Fig. 8From: Maize brachytic2 (br2) suppresses the elongation of lower internodes for excessive auxin accumulation in the intercalary meristem regionIn situ localization of BR2 mRNA in stem at the 10-leaf stage. a Longitudinal section of stem apex. The arrows represent each node in stem apex. Bar = 0.1 cm. b Longitudinal section of an intact internode. IN, internode; N, node. Bar = 0.3 cm. c Transverse section of longest internode. VB, vascular bundle. Bar = 0.2 cm. d, e Hybridization of a single internode with a BR2 sense probe for longitudinal section and transverse section, respectively. Bar = 0.2 cmBack to article page
