Integrated transcriptomic and metabolomic analyses of ‘Guifei’ mango fruit flavor in an endospermic genotype and a mutated genotype without endosperm

•Changes in metabolomic and transcriptomic networks of mango endosperm mutants.•Effects on flavor components and synthesis pathways of esters in the mango fruit.•Revealed genes specific accumulation of carotenoid biosynthetic pathway in mango.
