Figure 3.

Frequency distribution of different categories of R-like genes and defense response genes on rice chromosomes 11 and 12. The miscellaneous category includes genes showing high homology with putative disease resistance proteins and defense response category includes genes showing high homology to chitinases, glucanases and thaumatin-like proteins. (LZ, leucine zipper; NBS, nucleotide binding site; LRR, leucine rich repeat; TM, trans-membrane).
