Characterization of the Pathway Leading to the Synthesis of Salicylic Acid in Plants Resisting Pathogen Infection.
<p>Salicylic acid is a plant hormone that accumulates with plant-pathogen interaction. This accumulation corresponds to the plant being resistant to infection and without it the plant is susceptible. In this study, primers of genes involved in the normal synthesis of SA were used in RT-PCR to …

Functional Study of Lipoxygenase-mediated Resistance to Fungal Pathogens in Maize for Milk-chain Safety and in Grapevine for Sustainable Viticulture
Fungal pathogens present a big concern in grapevine and maize production worldwide. Powdery mildew, a disease caused by an obligate biotroph, Erysiphe necator (En) is the most important fungal disease affecting grapevines, whereas. mycotoxin contamination of maize by Aspergillus flavus (Af) and …

Functional Analysis of Plant Glutamate Receptors
The plant glutamate receptors (GLRs) are homologs of mammalian ionotropic glutamate receptors (iGluRs) and are hypothesized to be potential amino acid sensors in plants. Since their first discovery in 1998, the members of plant GLRs have been implicated in diverse processes such as C/N ratio …

Understanding the role of host amino acid transporters in nutrient acquisition by oomycete pathogens
… (Hpa) is a naturally occurring oomycete pathogen on Arabidopsis thaliana. It is related to downy mildews of economically important crops such as cabbage, kale and broccoli, belonging to the Brassicaceae family. Downy mildew pathogens are obligate biotrophs that extract nutrients …

Phytophthora parasitica and lupin (Lupinus angustifolius) interactions: changes in gene expression during infection and after phosphite treatment
Phytophthora species are Oomycete pathogens that cause highly destructive diseases in a variety of agricultural and horticultural crops, and natural ecosystems. An understanding of the key biological processes that occur during development and infection of hosts is important for the development of …

AN INTEGRATED APPROACH TO THE DEVELOPMENT OF RESISTANCE TO COMMON BACTERIAL BLIGHT IN COMMON BEAN (PHASEOLUS VULGARIS)
… yet resistance is quantitative and influenced by pathogen diversity. Most known quantitative trait loci (QTLs) derive from Mesoamerican germplasm, leaving Andean market classes such as cranberry bean understudied. This thesis uses a multi‐scale approach, combining QTL mapping, transcriptomics and …
