Spatial and temporal expression patterns of PeCYCs genes. (A) Real-time quantitative RT-PCR (qRT-PCR) analysis of the mRNA expression of PeCYC1 and PeCYC2 in various tissues and developmental stages of floral bud. (B) qRT-PCR analysis of the mRNA expression of PeCYC1 and PeCYC2 in different floral organs. (C) Whole mount in situ hybridization of PeCYC1 and PeCYC2 in early floral development stage. Upper left: antisense probe of PeCYC1; upper right: sense probe of PeCYC1; lower left: antisense probe of PeCYC2; lower right: sense probe of PeCYC2. co: column primordium; ds: dorsal sepal primordium; ls: lateral sepal primordium; p: petal primordium. Scale bar: 100 μm.
