study, the impact of CLso on the metabolism of PoP and the identification of biomarkers from infected psyllids were examined. Using ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) analysis, metabolomic changes in CLso-infected psyllids were compared to uninfected ones. A total of 34 metabolites were identified as potential biomarkers of CLso infection, which were primarily related to amino acid, carbohydrate, and lipid metabolism. The significant increase in glycerophospholipids is thought to be associated with CLso evading the insect vector’s immune defense. Matrix-assisted Laser Desorption Ionization Mass Spectrometry Imaging (MALDI-MSI) was used to map the spatial distribution of these biomarkers, revealing that 15-keto-Prostaglandin E2 and alpha-D-Glucose were highly expressed in the abdomen of uninfected psyllids but down-regulated in infected psyllids. It is speculated that this down-regulation may be due to CLso evading surveillance by immune suppression in the PoP midgut. Overall, valuable biochemical information was provided, a theoretical basis for a better understanding of psyllid-pathogen interactions was offered, and the findings may aid in breaking the transmission cycle of these diseases.

In the pre-Columbian societies of the Americas, a wide range of food practices was observed. However, several countries shared certain staple foods, such as the potato, which has held a significant place in the diet since ancient times. It is important to note that potatoes contain glycoalkaloids, a class of alkaloids with potential toxicity risks when consumed in high concentrations by both humans and animals. This study aims to offer guidance on the presence of glycoalkaloids in potatoes and proposes further research into these compounds in archaeological remains that were utilized as food across all American countries. This recommendation stems from the dearth of studies on this subject, particularly in cases where archaeological discoveries include potato starch granules. In this study, various databases were examined to discover historical insights into the potato and to elucidate the primary aspects of glycoalkaloid chemistry associated with this tuber. The findings underscore the crucial role played by the potato in pre-Columbian cultures of the Americas, particularly in the regions situated along the Andes mountain range. Furthermore, the analysis of its nutritional composition unveiled the prevalence of two key glycoalkaloids in the tuber: α-solanine and α-chaconine. In this research, a comprehensive review of the chemical properties, botanical functions, human metabolism, potential health effects, toxicity thresholds, and available analytical techniques for the detection and quantification of toxic compounds was conducted. The significance of identifying these molecules in archaeological contexts was highlighted, as their presence may prompt investigations into prevalent diseases among historical populations.
