Integrated transcriptomics and metabolomics analysis reveal LcSWEET12 regulating sugar accumulation in litchi (Litchi chinensis Sonn.).
Soluble sugars constitute one of the key quality-determining traits of litchifruit and contribute substantially to flavour formation. 'Heli' (HL) is a traditional litchi cultivar, and its bud mutant 'Dongtianxianli' (DTXL) displays brighter fruit colour, higher soluble-sugar content and lower acidity. To dissect the mo...
