Extended Data Fig. 9. Comparisons of paralogous WOX3 protein sequences and WOX3 expression levels.

a, Amino acid alignment of the four maize WOX3 proteins. Amino acids that are conserved in at least two sequences are displayed in colour and protein domains are indicated. Alignment was performed using Geneious alignment software (Genious alignment). b, Mean normalized expression of WOX3 genes in the single-cell RNA-Seq dataset. Statistical significance was determined using a two-tailed Student’s t-test, *P < 0.01. Error bars, s.d. (n = 2).
