Project description:Crop breeding for board-spectrum disease resistance is the most profitable strategy to control diseases. However, knowledge on genes and mechanism of board-spectrum resistance is very limited. We fund a rice mutant ebr1 (enhanced blight and blast resistance 1) showed broad-spectrum resistance to both bacterial Xanthomonas oryzae pv. oryzae and fungal Magnaporthe oryzae associated with spontaneous programmed cell death (PCD), autoimmunity activation and stunting. EBR1 is located at the chromosome centromere and encodes a previously unknown RING-type protein with E3 ubiquitin ligase activity. Extensive yeast two-hybrid screening identified one EIP (EBR1-interacting) protein, EIP1, which belongs to the BAG (Bcl-2 associated athanogene) family that have been associated with stress responses and modulation of cell death.cross kingdoms. We showed that EIP1 is a specially target of EBR1 and is a key player activating PCD and immunity including the salicylic acid and jasmonate defense pathways in rice. Its function is suppressed EBR1-mediated degradation through ubiquitination. EIP1-RNAi could restore the PCD and disease resistance phenotypes of ebr1, while EIP1 overexpression caused strong PCD and enhanced resistance to rice pathogens likely ebr1. Together, our study reveals a unique E3 ligase-BAD protein module that orchestrates autoimmunity and trade-off between defense and growth in rice.

Project description:Rice Xa21 resistance gene, which encodes a protein with predicted leucine-rich repeat (LRR), transmembrane, juxtamembrane, and intracellular kinase domains, conferred immunity to diverse strains of Xanthomonas oryzae pv. oryzae (Xoo). We generated Xa21 plant on TP309 background (Oryza Sativa Japonica). Systemic Acquired Resistance (SAR) in plants confers durable broad-spectrum resistance to pathogens and requires a phytohormone, salicylic acid (SA). Arabidopsis NPR1/NIM1 is a key regulator of the SAR response. Recently, we found that rice NPR1 homolog 1 (NH1) mediated enhanced resistance responses for Xoo (Chern et al., 2005b). We further investigated relating pathways in rice by identifying proteins that interact with NH1. One of them, constitutive over-expression of NH1 mediated negative regulator of resistance (NRR) gene caused enhanced susceptibility to Xoo , indicating that this gene product negatively affects to basal resistance response (Chern et al., 2005a). To dissect defense responses for rice bacterial blight pathogen, we planed microarray using two resistant mutant named with Xa21-TP309, NH1ox and one super-susceptible mutant (NRRox) before pathogen inoculation and one day post pathogen inoculation. Keywords: Biotic stress response

Keywords: Biotic stress response Two or Three-condition experiment, NH1ox vs wild type control (LG) at two durations of Xoo inoculation (0d and 1d); NRRox vs wild type control (LG) at two durations of Xoo inoculation (0d and 1d); and Xa21vs wild type control (TP309) at three durations of Xoo inoculation (0d,1d and 2d);. Biological replicates: 2 or 4, independently grown and harvested.

Project description:Crop breeding aims to balance disease resistance with yield; however, single resistance (R) genes can lead to resistance breakdown, and R gene pyramiding may affect growth fitness. Here we report that the rice Pigm locus contains a cluster of genes encoding nucleotide-binding leucine-rich repeat (NLR) receptors that confer durable resistance to the fungus Magnaporthe oryzae without yield penalty. Among these NLR receptors, PigmR confers broad-spectrum resistance, whereas PigmS competitively attenuates PigmR homodimerization to suppress resistance. PigmS expression, and thus PigmR-mediated resistance, are subjected to tight epigenetic regulation. PigmS increases seed production to counteract the yield cost induced by PigmR Therefore, our study reveals a mechanism balancing high disease resistance and yield through epigenetic regulation of paired antagonistic NLR receptors, providing a tool to develop elite crop varieties.

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. To find out pathways and genes involved in its high and board-spectrum resistance, microanalysis were carried out on Y73 after Xoo infection at 24 hours post inoculation (hpi). Three independant replicates were perfomed for each treatments.

Project description:Rice blast is one of the most serious diseases and is caused by Magnaporthe grisea. SHZ-2, an indica cultivar with broad spectrum resistance to multiple races of the blast pathogen, was crossed to TXZ-13, a blast susceptible but high-quality variety, to produce one BC3 line, BC10 line, which showed strong to moderate blast resistance over eight cropping seasons in the field. In this study, we compared the transcription between blast-resistant and -susceptive lines by custom microarray. Keywords: time course, blast infection, disease response Comparison between blast- and mock-infected rice. Biological replicates: 3 control (mock) and 3 blast-infected at each time point, independently grown and harvested at 24 and 48 hours after inoculation. Each sample was prepared with whole plant 5 cm above ground and was pooled from 5 plants grown under the same conditions.
