Green Fluorescent Protein as a Reporter To Monitor Gene Expression and Food Colonization by Aspergillus flavus

摘要

Transformants of Aspergillus flavus containing theAequorea victoria gfp gene fused to a viral promoter or the promoter region and 483 bp of the coding region of A. flavus aflR expressed green fluorescence detectable without a microscope or filters. Expression of green fluorescent protein fluorescence was correlated with resistance to aflatoxin accumulation in five corn genotypes inoculated with these transformants.
