1. Effect of both host plant and mating disruption technique on the reproductive behavior of Leucopteta coffeella (Lepidoptera: Lyonetiidae) / Efeito da planta hospedeira e da técnica da confusão sexual no comportamento reprodutivo de Leucoptera coffeella (Lepidoptera: Lyonetiidae)
The present thesis had the aim to study the importance of the host plant to the reproductive behavior of L. coffeella. At first, the following aspects were evaluated: (i) the effect of the reproductive condition of females in response to host plant volatiles; (ii) if mating proportion, initiation time and copulation duration are affected by the presence of v

2. Initial studies of mating disruption of the tomato moth, Tuta absoluta (Lepidoptera: Gelechiidae) using synthetic sex pheromone
O potencial do componente principal sintético do feromônio sexual de T. absoluta (Meyrick) para a interrupção dos acasalamentos foi estudado em parcelas (0,01 hectares) cultivadas com tomate estaqueado. Os efeitos de doses do 3E,8Z,11Z-14:Ac (0 a 80 g i.a./ha) aplicadas nas parcelas foram determinados considerando a orientação dos machos às armadilhas

3. Schizosaccharomyces pombe zfs1+ encoding a zinc-finger protein functions in the mating pheromone recognition pathway.
We isolated the Schizosaccharomyces pombe zfs1 gene as a multicopy suppressor of the sterility caused by overexpression of a double-stranded RNase. The deduced zfs1 gene product of 404 amino acids showed similarity to a mouse growth factor-inducible nuclear protein Nup475. Its C-terminal region carried two putative zinc-fingers, both of which should be intac

4. The KlGpa1 Gene Encodes a G-Protein α Subunit That Is a Positive Control Element in the Mating Pathway of the Budding Yeast Kluyveromyces lactis
The cloning of the gene encoding the KlGpa1p subunit was achieved by standard PCR techniques and by screening a Kluyveromyces lactis genomic library using the PCR product as a probe. The full-length open reading frame spans 1,344 nucleotides including the stop codon. The deduced primary structure of the protein (447 amino acid residues) strongly resembles th

5. New Potential Cell Wall Glucanases of Saccharomyces cerevisiae and Their Involvement in Mating
Biotinylation of intact Saccharomyces cerevisiae cells with a nonpermeant reagent (Sulfo-NHS-LC-Biotin) allowed the identification of seven cell wall proteins that were released from intact cells by dithiothreitol (DTT). By N-terminal sequencing, three of these proteins were identified as the known proteins β-exoglucanase 1 (Exg1p), β-endoglucanase (Bgl2p)

6. Somatic pairing of homologs in budding yeast: existence and modulation
FISH analysis of well-spread chromosomes reveals that homologs are paired in vegetatively growing budding yeast diploid cells, via multiple interstitial interactions, and independent of recA homologs and mating type heterozygosity. Pairing is present during G1 and G2, and in cells arrested at G1 by mating pheromone, but is disrupted during S phase. Thus, som

7. Mutations in a gene encoding the alpha subunit of a Saccharomyces cerevisiae G protein indicate a role in mating pheromone signaling.
Mutations which allowed conjugation by Saccharomyces cerevisiae cells lacking a mating pheromone receptor gene were selected. One of the genes defined by such mutations was isolated from a yeast genomic library by complementation of a temperature-sensitive mutation and is identical to the gene GPA1 (also known as SCG1), recently shown to be highly homologous

8. The Fission Yeast Ubiquitin-Conjugating Enzymes UbcP3, Ubc15, and Rhp6 Affect Transcriptional Silencing of the Mating-Type Region
Genes transcribed by RNA polymerase II are silenced when introduced near the mat2 or mat3 mating-type loci of the fission yeast Schizosaccharomyces pombe. Silencing is mediated by a number of gene products and cis-acting elements. We report here the finding of novel trans-acting factors identified in a screen for high-copy-number disruptors of silencing. Exp

9. Schizosaccharomyces pombe sxa1+ and sxa2+ encode putative proteases involved in the mating response.
The Schizosaccharomyces pombe sxa1 and sxa2 mutants showed an exaggerated response to mating pheromones, producing excessively long conjugation tubes and exhibiting mating deficiency. This phenotype was similar to phenotypes of cells bearing an activated allele of ras1, such as ras1Val-17 or ras1Leu-66, and phenotypes of cells defective in gap1. However, gen

10. Deletion of the Schizophyllum Commune Aα Locus: The Roles of Aα Y and Z Mating-Type Genes
The Aα locus is one of four master regulatory loci that determine mating type and regulate sexual development in Schizophyllum commune. We have made a plasmid containing a URA1 gene disruption of the Aα Y1 gene. Y1 is the sole Aα gene in Aα1 strains. We used the plasmid construction to produce an Aα null (i.e., AαΔ) strain by replacing the genomic Y1

11. Isolation and characterization of a gene encoding a G-protein alpha subunit from Schizosaccharomyces pombe: involvement in mating and sporulation pathways.
The gpal gene of Schizosaccharomyces pombe, which encodes a protein homologous with the alpha subunits of mammalian guanine nucleotide-binding proteins (G proteins), was isolated by cross-hybridization using rat Gi1 alpha and Gx alpha cDNA. The deduced amino acid sequence was about 37% identical with rat Gi1 alpha and Gx alpha proteins and contained three co

12. Mutations in the Myp1 Gene of Ustilago Maydis Attenuate Mycelial Growth and Virulence
Mating between haploid, budding cells of the dimorphic fungus Ustilago maydis results in the formation of a dikaryotic, filamentous cell type. Mating compatibility is governed by two mating-type loci called a and b; transformation of genes from these loci (e.g., a1 and b1) into a haploid strain of different mating type (e.g., a2 b2) allows filamentous growth
