Expression of candidate genes involved in ovule development. a Ethylene biosynthesis and signal transduction pathway, which comes from a KEGG pathway enrichment analysis [76, 77]. b Expression of candidate genes involved in ethylene biosynthesis and signal transduction. Gene expression was measured by log2Ratio. 11-Apr, 21-Apr, 4-May, 11-May and 21-May represent the pistils of flowers when their development stages were 5, 6, 10, 12 and 14, respectively. However, here, we mainly discussed stage 6, which is the most important development stage in sex differentiation in T. sinensis (for details, see ‘Structure of the Flower’). Different colours from blue to red show the size of the correlation coefficient. c Relative expression levels of 10 selected genes at different stages of floral bud development in MF and HF. Relative expression levels were calculated by the 2-ΔΔCt method with actin as a standard. * represents the P < 0.05 level of significant difference, and ** represents the P < 0.01 level of significant difference in independent-samples t-tests
