It has herbicidal properties killing young seedlings of both monocot and dicot species. It also inhibits the growth of the seedlings of both monocot and dicot plants. Phylogenetic analysis indicates that the monocots are a development from a dicot ancestor. In addition, some monocots have dicot characteristics such as reticulated leaf veins. They are mainly found in dicot plants except the family Liliaceae which are monocots. Despite this, only three families of monocots use carbon fixation compared to 15 dicot families. It is a herbaceous, perennial dicot native to eastern and central Canada and United States. "Artemisia douglasiana" is dicot, and a perennial forb. However, no xylan synthase complexes have been isolated from "Arabidopsis" tissues (dicot). It has a similar root and stem system to others in the dicot family "Asteraceae". Of the dicot clades containing species, the order Caryophyllales contains the most species. It is actually not a grass, but an herbaceous dicot. Few dicot shrubs with multiple branching and secondary growth species have been described. African nightshade is an erect dicot with many branches, growing 0.5 to 1.0 m high. It causes high levels of gene expression in dicot plants.
