Selective upregulated gene groups in the transcriptome overexpressing AtWDR26. Transcriptome of transgenic Arabidopsis seedlings overexpressing AtWDR26 was analyzed by a DNA microarray. Upregulated genes associated with chloroplast signaling (A), auxin signaling (B), cell wall flexibility (C), Zn uptake (D), transcription factors of AP2/ERF family (E), and disease resistance (upregulation levels > 5-fold) (F).
