Preferential expression of ZmRAP2.7 in nodes initiated brace roots and upregulation in Corngrass1 mutant. (A) Relative expression levels of ZmRAP2.7 in root (R), nodes with brace roots (NBR), and nodes without brace roots (N) in field-grown wild-type plants at flowering stage. Bars indicate mean (±SD) (n = 3). Significant difference was indicated by different letters according to Tukey’s test. (B) Relative expression levels of ZmRAP2.7 in nodes of field-grown Corngrass1 mutant and wild-type plants at flowering stage. Bars indicate mean (±SD) (n = 3). Significant difference was indicated by an asterisk (**p < 0.01) according to Student’s t-tests.
