| red pigment in cob and pericarp. Colorless aleurone ears showing expression of the most common alleles of the p1 locus. From left to right: P1-rr, red pericarp and cob; P1-wr, colorless pericarp red cob; P1-rw, red pericarp white cob; p1-ww colorless pericarp white cob; P1-vv, variegated pericarp and cob (caused by transposon Ac insertion in a P1-rr gene, note the twinned light variegated/red sectors on the upper portion of the ear). The end ear is P1-ovov, orange variegated pericarp and cob, caused by transposon Ac insertion in a P1-rr gene in the opposite orientation as in the P1-vv allele. The multikernel white sector on the left side the ear results from transposon Ac-induced recombination and deletion of the P1 gene. (Photo courtesy T. Peterson). | photo: three ears segregating for purple or red color (A1) vs. colorless aleurone (a1/a1) on ears with, respectively, colorless pericarp (p1/p1); brown pericarp (with P1-rr/- and the A1-b allele); and red pericarp (P1-rr) with the common A1 allele. |
