According to E. H. Coe, Jr. and M. G. Neuffer (Corn and Corn Improvement, G. F. Sprague, ed.), anther fluorescence is displayed by bz-null alleles. The basis for this fluorescence is variously ascribed as likely to quercetin (Coe and Neuffer, Corn and Corn Improvement), or not ascribed to quercetin (R. L. Larson and E. H. Coe, Jr., Biochem. Genetics 15:153-56).
We have determined the following:
These results are not surprising in view of H. K. Dooner's finding that bz-m4 is not a null allele (Cold Spring Harbor Symp. Quant. Biol. 45:457-462).
