Fig. 4.

Dynamics of allele-specific expression of PcG genes during endosperm development. The dots above the first dash line indicated only transcripts derived from maternal allele could be detected. The dots nearby the middle dash line indicated both transcripts from paternal allele and maternal allele could be detected simultaneously. The dots below the third dash line indicated only transcripts derived from paternal allele could be detected. Each data has been confirmed by three independent experiments
