Figure 9.

Sequence analyses of all 98 BRI1 point mutations. A, Sequence analyses among 70 BRI1s or BRLs from 18 sequenced flowering plant species. Mutants showing defective phenotypes all result from mutations of conserved residues. But not all mutations in the conserved residues show defective phenotypes. B, Sequence analyses among all 223 LRR-RLKs of Arabidopsis. Not all mutation sites from mutants with defective phenotypes are conserved, and vice versa. Only the amino acid sites with mutations are shown. New mutants from this study are labeled in red. Previously known mutants are labeled in black. New mutations without significant phenotypes are labeled in gray. The size of the logo is positively correlated to the degree of conservation.
