Overexpression of Arabidopsis ATX1 retards plant growth under severe copper deficiency.

Plant signaling & behavior - 1 Sept 2012

Shin Lung-Jiun, Yeh Kuo-Chen

Abstract excerpt

In a previous study, we demonstrated that Arabidopsis Antioxidant Protein1 (ATX1) plays an essential role in copper (Cu) homeostasis, conferring tolerance to both excess and subclinically deficient Cu. The Cu-binding motif MXCXXC was required for the physiological function of ATX1. In this study, we found that overexpression of ATX1 resulted in hypersensitivity to severe Cu deficiency despite enhancing tolerance...
