Fig. 1. — Cladogram and amino acid sequence alignment of tomato PYR/PYL ABA receptors. (A) Cladogram of the multiple sequence alignment of tomato and Arabidopsis PYR/PYL receptors, indicating three major subfamilies and the ungrouped 2g076770. Those tomato receptors further described in the text are in bold face. (B) Sequence and secondary structure alignment of tomato PYR/PYL ABA receptors and Arabidopsis PYR1 protein. The predicted secondary structure of the tomato proteins was indicated, taking as a model the crystallographic structure of PYR1 (Protein DataBank Code 3K90) and using the Espript interface (http://espript.ibcp.fr/). Boxes indicate the position of the gate and latch loops. Black asterisks mark residues K59, A89, E94, R116, Y120, S122, and E141 of PYR1 involved in ABA binding. Grey asterisks mark conserved residues of the tomato receptor family that differ in tomato 2g076770 protein. (This figure is available in colour at JXB online.)
