Citrus phenylpropanoids and defence against pathogens. Part II: Gene expression and metabolite accumulation in the response of fruits to Penicillium digitatum infection

► Expression of phenylpropanoid genes increased in response to pathogen infection. ► Changes in the metabolic profile of flavedo and albedo after Penicillium digitatum infection. ► Flavonoids are induced in citrus fruit in response to pathogen infection.
