Toward the understanding of TIR-NB-LRR–mediated immunity; study of the AvrRps4 recognition model in Arabidopsis
… plant innate immunity and is mainly mediated by NB-LRR resistance (R) proteins. However, the mechanisms by which NB-LRR proteins recognize effectors and induce downstream signaling events are poorly known. This PhD work focused on the characterization of TIR-NB-LRR–mediated immnunity in plants. …

An investigation of gene expression, alternative splicing and nonsense-mediated decay in potato in response to Phytophthora infestans infection
… nucleotide binding leucine-rich repeat (NB-LRR) proteins, leading to effector-triggered immunity (ETI). Using a NB-LRR gene enrichment and RNA-seq, previous studies identified over 700 NB-LRR genes in potato.<br/><br/>Dynamic changes in alternative splicing (AS) of NB-LRR genes have been …

Genome and Transcriptome Based Characterization of Low Phytate Soybean and Rsv3-Type Resistance to Soybean Mosaic Virus
… coil-nucleotide binding-leucine rich repeat (CC-NB-LRR) protein-encoding genes. This dissertation employed a comparative sequencing approach to narrow down the list of Rsv3 gene candidates to the most promising CC-NB-LRR gene. The evidence provided in this study clearly indicates a single …

Genes and mechanisms in Arabidopsis innate immunity against Leptosphaeria maculans
… revealed that resistance was dependent on TIR-NB-LRR resistance genes (RLM1Col and RLM2Ler), which were independent of signalling components previously associated to all TIR-NB-LRR resistance genes. RLM1Col was found to be responsible for L. maculans induced callose depositions. A segregant …

Detection of Acidovorax citrulli, the Causal Agent of Bacterial Fruit Blotch Disease of Cucurbits, Prevention via Seed Treatments and Disease Resistance Genes
… melo L.) and watermelon (Citrullus lanatus (Thunb.) Matsum and Nakai) belong to the family Cucurbitaceae. Bacterial fruit blotch (BFB) disease of cucurbits is an economically devastating plant disease that has caused an estimated loss of up to $450M on watermelon crops and $75M (worldwide) to …

A Comprehensive Analysis of Rust Disease Resistance in the Bioenergy Plant Switchgrass (Panicum virgatum L.)
… method was used to identify 1,011 potential NB-LRR R genes in the switchgrass genome (v 1.1). These potential R genes were characterized for polymorphism and expression differences between 'Alamo' and 'Dacotah'. Moreover, I found that some NB-LRR genes are developmentally regulated in …

The Genetic basis of resistance and susceptibility in the Albugo laibachii-Arabidopsis thaliana pathosystem
… 4 (RAL4). This locus contains three putative CC-NB-LRR class Resistance protein-encoding genes with similarity to Resistance to Peronospora parasitica 7 (RPP7). I demonstrated the utility of combined genomics approaches to identify recognized effectors without known motifs. The identification of …

Dissection of Regulatory Networks Mediating Resistance and Susceptibility of Arabidopsis thaliana to the Downy Mildew Pathogen Hyaloperonospora parasitica
… nucleotide binding-leucine-rich repeat (CC-NB-LRR) protein that activates race-specific resistance to the downy mildew pathogen, Hyaloperonospora parasitica (Hpa). Previously-published genetic epistasis tests have established that RPP7 activates defense responses through a signaling …

Gene expression and signaling in Rxo1 governed innate immunity in cereals
Many maize lines carry Rxo1, an NB-LRR gene that confers a rapid hypersensitive response (HR) after infiltration with the rice streak pathogen Xanthomonas oryzae pv. oryzicola (Xoc) or the maize stripe pathogen Burkholderia andropogonis (Ba) carrying the effector genes avrRxo1 or avrRba1 …

Engineering durable late blight resistance to protect solanaceous plants
… by the potato R3a protein, a member of the CC-NB-LRR type resistance gene family. However, the closely related virulent form, AVR3a<sup>EM</sup>, which is homozygous in more than 70% of wild <i>P. infestans</i> isolates, evades this recognition.Domain swapping experiments have revealed that the …

MicroRNAs and Trans-acting siRNA pathways in Apple (Malus x domestica Borkh.) and Peach (Prunus persica)
… from the miR390. Additionally, the miR482/2118-NB-LRR-siRNA pathway was found to be conserved, but evolved with distinct features, in apple and peach. Taken together, widespread and complex miRNA and tasiRNA regulatory networks have been adapted in apple and peach. They add another crucial layer …
