Transcriptomic profiling in maize inbred lines and their reciprocal hybrids. (a) Distribution of the mapped reads in the maize genome for mRNA sequencing (mRNA-seq) libraries from shoots and roots. For each organ, the mean percentages of both hybrids and parents are shown. (b) Proportion of mRNA transcripts identified in shoots and roots by mRNA-seq, according to gene annotations supported by expressed sequence tag (EST) or full-length cDNA data. For each organ, the mean percentages of both hybrids and parents are shown. (c) Functional categories of genes showing organ-specific expression. For each organ, only genes whose transcripts were detected in both hybrids and parents were included in the analysis. False-discovery rate adjusted P-values: *P<0.05 and **P<0.01, respectively.
