The purpose of this study is to understand bacterial bioaerosols in industries that use different treatment methods and sampling methods in order to develop standardized limits, treatment measures, and remediation in an agricultural envir

However, studies on their ecology are lacking, despite knowledge of this being important for the development of sustainable risk assessment and pest management strategies, in part due to the morphologically cryptic nature of wireworms.

Mechanical wounding and insect feeding induce different transcriptional profiles in plants (Reymond et al. 2000). However, the molecular mechanisms underlying this difference are unclear.

Five caterpillar-specific Medicago truncatula genes were previously identified by cDNA-amplified fragment length polymorphism analysis (Darwish et al. 2008).

Abstract:

El problema de la salinidad y estrés hídrico continúa incrementando su importancia debido a la escasez cada vez mayor de agua para riego junto a la mala calidad de la disponible. La mejora genética de las plantas cultivadas para tolerar este tipo de estrés abiótico puede paliar en parte las consecuencias negativas de este problema. Sin embargo, la tolerancia a los estreses hídrico y salino es un carácter particularmente complejo ya que está compuesto por la interacción de muchos caracteres. Dentro de la sección Lycopersicon del género Solanum está incluido el tomate cultivado (Solanum lycopers

Abstract:

A series of three experiments were conducted to determine the diversity of indigenous chlorobenzoate (CB) degraders in soil and to investigate the use of different methods of bioaugmentation for remediation of contaminated soil. In the first study, soil was amended with either 500 or 1000 μg of 3-CB g⁻¹ and was either uninoculated or inoculated with the 3-CB degrader Comamonas testosteroni BR60. Bioaugmentation with C. testosteroni BR60 increased 3-CB degradation at both contaminant levels, and the increase was more pronounced at the higher level due to contaminant inhibition of indigenous 3-C

The biological and molecular properties of Sinaloa tomato leaf curl virus (STLCV) were investigated to test the hypothesis that STLCV is a previously uncharacterized whitefly-transmitted geminivirus from North America. STLCV causes leaf curling and yellowing in tomato plants. STLCV was transmissible to N. benthamiana by sap inoculation, and to Solanaceous and Malvaceous species by the whitefly vector. STLCV has transmission characteristics like other persistent viruses, and was not transovarially passaged. PCR fragments containing the large intergenic region (IR) of the STLCV A and B component

Abstract:

Molecularly imprinted polymers (MIPs) are biomimetic sensing elements that combine the accuracy and highly specific binding affinity of a biosensor, with the robustness and reusability associated with artificial electrochemical sensors. This thesis investigates the application of a MIP sensor to address the challenge of phosphate detection in precision agriculture. Traditional chemical sensing approaches using portable electrochemical sensors display a significant cross-interference between inorganic phosphate and other nutrient ions. This is due to the low position of phosphate in the Hofmeis

Abstract:

Blue oat mite species, Penthaleus spp. (Acari: Penthaleidae), and the redlegged earth mite, Halotydeus destructor (Tucker) (Acari: Penthaleidae), are some of the most serious and widespread agricultural pests in southern Australia. Management of these mites has been complicated by the recent discovery of three cryptic species of Penthaleus, whereas prior research had assumed a single species. The species differ markedly in their distribution, plant preferences and response to pesticides. This thesis looks at various aspects of the biology, ecology and molecular analyses of earth mites with par

Abstract:

Wheat (Triticum aestivum) kernel texture (hardness) is the most important determinant of milling and end-product quality. Recent data indicate that the only difference between soft and hard textured wheat is a single amino acid mutation in one protein, puroindoline-b (PIN-b). A rare tryptophan-rich domain in this protein consists of five tryptophan residues among a stretch of seven amino acid residues. To understand how this single mutation makes hard wheat possible, thus enabling bread making, it is crucial to have a high-resolution three-dimensional structure of this protein. The prerequisit

Abstract:

Plant mitochondria possess a gene expression system in which post-transcriptional events, such as transcript end maturation and turnover mechanisms play a key role in regulating the transcriptome. In addition, during early developmental stages of embryo germination, differing transcript profiles have been seen. This research focuses on two loci in wheat mitochondria, ccmFn-rps1 and rpl5-Psirps14-cox3, to elucidate the transcription and post-transcriptional events involved in their expression. Northern analysis of the ccmFN-rps1 genes during early seed-to-seedling development reveals a 3.2 kb

Abstract:

The fungus Nectria haematococca is a broad host range pathogen. Isolates pathogenic on pea are able to detoxify the phytoalexin pisatin using the enzyme pisatin demethylase. When the gene (PDA1 ) encoding this enzyme was mutated via gene disruption, the mutants were less virulent but still pathogenic on pea. Additional studies demonstrated that PDA1 was on a 1.6-Mb conditionally dispensable (CD) chromosome and that loss of this CD chromosome resulted in the complete loss of pea pathogenicity. This leads to the hypothesis that there are other pea p̱athogenicity (PEP) genes in addition to the P

Therefore, livestock may act as a source of contamination of the food and water supply.

Abstract:

Magnaporthe grisea is a filamentous ascomycete fungus that causes blast disease on rice and other grasses. Blast is a serious deterrent to rice production and negatively affects production of other cereals, forage crops and economically important grasses. The primary means of blast disease management involves the development and implementation of genetically resistant plants. Understanding the molecular basis of plant resistance is the foundation for the development of unique and durable plant protection. The results presented here focus on genes in the rice blast fungus called avirulence gene
