Fig. 3. Comparison of the TTR1 (Est) and ttr1 (Col-0) amino acid sequences. TTR1 encodes a “TNL”-type gene. The predicted sequences of TTR1 in Est and ttr1in Col-0 were aligned and compared using the DNAMAN software. The sequences of the TIRNBS regions in Est and Col-0 were identical, but 21 amino acid differences were observed in the LRR region. Identical amino acids are marked by dashes (-), and amino acid differences are indicated by asterisks (*).
