Abstract Background It was proposed that differentially-expressed genes aside from genetic variations affecting protein processing and functioning between hybrid and its parents provide essential candidates for studying heterosis or hybrid vigor. Based our serial analysis of gene expression SAGE data from an elite Chinese super-hybrid rice LYP9 and its parental cultivars 93-11 and PA64s in three major tissue types leaves roots and panicles at different developmental stages we analyzed the transcriptome and looked for candidate genes related to rice heterosis. Results By using an improved strategy of tag-to-gene mapping and two recently annotated genome assemblies 93-11 and PA64s we identified 10 268 additional high-quality tags reaching a grand total of 20 .
