Genome-wide transcriptome profiles of rice hybrids and their parents.

ABSTRACT: Heterosis is a widely studied phenomenon in several plant species. However, its genetic basis still remains to be elucidated. In this study, we used RNA-seq data from two rice genotypes and their reciprocal hybrids, and used a combination of transcriptome profiling and allele-specific expression analysis to identify genes that are differentially expressed in the hybrids and their parents or expressed in an allele-specific manner. The differentially expressed genes (DEGs) were identified by a pairwise comparison of the four genotypes. Detailed annotation of DEGs suggested that these genes showed enrichment in some gene ontology categories, and they tend to have tissue-specific expression patterns compared to all genes. A total of 1033 (10.24%) of 10,195 genes with informative single nucleot
