(Texas A&M University. Libraries, 1974)Synthetic and exonucleoplytic activity of DNA polymerase II was examined in a mutT1 E. coli strain in an attempt to determine whether or not polB and mutT1 are allelic, a possibility suggested by the recent demonstration ...
-
(Texas A&M University. Libraries, 1995)A bacterial artificial chromosome (BAC) library has been constructed for use in bovine genome mapping using the pBeloBAC II vector. Currently, the library consists of 23,040 clones which achieves a 70% probability (P=0.70) ...
-
(Texas A&M University. Libraries, 1992)A mutation in a coat color gene in mice provides an opportunity to study the genetics and physiology of pigmentation, which is a powerful tool for understanding many biological processes, especially development. In 1989, ...
-
(Texas A&M University. Libraries, 1988)Attempts to define the antibody response to Brucella abortus vaccination and challenge have been contradictory in assessing the relative importance of specific isotypes and their expression in resistant and susceptible ...
-
(Texas A&M University. Libraries, 1990)Bovine genomic IGL and IGHM probes were used to map these immunoglobulin genes to bovine syntenic group U23 and BTA21 using bovine-hamster hybrid somatic cells. These cells segregate bovine chromosomes while retaining a ...
-
(Texas A&M University. Libraries, 1974)Using computer simulation, two methods for isolating inbred lines by repeated selfing were compared on the basis of the performance of derived inbreds in crosses to an array of homozygous testers. The simulation results ...
-
(Texas A&M University. Libraries, 1967)
-
(Texas A&M University. Libraries, 1987)Chromosomal NOR banding was used to assay the variability of chromosomal NORs within and among 49 species (380 specimens) of North American Cyprinidae. Considerable intra- and interspecific NOR variability was documented. ...
-
(Texas A&M University. Libraries, 1990)DNA content of Meloidogyne-induced giant cell nuclei in several host species was measured microspectrophotometrically. Nuclei from mature giant cells in pea and tomato averaged over a 14-fold increase in DNA compared to ...
-
(Texas A&M University. Libraries, 1968)The primary object of this study was to determine some of the difference at the chromosome level between the two tetraploid species, G. hirsutum and G. barbadense, which cross readily and the F₁ hybrid is fertile but the ...
-
Cytotaxonomic relationships in the genera Pennisetum and Cenchrus and the manipulation of apomixis (Texas A&M University. Libraries, 1971)The cytotaxonomic relationships of buffelgrass and birdwoodgrass were investigated to provide information for taxonomic classification and as a basis for a breeding program with these species. The relationship of these ...
-
(Texas A&M University. Libraries, 1988)Sectors of Zea mays cobs, with and without kernels were cultured in vitro in the presence and absence of fluridone. Kernel sections cultured in the presence of fluridone were transferred to medium containing fluridone and ...
-
(Texas A&M University. Libraries, 1973)Two families each of wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), corn (Zea mays L.), and bean (Phaseolus vulgaris L.) were studied for mitochondrial heterosis, in vitro complementation, and presence of ...
-
(Texas A&M University. Libraries, 1970)This study was undertaken to evaluate the discriminating power of gamete selection in the Sq generation and to determine the extent to which combining ability of So genotypes of corn, estimated by the gamete selection ...
-
(Texas A&M University. Libraries, 1993)The genetics of the mitochondrial cytochrome c oxidase subunit II (COII) gene was examined in an array of primates, rodents and representatives of other orders of placental mammals. Among primates these phylogenetic ...
-
(Texas A&M University. Libraries, 1993)Experiments were designed to understand the genetic and ontogenic characteristics of resistance to Colletotrichum graminicola (Ces.) Wils. in Sorghum bicolor (L.) Moench. Resistant lines SC326-6 and SC599-11E were crossed ...
-
(Texas A&M University. Libraries, 1995)The time and mode of gene expression of the Semigamy mutant was examined by developing a genetical-statistical analysis based on a novel application of joint-scaling tests. A 3x3 factorial mating of genetically-marked ...
-
(Texas A&M University. Libraries, 1990)The fertility of a first generation male hybrid deer produced from a cross between a male Odocoileus virginianus (white-tailed deer) and a female O. hemionus (mule deer) was assessed. Examination of mitotic chromosomes and ...
-
(Texas A&M University. Libraries, 1972)A study was made of three enzymes, leucine aminopeptidase, alcohol dehydrogenase, and peroxidase in dry loblolly pine (Pinus taeda L.) seed. Two 10 tree modified half diallels in two separate wild strands were used as seed ...
-
(Texas A&M University. Libraries, 1985)Metabolic resistance (R) controlled by a major gene on chromosome II in house flies is maintained in a heterozygous (R/S) condition in a laboratory strain called R-Propoxur-car. After 120 generations of intermittent selection ...
