MEM1 Evolution in the Genus Flaveria.

(A) Phylogenetic tree of the ppcA, ppcB, and ppcC PEPC promoter sequences of Flaveria. The sequence alignment was constructed with Dialign (Morgenstern et al., 1998) and corrected by hand. The tree was generated by the distance method as implemented in PAUP 4.0b10 (Swofford, 2002), where uninformative characteristics were excluded. Bootstrap analysis was performed with 1000 replications, and the obtained bootstrap values are indicated.

(B) Model of MEM1 evolution in the genus Flaveria. The model relies on the phylogeny of the genus Flaveria, which is based on morphological and molecular data sets (McKown et al., 2005).
