PLANT BIOLOGY. For the article “Amino acid polymorphisms in Arabidopsis phytochrome B cause differential responses to light,” by Daniele L. Filiault, Carolyn A. Wessinger, Jose R. Dinneny, Jason Lutes, Justin O. Borevitz, Detlef Weigel, Joanne Chory, and Julin N. Maloof, which appeared in issue 8, February 26, 2008, of Proc Natl Acad Sci USA (105:3157–3162; first published February 14, 2008; 10.1073/pnas.0712174105), the authors note that, in the Fig. 4 legend, the graph bars were identified incorrectly. This error does not affect the conclusions of the article. The figure and its corrected legend appear below.
Fig. 4.
Phenotypic association with PHYB polymorphisms. For each condition and polymorphism, the bar height indicates average hypocotyl length of accessions with Cvi (gray bars) or Ler (white bars) alleles. Hypocotyl data are from ref. 21 and represent an average of 14 hypocotyls per condition for each of 140 accessions. Error bars indicate SEM.
