The core region of Phg2 is implicated in the control of development initiation. (A) Schematic structure of the Phg2 protein and of two deletion mutants. (B) The ability of phg2 mutant cells expressing wild-type or mutated versions of Phg2 to initiate multicellular development was assessed as described in Figure 2. Although high levels of Phg2 were detected in cells complemented with Phg2-K and Phg2-core (unpublished data), the initiation of development remained abnormal.
