Advanced Science, EarlyView.Floral meristem (FM) activity is crucial for the initiation of floral organs. In this study, SE represses IPT7 expression and cytokinin signaling via both the miR171c‐5p–KNAT2 and miR164c–CUC1/2–KNAT2 regulatory modules, thereby repressing FM activity. In contrast, STM induces both KNAT2 and IPT7 expression.

Nature, 1881 SIR JOHN LUBBOCK'S address to the British Association, and Mr. Francis Darwin's paper in the Linnean Transactions, on the hygrometric awns of the achenes of Erodium and other plants, fail to give the honour to the right man. Their references reach some thirteen years back; but if they will look further they will find the late discoveries (including ...
