Molecular basis of drought-induced susceptibility to the rice blast fungus Magnaporthe oryzae

ABSTRACT: In order to understand the mechanisms of Drought induced susceptibility (DIS) we’ve conducted a dual RNAseq experiment on rice infected tissues by Magnaporthe oryzae. At 4 days post inoculation tissues have been collected on mock inoculated and M. oryzae inoculated plants. Rice were conducted under two type of water regime: DIS Drought during three days before inoculation, NoDIS no drought before inoculation. RNAseq was conducted both on rice and fungal RNA.

DUAL RNASeq ANALYSIS REVEALS AN INCREASE OF FUNGAL PATHOGENICITY FUNCTIONS AND A ROLE OF PLANT GLUTAMINE SYNTHETASE IN NITROGEN-INDUCED SUSCEPTIBILITY TO THE RICE BLAST FUNGUS

Project description:In order to understand the mechanisms of Nitrogen induced susceptibility (NIS) we’ve conducted a dual RNAseq experiment on rice infected tissues by Magnaporthe oryzae. At 0 day post inoculation and 2 days post inoculation tissues have been collected on mock inoculated and M. oryzae inoculated plants. Rice were conducted under two type of nitrogen fertilization: 0N all fertilization but nitrogen, 1N all fertilization and NH4NO3. The fertilization was applied one day before inoculation. RNAseq was conducted both on rice and fungal RNA.

Transcriptome study of rice early response to rice blast fungus

Project description:Rice blast disease is a major threat to rice production worldwide, but the mechanisms underlying rice resistance to the causal agent Magnaporthe oryzae remain elusive. In this whole-genome transcriptome study of rice early defense response to M. oryzae, we applied Affymetrix Rice Genome Genechip to compare the compatible and incompatible rice-M. oryzae interactions in 24 hours post-inoculation. Leaf samples were harvested from three biological replicates of fungal- and mock-inoculated seedlings at 24 hours post-inoculation, from which RNA were extracted and analyzed with Genechip Rice Genome Array.

Comparison of transcriptional responses of two susceptible rice cultivars to strains of Xanthomonas oryzae

Project description:X. oryzae pv. oryzae (Xoo) is the causal agent of bacterial blight of rice. X. oryzae pv. oryzicola (Xoc) is the causal agent of bacterial streak of rice. Fourteen day old rice leaves were inoculated with one of five strains of Xanthomonas oryzae. Seven strains of Xoo were used; three wild type strains (PXO99A, T7174, and PXO86) and strains PXO99AME7, which has a nonfunctional type III secretion system and is non-pathogenic, , PXO99AME1, a pthXo6 and avrXa27 double mutant, PXO99ME2, a pthXo1 mutant, and PXO99ME5, a reduced virulence strain with uncharacterized mutation in a TAL effector. One strain of Xoc (BLS303) was tested. Controls include an inoculation with water (MOCK) and no inoculation. T7174 is our label for the Japanese isolate MAFF311018. Third leaves are inoculated with a needless syringe at adjacent sites along the upper leaf blade. Six leaves from separate plants are pooled. RNA samples were collected 24 h after treatment. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Ginny Antony.

Transcriptomic modulations triggered by Xanthomonas oryzae pv oryzae inoculation in rice

Project description:The transcriptomic modulations leading to defense response in rice one hour after inoculation by Xanthomonas oryzae pv oryzae. Xoo and mock inoculated plant of cultivars IET8585 (bacterial leaf blight resistant) and IR-24 (bacterial leaf blight susceptible) were compared.

Transcriptome analysis of rice ABA deficient mutant Osaba1-1 and wild-type before and 72h after Xanthomonas oryzae pv. oryzae (Xoo) infection

Project description:ABA deficient mutant Osaba1-1 exhibits great resistance to Xanthomonas oryzae pv. oryzae (Xoo) infection. To investigate gene expression profile changes at whole genome level between Osaba1-1 and wild-type (Nipponbare) rice during Xoo infection, we employed microarray expression profiling as a discovery platform. Osaba1-1 and wild-type rice plants about 6.5 leaf stage were used in this experiment. For Xoo inoculation, tips (about 3cm) of the fifth and sixth fully expanded leaves were cut off, and then immersed into Xoo (PXO99 strain) inoculum (suspended in sterile distilled water containing 10mM MgCl2, OD≈0.5) immediately for about fifteen seconds. Inoculated rice leaves were collected (approximately 2 cm leaf fragment from the inoculation site) at 0h and 72h post inoculation. Three independent replicate samples were collected at each time point for microarray.

Expression data from infected (Xanthomonas oryzae pv. Oryzae (P10)) leaf in japonica rice (cv. Y73)

Project description:Previously, we successfully introduce the bacterial blight resistance trait from Oryza meyeriana into O. sativa using asymmetric somatic hybridization with O. meyeriana as the donor species. After years of breeding, a progeny named Y73 was generated with recurrent parent O. sativa L. ssp. japonica cv. Dalixiang, and it shows high resistance to broad-spectrum of bacterial blight pathogens Xanthomonas oryzae pv. Oryzae (Xoo). However, the resistance mechanism of Y73 is remain undiscovered. To provide insights into the high resistance phenotype of these plants, we examined the transcriptome response in leaves of Y73 to the bacterial blight infection in this study. Xoo inoculated and mock inoculated rice plants were grown in growth room and the global analysis of gene expression events in rice leaves at 24 hours post inoculation (hpi) were analyzed using Affymetrix Rice GeneChip microarrays. We used microarrays to detail the global programme of gene expression underlying Xoo infection in rice Y73.

A single functional blast resistance gene Pi54 activates complex defense mechanism in Rice

Project description:To investigate the responses of resistance gene Pi54 at transcriptome level in blast resistant transgenic rice line TP-Pi54 during infection by Magnaporthe oryzae, we studied the co-expression analysis using microarray along with susceptible non-transgenic line Taipei 309 (TP). Suitable controls for both lines were used. The comparative analysis of differentially expressed genes was conducted. Total RNA from the leaves of mock inoculated non transgenic line Taipei 309 (TP) and transgenic line (TP-Pi54) along with challenge inoculated plants were isolated at 72 hours post inoculation. The samples were analyzed in two different biological replications (A and B) making total eight samples.
