Identification of additional l2 mutant alleles. A, Aberrant splicing of L2 in the Lutescent Fireball cultivar. RT-PCR amplification of cDNA fragments corresponding to L2 from Fireball (F) and Lutescent Fireball (LF) cultivars. The approximate size of the DNA fragments is indicated. B, Relative positions and nucleotide changes observed in the l2 mutant alleles identified in the Lutescent Fireball cultivar and in the EMS derived mutant e3779. White boxes correspond to exons. C, Consequences of l2 mutant alleles on the predicted L2 protein sequence.
