Production of flavanone-neohesperidosides in Citrus embryos.
Grapefruit (Citrus paradisi) tissue cultures were examined for qualitative and quantitative changes in flavanone-neohesperidoside content during somatic embryogenesis. Embryos cultured in vitro contain naringin and a rhamnosyl-transferase activity which is capable of rhamnosylating position 2 on the flavanone glucosides. Rhamnosylation is carried out only in embryos cultivated on solid medium but not in embryos grown in suspension cell cultures.
