PHENYLPHENALENONE-TYPE PHYTOALEXINS AND PHYTOANTICIPINS FROM SUSCEPTIBLE AND RESISTANT CULTIVARS OF MUSA SPECIES. ITS POTENCIAL FOR ENGINEERING RESISTANCE TO FUNGI AND NEMATODES INTO BANANA
Cultured somatic embryos of Musa acuminata also produced, after eight weeks, the same compounds, and the isolation and characterisation of several biosynthetic intermediates led us to postulate a biosynthetic pathway for this new-type phytoalexins. More recently we have also found that several resistant Musa cultivars produce in much larger quantities and like phytoanticipins (constitutive natural antibiotics), the same family of compounds, suggesting that this type of phytoalexins play an important role for resistance to fungal diseases. These results may open a new way to engineer resistance into banana plants.
