Fig. 4From: Comprehensive molecular evaluation of the histone methyltransferase gene family and their important roles in two-line hybrid wheatThe number of HMT genes identified per subfamily in A Arabidopsis, B rice, and C wheat. D The ratio of total HMT gene numbers to those in all subfamilies is shown for wheat: rice (red) and wheat: Arabidopsis (purple). In D the expected ratio (3:1) is indicated by a black line, and asterisks mark a significant deviation from the expected value using χ2 test, P < 0.05Back to article page
