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。

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.

简而言之，这个中心支柱就像一个巨大而静止的钟摆。

In short, the shinbashira was acting like an enormous stationary pendulum.
