Influence of cobalt uptake by Vicia faba seeds on chlorophyll morphosis induction, SOD polymorphism, and DNA methylation.

Vicia faba plants show polymorphism to cobalt (Co) excess, expressed by a different degree of chlorophyll morphosis (CM)-from normally green (N) to yellow (Y) seedlings. For superoxide dismutase (SOD), the high V. faba polymorphism was revealed and increased by Co stress.
