13. Behavior of Santa Inês sheep of different colors of coat, grazing / Comportamento de ovinos da raça Santa Inês de diferentes cores pelame, em pastejo
The experiment was conducted during the summer in the Agreste region of Pernambuco state in order to evaluate the behavior under conditions of grazing sheep Santa Ines of different colors of coat. The experiment lasted from January 12 to 01 March 2008, with two and six weeks to adapt to data collection. The observations were made every 10 minutes during the

14. Índices de conforto térmico para ovinos Santa Inês de diferentes cores de pelame em condições de pastejo / Critical levels of thermal confort for Santa Inês sheep under grazing at Agreste Region at Pernambuco State
The objectives of this work were to determine the best physiological parameter indicator of thermal stress in Santa Inês sheeps, to verify coat color influence on tolerance to heat, to determine the most adequate thermal comfort index for these animals under grazing conditions, and to estimate the critical values of comfort index for short hair Santa Inês

15. Genetic basis of the resistance to Strongyloides venezuelensis (Nematoda, Rhabdiasidae) infection in mice (Mus musculus)
We investigated the resistance to Strongyloides venezuelensis primary infection of mice strains NIH (resistant) and C57BL/6 (susceptible) and the F1 and F2 offspring of crosses between these strains. The mice were infected with 2000 larvae and seven days later were sacrificed for parasite recovery and counting. There was no statistically significant (p > 0.0

16. Recobrimento de sementes de cenoura com aglomerante em diversas proporções e fungicida
O objetivo do trabalho foi avaliar a qualidade fisiológica de sementes de cenoura após o recobrimento com aglomerante (vermiculita) nas proporções 2:1 e 3:1 e a adição do fungicida Thiram + Carbendazin. Também foram utilizados adesivo (acetato de polivinil) e corante "color coat". A qualidade fisiológica das sementes de cenoura (Daucus carota L.), cv

17. MICROMORFOLOGÍA Y ESTRUCTURA DE LA CUBIERTA SEMINAL DE CUATRO ESPECIES DE LOASACEAE JUSS. PRESENTES EN VENEZUELA
ABSTRACT Was carried out the morphological and anatomical study of the seed coat of Gronovia scandens L., Klaprothia fasciculata (Presl.) Poston & Nowicke, Mentzelia aspera L., and Nasa triphylla (Juss.) Weigend, species belonging to the Loasaceae. The study was carried out with fresh material fresh and herbarium material.

19. Interaction of the Murine Dilute Suppressor Gene (Dsu) with Fourteen Coat Color Mutations
The murine dilute suppressor gene, dsu, was previously shown to suppress the dilute coat color phenotypes of mice homozygous for the dilute (d), leaden (ln), and ashen (ash) mutations. Each of these mutations produce adendritic melanocytes, which results in an abnormal transportation of pigment granules into the hair shaft and a diluted coat color. The suppr

20. The mouse mahoganoid coat color mutation disrupts a novel C3HC4 RING domain protein
The mouse coat color mutant mahoganoid (md) darkens coat color and decreases the obesity of Ay mice that ectopically overexpress agouti-signaling protein. The phenotypic effects of md are similar to those of the recently identified coat color mutant mahogany (Atrnmg). We report the positional cloning of mahoganoid, encoding a novel 494–amino acid protein c

21. Clonal coat color variation due to a transforming gene expressed in melanocytes of transgenic mice.
Transgenic mice of an inbred black strain were previously produced with the Tyr-SV40E transgene, comprising simian virus 40 transforming sequences driven by the tyrosinase promoter, in order to obtain melanomas; the animals were found to be lighter than normal in coat color, to various degrees. As described here, hypopigmentation resulted from diminished dif

22. Molecular Markers for the agouti Coat Color Locus of the Mouse
The agouti (a) coat color locus of the mouse acts within the microenvironment of the hair follicle to control the relative amount and distribution of yellow and black pigment in the coat hairs. Over 18 different mutations with complex dominance relationships have been described at this locus. The lethal yellow (Ay) mutation is the top dominant of this series

23. The Murine Dilute Suppressor Gene Dsu Suppresses the Coat-Color Phenotype of Three Pigment Mutations That Alter Melanocyte Morphology, D, Ash and Ln
The murine dilute suppressor gene, dsu, was identified because of its ability to suppress the dilute coat color of mice homozygous for the retrovirally induced allele (d(v)) of the dilute locus (d). dsu is unlinked to the d locus and has recently been shown to be semidominantly inherited. The dilute phenotype of d/d mice is the consequence of abnormal melano

24. Coupled Site-Directed Mutagenesis/Transgenesis Identifies Important Functional Domains of the Mouse Agouti Protein
The agouti locus encodes a novel paracrine signaling molecule containing a signal sequence, an N-linked glycosylation site, a central lysine-rich basic domain, and a C-terminal tail containing 10 cysteine (Cys) residues capable of forming five disulfide bonds. When overexpressed, agouti causes a number of pleiotropic effects including yellow coat and adult-o
