f9488a8cf8 Abaxial cell fate, which is likely to be the default state in the absence of the adaxial signal produced by the SAM (Bowman et al., 2002), is promoted by the YABBY andKANADI (Kerstetter et al., 2001) genes.YABBY gene expression is restricted to abaxial organ domains by the activity of PHB and related genes. Not as obvious to the eye are the lateral domains. The regular pattern of leaf initiation allows one to predict where the next leaf will appear. Lett. This report highlights and reviews some of what we know about the genetic circuitry that underlies leaf form, as discussed at a workshop on Leaf Development held February 11 through 13, 2002, at the Instituto Juan March (Madrid). Hirokazu Tsukaya (National Institute for Basic Biology, Okazaki, Japan) described his analysis of AS2 andBLADE-LIKE PETIOLE (BLP) two genes that are, in his view, involved in the positioning of the central and proximodistal leaf axes in Arabidopsis. It is interesting that later in development, their expression becomes restricted to the adaxial domain of the leaf, contrary to what happens in Arabidopsis. arXiv:cond-mat/0702335.

To fix this, set the correct time and date on your computer. These results, taken together with the demonstration that yabby genes are downstream oflbl1, indicate that the lbl1, rld1, and yabby genes are involved in dorsiventral patterning of the monocotyledonous maize leaf, whose polarity may be inverted relative to that of the dicotyledonous Arabidopsis leaf.

History. In each case, gene expression, normally excluded from simple leaves, was found expressed in species with dissected leaves and correlated with the dissected leaf shape. This tends to occur with a basal configuration.
