Exploring Genome Structure and Gene Regulation Related to Virulence in Fungal Phytopathogens Using Next Generation Sequencing Techniques
… pipelines of NGS data in the field of fungal phytopathogens using four different projects as examples. In a genome comparison project, sequenced short reads are de novo assembled to form a genome draft, then gene models are predicted either ab initial or assisted by RNA-Seq, followed by the …

The treatment of bacterial disease of plants by bacteriophage coated nanoparticles
Bacterial phytopathogens are a recurring issue for agricultural plants.Traditional control measures include copper treatment and use of pesticides and antibiotics. The use of bacteriophages that selectively kill the causative pathogen as an alternative treatment has been delayed by technical …

The Curious Poisoned Weed: Poison Ivy Ecology and Physiology
… but also aid in reduction of fungal endophytic phytopathogens. A survey of poison ivy urushiols yielded that while variation in urushiol congeners was high across individuals, relative congener levels were stable within individuals over a two month period. Lastly I demonstrate best practices for …

Genomic Evolution in the Oomycetes
… and proteomic investigations of the widespread phytopathogens Phytophthora chlamydospora, Phytophthora gonapodyides and Phytophthora pseudosyringae. Mass spectrometry analyses identified approximately 300 extracellular proteins per species, many of which are putativly involved in infection or …

Suppression and triggering of Arabidopsis immunity by Albugo species
Albugo species are obligate biotrophic phytopathogens. Like other biotrophs, they are anticipated to secrete effectors that can suppress or trigger plant defenses; the nature of Albugo effectors is currently unknown. Sequencing of A. laibachii isolate Nc14 (AlNc14) genome reveals 13032 genes …

The in planta role of the global regulator Lrp in the bacterial phytopathogen Pantoea stewartii subsp. stewartii
… as homologues from other closely related phytopathogens. This demonstrates that Lrp from P. stewartii and such homologues have evolved from a recent common ancestral gene. Examining the genomic islands present in P. stewartii, it is possible to begin to predict where some of the genes …

Endophytes as source of polypeptide and polyketide antibiotics fengycin and bacillaene
… They also have antagonistic effects against many phytopathogens. Utilization of these bacteria as a biological agent for protection of plants is an environmentally friendly alternative to chemical methods. Moreover, since plants belong to the eukaryotic organisms, antibiotics produced by …

In planta studies of the corn pathogen Pantoea stewartii subsp. stewartii and applications of a corn-based industrial byproduct
… but also other xylem-dwelling bacterial phytopathogens. In addition to exploring ways to enhance crop yield, an additional research area was on repurposing a byproduct of corn ethanol production, syrup. It was hypothesized that this corn-based syrup could be utilized as a carbon source to …

Functional Characterization of Four Xanthomonas euvesicatoria Type III Effectors
… nematodes, fungi, and bacteria. Among those phytopathogens, Xanthomonas euvesicatoria (Xe) causes a severe bacterial spot (BS) disease on pepper and tomato. The BS disease could cause a loss of approximately 10% of the total crop yield in the world. Breeding tomato and pepper cultivars with …

Der agglutinierende, antifungale Faktor aus den Knollen von Cyperus esculentus: Optimierung der Reinigung und weitere Untersuchungen zur Hemmung des Wachstums phytopathogener Pilze
Entsprechend den Vorarbeiten von C. Heid-Jehn1 wurde aus den Wurzelknöllchen der Pflanze Cyperus esculentus durch wässrige Extraktion ein Faktor isoliert, der als Cyperus-esculentus-Faktor (CEF) bezeichnet wurde. Die vorliegende Arbeit hatte das Ziel, die Isolierung und Reinigung zu optimieren, die …

Characterization of Novel Type VI Effectors of Acidovorax citrulli and Their Applicability to Biological Control of Plant Diseases
… suppresses the growth of multiple deleterious phytopathogens in planta and protects plant host. Transgenic plants expressing either full-length Hyde1 or its transmembrane domain demonstrate improved resistance against both bacterial and oomycete pathogens. Altogether, we characterize the T6SS …

Applying effectoromics and genomics to identify resistance against <i>Rhynchosporium commune</i> in barley
… secreted effectors have been identified in many phytopathogens including <i>R. commune</i>. <i>Rrs1</i> resistance, recognising the <i>R. commune </i>avirulence protein - AvrRrs1 (NIP1) has been deployed in the field to prevent infection but has soon proven ineffective. <i>R. commune </i>has …
