The FRO2 ferric reductase is required for glycine betaine's effect on chilling tolerance in Arabidopsis roots.

Physiologia plantarum - 1 Oct 2008

Einset John, Winge Per, Bones Atle M, Connolly Erin L

Abstract excerpt

FRO2 (At1g01580) codes for an NADPH-dependent ferric reductase in plasma membranes of root epidermal cells with a demonstrated role in iron uptake by plants. Ferric reductase activity has been shown to be the rate-limiting step for iron uptake in strategy I plants like Arabidopsis and in rice, but it has been unclear whether FRO genes have other physiological functions. We hypothesized that FRO2 was involved in...
