Comparison of transcriptomes as they relate to morphology. Heat maps illustrate differences generated by angle of the growth plate (Agp) or genetic differences. a Genes with altered transcription within Col-0 compared to the control of Agp 90°. Col-0 had 22 gene transcripts altered at Agp 45 ° and 6 altered at Agp 135°. Data in the heat map corresponds with data in Table 1. b Genes with altered transcription within WS compared to the control of Agp 90°. WS had 66 altered gene transcripts at Agp 45° and 40 altered at Agp 135°. Data in heat map corresponds with data in Additional file 1: Table S2. c Transcript comparisons between Col-0 and WS ecotypes – a genetic comparison – with morphological diagrams corresponding to each of the categories (I-VI) of gene expression profile. Transcripts between the ecotypes were removed if they were altered at the same level at all Agp. For example, if the transcript for Gene A was downregulated 2 fold in all conditions, it was removed. This comparison between Col-0 and WS had 128 altered gene transcripts at Agp 90°, 88 altered between Col-0 and WS at Agp 45°, and 133 altered between Col-0 and WS at Agp 135°. Data in heat map corresponds to data in Additional file 2: Table S3.
