Fig. 1From: B chromosome contains active genes and impacts the transcription of A chromosomes in maize (Zea mays L.)FISH identification of B chromosome number. The red signal is digoxingenin-labeled ZmBs. The B chromosome number was confirmed by counting ZmBs signals and total chromosome number. (a) B73 + 0B, (b) B73 + 1B, (c) B73 + 6Bs. Arrows indicate the B chromosome. Bar = 5 μmBack to article page
