Requirement of phosphoinositol-derived signals in the wounding response of Arabidopsis thaliana
Die pflanzliche Wundantwort ist in der Verteidigung gegen Fraßfeinde von zentraler Bedeutung und daher streng reguliert. Das Isoleucinkonjugat der Jasmonsäure (JA-Ile) ist dabei eines der wichtigsten regulatorischen Moleküle. In dieser Dissertation wurden Phosphoinositide (PI), die vorher nicht als …

An evaluation of wounding and hormone on the rooting of cutting : A thesis submitted in partial fulfilment of the requirements for the National Diploma in Horticulture in New Zealand
Wounding the basal tissues of many different types of cuttings from a wide range of plant material has been the standard practice of many nurserymen throughout the world. This practice has been passed onto new generations of plant propagators as a successful technique for propagating many different …

The role of bone morphogenetic protein signalling in the control of skin repair after wounding. Cellular and molecular mechanisms of cutaneous wound healing mediated by bone morphogenetic proteins and their antagonist Noggin.
Bone morphogenetic proteins (BMPs) and their receptors (BMPRs) coordinate tissue development and postnatal remodelling by regulating proliferation, differentiation and apoptosis. However, their role in wound healing remains unclear. To study this, transgenic mice overexpressing Smad1 (K14-caSmad1) …

Microrna Functions In Uv-Induced Cutaneous Squamous Cell Carcinoma
… for which long term UV exposure and chronic wounding are the dominant risk factors. Despite these clinically established connections, little is understood about the early molecular response of human skin to UV exposure and its connection to acute wounding and cuSCC. Thus, our goal is to find …

The role of hormones in wound-stress response in Arabidopsis thaliana
Wounding stress is a continuous threat to the survival of all organisms, and, in crop plants it leads to a dramatic reduction in crop yield. The signaling pathways that allow plants to respond to wounding stress are known to be complex. Many plant hormones such as jasmonic acid (JA), salicylic acid …

Effect of treadmill exercise on cutaneous wound healing in obese mice
… and measured wound area to day 10 post-wounding. Additionally, we measured non-wounded skin and wound site inflammation and growth factor expression through gene and protein expression analyses at baseline and at days 1, 3, and 5 post-wounding. Further parameters measured included …

Characterizing maize resistance to Clavibacter nebraskensis
… characteristic of the disease. In the absence of wounding, the bacteria colonized leaf tissue via the hydathodes when guttation droplets were present. Stomatal penetration was not observed under natural conditions. Bacteria forcibly infiltrated into the mesophyll did not cause typical disease …

Propagation of Cupressus lusitanica by cuttings: A thesis submitted in partial fulfilment of the requirements for the National Diploma in Horticulture (Hons.) of the Royal New Zealand Institute of Horticulture
… especially in the spring and autumn. Several wounding techniques were used in Experiment 3; Single Wound, Double Wound, Heel and Control. Certain clones were found to be easier to strike than others. A range of hormone concentrations was used from O ppm I.B.A. to 10,000 ppm I.B.A. Success …

Exploring the Interface Between Macroorganisms and Microorganisms: Biochemical, Ecological, and Evolutionary Contexts
… </p><p>I demonstrated that self-wounding is inherent to the critical period of settlement and metamorphosis, in barnacles. Wounding occurs during cuticle expansion and organization and generates proteinaceous secretions, which function as a secondary mode of attachment that …

ANATOMICAL AND PHYSIOLOGICAL ASPECTS OF A HOST-PATHOGEN INTERACTION: CYTOSPORA CANKER ON PRUNUS PERSICA (L) BATSCH
… Formation. Changes occurring in response to wounding and wounding plus inoculation were monitored over a one year period. Gum ducts were produced in the xylem to form a barrier zone in both treatments. NP formed at a faster rate in uninoculated samples. In addition, wound periderms in …

Purification and Characterization of 5'-Methylthioadenosine Nucleosidase From Avocado and Tomato
… during fruit development. The effects of wounding on MTA content and MTA nucleosidase activity were also assessed. Results suggested that the methionine salvage pathway in non-ripening mutant tomatoes was also active but at a reduced rate.

Identification of common and unique stress responsive genes of Arabidopsis thaliana under different abiotic stress through RNA-Seq meta-analysis
… including drought, heat, cold, salt, light and wounding. We developed a multi-step computational pipeline, which performs data downloading, preprocessing, read mapping, read counting and differential expression analyses for RNA-Seq data. We found that 5729 and 5062 genes are induced or repressed …

Control of Passive Influx of Calcium in Corn Root Tissue (calcium-2+ Channels, Ion Transport, Voltage-Regulator, Injury, Cold Shock)
… or shocks such as low and high temperatures, wounding, low pH, or application of metabolic inhibitors which lead to depolarization of the cell potential, increase the passive entry of Ca('2+) to the cells. Voltage-control is lost upon severe injury, and the control is recovered by washing the …

Gene regulation in a pathogen-plant interaction: soft rot erwinias versus potato tubers

Identification of an extracellular adenosine 5'-triphosphate receptor in Arabidopsis thaliana
… MAPK activation, or altered gene expression. Wounding of the plant can release up to 40 æM ATP in the wound site. Consistent with this, ectopic expression of DORN1 increased the plant response to physical wounding. We propose that DORN1 is essential for perception of extracellular ATP and …

Aging Delays and Exercise Accelerates Wound Healing and Decreases Inflammation in Old Mice
… 30 minutes/day for eight days, three days before wounding, and five days afterwards. Mice were given four full thickness dermal wounds using a 3.5mm punch biopsy instrument and wounds were photographed for 10 days. After the old mice fully healed (approximately 3 months), they were wounded again …

Some Effects of Turnip Yellow Mosaic Virus Infection on Nucleic Acid Metabolism in Brassica Pekinensis Rupr.

Dissecting the Transcriptional Regulatory Network Underlying Plant Wound Suberin Biosynthesis
