Abstract

Mango, a typical respiratory climacteric fruit, is susceptible to a short shelf life and quality deterioration during postharvest ripening. Although low temperature can prolong the storage time significantly, its effects on fruit quality have yet to be elucidated. Through a combination of transcriptome and metabolome analyses, this study aimed to elucidate the effects of low-temperature storage on the biosynthesis of volatile organic compounds (VOCs), flavonoids, sucrose, and the degradation of organic acids in mango. Carbohydrate-related metabolism maintained high activity when stored at 13 °C by upregulating the expression of certain gene members in the neutral invertase (NI), sucrose phosphate synthase (SPS), and sucrose synthase (SS) families. Similarly, low temperature suppressed the expression of an ethylene receptor (ETR) gene (mango007369), compensated by another member in the ETR family (mango016667). The increased accumulation of flavonoids when stored at l3 °C aligned with the enhanced expression of genes related to flavonoid synthesis in mango fruit, such as flavanone 3-hydroxylase (F3H), flavonoid 3'-hydroxylase (F3’H), and chalcone isomerase (CHI). However, in comparison to storage at 30 °C, low-temperature storage reduced the total soluble solids (TSS) but increased the accumulation of several organic acids. Low temperature almost entirely inhibited the synthesis of VOCs, which further decreased the commercial quality. The findings revealed the impact of storage temperature on mango quality and offered insights for maintaining quality at low temperatures.
