Summary The key regulator of salicylic acid (SA)‐mediated resistance, NPR1, is functionally conserved in diverse plant species, including rice ( Oryza sativa L.). Investigation depth needed to provide an understanding NPR1 ‐mediated resistance and a practical strategy for the improvement disease model crop rice. genome contains five ‐like genes. In our study, three homologous genes, OsNPR1 / NH1 , OsNPR2 NH2 OsNPR3 were found be induced by bacterial blight Xanthomonas oryzae pv. blast...
Abstract Salicylic acid (SA) plays a central role in plant disease resistance, and emerging evidence indicates that auxin, an essential hormone regulating growth development, is involved susceptibility. GH3.5, member of the GH3 family early auxin-responsive genes Arabidopsis (Arabidopsis thaliana), encodes protein possessing vitro adenylation activity on both indole-3-acetic (IAA) SA. Here, we show GH3.5 acts as bifunctional modulator SA auxin signaling during pathogen infection....
Global warming has profound effects on plant growth and fitness. Plants have evolved sophisticated epigenetic machinery to respond quickly heat, exhibit transgenerational memory of the heat-induced release post-transcriptional gene silencing (PTGS). However, how thermomemory is transmitted progeny physiological relevance are elusive. Here we show that HEAT SHOCK TRANSCRIPTION FACTOR A2 (HSFA2) directly activates H3K27me3 demethylase RELATIVE OF EARLY FLOWERING 6 (REF6), which in turn...
Global crop production is greatly reduced by vascular diseases. These diseases include bacterial blight of rice and crucifer black rot caused Xanthomonas oryzae pv. (Xoo) campestris (Xcc). The molecular mechanisms that activate defense against such pathogens remains underexplored. Here, we show an Arabidopsis MAPK phosphatase 1 (MKP1) mutant has increased host susceptibility to the adapted pathogen Xcc compromised in nonhost resistance Xoo. MKP1 regulates MAPK-mediated phosphorylation...
Significance Endoplasmic reticulum (ER)-associated degradation (ERAD) is a well-studied cellular process in yeast and mammalian systems. Recent molecular genetic studies the reference plant Arabidopsis have revealed that ERAD also conserved plants. Here we report an for degrading misfolded/mutant receptor-like kinases requires plant-specific protein, ethyl methanesulfonate-mutagenized brassinosteroid-insensitive 1 suppressor 7 (EBS7), localized to ER membrane induced by stress. Our...
Insects and pathogens release effectors into plant cells to weaken the host defense or immune response. While imports of some bacterial fungal plants have been previously characterized, mechanisms how caterpillar enter remain a mystery. Using live cell imaging real-time protein tracking, we show that HARP1, an effector from oral secretions cotton bollworm (Helicoverpa armigera), enters via protein-mediated endocytosis. The entry HARP1 depends on its interaction with vesicle trafficking...
Abstract Endoplasmic reticulum-associated degradation (ERAD) is a unique mechanism to degrade misfolded proteins via complexes containing several highly-conserved ER-anchored ubiquitin ligases such as HMG-CoA reductase degradation1 (Hrd1). Arabidopsis has similar Hrd1-containing ERAD machinery; however, our knowledge of this complex limited. Here we report two closely-related proteins, Protein Associated With Hrd1-1 (PAWH1) and PAWH2, which share conserved domain with yeast Altered...
In Arabidopsis , basic helix–loop–helix transcription factors (TFs) MYC2, MYC3, and MYC4 are involved in many biological processes, such as defense against insects. We found that despite functional redundancy, MYC-related mutants displayed different resistance to cotton bollworm ( Helicoverpa armigera ). To screen out the most likely genes insects, we analyzed correlation of gene expression with wild-type (WT) mutants. total, 94 untreated plants 545 wounded were strongly correlated insect...
Salicylic acid (SA) plays a critical role in plant immunity responses against pathogen infection, especially the establishment of systemic acquired resistance. Whether other forms salicylates also function has not been explored. Our previous study revealed that salicyloyl-aspartate (SA-Asp), only reported endogenous SA-amino conjugate plants, was highly accumulated Arabidopsis activation-tagged mutant gh3.5-1D after infection. In this study, we dissected SA-Asp production Arabidopsis. vitro...
The cross-talk between plant disease resistance and development is fundamental to understanding systemic physiological processes during pathogen attack. Our previous study showed that the Arabidopsis GH3.5 gene acts as a bifunctional modulator of salicylic acid (SA)-mediated auxin-mediated susceptibility Arabidopsis-Pseudomonas syringae interaction well development. Here, we further role mechanism involved in SA-dependent defense pathway. Transcript histochemical analysis promoter::GUS...
BRASSINOSTEROID-INSENSITIVE1 (BRI1) is a leucine-rich-repeat receptor-like kinase that functions as the cell surface receptor for brassinosteroids (BRs). Previous studies showed BRI1 requires its activity to transduce extracellular BR signal into nucleus. Among many reported mutant bri1 alleles, bri1-301 unique, glycine-989-to-isoleucine mutation completely inhibits in vitro but only gives rise weak dwarf phenotype compared with strong or null raising question of whether essential biological...
The green mirid bug (Apolygus lucorum) and the cotton bollworm (Helicoverpa armigera) are both preferred to live on but cause different symptoms, suggesting specialized responses of two insects. In this study, we investigated differential molecular mechanisms underlying plant defenses against A. lucorum H. armigera via transcriptomic analyses. At transcription level, jasmonate (JA) signaling was dominated in defense whereas salicylic acid (SA) more significant lucorum. A set...

Wounding is a common stress experienced by plants, resulting in quick elicitation of jasmonates (JAs). The widely accepted mechanism COI1-JAZ coreceptor posits that COI1 directly interacts with the active ligand JAs, whereas JAZs facilitate to trap binding pocket. Here we show multiple Arabidopsis undergo phase separation response wounding. Taking JAZ1 as an example, found it independent sensor JA-Ile, most plants. Under basal condition, dispersed MYC2 inhibit downstream gene expressions....
Endoplasmic reticulum-associated degradation (ERAD) is a key cellular process for degrading misfolded proteins. It was well known that an asparagine (N)-linked glycan containing free α1,6-mannose residue critical ERAD signal created by Homologous to α-mannosidase 1 (Htm1) in yeast and ER-Degradation Enhancing α-Mannosidase-like proteins (EDEMs) mammals. An earlier study suggested two Arabidopsis homologs of Htm1/EDEMs function redundantly generating such conserved N-glycan signal. Here we...
Abstract Both insects and pathogens release effectors that are transferred into plant cells weaken the host defense or immune response. While imports of some bacterial fungal plants have been reported, how caterpillar enter remains a mystery. Here, using live cell imaging real-time protein tracking, we show HARP1, an effector from oral secretions cotton bollworm ( Helicoverpa armigera ) which is previously reported to interfere with hormone jasmonate (JA) signaling output in plants, enters...
