摘要：

We have investigated possible collinearity between the genomes of rice and Arabidopsis by comparing 126 annotated and mapped rice BAC Sequences (similar to 20 Mb of sequence) with the annotated and complete Arabidopsis genome (similar to 115 Mb). Although we were able to identify several re.-ions in which gene order is preserved, they are relatively small, and are interrupted by noncollinear genes. Computer simulation showed that these microscale collinearities are above the expectation for a random process. Oil the other hand, the order of exons within homolo.-ous.-enes (<2.5 kb) was preserved, as expected.
