Figure 6.

Comparisons of expression levels of nine MIKC-type MADS-box genes obtained by qRT-PCR analysis in different floral buds during germination in C. paliurus. PA-M: male floral buds in protandrous type; PG-M: male floral buds in protogynous type; PA-F: female floral buds in protandrous type; PG-F: female floral buds in protogynous type. All RT-qPCRs for unigenes were accomplished in triplicate, with two repeats per experiment. Error bars indicate SD, and different lowercase letters (a–d) represent significant differences among the three samples at p < 0.05.
