Abstract excerpt
Portulaca grandiflora, a member of the Centrospermae, produces the alkaloid-type betalain pigment in its petals and stems. Variegation patterns were observed on the corolla of some clones. The authors postulate that in Portulaca grandiflora a relation exist between unstable mutations and the pres...
