Table I. Morphometry of first-node leaf venation patterns in single and double mutants.
All values are means from 10 first-node leaf measurements ± sd. Numbers in boldface indicate significantly different (P < 0.05) values of the single mutants compared with their wild types or of the double mutants compared with their parental single mutants. For icu13 35Spro:MP and icu13 iaa12-1, values in boldface are significantly different (P < 0.05) from those of icu13.
