摘要

Arsenic is much contained in the environment and is toxic for organisms. Some organisms are harboring the arsenate resistance. The resistance to arsenicals is mediated by the expression of arsenite efflux [Silver et al., 1993] or methylation of arsenic [Kaise et al., 1988]. Arsenate is taken up through Pi transport system in many organisms. It was reported that arsenate tolerant strain of higher plant Holcus lanatus showed low activities of arsenate uptake and Pi uptake [Meharg et al., 1992]. We generated arsenate-resistant and sensitive mutants by the tagging method of Chlamydomonas [Fujiwara et al., 2000]. Here we show characteristics of arsenate uptake and report that one of the arsenate-resistant mutants, AR3, enhances the activity of Pi uptake
