Erratum: Innovation, conservation, and repurposing of gene function in root cell type development (Cell (2021) 184(12) (3333–3348.e19), (S0092867421005043), (10.1016/j.cell.2021.04.024))

(Cell 184, 3333–3348.e1–e19; June 10, 2021) Our paper, in part, focused on the role of tomato root xylem-enriched transcription factors in xylem development. Following publication of the article, we identified an error in the description of the literature. In Arabidopsis, high levels of miRNA-resistant PHABULOSA transcript result in protoxylem cells mis-specified as metaxylem (Miyashima et al., 2011). In the original version of the article, we incorrectly reversed the words “protoxylem” and “metaxylem.” Also, our data (Figure 3C, Figure S3) demonstrate ectopic protoxylem identity as a consequence of over-expression of tomato miRNA-resistant PHB/PHV-LIKE1 and not metaxylem identity, as observed in Arabidopsis by Miyashima et al., 2011. While our results are similar to reports of HD-ZIP III transcription factors regulating xylem development, they also illustrate conservation and repurposing of xylem patterning regulation between Arabidopsis and tomato. These changes do not affect the conclusions of the article, and the text has been corrected online. The authors apologize for any confusion this may have caused.
