JA-sufficient phenotypes in transgenic Arabidopsis constitutively expressing the TaAOC1. A, Two-week-old VC and two transgenic lines (OE1 and OE2). Bar = 1 cm. B, Root length of 2-week-old VC, OE1, and OE2 seedlings. Error bars represent the sd from at least 30 plants. C, Measurement of JA levels in the rosette leaves of VC, OE1, and OE2 plants, with or without wounding. Data are presented as means ± sd, and columns marked with asterisks indicate significant differences from the VC line using Student’s t test (P < 0.05). Error bars represent the sd from three biological replicates. Each replicate contained at least 30 plants. [See online article for color version of this figure.]
