Abstract Potato (Solanum tuberosum L.) is susceptible to enzymatic browning after fresh processing, resulting in color change and potential alteration in the nutritional quality. In this study, a popular potato cultivar, Feiwuruita, was used to profile the metabolites involved in color and nutritional quality changes in fresh shreds stored at 0 and 4 h at 25°C (designated CK and CK4H, respectively). The shreds turned brown within 4 h of storage. In all, 723 metabolites consisting 12 classes of compounds were detected in the samples, largely lipids, phenolic acids, alkaloids, amino acids and derivatives, flavonoids, organic acids, nucleotides and derivatives. Of these,… More >

Abstract Inorganic phosphate (Pi) is one of the main nutrients necessary for plant growth. Phosphate transporters mediate the acquisition, transport and recycling of phosphate, which is essential for plant growth and development. Although PHT1 has been reported in many plants at home and abroad, it is rarely studied in potato. Therefore, it is of great significance to study the PHT1 family members in order to understand the molecular response mechanism of potato in low phosphate state. In this study, a total of 6 potato PHT1 genes were identified and isolated. It was found that after the expression of different members of… More >

Abstract The progress and development of crops like potato are harmfully affected by increased heat stress throughout the world. Stress caused by increased heat adversely affects germination and seedling growth which result in a reduced crop development and yield. The present research was carried out to know the influence of heat stress on growth indices and physiological processes of potato (Solanum tuberosum L.). The heat stresses C- Control (25 °C); T1-45 °C, and T2-40 °C were applied in separate growth chambers to the plants, after 25 days from their germination. Increased heat stress considerably decreased the chlorophyll a and b pigments… More >
