(Submitter supplied) We performed RNA-Seq of leaves of Oryza sativa L. ssp. japonica cv. Nipponbare 48 hours after inoculation with 10 geographically diverse strains of Xanthomonas oryzae pv. oryzicola, the causal agent of bacterial leaf streak. Results provide insight into the molecular basis of bacterial leaf streak, particularly the role of transcription activator-like effectors in the disease.

(Submitter supplied) We performed RNA-Seq of leaves of Oryza sativa L. ssp. japonica cv. Nipponbare 48 hours after inoculation with  Xanthomonas oryzae pv. oryzae strain PXO99A heterologously expressing the Tal2a effector, the designer TAL effector dT280 which targets a sequence overlapping the predicted Tal2a binding sequence in UCH, or the Tal11b effector. Results provide insight into the genes differentially regulated in a Tal2a- and dT280-specific manner.

(Submitter supplied) African Xanthomonas oryzae pv. oryzae strains seem most closely related to and share several genetic features with pathovar oryzicola despite causing symptoms of bacterial leaf blight. The ability of most Xanthomonas plant pathogenic bacteria to infect their host relies on the action of a specific family of type III effectors called the TAL effectors. These microbial transcription factors are injected into the plant and manipulate the host transcriptome upon binding to the promoters of plant genes. more...

(Submitter supplied) RESEARCH SUMMARY Bacterial blight and bacterial leaf streak, two of the most serious diseases of rice, are caused by Xanthomonas oryzae pathovar (pv.) oryzae (Xoo) and X. oryzae pv. oryzicola (Xoc) respectively. Xoo is a vascular pathogen that invades the xylem, whereas Xoc is non-vascular and colonizes the mesophyll apoplast. These distinctive types of infection represent the two most common ways plant pathogenic bacteria produce disease. more...

(Submitter supplied) In this study, using a novel dual RNA-seq approach we monitored the global transcriptional changes in real time of Xanthomonas oryzae pv. oryzicola and rice during infection. Our transcriptome maps of Xoc strains infecting rice provide mechanistic insights into the bacterias adaptive responses to the host niche, with modulation of central metabolism being an important signature. The study also uncovers that infected rice responds by substantial alteration of the cell wall, stress and structural proteins.

(Submitter supplied) affy_xoo_rice - affy_xoo_rice - The Bacterial Leaf Blight disease of rice is due to Xanthomonas oryzae pv. oryzae. As for many pathogenic bacteria, it relies on a type 3 secretion system that is devoted to the injection of type 3 effectors into the eukaryotic host cell. These proteins are meant to suppress host basal defense responses and/or mimic some host regulatory function promoting bacterial survey in the plant. more...

(Submitter supplied) TAL effectors are special family of type III effectors which can activate host gene expression at transcriptional level. The different induced genes in inoculated wheat leaves of wild type strain vs type III mutant are potential targets of TAL effectors.

(Submitter supplied) We used this microarray data to survey the differentially expressed genes in sweet orange by comparing leaves challenged with X. citri ssp. citri (Xcc) strain 306 with the pthA4 gene and leaves challenged with mutant Xcc306ΔpthA4 without the pthA4 gene 120 hours after inoculation. The deletion of the pthA4 gene reduced the virulence of Xcc306, and eliminated pustule formation. The gene expression changes after inoculation of these two strains represent PthA4-mediated molecular events in a susceptible reaction.
