Research Interests
  • Understanding the basic processes underlying the interactions between fruits and pathogenic fungi.
  • Studying biochemical and molecular mechanisms that are controlled by fungal virulence and fruit resistance factors.
  • Using transformation-mediated gene disruption to create strains of pathogenic fungi that are specifically mutated in their ability to make cell-wall degrading enzymes and other pathogenicity factors. These mutants are tested for their ability to cause disease and to elicit defense responses.
  • Studying the biochemical basis for modulation of pathogenicity factor affecting the transcription expression of nitrogen metabolism, ammonia secretion and the effect on the modulation of local pH.
  • Reduction of postharvest losses in deciduous and subtropical fruits.
