Figure 2From: The bHLH transcription factor SPATULA regulates root growth by controlling the size of the root meristemIncreased growth of spt roots. (A) Primary root length (n = 90) at 7, 10 and 13 DAG. (B) Primary root growth rate (n = 30) expressed as mm/hr. Error bars indicate standard error. Asterisks indicate values significantly different from wild type at P < 0.05.Back to article page
