Abstract excerpt

To increase our understanding of the adaptation for copper (Cu) deficiency, Arabidopsis mutants with apparent alterations under Cu deficiency were identified. In this report, a novel mutant, tpst-2, was found to be more sensitive than wild-type (Col-0) plants to Cu deficiency during root elongation. The positional cloning of tpst-2 revealed that this gene encodes a tyrosylprotein sulfotransferase (TPST)....
