Transcriptome analysis of Azospirillum lipoferum 4B during its interaction with rice roots

2014-01-01 | GSE42450 | GEO

The RNA-seq analysis of rice roots colonized by the endophytic bacterium Azoarcus olearius BH72 after one-, three- and seven-days post inoculation and after three days of boosted colonization.

Project description:Purpose: Transcriptional profiling of Oryza sativa japonica Nipponbare roots after one, three and seven days post inoculation with Azoarcus olearius BH72 (vs. non-inoculated controls) to understand the changes in transcriptomic response of rice roots to colonization by bacterial endophyte at initial stages of interaction; Additional set-up was included in which bacterial growth was boosted (through increasing 20-times carbon source - malic acid in the plant's hydroponic medium) to study rice roots transcriptome during enhanced colonization by the endophyte after three days post inoculation. Methods: Rice root mRNA profiles after one day, three days (including additional set-ups for boosted colonization), and seven days post inoculation with Azoarcus olearius BH72 and corresponding non-inoculated controls were generated by RNA sequencing, in triplicates, using Illumina NextSeq 500. Raw reads were then filtered, trimmed (PHRED > 33) and mapped onto IRGSP-1 version of Oryza sativa ssp. japonica cv. Nipponbare genome using CLC Genomics Workbench 8.5.1 (Qiagen, Germany). Expression of 17 selected genes was confirmed via RT-qPCR. Results: Using the RNA-Seq technology we obtained transcriptomic data from 24 sequencing libraries, with an average 46,181,160 clean reads per library, of which 87% or more were mapped onto the Oryza sativa ssp. japonica cv. Nipponbare IRGSP-1.0 genome (Fig. S3). We considered genes as differentially regulated (DEG) that exhibited at least 1.5-fold-change in expression level between Azo-colonized and non-colonized roots and FDR<0.05. Conclusions: Bacteria appeared to short-circuit the initial root defense responses for a compatible interaction during endophytic establishment, involving previously unknown putative rice candidate genes.

Transcriptome analysis of Azospirillum lipoferum 4B during its interaction with rice roots

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.

Host transcriptional reprogramming in response to the rice bacterial blight pathogen Xanthomonas oryzae pv. oryzae strain BLS354

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.

A phosphoproteomic landscape of rice (Oryza sativa L.) tissues

Project description:Here, we first reported the construction of a phosphoproteomic landscape of 6 tissues, including callus, leaves, roots, shoot meristem (SM), young panicles (YP) and mature panicles (MP), from Nipponbare (Oryza sativa ssp. japonica). By employing a non-gel, quantitative phosphoproteomic approach, a total of 4792 phosphopeptides from 2657 phosphoproteins were identified, which were found to be differentially phosphorylated among tissues.

Transcriptome and methylome interactions in rice hybrids

Project description:This research reports genome-wide measurements of genetic and epigenetic patterns of inheritance through an integrative analysis of BS-seq, RNA-seq, and siRNA-seq data in two inbred parents of the Nipponbare (NPB) and Indica (93-11) variety of rice and their hybrid offspring. We generated integrative maps of whole genome cytosine methylation profiles (BS-Seq), transcriptional profiles (RNA-seq), and small RNA profiles (sRNA-seq) to characterize two rice subspecies, Oryza sativa spp japonica (Nipponbare) and Oryza sativa spp indica (93-11) and their two reciprocal hybrid offspring using Illumina's sequencing-by-synthesis (SBS) platform .
