The trebouxiophycean genus Phyllosiphon contains unique green algae that thrive as endophytic parasites in the leaves of various members of the Araceae. The DNA sequences of the parasitic populations were originally acquired from infected leaves of subtropical Arisarum vulgare. However, several previous studies showed that the members of the Phyllosiphon clade also occur as free-living algae on...

Arum species grow in temperate and Mediterranean climates have been used for hundreds of years food medicinal purposes, although they are highly toxic if not cooked using proper techniques. Glutathione reductase (GR) is a member the pyridine nucleotide disulfide oxidoreductase family flavoenzymes that catalyzes reduction glutathione (GSSG) to reduced GSH NADPH or NADH. In this study, GR enzyme ...

The subcellular location of two enzymes in the biosynthetic pathway for protoporphyrin IX, coproporphyrinogen (coprogen) oxidase (EC 1.3.3.3) and protoporphyrinogen (protogen) oxidase (EC 1.3.3.4) has been investigated in etiolated pea (Pisum sativum) leaves and spadices of cuckoo-pint (Arum maculatum). Plant tissue homogenized in isotonic buffer was subjected to subcellular fractionation to pr...
