Figure 4. Distribution of SSRs (lower panel with triangles) and
EST clusters (upper panel with circles) per Mb on each of the
12 chromosomes of rice. Numbers along the graphs represent
the total numbers of SSRs or genes mapped to each chromosome
by ePCR or based on TIGR gene indices, respectively,
divided by the total length of genomic sequence available for
each chromosome (as of November 2002).
