Tributyltin pollution from antifouling paint is well known to disrupt the endocrine system in female marine gastropods. The masculinization of females, including the aberrant growth of a penis and vas deferens and occlusion of the capsule gland, has been reported primarily in neogastropods and is particularly well documented in muricids. Compared to temperate areas, few studies of imposex have ...

The nivea (niv) gene of Antirrhinum majus encodes chalcone synthase, an enzyme involved in synthesis of anthocyanin pigments. The nivfeC:98 allele contains a single copy of the transposon Tamd inserted at the niv locus. A large chromosomal rearrangement derived from this mutant has been shown to be flanked by two copies of Tam3. In this study, we compared sequences involved in this rearrangemen...

Phytoremediation is a promising technique for reducing mercury (Hg) pollution. Little known about the phytoremediation potential of ramie (Boehmeria nivea L. Gaud.) and response its rhizosphere soil microbiome to Hg contamination. In this study, we planted in three plots contaminated with different levels pollution evaluated accumulation translocation. We also analyzed abundance, composition, p...

Naturally occurring tufts of the mixotroph Thiothrix nivea blanketed the East Everglades (Dade County, Fla.) Chekika artesian well and runoff areas. The rate of HCO(3) fixation by these Thiothrix tufts was determined to be 14.0 +/- 5.4 nmol of HCO(3) per min per mg of dry weight, which reflected a growth rate of 5.0%/h. The addition of 10 mM glucose, ribose, acetate, or pyruvate or 0.05% Casami...
