Realaus laiko PGR, taikomos patogeninių bakterijų identifikavimui maisto matricoje, optimizavimas /
Salmonella spp., Listeria monocytogenes ir Yersinia enterocolitica are attributed to the most common foodborne pathogens, that can be detected in such products as poultry, pork, raw vegetables and fruits. Real time PCR is an accurate and rapid method for quantitative identification of foodborne …

Nutritional and PGR effects on lipid unsaturation, osmoregulant content, and relation to bermudagrass cold hardiness
Winter injury of bermudagrass (Cynodon spp.) continues to be a problem across the transition zone. In an attempt to delay or induce winter dormancy while maintaining cold hardiness, applications of seaweed extract (SWE) (0.54 kg ha-1), ethephon (16 L ha-1), Fe (1 kg ha-1), and N (49 kg ha-1) took …

Stress Fiber Formation and Migration Are Novel PGR-Dependent Pathways Initiated in the Granulosa Cells of the Ovulating Follicle
… nuclear steroid receptor, progesterone receptor (PGR) is a master-regulator of these ovulatory events. Mice null for progesterone receptor (PRKO) fail to ovulate, however the pathways initiated by PGR that are essential to ovulation are not comprehensively understood. The overarching aim of this …

Soybean Response to Plant Growth Regulator Herbicides: Field Evaluation and Expression Analysis of Candidate Auxin -Responsive Genes
A lack of diagnostic tools specific to PGR herbicides often result in difficulty and confusion when responding to reported cases of soybean symptoms resembling PGR herbicide injury. PGR herbicides overstimulate the auxin hormonal pathway and induce gene expression. Identifying genes specifically …

NUCLEAR PROGESTIN RECEPTOR REGULATES FERTILITY AND SPAWNING IN FEMALE CICHLID ASTATOTILAPIA BURTONI
… we developed a CRISPR/Cas9 progestin receptor (Pgr) mutant. Pgr-mutant females are infertile with large ovaries and reduced spawning behaviors. I find that pgr regulates fertility by controlling ovulation similar to past Pgr knockout models (Chapter 2). I devised a radio frequency identification …

Nutrition and Plant Growth Regulator Rates for High Quality Growth of Containerized Spiderwort (Tradescantia virginiana L.)
… purpose was to determine fertilizer and PGR rates for high quality growth of Spiderwort in a greenhouse production setting. The first experiment screened three plant growth regulators (PGRs) at ascending rates on three T. virginiana cultivars. The most effective rates for height …

Physiology and Growth Responses of Cool Season Turfgrasses Treated With Trinexapac -Ethyl or Paclobutrazol
Plant growth regulators (PGRs) such as trinexapac-ethyl (TE) and paclobutrazol (PAC) are often routinely applied to highly managed turfgrasses to suppress clipping production, increase sward density, and enhance color. However, reports of variability in the seasonal responses of PGRs indicate …

The role of progesterone receptor in hypothalamic kisspeptin neurons
… the roles that the progesterone receptor (Pgr) and the androgen receptor have in progesteronic and androgenic regulation of kisspeptin-mediated GnRH release have not been investigated. Previous studies indicated that Pgr has a critical role in the induction of the GnRH-mediated preovulatory …

Responses of two grass species to plant growth regulators, fertilizer N, chelated Fe, salinity and water stress
… applications of two plant growth regulators (PGR) and/or chelated Fe (Na Fe diethylene triamine pentaacetate). Environmental variables considered were N levels, soil moisture regimes, and saline irrigations. The two materials investigated for PGR properties were a commercial product called …

A narrative inquiry exploring the nature of postgraduate research students' wellbeing
Research into postgraduate researcher (PGR) wellbeing has identified ways to mitigate risk and develop interventions for those identified as in need of support but the voices of those who have a sense of wellbeing are absent from the discussions. The marketised English higher education context …

Connectivity of dI3 Interneurons In the Development of Mice Spinal Cord
… reflexes such as the palmar grasp reflex (PGR) are known to disappear during development; presumably giving way to more volitional control of hand grasping. However, the underlying changes to the spinal circuitry responsible for this transition remain to be determined. dI3 INs, a class of …

An investigation into hormonal regulation of ovine mammary gland growth during pregnancy
… for receptor concentrations of progesterone (PGr), prolactin (PRLr) and insulin (Ir). Quantitative biochemical, histological and autoradiographical analyses were used to measure mammary gland growth and indicated no significant glandular growth occurs prior to 8O days of gestation. However, a …

Investigating population dynamics of Hoplolaimus galeatus and select associated relationships in creeping bentgrass putting greens
… qPCR diagnostic method. Plant growth regulators (PGRs) are used to optimize turfgrass growth and reduce management inputs, but anecdotal evidence suggests a link between increased PGR-induced phytotoxicity and high populations of lance nematodes One study investigated the relationship between PGR …

Optimizing Corn and Cotton Performance with Adaptive Management Systems and Subsurface Drip Irrigation in the Mid-Atlantic USA
… of dripline spacing, plant growth regulator (PGR) rates, irrigation strategies, N rates, and variety on yield. The first study integrated irrigation, in-season nutrient supplementation (soil and foliar applied), foliar fungicides, and biostimulants to enhance corn yields. Field trials …

Intensive management of barley in Saskatchewan
… (ICM) and to evaluate plant growth regulator (PGR) type, rate and time of application. The first experiment consisted of ten tests assessing ICM with three levels of N (0, 50 and 100 kg ha-1) above soil test recommendations, two levels of ethephon (0 and 0.24 kg ha-1) and two levels of …

Plant Growth Regulator Sprays and Girdling: Potential Horticultural Techniques to Increase Fruit Retention and Yield of Longan (Dimocarpus longan Lour.) Trees in California
… techniques, such as plant growth regulator (PGR) sprays and girdling, often increase fruit retention and yield of fruit tree crops, though effects are typically dependent on treatment timing and PGR concentration. The objective of this study was to identify PGR and girdling techniques that …

Influence of plant growth regulators on turfgrass polar lipid composition, tolerance to drought and salinity stresses, and nutrient efficiency
Two groups of plant growth regulators (PGRs), seaweed extract and triazole chemical, have been used in turfgrass management for improving turf quality and strengthening turfgrass tolerance to environmental stress. In order to understand the physiological functions and stress-tolerance mechanisms of …

Intramammary infection in rapidly growing, non-lactating mammary glands
… receptor α (ESR1) and progesterone receptor (PGR), as well as staining characteristics of ESR1 and PGR positive nuclei was also examined in these tissues. No appreciable differences were observed in any of the examined ESR1 and PGR measures between Staphylococcus aureus and saline mammary …
