Project description:Analysis of the transcriptome of the early developmental stages of the reproductive meristems of Oryza sativa ssp. Japonica cv Nipponbare. We compared the transcriptome obtained from osg1l2 single mutant to a wild type control
Project description:We performed RNA-Seq of leaves of Oryza sativa L. ssp. japonica cv. Nipponbare 48 hours after inoculation with Xanthomonas oryzae pv. oryzicola strain BLS354, 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. Examination of mRNA levels in Oryza sativa L. ssp. japonica cv. Nipponbare leaves at 48 hours after inoculation with Xanthomonas oryzae pv. oryzicola strain BLS354 with three biological replicates compared to three replicates of mock inoculated O. sativa as the control.
Project description: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. Examination of mRNA levels in Oryza sativa L. ssp. japonica cv. Nipponbare leaves at 48 hours after inoculation with 10 strains of Xanthomonas oryzae pv.oryzicola with three biological replicates for each compared to three replicates of mock inoculated O sativa as the control
Project description: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. Examination of mRNA levels in Oryza sativa L. ssp. japonica cv. Nipponbare leaves at 48 hours after inoculation. Each leaf was considered a separate biological replicate.
Project description:Drought often compromises yield in non-irrigated crops such as rainfed rice, imperiling the communities that depend upon it as a primary food source. In this study, two cultivated species (Oryza sativa cv. Nipponbare and Oryza glaberrima cv. CG14) and an endemic, perennial Australian wild species (Oryza australiensis) were grown in soil at 40% field capacity for 7-d (drought). The hypothesis was that the natural tolerance of O. australiensis to erratic water supply would be reflected in a unique proteomic profile. Leaves from droughted plants and well-watered controls were harvested for label-free quantitative shotgun proteomics. Physiological and gene ontology analysis confirmed that O. australiensis is responded uniquely to drought, with superior leaf water status and enhanced levels of photosynthetic proteins. Moreover, distinctive patterns of expression of proteins in drought were observed across the entire O. australiensis proteome. An intermediate impact of drought on photosynthetic and stress-response proteins is reported in O. glaberrima relative to O. sativa but the drought response was most striking in O. australiensis. For example, photosynthetic proteins decreased when O. sativa after drought, while a narrower range of stress-responsive proteins was up-regulated. Distinctive proteomic profiles and the expression levels of individual proteins with specific functions in response to drought in O. australiensis indicate the importance of this species as a source of stress tolerance genes.
Project description:The present study quantifies the transcriptomes of wild-type and transgenic Ubi::OsYHB rice seedlings (in the genetic background of Oryza sativa ssp. japonica CV Nipponbare) grown in the dark or under continous red light (Rc, at 50 µmol m-2 s-1) conditions.
Project description:Investigation of whole genome gene expression level changes in a Azospirillum lipoferum 4B associated to artificial roots, Oryza sativa japonica cv. Cigalon roots and Oryza sativa japonica cv. Nipponbare roots, compared to the strain grown in liquid culture. For each of the four condition, two replicates were analysed on an A. lipoferum 4B whole genome expression array designed by Roche Nimblegen, Inc. (Madison, WI, USA), based on the genome sequence (Wisniewski-DyM-CM-) et al. 2011), as follows: two replicates of 5 probes (length, 60 nucleotides) per gene, covering 6,242 genes and using a total of 62,178 probes.
