Cell-cell signaling and movement by the floral transcription factors LEAFY and APETALA1.

Science (New York, N.Y.) - 4 Aug 2000

Sessions A, Yanofsky M F, Weigel D

Abstract excerpt

LEAFY (LFY) and APETALA1 (AP1) encode unrelated transcription factors that activate overlapping sets of homeotic genes in Arabidopsis flowers. Sector analysis and targeted expression in transgenic plants were used to study whether LFY and AP1 can participate in cell-cell signaling between and within different layers of the floral meristem. LFY signaled equally well from all layers and had substantial long-range...
