13. Hidrolases e fenoloxidases de microrganismos como marcadores para seleção de biosuplementadores e avaliação do tratamento sobre efluentes sucroalcooleiros
Due to the current and future problematic of the maintenance of the hydric resources, the reuse of waters after previous treatment has been a strategy in the management of aquifers. The bioaugmentation is one of the techniques of purification of effluents and, because of this, studies were carried out in lagoons from the station of treatment of effluents (ST

14. Remediation of cadmium- and lead-contaminated soils with an aluminum industry by-product / Subproduto da indÃstria de alumÃnio na remediaÃÃo de Ãreas contaminadas com cÃdmio e chumbo
Mining activities have been increasing each day and generate large amounts of residues or by-products, which have caused a lot of interest by researchers in evaluating their potential use as soil amendments. One of the applications of such amendments is on the remediation of soils contaminated with trace elements, which might pose a threat to animals and pla

15. Expression in yeast of the T-urf13 protein from Texas male-sterile maize mitochondria confers sensitivity to methomyl and to Texas-cytoplasm-specific fungal toxins.
The mitochondrial gene T-urf13 from maize (Zea mays L.) with Texas male-sterile (T) cytoplasm codes for a unique 13 kd polypeptide, T-URF13, which is implicated in cytoplasmic male sterility and sensitivity to the insecticide methomyl and to host-specific fungal toxins produced by Helminthosporium maydis race T (HmT toxin) and Phyllosticta maydis (Pm toxin).

16. Phylogenetic Evidence for the Existence of Novel Thermophilic Bacteria in Hot Spring Sulfur-Turf Microbial Mats in Japan
So-called sulfur-turf microbial mats, which are macroscopic white filaments or bundles consisting of large sausage-shaped bacteria and elemental sulfur particles, occur in sulfide-containing hot springs in Japan. However, no thermophiles from sulfur-turf mats have yet been isolated as cultivable strains. This study was undertaken to determine the phylogeneti

17. A mitochondrial gene is lost via homologous recombination during reversion of CMS T maize to fertility
The Texas (T) male sterile cytoplasm of maize is distinguished by a mitochondrially synthesized 13-kd polypeptide and a high susceptibility to the toxin produced by the fungal pathogen Helminthosporium maydis. Fertile, toxin-resistant revertants show an altered restriction profile for mitochondrial DNA and do not produce the 13-kd polypeptide. Characterizati

18. Rf8 and Rf* Mediate Unique T-Urf13-Transcript Accumulation, Revealing a Conserved Motif Associated with RNA Processing and Restoration of Pollen Fertility in T-Cytoplasm Maize
Rf8 is a newly described nuclear gene that can substitute for Rf1 to partially restore pollen fertility to male-sterile, T-cytoplasm maize. Families segregating for Rf8 were used to investigate the mechanism of this fertility restoration and to compare it to the restoration conditioned by Rf1. Although Rf8 is unlinked to the rf1 locus, it also alters T-urf13

19. Targeting the maize T-urf13 product into tobacco mitochondria confers methomyl sensitivity to mitochondrial respiration.
The URF13 protein, which is encoded by the maize mitochondrial T-urf13 gene, is thought to be responsible for pathotoxin and methomyl sensitivity and male sterility. We have investigated whether T-urf13 confers toxin sensitivity and male sterility when expressed in another plant species. The coding sequence of T-urf13 was fused to a mitochondrial targeting p

20. Uptake and Assimilation of NO3− and NH4+ by Nitrogen-Deficient Perennial Ryegrass Turf
Assimilation of NO3− and NH4+ by perennial ryegrass (Lolium perenne L.) turf, previously deprived of N for 7 days, was examined. Nitrogen uptake rate was increased up to four- to five-fold for both forms of N by N-deprivation as compared to N-sufficient controls, with the deficiency-enhanced N absorption persisting through a 48 hour uptake period. Nitrate,

22. Mutator-Induced Mutations of the Rf1 Nuclear Fertility Restorer of T-Cytoplasm Maize Alter the Accumulation of T-Urf13 Mitochondrial Transcripts
Dominant alleles of the rf1 and rf2 nuclear-encoded fertility restorer genes are necessary for restoration of pollen fertility in T-cytoplasm maize. To further characterize fertility restoration mediated by the Rf1 allele, 123,500 gametes derived from plants carrying the Mutator transposable element family were screened for rf1-mutant alleles (rf1-m) Four he
