Abstract Background Transposable element TE -related genes comprise a significant portion of the gene catalog of grasses although their functions are insufficiently characterized. The recent availability of TE-related gene annotation from the complete genome sequence of rice Oryza sativa has created an opportunity to conduct a comprehensive evaluation of the transcriptional activities of these potentially mobile elements and their related genes. Results We conducted a genome-wide survey of the transcriptional activity of TE-related genes associated with 15 developmental stages and stress conditions. This dataset was obtained using a microarray encompassing 2 191 unique TE-related rice genes which were represented by oligonucleotide probes that were free from cross-hybridization. We found that TE-related genes exhibit much lower transcriptional activities than do non-TE-related genes although representative transcripts were detected from all superfamilies of both type I and II TE-related genes. The strongest transcriptional activities were detected in .
