Aspartate kinase and the synthesis of aspartate-derived amino acids in wheat.

abstract：MAIN CONCLUSION:Expressing an RNAi construct in maize kernels that targets the gene for alpha-amylase in Aspergillus flavus resulted in suppression of alpha-amylase (amy1) gene expression and decreased fungal growth during in situ infection resulting in decreased aflatoxin production. Aspergillus flavus is a saprophyti...
