Sequence comparisons of three wild-type Bronze-1 alleles from Zea mays

We have sequenced genomic clones of two wild-type Bronze-1 (Bz1) alleles, and a cDNA clone from a third wild-type Bz1 allele from maize. Two overlapping transcripts initiate at least 250 bp apart. The first AUG codon after the shorter and more abundant transcript cap site(s) begins the longest open...

Description
Summary:We have sequenced genomic clones of two wild-type Bronze-1 (Bz1) alleles, and a cDNA clone from a third wild-type Bz1 allele from maize. Two overlapping transcripts initiate at least 250 bp apart. The first AUG codon after the shorter and more abundant transcript cap site(s) begins the longest open reading frame. The transcript is preceded by a putative TATA box, but not a recognizable CAAT box. The bz1 gene contains a single intron, and exhibits a strong bias for codons with the highest G+C content. Sequence polymorphisms among the Bz1 alleles include deletions/additions, a transposable element insertion, and single base pair substitutions.
