Effects of ultraviolet-B radiation on plant growth, symbiotic function and concentration of metabolites in legumes and an assessment of F1 generation for carryover effects
Reduction in ozone layer thickness in the stratosphere and the resultant increase in ground level of biologically active ultraviolet-B (UV-B) radiation prompted research into the effect of UV-B on growth and metabolism of terrestrial plants. In this study, eight legume species including three …

Inheritance of Resistance to Fusarium Ear Rot and Fumonisin Accumulation in Corn
… of resistance. The inbred TBA76125 and the F1 generation were low for both fumonisin concentration and Fusarium ear rot. The inbreds CG1, CQ201 and GE440 all had higher fumonisin concentrations and Fusarium ear rot than TBA76125. The F1 generation from CG1, CQ201 and GE440 all had similar …

Soziale Belastung während der Trächtigkeit bei Long-Evans Laborratten (Rattus norvegicus) und ihre Effekte auf die Reproduktion sowie die Physiologie, das Verhalten und die Reproduktion ihrer Nachkommen
… Laborratten auf die Reproduktion der Parentalgeneration (F0-Weibchen) selbst, sowie auf die Reproduktion, das Verhalten und die Physiologie ihrer pränatal gestressten Nachkommen (F1-Generation) auswirkt (pränataler Stress). Hierbei galt das Hauptaugenmerk der Untersuchung dem Einfluss …

The transgenerational effects of Di(2-ethylhexyl) phthalate on female reproduction in mice
… thus, posing as a potential toxicant for several generations. Multiple organs are required to facilitate healthy reproduction. Organs within the hypothalamic-pituitary-ovary axis consist of the hypothalamus, anterior pituitary, and the ovary and are vulnerable to toxicant exposure. Specifically, …

Comparison of two different media and assisted hatching techniques on the embryo hatching rate using the mouse as a model
… the effect of two in vitro culture media ((Ham’s F10 and Tissue Culture Medium 199 (TCM-199)) and four assisted hatching techniques (mechanical, chemical, enzymatic and laser) on blastocyst formation and hatching rate using murine embryos as a model. The C57BL/6 and BALB/c mouse breeds were bred …

The effects of environmental nickel toxicity upon survival, growth, reproduction, fecundity, and lifespan of nematodes Caenorhabditis elegans, Pristionchus pacificus, and Caenorhabditis briggsae
… bound in sediment is highly lethal to the P0 generation of nematodes; however, the effects of nickel bound in sediment were not readily apparent on the F1 generation of both C. elegans and P. pacificus. Using liquid assays, we also determined that aqueous nickel was not detrimental to the P0 …

Secondary Traumatic Stress Promotes Central Sensitization of the Trigeminal System
… Dawley (receiver) rats and their offspring. The F1 generation of receiver rats showed elevated levels of eleven proteins, implicated in the development of central sensitization, in the spinal trigeminal nucleus in response to secondary traumatic stress. In conclusion, my findings provide evidence …

Effects of gestational heat stress on the lactational performance of gilts and growth performance and carcass characteristics of second-generation offspring
… the lactational performance of affected gilts (F1 generation), and 2) determine whether these effects of gHS are also evident in the next generation (F2 generation). Twenty-four gilts were bred and exposed to thermoneutral or heat stressed conditions for the entirety of gestation, and F1 female …

Prenatal exposure to phthalates accelerates reproductive aging in multiple generations of female mice
… have been observed in a multiple and transgenerational manner in female mice. Recent studies have also shown that phthalates may accelerate reproductive aging. Reproductive aging in females is characterized by biomarkers including a drastic decrease in the ovarian follicle pool, …

Identification Of Candidate Genes For Self-Compatibility In A Diploid Population Of Potato Derived From Parents Used In Genome Sequencing
… in diploid potato. Within a population of F1 hybrids between two genotypes used in potato genome sequencing, we observed fruit set on many greenhouse-grown plants. Subsequently, after controlled self-pollinations, we confirmed fruit set in 32 of 103 F1 plants. Our goal was to identify genes …

Charakterisierung von Stereotypien bei der FVB/NJ-Maus hinsichtlich metabolischer und immunologischer Aspekte auf die Stoffwechselleistung
… der mütterlichen Fürsorge in der Parentalgeneration. Insgesamt wurden 35 Jungtiere der F1-Generation vom Absatz an, über einen Zeitraum von 11 Wochen einzeln gehalten, kontinuierlich beobachtet, bis zum Versuchsende wöchentlich Kotproben gesammelt und das Körpergewicht bestimmt. Zusätzlich …

Investigating the Effects of Vinclozolin on Reproduction in Three Generations of Sigmodon Hispidus
… a control group that drank distilled water. Each generation bred with non-littermates within the same treatment. The P's gave rise to the F1 generation, which bred to produce the F2 generation. Comparisons were made between generations (as the P was exposed to treatment only upon weaning, whereas …

Effect of different culture media and incubation methods on culturing murine embryos in vitro using a semen straw as an alternative receptacle
… in vitro embryo development in TCM-199 and Ham's F10 culture media until the blastocyst formation. The spermatozoa and oocytes of an F1 generation (Balb C x C57) were fertilized in Ham's F10 and TCM-199 in semen straws and in micro-drops in petri dishes. The embryos were cultured in TCM-199 and …

Prenatal exposure to di-(2-ethylhexyl) phthalate and high-fat diet synergistically disrupts mouse fetal oogenesis and affects folliculogenesis
… spreads. At 8 days postpartum (dpp) and 21 dpp, F1 ovaries were harvested and subjected to histological evaluation. We found that treatment with an environmentally relevant dosage of DEHP and consumption of high-fat diet relevant to a western diet significantly increases synapsis defects in …

Diet- and Probiotic-mediated Modulation of the Maternal Gut Microbiome Impacts Early-life Programming of Neurodevelopment and Behavioral Outcomes in Offspring
… synaptic plasticity deficits in male offspring (F1). For this thesis, we investigated whether MHFD similarly induces dysbiosis in female offspring (F1), which we hypothesized would recapitulate the adverse in utero environment experienced by the F1 males and resulting social dysfunction in the F2 …

Investigating the heritability of resistance fueling copy number variation in glyphosate resistant Amaranthus palmeri
… of resistance gene copies. I used 799 F1 progeny from 30 crosses to examine the following: (i) Is there a relationship between EPSPS copy number (CN) of offspring and mean of the parental pair copy number? (ii) Is there variability in the directionality of EPSPS inheritance with …

Small RNA and genome interactions in Chlamydomonas reinhardtii recombinants
… phenotypes can either be restricted to the F1 generation or be heritable throughout the hybrid lineage. While the mechanism behind heritable transgressive phenotyped is yet to be determined, transgressive gene expression is thought to be the root cause of their formation. Epigenetics …

Fat content and fatty acid composition of South African Wagyu beef
… in Japan. Most Wagyu’s for slaughter are of the F1 generation. This may affect the fat content and fatty acid (FA) composition of South African Wagyu beef. The fat content and the FA composition are influenced by many factors. Wagyu cattle are known to be genetically predisposed to produce vast …
