Molecular Phylogenetic Evidence For An Extracellular Cu Zn Superoxide Dismutase Gene In Insects, Joel D. Parker

Representatives of three ancient gene families of the antioxidant enzyme superoxide dismutase (SOD) can be found in most metazoans. In mammals and Caenorhabditis elegans , there is at least one gene each of the cytoplasmic, mitochondrial and extracellular lineages of SOD genes. The cytoplasmic SOD was one of the first enzymes to be implicated in ageing due to its protection against damaging oxygen free radicals. In contrast to other metazoans, insects were thought to lack a gene for the extracellular SOD. We have cloned and sequenced an SOD mRNA in the ant Lasius niger that appears to belong to this …

Willa Cather loved the Southwest. The landscapes and cu ltural history of the area held a prominent place in both her fiction and in her own creative consciousness.1 As Judith Fryer points out, after Cather visited New Mexico and Arizona in 1912, she became so enamored with the region that she returned many times over the fol lowing decade (41). During this period Cather published a novel heavily inspired by her affection for the Southwestern landscape-The Song of the Lark. This novel fol lows Thea Kronborg from her childhood in the fictional rural town of Moonstone, Colorado, through an artistic …
