FIG. 4.

Amino acid sequence of Ha-BtR and resistance allele r1 deduced from cDNA. Identical residues are designated by dashes. An asterisk shows the premature stop codon in r1. Protein sequence analysis was done by using the Simple Modular Architecture Research Tool (http://smart.ox.ac.uk). Horizontal arrows specify start sites of putative domains. SIG, signal peptide predicted by using SignalP 3.0; EC, cadherin repeat; MPR, membrane-proximal region; TM, transmembrane domain; CYT, cytoplasmic domain.
