Major motifs of protein kinase domain in predicted rice LKs.

*[9].**If the bits value (see fig. S2) of the amino acid at this position is smaller than 0.5, it is represented with x; 1> bits ≧0.5, with lowercase; 2> bits ≧1, with capital letter; 3> bits ≧2, with bold capital; bits >3, with underlined capital letter in bold.***The sequences of the human protein kinases come from Manning et al.(2002).
