Correction: The Tinkerbell (Tink) Mutation Identifies the Dual-Specificity MAPK Phosphatase INDOLE-3-BUTYRIC ACID-RESPONSE5 (IBR5) as a Novel Regulator of Organ Size in Arabidopsis.

The IAA concentration in Fig 3 is incorrect and should be listed as 100nM IAA. The authors have provided a corrected version here.

Fig 3

Root phenotype of ibr5 alleles compared to wild-type.

a. On standard growth media (top panel) the ibr5-3 allele is indistinguishable from the wild-type (Col) whereas in media containing 100nm IAA, the ibr5-3 allele is insensitive to the inhibition of root growth seen in the wild-type (bottom panel). b. The tink/ibr5-6 allele shows reduced root growth compared to Ler on media with or without 100nm IAA and displays a slightly significant difference (p value ≤ 0.3) in root growth inhibition on 100nm IAA compared to the wild-type (c). Scale is 1cm. Values are shown as mean ± SEM where n = 20.
