During embryogenesis and crown root formation, QHB expression was observed prior to the morphological differentiation of the root.

在胚发育和冠状根形成过程中，QHB在根的形态分化之前就已经表达。

Using transformants carrying the QHB promoter-GUS and in situ hybridization, we found that QHB was specifically expressed in the central cells of a quiescent center (QC) of the root.

利用转化有QHB启动子驱动GUS报告基因的转基因植株和原位杂交，我们发现QHB在根静止中心的中央细胞内特异表达。
