Figure 3.

Haplotype diversity of the LRK gene cluster in 13 rice accessions. Based on the presence/absence of LRK1, the divergence of LRK2, and the sequence variation before the 5′ coding region of LRK2 to LRK7 (designated by PM2 to PM7), 13 haplotypes (A–M) were detected among 13 rice accessions. Different shaded rectangles indicate the size and sequence variation in the polymorphous regions. The small sequence variation within a size of 2 bp in the segments represented by the same rectangles are not shown in this figure. To the left is the phylogenic tree generated by ClustalX using the neighbor-joining method based on the divergent sequences in the LRK cluster.
