Distribution map of EST and repeat sequence abundance, and length in ten chromosome regions of <i>Arabidopsis thaliana</i>, <i>Brachypodium distachyon</i>, <i>Glycine max</i>, <i>Oryza sativa</i>, <i>Vitis vinifera</i>, and <i>Zea mays</i>.

The blue line represents the changing trend in EST abundance, the yellow line represents repeat sequence abundance, the red line represents repeat sequence length, and the green line indicates the middle point of chromosomes. The value of Y-axis indicates the number of EST abundance.
