英文摘要	To study how changes in gene regulation shape phenotypic variations in rice, we performed a comparative analysis of genome expression in the heading-stage panicle from six lineages of cultivated and wild rice, including Oryza sativa subsp. indica, japonica and javanica, O. nivara, O. rufipogon and O. glaberrima. While nearly three-quarters of the genes are expressed at a constant level in all six lineages, a large portion of the genome, ranging from 1767 to 4489 genes, exhibited differential expression between Asian domesticated and wild rice with repression or down-regulation of genome expression in Asian cultivated rice as the dominant trend. Importantly, we found this repression was achieved to a large extent by the differential expression of a single member of paralogous gene families. Functional analysis of the differentially expressed genes revealed that genes related to catabolism are repressed while genes related to anabolism up-regulated. Finally, we observed that distinct evolutionary forces may have acted on gene expression and the coding sequences in the examined rice lineages.
