FT protein movement contributes to long-distance signaling in floral induction of Arabidopsis.
In plants, seasonal changes in day length are perceived in leaves, which initiate long-distance signaling that induces flowering at the shoot apex. The identity of the long-distance signal has yet to be determined. In Arabidopsis, activation of FLOWERING LOCUS T (FT) transcription in leaf vascular tissue (phloem) induces flowering. We found that FT messenger RNA is required only transiently in ...
متن کاملLong-distance Movement of a Pinniped Neonate
Understanding long-distance dispersal patterns for wide-ranging species is critical to developing effective conservation strategies (Lockwood et al. 2002, Shanks et al. 2003, Gerber et al. 2005, Figueira and Crowder 2006). California sea lions (Zalophus californianus) in the Gulf of California (GoC) are thought to include distinct populations based on limited dispersal and resulting genetic pop...
متن کاملLong-Distance Wh-Movement and Minimalism
1 Introduction Long wh-movement is a phenomenon by which an element appears to move directly from an A-or A-position to a higher A-destination, ignoring weak island constraints and bypassing the intermediate landing sites that are characteristic of successive-cyclic wh-movement. Cinque (1990) gives some examples of the contrast between long and successive-cyclic wh-movements, illustrating the l...
متن کاملSystemic movement of FT mRNA and a possible role in floral induction
FLOWERING LOCUS T (FT) protein is known to be part of the mobile flowering inducing "florigen" signal in plants, but it may not be acting alone. This article reviews the data that FT mRNA can also move systemically throughout the plant and into the shoot apical meristem (SAM) independently of the FT protein. There is a promotion of flowering when increased levels of virally expressed FT mRNA ar...
