Localization of the Site of Perception of Thermoinductive Temperatures in Thlaspi arvense L.
This paper describes attempts to localize the site of perception of low temperatures (0-10 degrees C) during thermoinduction in Thlaspi arvense L. Reproductive development (stem elongation and flower formation) was observed when shoots were cooled to 4 degrees C for 4 weeks and then returned to 21 degrees C while maintaining the roots constant 21 degrees C. However, chilling the roots was ineff...
متن کاملUniversal florigenic signals triggered by FT homologues regulate growth and flowering cycles in perennial day-neutral tomato.
The transition from vegetative to floral meristems in higher plants is programmed by the coincidence of internal and environmental signals. Classic grafting experiments have shown that leaves, in response to changing photoperiods, emit systemic signals, dubbed 'florigen', which induce flowering at the shoot apex. The florigen paradigm was conceived in photoperiod-sensitive plants: nevertheless ...
متن کاملdelayed flowering1 Encodes a basic leucine zipper protein that mediates floral inductive signals at the shoot apex in maize.
Separation of the life cycle of flowering plants into two distinct growth phases, vegetative and reproductive, is marked by the floral transition. The initial floral inductive signals are perceived in the leaves and transmitted to the shoot apex, where the vegetative shoot apical meristem is restructured into a reproductive meristem. In this study, we report cloning and characterization of the ...
متن کاملA common mechanism controls the life cycle and architecture of plants.
The overall aerial architecture of flowering plants depends on a group of meristematic cells in the shoot apex. We demonstrate that the Arabidopsis TERMINAL FLOWER 1 gene has a unified effect on the rate of progression of the shoot apex through different developmental phases. In transgenic Arabidopsis plants which ectopically express TERMINAL FLOWER 1, both the vegetative and reproductive phase...
متن کاملApical Meristems of Vegetative Shoots and Strobili in Certain Gymnosperms.
There has been considerable interest of late in the transition of seemingly vegetative shoots of angiosperms into "reproductive" axes with their appendages. The flowering shoot formed in this manner is assumed to be a reflection of a change or changes which must have taken place in the activity of the apical meristem. It is well known for certain angiosperms that a proper period of photoinducti...
