Rice chromosome 10 gene model distribution and expression. (a) Characterization of TIGR nonredundant protein-coding gene models. Model density, array detection rate, number of signal oligos, number of intergenic TARs, and cumulative length (in kilobases) of masked oligos are calculated in 100-kb windows along the length of chromosome 10, and are represented by color-coded vertical bars. A scale representing the physical length of chromosome 10 is shown at the bottom of the panel. The arrowhead delimits the division of domain I and domain II as indicated in the text. Note that the centromere is located at a position around 7 to 8 Mb in chromosome 10. (b) Gene model density and array detection rate of the BGI japonica annotation. (c) Gene model density and array detection rate of the BGI indica annotation. (d) Comparison of the S Arrays and the N Arrays using the BGI japonica annotation. Log2 (S/N) of the hybridization intensity was calculated for individual models (top) and the mean intensity of all models in 100-kb windows along the length of chromosome 10 (bottom).
