(Texas A&M University. Libraries, 1984)Pyrimidine nucleotides may be provided for cellular growth via a de novo biosynthetic pathway or salvage pathways of interconversion of nucleosides and bases. The de novo biosynthesis in D. discoideum is provided by the ...
-
(Texas A&M University. Libraries, 1984)Increased utilization of novel biomass sources for energy conversion schemes has become a significant portion of energy related research and sorghum (Sorghum bicolor (L.) Moench) is often considered a viable potential ...
-
(2018-11-20)The mammalian circadian clock, found in virtually every cell, coordinates rhythmic expression to control the daily regulation of biological functions. These cell autonomous circadian clocks rely on a molecular feedback ...
-
(2022-07-26)Pecan (Carya illinoinensis) is an important tree nut species in the United States with average annual in-shell nut production value of $430 million in 2020 according to the NASS. The present research characterized a core ...
-
(Texas A&M University. Libraries, 1985)Inbred lines, F1 crosses and progeny from F2 populations were utilized to determine if the primary loci which control pericarp color (R, Y, B1, B2 and S) affected tannin presence and concentration differently when they ...
-
(Texas A&M University. Libraries, 1985)Small mammals of two species (Peromyscus leucopus and Sigmodon hispidus) were trapped at a locality polluted with a complex mixture of petrochemical waste products, heavy metals, and PCB's, and from two matched, uncontaminated ...
-
(Texas A&M University. Libraries, 1986)Karyotypic data from a total of 574 deer mice from insular populations off British Columbia and Washington indicate the presence of two distinct karyotypic groups, a "low FN" group (FN = 74-78) and a "high FN" group (FN = ...
-
(Texas A&M University. Libraries, 1984)Oryzomys melanotis comprises at least three chromosomal races: a 2n=62, FN=68 cytotype in eastern and southern Mexico; a 2n=64, FN=70 cytotype on the Yucatan Peninsula; and a 2n=60, FN=116 cytotype in western Mexico. ...

-
(Texas A&M University. Libraries, 1989)The genes for fibronectin, gamma crystallin and isocitrate dehydrogenase are syntenic in man, mouse and cow. In an effort to physically localize this conserved chromosomal region in the genomes of the respective species, ...
-
(Texas A&M University. Libraries, 1986)Parameters affecting couscous quality were evaluated. Considering sorghum and millets, significant differences were found for milling ability, product color and chemical analysis. Millet products exhibited a higher degree ...
-
(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, 1956)
-
(Texas A&M University. Libraries, 1984)Twelve plants were chosen from the progeny of a newly-acquired African accession of buffelgrass (accession 409674) for use as parents in a cytological study to characterize mode of reproduction. Using a cleared-carpel ...
-
(Texas A&M University. Libraries, 1982)Little bluestem (Schizachyrium scoparium (Michx.) Nash var. frequens F. T. Hubb) is a highly polymorphic perennial grass of North America. The studies described here deal with various effects of defoliation on little ...
-
(2015-05-01)In order to gain a better understanding of the effects and amount of recombination that can be available to future plant breeding endeavors, a unique mapping population was created. A di-hybrid maize (Zea mays L.) cross ...
-
(2022-07-07)The cotton genus, Gossypium, includes 52 species of which 45 are diploid and 7 are tetraploid. While G. hirsutum L. (2n=4x=52) is by far the most important agriculturally, all of the species are potential sources for ...
-
(Texas A&M University. Libraries, 1983)Three populations of tomato crosses from a pedigree breeding program were analyzed to determine the number of selections made among the segregating progenies of each cross in each generation during the life of the populations. ...
