Leaf Evolutionary Developmental Genetics in Pitcher Plants.

The evolution of carnivorous plants involves spectacular changes in form and function of the leaf. Significantly, the carnivorous pitcher form evolved independently three times in angiosperms. The three distantly related pitcher families, Cephalotaceae, Nepenthaceae, and Sarraceniaceae, all have pitchers with the inside of the ascidium corresponding to the former adaxial side of a normal bifacial leaf and the outside of the pitcher corresponding to the former abaxial side. The genetic model of bifacial leaf development provides hypotheses of possible genetic changes associated with pitcher development and evolution. We address these hypotheses using genes isolated from the Western Australian pitcher plant, Cephalotus folicularis. Members of the YABBY and HD-ZIP Class III gene families were isolated using degenerate primers designed from Arabidopsis thaliana and data from the transcriptome sequencing project 1KP. The pattern of expression of these leaves was then examined using in situ hybridization.
