Project description:Endophytic colonization is a very complex process which is not yet completely understood. Molecules exuded by the plants may act as signals which influence the ability of the microbe to colonize the host or survive in the rhizosphere. Here we investigated whether root exudates of the host might play a role in initiating the endophyte-rice interaction. The whole genome microarray approach was used to investigate the response of the diazotrophic model endophyte, Azoarcus sp. strain BH72, to exudates of O. sativa cv. Nipponbare in order to identify differentially regulated genes. Azoarcus sp. strain BH72 was grown in the presence or absence of root exudates of Oryza sativa cv. Nipponbare for two different time points, and differences in the gene expression profile were monitored.

Project description:To investigate the root system, three indoor cultivation systems, including water agar, deep water, and vermiculite-based hydroponics, are commonly used. However, their effects on the root development of rice (Oryza sativa L.) remain unknown. In this study, we assessed the effect of these indoor cultivation systems on the maximum root length (MRL) and examined the changes in phosphorylated protein profiles by LC-MS/MS.

Project description:affy_meloidogyne_rice - affy_meloidogyne_rice - Plant-parasitic nematodes cause profound economic losses to global agriculture with the obligate sedentary endoparasitic varieties; amongst them the cyst and Root Knot Nematode (RKN) species are the most damaging. Meloidogyne graminicola is a RKN mainly found in the monocotyledous plants. In the compatible interaction with Oryza sativa, M. graminicola induces the characteristic formation of hook-like galls resulting from the redifferentiation of root cells into multinucleate giant cells. In order to understand the global transcriptome changes occurring during infection, several recent microarray studies on root knots have demonstrated complex changes in host plant gene expression in response to infection. However, to our knowledge, all these transcriptome studies were performed on dicotyledous plants. A histological study enabled us to observe hyperplasia and hypertrophy of the surrounding cells leading to the formation of hook-like galls. We also investigated the plant response to M. graminicola by carrying out a global analysis of gene expression during gall formation in rice, using giant cell-enriched root tissues at an early stage (2dpi) and a latter stage (4dpi) of gall development.-Oryza sativa (var. Nipponbare) seedlings were grown on 6 cm3 SAP substrate completed with diluted Hoaglands solution (Reversat et al., 1999). Culture units were placed in a growth chamber illuminated with fluorescent tubes 9/24 h and maintained at 23°C for 5 days before being inoculated with a 100 J2-stage juveniles M. graminicola. One day after inoculation (dai), the rice seedlings were immersed in de-ionised water to remove all J2s that had not penetrated the roots and allowing synchronization of the infection. Each seedling was transferred to a hydroponic mini chamber (Reversat et al., 2004). Sampling was performed at 2 and 4 dai and each of them contained galls from 70 infected plants, they were then hand-dissected, frozen in liquid-nitrogen and stored at -80°C. As reference samples, uninfected meristematic root fragments were dissected from seedlings grown under the same conditions. Each sample was replicated 3 times.

Project description:To evaluate the roles of gene regulation in Oryza sativa leaf, dynamic profiles of transcriptome were investigated in Oryza sativa L. spp. indica with different treatments, the aerial tissues of one-month-old plants from four different areas (groups 1–4) were treated with 0, 40 mL of 25% azoxystrobin, 0.01 g of VdAL, or 40 mL of 25% azoxystrobin plus 0.01 g VdAL, respectively.

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.

Project description:Iron (Fe) is an essential micronutrient for almost all organisms. However, Fe is frequently inaccessible to plants. To acquire insoluble Fe from soil, rice (Oryza sativa L.) plants employ a Combined Strategy, which is composed by all features of Strategy II, common to all Poaceae species, and some features of the Strategy I from non-Poaceae. To understand the evolution of Fe uptake mechanisms, we analyzed the root transcriptomic response to Fe deficiency in two species from the Oryza genus: O. sativa and its wild progenitor O. rufipogon. A total of 622 and 2,017 genes were found to be differentially expressed in O. sativa and O. rufipogon, respectively. Among the genes regulated in both species, we found the Fe transporters associated with Strategy I, such as IRT1, IRT2 and NRAMP1; and genes associated with Strategy II, such as YSL15 and IRO2.
