In equatorial and tropical regions, supergene mineral deposits created during water/rock interactions are found. Simply put, these formed through the accumulation of low solubility ions or preservation primary minerals. The manganese (Mn) examples economic importance associated with chemical weathering processes. Brazil, Southern Brasilia Orogen (SBO) was generated collision between Paranapanem...

The major histocompatibility complex (MHC) is a group of closely linked loci present in remarkably similar form in all mammals and perhaps in all vertebrates. It plays a still imperfectly understood but clearly important role in immune phenomena. Because of the unusual concentration of similar genes, I referred to it in 1968 as a supergene (1). Bodmer (2) has gone me one better, calling it a su...

Abstract. Interpreting the ages of supergene mineralogical phases in laterite is complex because they consist polycrystalline mixtures different at microscopic scale that could be crystalized epochs. Among geochronometers, (U-Th)/He method on hematite and goethite more often used, but can difficult to interpret due mixing. To resolve this issue, study proposes a methodology for performing detai...

Identifying how genes and their functions evolve after duplication is central to understanding gene family radiation. In this study, we systematically examined the functional diversification of the glutathione S-transferase (GST) gene family in Populus trichocarpa by integrating phylogeny, expression, substrate specificity, and enzyme kinetic data. GSTs are ubiquitous proteins in plants that pl...
