... mutant phenotype, such that ap1 cal double mutants proliferate inflorescence meristems in positions that would normally be occupied by flowers, resulting in a ‘cauliflower’ appearance. Eventually, however, flower meristems are specified and ap1 -like flowers are produced ( Bowman et al., 1993...

.... PFG is expressed in the entire plant except stamens, roots and seedlings. Highest expression levels of PFG are found in vegetative and inflorescence meristems. Inhibition of PFG expression in transgenic plants, using a cosuppression strategy, resulted in a unique nonflowering phenotype. Homozygous pfg...

... FLOWER 1 ( TFL1 ) Inflorescence meristem LEAFY ( LFY ) APETALA 1 ( AP1 ) Flower development The life cycle of most organisms can be divided into several developmental phases, from an early juvenile period when resources are built up, through to a reproductive phase ( Poethig, 1990...

...Erik Souer; Alexander van der Krol; Daisy Kloos; Cornelis Spelt; Mattijs Bliek; Jos Mol; Ronald Koes ABSTRACT A main determinant of inflorescence architecture is the site where floral meristems are initiated. We show that in wild-type Petunia bifurcation of the inflorescence meristem yields two...
