The main carotenoids in the extracts from the YF callus were lutein and zeaxanthin, whereas those in the extracts of the WF callus were lutein, zeaxanthin, β-cryptoxanthin and β-carotene. Lutein was the main pigment in both calluses (YF andWF). It is important to point that lutein accumulation occurs not only in specialized tissue, it has been reported that on undifferentiated tissue (callus), chromoplasts are the organelles where carotenoid synthesis and storage occurs
