2 Figure 1 AG/WUS Feedback Loop in the Flower Meristem
(A) In the SAM, WUS acts in a feedback loop with CLV3 to maintain undifferentiated stem cells in the center of the meristem. (B) In floral meristems, the same feedback loop between WUS and CLV3 acts to maintain stem cells. LFY, which is expressed throughout the meristem, acts with WUS to activate transcription of AG in the central dome, which then feeds back to turn off WUS Developmental Cell 2001 1, 4-6DOI: ( /S (01) )
