(Texas A&M University. Libraries, 1970)The lysine and protein content of corn seed was determined for inbred lines and crosses among inbred lines, to gain a better understanding of the genetic variation of these characters. Lysine content was determined by an ...
-
(Texas A&M University. Libraries, 1970)Triploid (3N) X translocation tester stock (2N) crosses were used to produce F₁ trisomics heterozygous for an interchange for associating the trisomes with the translocated chromosomes (temporarily assigned the letters A ...

(Texas A&M University. Libraries, 1968)
-
(Texas A&M University. Libraries, 1981)Two inheritance studies were conducted at College Station, Texas, to determine the nature and mode of inheritance of fermentable carbohydrates in stems of Sorghum bicolor (L.) Moench. Harvested stems were stripped and ...
-
(Texas A&M University. Libraries, 1980)Enzyme electrophoresis and multivariate morphometries were used to analyze hybridization between two species of wildrye, Elymus canadensis L. and E. virqinicus L. (Poaceae). A morphological cline correlated with longitude ...
-
(Texas A&M University. Libraries, 1972)The B₄ gene, the most effective gene for blight resistance in Upland cottons, was found to be closely linked with the P gene for yellow pollen color. The average percent crossing over of the test cross and F₂ was 4.45 which ...
-
(Texas A&M University, 1996)Portions of the mitochondrial DNA control region were used to determine the species of animal hair used in a 17th century merchant ship's hull sheathing for the purpose of deterring wood boring worms (Toredo navalis). DNA ...
-
(Texas A&M University. Libraries, 1968)Mitotic cells from root and leaf tips of seedlings treated with sodium fluoride at the concentration levels of 1x10⁻², 1x10⁻⁴, and 1x10⁻⁶ M were examined. Cytological analyses showed the occurrence of chromosomal gaps and ...
-
(Texas A&M University. Libraries, 1992)Ribulose bisphosphate carboxylase/oxygenase (rubisco, EC 4.1.1.39) catalyzes the first step in the Calvin pentose phosphate cycle. It is composed of eight large subunits and eight small subunits. The large subunits are ...
-
(Texas A&M University. Libraries, 1992)Sequences homologous to a 2.3 kilobase (kb) human HSP70 cDNA were extracted from a bovine sperm DNA library. The cloned DNA was restriction mapped and sequences containing HSP70 coding regions, along with those sequences ...
-
(Texas A&M University. Libraries, 1995)Most problems in molecular genetics reduce to searching for
-
(Texas A&M University. Libraries, 1969)Interchange monosomes, which have segments of two non-homologous chromosomes and hence form a chain of three chromosomes at MI of meiosis, are fertile and readily transmissible in Gossypium hirsutum. Tests for chromosome ...
-
(Texas A&M University. Libraries, 1995)The determination of the historical relationships among snakes and between snakes and other squamates has remained problematical due to the combined problems of morphological character homoplasies and polarity misinterpretations ...
-
(Texas A&M University. Libraries, 1994)Aspartate transcarbamoylase catalyses the first uniquely committed step of the de novo pyrimidine biosynthesis in Escherichia coli, the condensation of carbamoyl phosphate with aspartate. The genetic expression of the ...
-
(Texas A&M University. Libraries, 1991)Starch-gel electrophoresis of enzymatic proteins, restriction fragment length polymorphisms and random amplified polymorphic DNA w ere used to evaluate population structures of three species of Penaeid shrimp: Penaeus ...
-
(Texas A&M University. Libraries, 1977)ADPGlucose pyrophosphorylase A was purified 126-fold to homogeneity from maize endosperm. The molecular weight estimated by gel filtration was 375,000 and 400,000 by disc acrylamide electrophoretic techniques. SDS disc gel ...
-
(Texas A&M University. Libraries, 1993)Insects are likely to develop resistance to Bacillus thuringiensis spp. kurstaki CrylA insecticidal proteins expressed in cotton (Gossypium hirsutum L.) unless strategies are implemented to counter pest adaptation. Three ...
-
(Texas A&M University. Libraries, 1994)Abscisic acid (ABA) is required as a co-regulatory factor for all of the regulatory functions associated with Viviparous-1 (Vp1) during maize kernel development. The exception has been anthocyanin synthesis, because ...
-
(Texas A&M University. Libraries, 1989)Ultrastructural comparisons of aleurone tissues from wild type, vp/vp and vp5/vp5 maize kernels were made at 16, 25 and 35 days after pollination (DAP). Wild type and vp5 aleurone cells were similar at 16 and 25 DAP, but ...
-
(Texas A&M University. Libraries, 1979)In order to investigate changes in nucleotide metabolism during a developmental change in fungus Neurospora crassa, intracellular nucleotide pools were determined b high pressure liquid chromatography before and during ...
