Regulation and Identity of Florigen: Flowering Locus T Moves Center Stage [PDF]
, 2008 The transition from vegetative to reproductive growth is controlled by day length in many plant species. Day length is perceived in leaves and induces a systemic signal, called florigen, that moves through the phloem to the shoot apex.

Buck Inverter without Shoot through
IET Power Electronics, 2017 A new buck inverter without shoot‐through problem is presented and analysed in this study. The traditional dual‐buck inverter has been proposed to solve the shoot‐through problem of bridge‐type inverters, eliminate the dead‐time effect and improve the reliability along with the conversion efficiency. However, the existing dual‐buck inverter is prone to

WIND1 Promotes Shoot Regeneration through Transcriptional Activation of ENHANCER OF SHOOT REGENERATION1 in Arabidopsis [PDF]
The Plant Cell, 2016 Many plant species display remarkable developmental plasticity and regenerate new organs after injury. Local signals produced by wounding are thought to trigger organ regeneration but molecular mechanisms underlying this control remain largely unknown. We previously identified an AP2/ERF transcription factor WOUND INDUCED DEDIFFERENTIATION1 (WIND1) as ...
