    • ‘Synthesis of the full spectrum of flavour precursors may resume if the callus is allowed to redifferentiate or regain a capacity for phototrophic metabolism.’
    • ‘The high nutrient demands of microbial degradation imply furthermore a competition for nutrients between heterotrophic degradative and phototrophic productive processes.’
