Phylogeny of the genus Lepidium, the distribution of the DOG1 gene, and infructescence morphology of L. sativum and L. papillosum. A, Distribution of DOG1 homologs in representatives of all major lineages, subclades, and geographic ranges of Lepidium spp. Shown is the Bayesian 50% majority rule consensus tree based on ITS sequence analysis, with mean posterior probability values (clade credibilities) below branches. Phylogeny was redrawn from Mummenhoff et al. (2009). For DOG1 gene sequences, see Supplemental Table S1. AF, Africa; AM, America; AUS, Australia and New Zealand; EA, Eurasia; PA, Pacific Islands (Hawaii). B to E, Comparison of infructescences and seeds of L. sativum and L. papillosum. Within the well-ordered infructescences of L. papillosum, the seed maturation gradient is accompanied by primary dormancy induction.
