Evidences for background dependence of nonadditive phenomena at the transcriptional level. a The expression patterns in 1, 2, and 3mm of rice young panicles among 9311, Peiai 64s (PA64S), and their hybrid Liangyoupei 9 (LYP9); A, D, OD, POD, and NOD represent the expression patterns, additive, dominant and overdominant, positive overdominant, and negative overdominant, respectively. b Consistency for different expression patterns among different tissues (including 1, 2, and 3-mm young panicles) in the combination of LYP9. 1&2mm means the same expression pattern in 1 mm and 2 mm panicles, and similar for other symbols of 2&3mm and 1&2&3mm. ND and PD mean negative and positive dominant effect, respectively. NOD and POD mean negative and positive overdominant effect, respectively. c Sum of determination coefficient between transcription factors and their target genes with different expression patterns in rice young panicles among 9311, Peiai 64s (PA64S), and their hybrid Liangyoupei 9 (LYP9)
