Characteristic Dissection of Xanthomonas oryzae pv. oryzae Responsive MicroRNAs in Rice.

Project description:MicroRNAs (miRNAs) are crucial player in plant-pathogen interaction. While the evidence has demonstrated that rice miRNAs mediate immune response to pathogens invasion, the roles of miRNAs on Xanthomonas oryzae pv. oryzae (Xoo) attack remain be in place. Herein, we monitored the responsive changes of rice miRNAs at 0, 8, 24 h across Xoo strain PXO86 infection in its compatible rice variety IR24 and incompatible variety IRBB5 by small RNA sequencing, and the genes targeted by miRNAs were also detected via degradome technology. The faithfulness of sequencing data was validated through quantitative real-time stem-loop reverse transcription-polymerase chain reaction assay. Bioinformatic analysis showed that the differentially expressed miRNAs could be divided into three immunity-related clusters, and 80 regulatory units were emerged in infection process, which comprises 29 differentially expressed known miRNAs and 38 cleaved targets. Furthermore, the miRNA presumptive function of separate immunity cluster in rice-Xoo interplay was confirmed through overexpressing osa-miR164a, osa-miR167d and osa-miR159b, and the disruption of regulatory units, osa-miR164a/OsNAC60, osa-miR167d-5p/OsWD40-174 and osa-miR159b/OsMYBGA, OsLRR-RLK2, OsMPK20-4, may reset rice defense response to Xoo infestation in a controllable manner. These findings provide new insights into the complex roles of characteristic miRNAs and their targets in rice-Xoo interactions.

A novel L-arabinose-responsive regulator found in the rice-blast fungus Pyricularia oryzae (Magnaporthe oryzae)

Project description:In this study we identified the L-arabinose-responsive regulator of Pyricularia oryzae that regulates L-arabinose release and catabolism. Previously we identified the Zn2Cys6 transcription factor (TF) AraR that has this role in the Trichocomaceae family (Eurotiales), but is absent in other fungi. Candidate Zn2Cys6 TF genes were selected according to their transcript profiles on L-arabinose. Deletion mutants of these genes were screened for their growth phenotype on L-arabinose. One mutant, named Δara1, was further analyzed. Our analysis demonstrated that Ara1 from P. oryzae is the functional homolog of AraR from A. niger, while sequence analysis did not reveal significant homology between them.

Transcriptome profile of rice genotypes ZH11 and Oseds1 by inoculation with Xanthomonas oryzae pv. oryzae

Project description:OsEDS1 is a key regulator of SA-mediated immunity in plants. The OsEDS1 knockout mutant (Oseds1) was characterized and shown to have increased susceptibility to Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc), suggesting the positive role of OsEDS1 in regulating rice disease resistance. To identify differentially regulated downstream of Oseds1, we performed transcriptome deep sequencing (RNA-seq) of wild type (ZH11) and Oseds1 inoculated with Xanthomonas oryzae pv. Oryzae (PXO99A).

Data-independent acquisition (DIA)-MS analysis for identification of Magnaporthe oryzae secreted protein induces cell death and triggers defense responses in rice

Project description:The rice blast disease, caused by Magnaporthe oryzae , devastates cultivated rice (Oryza sativa L.), resulting in extensive global crop loss. We employed a label-free quantitative proteomics approach to discover novel proteins associated with M. oryzae pathogenicity and rice defense. We identified 990 significantly modulated proteins in rice leaves including various pattern recognition receptors (PRRs) and pathogenesis-related (PR) proteins that were induced in response to M. oryzae inoculation. Additionally, 123 M. oryzae proteins were also identified and screened for their cell death-inducing activity by an in-silico approach. Among these, we found a novel protein MoXYL1 (endo-1,4-beta-xylanase) protein, which induces cell death in Nicotiana benthamiana leaves. Transgenic rice plants (PDUF26::MoXYL1) expressing MoXYL1 derived by rice domain of unknown function protein 26 (DUF26) promoter exhibited resistance against the M. oryzae and Cochliobolus miyabeanus and enhanced expression of pathogen-responsive genes and hormone-related genes. Furthermore, the application of data-independent acquisition (DIA) mass spectrometry (MS)-based proteomics on these transgenic rice plants revealed 1,833 significantly modulated proteins in response to M. oryzae, with 219 and 410 proteins responsive to MoXYL1 and M. oryzae, respectively. Based on these results, we propose a signaling network model induced by MoXYL1 and M. oryzae. In summary, our findings highlight the crucial role of MoXYL1 in rice innate immunity against M. oryzae and its potential to enhance rice disease resistance.

Dynamic and coordinated expression changes of rice small RNAs in response to Xanthomonas oryzae pv. oryzae

Project description:Endogenous small RNAs are newly identified players in plant immune responses, yet their roles in rice (Oryza sativa) responding to pathogens are still less understood, especially for pathogens that can cause severe yield losses. Here, we examined the small RNA expression profiles of rice leaves at 2, 6, 12, and 24 hours post infection of Xanthomonas oryzae pv. oryzae (Xoo) virulent strain PXO99, the causal agent of rice bacterial blight disease. Dynamic expression changes of some miRNAs and trans-acting siRNAs (ta-siRNAs) were identified, together with a few novel miRNA targets, including a disease resistance gene targeted by osa-miR159a.1. Coordinated expression changes were observed among some miRNA and ta-siRNAs in response to Xoo infection, with small RNAs exhibiting the same expression pattern tended to regulate genes in the same or functional correlated signaling pathways, including auxin and GA signaling pathways, nutrition and defense related pathways, etc. Highly abundant small RNAs with pathogen-responsive expression changes were identified from the exonic region of a protein-coding gene, which may present a new class of functional small RNAs. These findings reveal the dynamic and complex roles of small RNAs in rice-pathogen interactions, and identified new targets for regulating plant immune responses. Examination of the small RNA expression profiles of rice leaves at 2, 6, 12, and 24 hours post infection of Xanthomonas oryzae pv. oryzae (Xoo) virulent strain PXO99
