Secondary Evolution of a Self-Incompatibility Locus in the Brassicaceae Genus Leavenworthia

Alignment of amino acid sequences of Leavenworthia and A. lyrata SCRL alleles.
The A. lyrata AlSCRL sequence corresponds to NCBI Gene ID_9305018. The a1-1 and a1-2 LaSCRL alleles are from the SI race and have full open reading-frames, while the a2 and a4 alleles are from SC races and encode truncated proteins. In the a1-1 and a1-2 alleles, blue box highlights the predicted signal peptide; arrow indicates conserved position of the intron; red arrowhead marks the predicted cleavage site of the a1-1 and a1-2 preproteins. Cysteines found in the predicted mature protein sequences are colored in red. Asterisks represent stop codons. Hyphens represent gaps that were introduced to optimize the alignment.
