... the Antirrhinum class B homeotic transcription factors DEFICIENS ( DEF ) and GLOBOSA ( GLO ) in the epidermis. Transgene expression was controlled by the ANTIRRHINUM FIDDLEHEAD ( AFI ) promoter, which directs gene expression to the L1 meristematic layer and, later, to the epidermis of differentiating organs...

...Marie-Christine Perbal; George Haughn; Heinz Saedler; Zsuzsanna Schwarz-Sommer ABSTRACT In Antirrhinum majus , petal and stamen organ identity is controlled by two MADS-box transcription factors, DEFICIENS and GLOBOSA. Mutations in either of these genes result in the replacement of petals...

...Sabine Zachgo; Eugenia de Andrade Silva; Patrick Motte; Wolfgang Tröbner; Heinz Saedler; Zsuzsanna Schwarz-Sommer ABSTRACT Flowers of the temperature-sensitive DEFICIENS ( DEF ) mutant, def -101, display sepaloid petals and carpelloid stamens when grown at 26°C, the non-permissive temperature...
