Characteristics of biological control agents and their antagonism against rice pathogens and pests
… pathogens (Rhizoctonia solani, Pyricularia oryzae, Fusarium moniliforme) were revived and cultured. I tested their potential activity against Xanthomonas oryzae pv. oryzae, Meloidogyne graminicola and Nilaparvata lugens. The results of these experiments (Chapter 2) showed that some …

Gene expression and signaling in Rxo1 governed innate immunity in cereals
… 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 respectively. Interestingly, when expressed as a transgene in rice, Rxo1 also confers a strong and …

Characterization Of A Novel Effector From Blumeria Graminis F. Sp. Hordei That Suppress Host Cell Death
… delivery of BEC1019 to the host cytoplasm via Xanthomonas type III secretion suppresses cultivar non-specific hypersensitive reaction (HR) induced by Xanthomonas oryzae pv. oryzicola, as well as cultivar specific HR induced by AvrPphB from Pseudomonas syringae pv. phaseolicola. BEC1019 homologs …

Exploiting rice diversity to uncover durable and broad-spectrum resistance
… of rice are essential. BB and BLS are caused by Xanthomonas oryzae pvs. oryzae (Xoo) and oryzicola (Xoc), respectively. This study aims to identify novel, broad-spectrum and durable sources of resistance to BB and BLS, and to pinpoint potential candidate genes for further characterization. We …

Structural and functional characterization of a Xanthomonas Type III effector
Rice bacterial leaf streak disease caused by Xanthomonas oryzae pv. oryzicola (Xoc) is one of the most important rice bacterial diseases. Xanthomonas type III effector gene avrRxo1 is conserved in diverse Xoc strains and its homologues have been identified from several other gram-negative bacteria …

Functional Characterization of Four Xanthomonas euvesicatoria Type III Effectors
… 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 improved BS …

Amyloidogenesis of a Type III-dependent Hpa1 and Structural analysis of a drug-pump repressor DNA complex
… Amyloidogenesis of Type III-dependent Hpa1 from Xanthomonas oryzae pv. oryzicola The first harpin, HrpN from Erwinia amylovora, the bacterium that causes fire blight of pear, apple and other rosaceous plants, was reported as an HR (hypersensitive response) elicitor in 1992. Similar harpins were …

Maize R gene Rxo1 Confers Disease Resistance on Pepper and Nicotiana benthamiana
… is threatened by the gram-negative bacterium Xanthomonas euvesicatoria (Xe) which causes bacterial spot (BS) disease, one of the most common and destructive diseases on pepper. Due to limited genetic resistance resources in host species, a promising strategy for controlling BS disease is to …
