Abstract

Two chalcone synthase genes in maize have been cloned and molecularly
characterized to be the C2 and the Whp (white pollen) locus. The two genes have
highly homologous exon sequences but differ considerably in sequences 5'
upstream and 3' downstream of the coding region, as well as in their introns.
Northern and Western experiments of chalcone synthase expression in various
tissues and in different genotypes indicated that C2 and Whp are differently
regulated. The expression of Whp in maize aleurone is dependent on the presence
of the recessive allele of the gene intensifier (in). The regulatory effect of
in on Whp expression is not detectable at the transcriptional level, but seems
to take place during translation.
