Transcriptome constitution during development. (a) Transcriptome size of the seven tissue samples. (b) Venn diagram showing the overlaps between anther stages (combined according to similarities in development) and pollen. The number below each stage designation is the total transcripts detected in that stage(s). (c) Analysis of the progression of transcriptome changes during anther development. The approximately 15,950 transcripts shared by all 6 stages are not shown. Numbers above the x-axis represent transcripts present in the indicated stage that are: stage specific (black); not present in the prior stage but shared with another stage (orange); or shared with the prior stage but missing in at least one other stage (green). Numbers below the x-axis represent transcripts present in the prior stage (from the category with a darker shade of the same color) that are not detected in the current stage. For tissue stage information see Figure 1a. Table S1 in Additional data file 1 reports the number of transcripts in each component of the histogram.
