(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) 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) 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) A rice transcription factor OsMYC2 plays important role in the regulation of defense responses in rice. To clarify the OsMYC2-responsive genes, we performed a microarray analysis using the Agilent Rice Oligo Microarray (44k, Agilent Technologies, Redwood City, CA, USA). As a result, many defense-related genes including pathogenesis-related (PR) genes were upregulated in the OsMYC2-overexpressing transgenic rice.

(Submitter supplied) To dissect the molecular mechanisms of resistance mediated by Xa39,the transcriptome profiling of a rice line carrying Xa39 and its parents at the early stage of Xoo infection were investigated. A rice introgression line H471 carrying Xa39 exhibited a typical local hypersensitive response phenotype, accompanied by programmed cell death after inoculation with the Xoo Philippines’ race 9b.Our results indicated there might be cross-talk between the Xa39-mediated signal transduction cascades and the GA/BR signaling pathway, and the defense mechanism was related to diverse kinases, transcription factors, post-translational regulation, and R genes.

(Submitter supplied) An indica rice cultivar IET8585 (Ajaya), resists diverse races of the Xanthomonas oryzae pv oryzae (Xoo) pathogen attack, and is often cultivated as bacterial leaf blight (blb) resistant check in India. Earlier we reported a recessive blb resistance gene mapped to the long arm of chromosome 5 in IET8585. To further understand the mechanism of recessive and durable resistance response, two indica rice genotypes namely, i) IET8585 (Ajaya), a disease resistant indica veriety from India and ii) IR24, a bacterial leaf blight disease susceptible genotype were selected for this study. more...

(Submitter supplied) In response to bacterial infection, early transcriptional re-programming occurs in the host plant. We used microarrays to analyse the global transcriptomic response to Xoo. infection in a resistant rice cultivar (IR24). This was analysed in parallel with microarrays examining Xoo infection in a susceptible rice cultivar (IRBB21) as well as in response to Xoc [GSE19239], viral [GSE11025], parasite [GSE10373] and fungal [GSE7256, GSE18361] infections in rice, in order to identify common and distinct responses to biotic stress.
