Figure 4From: Partial functional conservation of IRX10 homologs in physcomitrella patens and Arabidopsis thalianaindicates an evolutionary step contributing to vascular formation in land plantsThe Physcomitrella IRX10 homolog expressed in the Arabidopsis irx10 irx10-L double mutant. A) Arabidopsis irx10 irx10-L double mutant partially complemented by p35S:PpGT47A. B) Rosette diameter and inflorescence height of PpGT47A complemented Arabidopsis plants. Data obtained from between 2 and 7 biological repeats per line. Each line represents one independent transformation event. C) Sections from 8-week old basal stem tissue of Columbia wild-type, Arabidopsis irx10 irx10-L double mutant complemented with the Physcomitrella IRX10 homolog, and the Arabidopsis irx10 irx10-L double mutant. D) Higher magnification of the safranin stained tissues shown in C. Safranin staining in the cell corners of the irx10 irx10-L double mutant is indicated by arrowheads. Scale bar 50 ÎĽm (C) or 20 ÎĽm (D).Back to article page
