Transcriptomic and Metabolic Analyses Elucidate the Metabolomic Variation in Leaf Development of a Calcium-Rich Vegetable (Primulina eburnea)

Primulina eburnea, a plant with longstanding history of traditional medicinal use, has emerged as novel calcium-rich vegetable characterized by remarkable abundance soluble and bioavailable calcium within its leaves. However, most the metabolites produced P. eburnea have not been identified, few studies addressed accumulation nutritional ingredients during leaf development. In present study, we investigated “Gaogai-1” cultivar integrating transcriptomic mestabolomic methods. A total 1041 were identified in During development, flavor components, including amino acids derivatives, organic carbohydrates, decreased their content, which contrasted starch content. Most antioxidant e.g., flavonoids, alkaloids, vitamins, phenolamines, more highly accumulated bud leaves than mature leaves, but terpenes had opposite trend. These results indicate that different developmental stages are suitable for uses could be regarded new type edible vegetable. Furthermore, coding genes related to important components influence values expressions consistent component profiles. Transcription factors may regulate combining co-expression network cis-element binding ability prediction. The high level water-soluble was maintained expression Ca2+/cation antiporter Our uncovered metabolomic molecular evidence mechanisms underlying development This study provides wealth data future utilization improvement cultivars.
