... blade. We show that the growth and asymmetry of leaves in Antirrhinum majus involves the related YABBY transcription factors GRAMINIFOLIA (GRAM) and PROLONGATA (PROL). GRAM is expressed in abaxial margins of organ primordia where it promotes lateral growth and abaxial cell fate. GRAM , however...

...Richard Waites; Andrew Hudson ABSTRACT To understand better the mechanisms that lead to dorsoventrality in the lateral organs of plants, mutants at the phantastica ( phan ) locus of Antirrhinum majus have been identified and characterised. The leaves, bracts and petal lobes of phan mutants show...

...Sabine S. Hantke; Rosemary Carpenter; Enrico S. Coen ABSTRACT We show that the flowering sectors on plants mutant for floricaula ( flo ), a meristem identity gene in Antirrhinum majus , are periclinal chimeras expressing flo in either the L1, L2 or L3 cell layer. Flower morphology is almost normal...
