Identification of transcriptome SNPs for assessing allele specific gene expression within a super-hybrid rice Xieyou9308

ABSTRACT: We identified 9325 reliable single nucleotide polymorphisms (SNPs) distributed throughout the genome, of which nearly 68% were represented in R9308 versus Xieqingzao B by CT and GA SNPs. This may indicate that DNA methylation, a heritable epigenetic mark, exists in the parents and their F1 hybrid. Of 2793 identified transcripts with consistent allelic biases, only 480 (17%) showed significant allelic biases during at least one stage, suggesting that trans effects may mediate most transcriptional differences in hybrid offspring. Approximately 67% and 62% of the 480 transcripts showed allelic expression biases towards the R9308 allele at tillering and heading stages, respectively. Transcripts with higher levels of gene expression in R9308 also exhibited R9308 allelic biases in the hybrid. In
