Isolation of Amatoxin-Resistant Lines of Chlamydomonas reinhardtii: Evidence for RNA Polymerase Mutants.

abstract：:A number of environmental stresses can lead to enhanced production of superoxide within plant tissues, and plants are believed to rely on the enzyme superoxide dismutase (SOD) to detoxify this reactive oxygen species. We have identified seven cDNAs and genes for SOD in Arabidopsis. These consist of three CuZnSODs (CSD...
