Expression patterns of anther and pollen development genes and PCD-related genes in male and female flowers. (A) Heatmap analysis of the important anther and pollen development genes and PCD-related genes in male and female flowers; I, Genes highly expressed in C1, X1, and X2; II, Genes highly express in C1, X1, X2, and X3. (B–G) Expression levels of MS1, MS2, MYB103, MYB33, SPL/NZZ, and EXS1/EMS1 based on FPKM and qRT-PCR data. (H–M) Expression levels of SORB1, AGP16, BAG7, LSD1, SRLK2, and ROHBA based on FPKM and qRT-PCR data. Error bars indicate SD. Different letters represent significant difference in mRNA levels (p < 0.05).
