Fig. 3: Development of flower buds and gene expression profiles.
From: Evidences for a role of two Y-specific genes in sex determination in Populus deltoides
a Morphology of the male and female flower buds at developmental stages T1–T4 defined in the text. b Longitudinal sections of male and female inflorescences at T1 and T3. The red arrows point to the floret primordia, and the yellow arrow denotes the anther primordium. Three independent samples were observed with similar results. c Gene expression profiles in the 8 flower development stages described in the text. Values shown are the mean ± SD from three biological replicates (*P < 0.05; **P < 0.01, two-sided Student’s t test). The data for c are provided as a Source Data file.
