PLANT BIOLOGY Correction for “Maternal small RNAs mediate spatial-temporal regulation of gene expression, imprinting, and seed development in Arabidopsis,” by Ryan C. Kirkbride, Jie Lu, Changqing Zhang, Rebecca A. Mosher, David C. Baulcombe, and Z. Jeffrey Chen, which was first published February 12, 2019; 10.1073/pnas.1807621116 (Proc Natl Acad Sci USA 116:2761–2766).
The authors wish to note the following: “We note an error in duplicate images of Fig. 4, panel B. As a result, on page 2764, right column, first paragraph, lines 2–5, the following sentence should be redacted: ‘Similarly, maternal AGL91:GUS was completely silenced in the cross using the Wt as the paternal parent (Fig. 4B).’ The correction should restore the accuracy of data in Figure 4 without affecting conclusions in the paper. We apologize for any inconvenience caused by this error.” The corrected Fig. 4 and its corrected legend appear below. The editor has reviewed and approved these changes.
Fig. 4.
AGL91 is paternally expressed and dependent on maternal NRPD1 or RDR2. (A and B) GUS-stained seed images at 4 and 6 DAP in (Left) reciprocal crosses of nrpd1 AGL91:GUSXWt (A) and Wt AGL91:GUSXnrpd1 (B) and (Right) reciprocal crosses of rdr2XWt AGL91:GUS (A) and Wt AGL91:GUSXWt (B) (n = 3 × 100 seeds per cross). (C) GUS-stained seed images at 4 and 6 DAP in the cross of WtX nrpd1 AGL91:GUS. (Scale bars: 0.1 mm for all images.) (D) Images of cleared seeds in the crosses between Wt (Col-0) and nrpd1 at 6 DAP; the area corresponding to the embryo and suspensor is outlined. (Scale bars: 0.1 mm.)
