Fig. 1. zfl1 and zfl2 gene structures. (A) Alignment of zfl1 and zfl2 proteins deduced from cDNA sequences with RFL (Kyozuka et al., 1998), FLO (Coen et al., 1990) and LFY (Weigel et al., 1992). Repeated leucine residues are indicated by a star. Similar amino acids were identified using BoxShade version 3.1.1. (B) Exon/intron arrangement and sizes (in bp) of zfl1 and zfl2. Five independently derived Mu insertion sites are indicated with triangles and labeled with corresponding mum allele names.
