Plant immunity often penalizes growth and yield. The transcription factor Ideal Architecture 1 (IPA1) reduces unproductive tillers increases grains per panicle, which results in improved rice Here we report that higher IPA1 levels enhance immunity. Mechanistically, phosphorylation of at amino acid Ser163 within its DNA binding domain occurs response to infection by the fungus Magnaporthe oryzae alters specificity IPA1. Phosphorylated binds promoter pathogen defense gene WRKY45 activates...
Crops carrying broad-spectrum resistance loci provide an effective strategy for controlling infectious disease because these typically confer to diverse races of a pathogen or even multiple species pathogens. Despite their importance, only few crop have been reported. Here, we report the identification and characterization rice bsr-k1 (broad-spectrum Kitaake-1) mutant, which confers against Magnaporthe oryzae Xanthomonas pv with no major penalty on key agronomic traits. Map-based cloning...
Abstract Hydrogen peroxide (H 2 O ) is a ubiquitous signal regulating many biological processes, including innate immunity, in all eukaryotes. However, it remains largely unknown that how transcription factors directly sense H Here, we report rice basic/helix-loop-helix factor bHLH25 senses to confer resistance multiple diseases caused by fungi or bacteria. Upon pathogen attack, plants increase the production of , which oxidizes at methionine 256 nucleus. Oxidized represses miR397b...
ABSTRACT Autophagy is essential for appressorium-mediated plant infection by Magnaporthe oryzae, the causal agent of rice blast disease and a major threat to global food security. The regulatory mechanism pathogenicity-associated autophagy, however, remains largely unknown. Here, we report identification functional characterization plausible ortholog yeast SNT2 in M. which term MoSNT2. Deletion mutants MoSNT2 are compromised autophagy homeostasis display severe defects autophagy-dependent...
Broad-spectrum resistance is highly preferred in crop breeding programmes. Previously, we have reported the identification of broad-spectrum resistance-Digu 1 (bsr-d1) allele from rice Digu. The bsr-d1 prevents activation Bsr-d1 expression by Magnaporthe oryzae infection and degradation H2 O2 peroxidases, leading to M. oryzae. However, it remains unknown whether defence pathways other than burst peroxidases contribute bsr-d1-mediated immunity. Blast was determined leaves spray punch...
Summary Plant transcription factors (TFs), such as basic helix‐loop‐helix (bHLH) and AT‐rich zinc‐binding proteins (PLATZ), play critical roles in regulating the expression of developmental genes cereals. We identified bHLH protein TaPGS1 ( T. aestivum Positive Regulator Grain Size 1) specifically expressed seeds at 5–20 days post‐anthesis wheat. was ectopically overexpressed (OE) wheat rice, leading to increased grain weight (up 13.81% 18.55% rice lines) size. Carbohydrate total levels also...
Leucine-rich repeat receptor-like kinases (LRR-RLKs) represent a large class of proteins in regulating plant development and immunity. The LRR-RLK XA21 confers resistance to the bacterial disease caused by pathogen Xanthomonas oryzae pv. (Xoo). Several binding have been characterized, however early events governing signaling not fully elucidated.Here we report identification one gene (XIK1) whose expression is induced rapidly upon infection with Xoo. Expression pattern analysis reveals that...
Previous studies have shown that multivesicular bodies (MVBs)/endosomes-mediated vesicular trafficking may play key roles in plant immunity and cell death. However, the molecular regulation is poorly understood rice. Here we report identification characterization of a MVBs-localized AAA ATPase LRD6-6 Disruption leads to enhanced death The activity homo-dimerization essential for its on An inactive mutation (LRD6-6E315Q) dominant-negative inhibition plants. protein co-localizes with MVBs...
Significant achievements have been made in breeding programs for the heavy-panicle-type (HPT) rice (Oryza sativa) Southwest China. The HPT varieties now exhibit excellent lodging resistance, allowing them to overcome greater pressures caused by heavy panicles. However, genetic mechanism of this resistance remains elusive. Here, we isolated a major quantitative trait locus, Panicle Neck Diameter 1 (PND1), and identified causal gene as GRAIN NUMBER 1A/CYTOKININ OXIDASE 2 (Gn1A/OsCKX2). null...
Abstract Parental or ancestral environments can induce heritable phenotypic changes, but whether such environment-induced changes are a common phenomenon remains unexplored. Here, we subject 14 genotypes of Arabidopsis thaliana to 10 different environmental treatments and observe genome-wide gene expression over four successive generations. We find that all caused with substantial proportion stably transmitted observed Intriguingly, the susceptibility genotype inductions could be predicted...
Receptor-like cytoplasmic kinases (RLCKs) represent a large family of proteins in plants. However, few RLCKs have been well characterized. Here, we report the functional characterization four rice - OsRLCK57, OsRLCK107, OsRLCK118 and OsRLCK176 from subfamily VII. These OsRLCKs interact with brassinosteroid receptor, OsBRI1 yeast cell, but not XA21 immune receptor. Transgenic lines silenced for each these genes enlarged leaf angles are hypersensitive to brassinolide treatment compared wild...
Summary Xanthomonas oryzae pv. is the causative agent of rice bacterial leaf blight. While type III secretion system X. essential for virulence, biochemical activities and virulence mechanisms non‐transcription activator‐like (non‐ TAL ) effectors delivered by this are largely unknown. Here, screening non‐ that contribute to we revealed outer protein K (XopK) inhibits pathogen‐associated molecular pattern‐triggered immunity upstream mitogen‐activated kinase cascades. Specifically, XopK...
Global food security is threatened by rice blast disease caused the filamentous fungus Magnaporthe oryzae. An understanding of resistance mechanisms fundamental to developing strategies for control. In this review, we summarize recent advances in pathogen-associated molecular pattern-triggered immunity, effector-triggered defense regulator-mediated and effects nutrient elements on resistance. We outline used breeding cultivars with improved also present major research challenges propose...
Auxin is an important phytohormone that regulates diverse biologic processes, including plant growth and immunity. Indole-3-acetic acid (IAA), known as one of the main forms auxin, able to activate However, it unknown whether IAA enhances resistance and/or suppresses fungal pathogen Magnaporthe oryzae. Here, we found could induce expression levels pathogenesis-related genes enhance disease control development blast through inhibiting M. oryzae infection. Exogenous suppressed mycelial delayed...
The brassinosteroid-SIGNALLING KINASE (BSK) belongs to the receptor-like cytoplasmic kinase XII subgroup. BSK1 regulates development and immunity in Arabidopsis. However, function of rice (Oryza sativa) is largely unknown. Here, we report that expression level OsBSK1-2 induced after a chitin or fagellin22 (flg22) treatment. Silencing results compromised responses chitin- flg22-triggered resistance Magnaporthe oryzae, but does not alter plant's architecture nor reduce plant brassinosteroid...
bsr-d1, an allele encoding a transcription factor identified from the rice cultivar Digu, confers durable, broad-spectrum resistance to infections by strains of Magnaporthe oryzae. bsr-d1 was predicted inhibit M. oryzae-induced expression Bsr-d1 RNA and degradation hydrogen peroxide achieve However, global effect biological process molecular function on blast mediated remains unknown. In this study, we compared transcriptomic profiling between knockout (Bsr-d1KO) lines wild type, TP309. Our...
Fungal pathogens typically use secreted effector proteins to suppress host immune activators facilitate invasion. However, there is rarely evidence supporting the idea that fungal secretory contribute pathogenesis by transactivating genes defense. We previously found pathogen Magnaporthe oryzae induces rice Bsr-d1 infection and hypothesized a mediates this induction. Here, we report MoSPAB1 M. directly binds promoter induce its expression, facilitating pathogenesis. Amino acids 103-123 of...
