Gibberellin production variability in Fusarium fujikuroi and its contributory factor

Abstract

  Fusarium fujikuroi is the fungal pathogen of rice bakanae disease. This fungus is known to produce secondary metabolites including gibberellin that function as a plant hormone and fumonisin as a mycotoxin. Two groups were discovered in F. fujikuroi derived from not only diseased rice plant but also from various resources by phylogenetic analyses and investigation of gibberellin and fumonisin producibility. In this proceeding, gibberellin production difference between these groups and its contributory factor in F. fujikuroi were presented.
