Figure 7.
EPFL1, EPFL2, EPFL4, and EPFL6 synergistically regulate stem and pedicel elongation with EPFL4 and EPFL6 playing the key role. A, Height of fully grown plants (n = 27 to 46 except er erl1 erl2, n = 12). B, Lengths of mature pedicels on the main stem (n = 100 to 120). C, Number of siliques on the main stem (n = 10). A to C, Bars represent the average; error bars represent sd. Values significantly different from er-105 are indicated by asterisks (based on Student t test; P < 0.001). D, 6-week-old plants of er-105, epfl1-1 epfl2-1 epfl4 epfl6, and er-105 erl1-2 erl2-1. Scale bar: 1 cm. E, Influorescence apices from the wild type, er, er erl1 erl2, and various combinations of epfl mutants. Bar = 25 mm. All images are under the same magnification in (D) and in (E). wt, wild type.
