Genetics. In the article “A Ds insertion alters the nuclear localization of the maize transcriptional activator R” by Yanhong Liu, Mary Alleman, and Susan R. Wessler, which appeared in number 15, July 23, 1996, of Proc. Natl. Acad. Sci. USA (93, 7816–7820), the authors request that the following correction be noted. On page 7819 in the legend to Figure 6, “preimmune sera” should be “nonimmune rabbit immunoglobulins.” Also, due to a printer’s error, in the legend to Figure 6, “Sr antibody” should be “Sn antibody.”
