Abstract

Segmental duplication is particularly frequent within plant genomes and the ability of the original single-copy gene to gain a new function for the change of regulatory elements is one of the prominent consequences of duplication. Thus, it is important to study the pattern of conserved non-coding sequence (CNS) between paralogous genes. We report the result of a survey of CNSs among paralogous regions in rice (Oryza sativa L.), as well as the comparison of CNS dataset between rice and Arabidopsis thaliana. Some common properties, such as the change of A + T content near the CNS boundaries and CNS are enriched in regulatory genes, were observed. However, the content of CNSs differs between rice and Arabidopsis, and it is interesting that the rice metabolic network includes both CNS-poor and CNS-rich genes, which indicated a fine-tuned metabolic network presents in rice.
