SNP ANALYSIS FOR DROUGHT-RELATED CANDIDATE GENES IN A GERMPLASM COLLECTION AND A TILLING POPULATION OF ITALIAN RICE
… candidate genes was then explored in a TILLING population developed in the Italian rice variety Volano. The Volano TILLING platform was validated through the screening of three relevant target genes. A mutation density of 1/374 kb was estimated, proving the effectiveness of this approach …

Tilling the Field of Rural Arts Education in Canada: The Role of Intermediary Organizations in Brokering and Supporting Partnerships
Intermediary organizations (IOs) are described across sectors as third-party entities that broker, guide, support, and evaluate partnership initiatives. This multiple-paper dissertation examines the work of IOs in supporting arts education partnerships in rural communities. The introductory chapter …

Aspects of Some Compacted Campground Ameliorating Practices
… to an acceptable level in three years. Roto-tilling alone was the least effective treatment. Roto-tilling and the addition of bark or chips to maintain the loose soil structure and low bulk density had very good results. These results could be sustained by planting of grasses during the off …

Canada thistle (Cirsium arvense [L.] Scop.) response to mowing, herbicide, competitive grasses, and soil amendments on wetland, upland, and mesic sites
… produced effective control. In Field Study II, tilling enhanced herbicide effectiveness. Organic matter or manganese alone did not reduce Canada thistle growth. Manganese addition reduced herbicide effectiveness. In both field studies, neither mowing nor grass seeding enhanced herbicide …

Habitat models for plant functional groups with respect to soil parameters and management
… disturbances of the vegetation cover by roto-tilling, to preserve the local and regional floristic species pool. For this purpose presence/absence data of the occurring plant species were recorded along with abiotic parameters such as soil and climatic factors and management strategy on …

Signaling mechanisms and developmental function of fibroblast growth factor receptors in zebrafish
… influences Fgf8 signaling range. Through TILLING mutant recovery and morpholino knockdown studies we also show that Fgfr2 is required for growth and skeletal development in zebrafish, whereas Fgfr4 is required for pectoral fin specification and growth.

Strip-till flue-cured tobacco production in Virginia
… a conservation tillage system that only requires tilling a small strip before transplanting, has been shown to be effective for tobacco producers in southside Virginia. The cost of fertilizer in recent years and the loss of applied nutrients has brought new attention to the impact of cover crops …

Interactive Effects of Cover Crops, Invertebrate Communities and Soil Health in Corn Production Systems
… used practices such as using cover crops, not tilling, and abandoning the use of insecticide. The comparative system, a conventional management system, consisted of practices such as no cover crop or a period of bare soil, use of tillage, and use of insecticidal techniques. In this study, …

Mechanism of cell adhesion at the midbrain-hindbrain neural plate in the teleost Danio rerio
… genetic mutant lines in cooperation with the Tilling facility at the Max-Planck-Institute. The only acquired potential null mutant ephrinB2bhu2971 was analyzed and characterized further. I observed that a knock down or knock out of only one of the ephrinB2 ligands does not seem to be …

Characterization of the Role of Mcm10 in DNA Replication in Drosophila melanogaster
… of over 20 missense mutations generated via a Tilling approach. Mitotic index data generated using brain cells of these mutant strains showed no delays in progression through M-phase of the cell cycle. Interestingly though, several aberrant chromosomal phenotypes such as condensation defects, …

The Nexus of Climate Change, Biodiversity, and Food Security: A Brazil Case Study
… practices such as monocropping and heavy tilling.” The current trade-offs and compromises between food production on the one hand and climate and biodiversity on the other are unsustainable in the long term. This unsustainable dynamic between food, climate, and biodiversity can be seen …

IDENTIFICATION AND CHARACTERIZATION OF GENETIC LOCI FOR CULM MORPHOLOGY TRAITS IN BARLEY (HORDEUM VULGARE L.)
… based on high expression in internodes. Two TILLING lines from the HorTILLUS population (hvcen1.h and hvcen1.r) were identified as carrying mutations with potential impact on protein function and evaluated for their effects on plant and culm development under greenhouse conditions. Compared …

Macroinvertebrate Response to Management Strategies and Habitat Condition at Kealia Pond NWR, Maui, Hawaii
… distribution were measured in response to roto-tilling treatments, microhabitat variables, and tilapia predation. Monocultures of exotic vegetation were roto-tilled to increase plant diversity and open-water/vegetation interspersion for foraging and breeding Hawaiian Stilts (Himantopus mexicanus …

Mass, Composition, Source Identification and Impact Assessment for Fine and Coarse Atmospheric Particles in the Desert Southwest
… observations show higher concentrations during tilling and harvesting indicating the large role agricultural sources play on particle concentrations in this area. Chemical characterization and modeling show that re-entrained road dust is a significant factor. Fine particle modeling results …

Broad-scale Assessment of Crop Residue Management Using Multi-temporal Remote Sensing Imagery
… changes in agricultural surfaces caused by tilling, planting, and crop emergence at the start of the growing season. The first study addressed this difficulty by extracting minimum values of multi-temporal NDTI (Normalized Difference Tillage Index) spectral profiles, designated here as the …

Fertility and the economic value of children: evidence from Nepal
… are complements since children can assist in tilling the land. Remittances are purported to affect fertility through increasing son preference. This is because remittances provide security and sons send remittances.<br/><br/>Support is found for all the hypothesised relationships. This implies …

The interdependent regulation of photosynthesis and the circadian clock in wheat
… circadian clock on photosynthesis two tetraploid TILLING lines containing double null mutations of elf3 (Chapter 4) and gi (Chapter 5) were screened using a combination of chlorophyll a fluorescence, leaf temperature and time-course RT-qPCR. In both cases mutation of circadian clock genes caused a …

Untersuchungen zu Regulatoren der Flavonoidbiosynthese in Arabidopsis thaliana : eine Studie zu neuen Funktionen bekannter Proteinklassen
… number of new TT1 alleles was identified by the TILLING method. Those alleles are now available for the molecular characterisation of TT1. Moreover five homologues of TT1, which form the WIP gene family in A. thaliana together with TT1, were analysed concerning expression profiles, intracellular …

Reverse genetics analysis of biological functions of zinc transporters Znt1 (Slc30a1) & Zip10 (Slc39a10) in zebrafish
… sa0014 was created by the Sanger Centre using TILLING technology. The mutant fish carries a premature stop codon in the znt1 (slc30a1) gene resulting in a protein that is forty (40) amino acids shorter than the wild- type. A colony of this strain was generated and the mutation studied for its …
