Model for Embryonic Patterning of Auxin Biosynthesis, Transport, and Reception by the Ad/Abaxial Regulators REV and KAN.

(A) Summary of REV- and KAN-regulated auxin pathway genes. Arrow indicates direction of regulation. i = indirectly regulated. Data for direct regulation of TAA1 and YUC5 by REV is from Brandt et al. (2012) (1), Stepanova et al. (2008) (2), Friml et al. (2002) (3), Ploense et al. (2009) (4), and Hamman et al. (1999) (5).

(B) Location of KAN- and REV-regulated components of the auxin pathway during embryogenesis.
