Eudicot seed structure

Fig. 1. Diversity of eudicot seed structure and the presence of endosperm in mature seeds as widespread trait important for regulating germination.

Phylogenetic tree of the eudicots.
Seed structure of representative species for important eudicot clades.
Brassicaceae seeds as rosid representatives: b Lepidium sativum (garden cress), c Sisymbrium officinale (hedge mustard), d Arabidopsis thaliana (thale cress).
e-f Solanaceae seeds as asterid representatives: e Solanum lycopersicum (tomato), f Nicotiana tabacum (tobacco).
Beta vulgaris (sugarbeet, Amaranthaceae) as representative for the caryophyllids.
h Trollius spp. (globeflower, Ranunculaceae) as representative for the basal eudicots.
