In plants, innate immune responses are initiated by plasma membrane-located pattern recognition receptors (PRRs) upon of elicitors, including exogenous pathogen-associated molecular patterns (PAMPs) and endogenous damage-associated (DAMPs). Arabidopsis thaliana produces more than 1000 secreted peptide candidates, but it has yet to be established whether any these act as elicitors. Here we identified an A. gene family encoding precursors PAMP-induced peptides (prePIPs) through in-silico...
Abstract The successful recognition of pathogen-associated molecular patterns (PAMPs) as a danger signal is crucial for plants to fend off numerous potential pathogenic microbes. relayed through mitogen-activated protein kinase (MPK) cascades activate defenses. Here, we show that the Pseudomonas syringae type III effector HopF2 can interact with Arabidopsis thaliana MAP KINASE KINASE5 (MKK5) and likely other MKKs inhibit MPKs PAMP-triggered immunity. Inhibition PAMP-induced MPK...
Abstract Sessile plants encode a large number of small peptides and cell surface-resident receptor kinases, most which have unknown functions. Here, we report that the Arabidopsis kinase MALE DISCOVERER 1-INTERACTING RECEPTOR-LIKE KINASE 2 (MIK2) recognizes conserved signature motif SERINE-RICH ENDOGENOUS PEPTIDEs (SCOOPs) from Brassicaceae as well proteins present in fungal Fusarium spp. bacterial Comamonadaceae , elicits various immune responses. SCOOP trigger responses altered root...
Transformation of Chlamydia trachomatis should greatly advance the chlamydial research. However, significant progress has been hindered by failure C. to induce clinically relevant pathology in animal models. muridarum, which naturally infects mice, can hydrosalpinx a tubal also seen women infected with trachomatis. We have developed muridarum transformation system and confirmed Pgp1, -2, -6, -8 as plasmid maintenance factors, Pgp3, -5, -7 dispensable for vitro growth, Pgp4 positive regulator...
Plant cell walls undergo dynamic structural and chemical changes during plant development growth. Floral organ abscission lateral root emergence are both accompanied by cell-wall remodeling, which involves the INFLORESCENCE DEFICIENT IN ABSCISSION (IDA)-derived peptide its receptors, HAESA (HAE) HAESA-LIKE2 (HSL2). also act as barriers against pathogenic invaders. Thus, remodeling could have an influence on resistance to phytopathogens. Here, we identified IDA-like 6 (IDL6), a gene that is...
Guard cells shrink in response to drought stress and abscisic acid (ABA) signaling, thereby reducing stomatal aperture. Hydrogen peroxide (H 2 O ) is an important signaling molecule acting induce closure. As yet, the molecular basis of control over level H guard remains largely unknown. Here, leucine-rich repeat (LRR)—receptor-like kinase (RLK) protein HSL3 has been shown have ability negatively regulate closure by modulating cells. was markedly up-regulated treating plants with either ABA...
Plant immunity is initiated by cell surface-localized receptors upon perception of pathogen-derived microbe or pathogen-associated molecular patterns (MAMPs/PAMPs), damage/danger-associated (DAMPs), and phytocytokines. Different activate highly overlapping immune signaling at the early stage but divergent physiological responses late stage. Here, we indicate that plant elicitor peptide 1 (Pep1), a well-known DAMP, induces lignin callose depositions, two types for strengthening wall....
High temperature induces stomatal opening; however, uncontrolled opening is dangerous for plants in response to high temperature. We identified a high-temperature sensitive (hts) mutant from the ethyl methane sulfonate (EMS)-induced maize (Zea mays) library that linked single base change MITOGEN-ACTIVATED PROTEIN KINASE 20 (ZmMPK20). Our data demonstrated hts mutants exhibit substantially increased and water loss rate, as well decreased thermotolerance, compared wild-type under...
We previously reported that the Chlamydia trachomatis outer membrane complex protein B (OmcB) was partially processed in Chlamydia-infected cells. have now confirmed OmcB processing occurred inside live cells during chlamydial infection and not due to proteolysis sample harvesting. preceded by generation of active CPAF, a serine protease known be able cross inner via Sec-dependent pathway, suggesting CPAF is available for periplasm. In cell-free system, activity both necessary sufficient...
Phytocytokines are plant peptide signals perceived by plasma membrane-localized receptors in regulating immunity. It was recently reported that the phytocytokine SERINE-RICH ENDOGENOUS PEPTIDE12 (SCOOP12) is recognized receptor kinase MALE DISCOVERER 1-INTERACTING RECEPTOR-LIKE KINASE 2 (MIK2) and activates immune responses resistance to pathogens Arabidopsis. Here, we show Arabidopsis ENHANCER OF VASCULAR WILT RESISTANCE 1 (EWR1) four EWR1 close propeptide homologs encode functional SCOOP...
Various pathogenic species are capable of penetrating plant leaves through stomata on the leaf surface for propagation by absorbing nutrients in interiors. Plants have evolved abilities to close restrict pathogen infections. The model Arabidopsis (Arabidopsis thaliana) closes when FLAGELLIN SENSING2 (FLS2), a receptor protein localized plasma membrane (PM) stomatal guard cells, detects flagellin, pathogen-associated molecular pattern (PAMP) derived from bacterial Pseudomonas syringae. It...
Oidium heveae HN1106, a powdery mildew (PM) that infects rubber trees, has been found to trigger disease resistance in Arabidopsis thaliana through ENHANCED DISEASE SUSCEPTIBILITY 1 (EDS1)-, PHYTOALEXIN DEFICIENT 4 (PAD4)- and salicylic acid (SA)-mediated signalling pathways. In this study, typical TOLL-INTERLEUKIN RECEPTOR, NUCLEOTIDE-BINDING, LEUCINE-RICH REPEAT (TIR-NB-LRR)-encoding gene, WHITE RUST RESISTANCE (WRR4B), was identified be required for the against O. Arabidopsis. The...
A novel perylene pH probe for imaging of living cells in neutral to weak basic changes.
Innate immune system is employed by plants to defend against phytopathogenic microbes through specific perception of non-self molecules and subsequent initiation resistance responses. Current researches elucidate that mostly rely on cell surface-located pattern recognition receptors (PRRs) intracellular nucleotide-binding leucine-rich repeat proteins (NB-LRRs) recognize pathogen-associated molecular patterns (PAMPs) effector from microbial pathogens, initiating PAMP- effector-triggered...
Summary Oidium heveae , an obligate biotrophic pathogen of rubber trees ( Hevea brasiliensis ), causes significant yield losses worldwide. However, the molecular mechanisms underlying interplay between O. and remain largely unknown. In this study, we isolated strain, named HN1106, from cultivated H. in Hainan, China. We found that HN1106 triggers hypersensitive response a manner depends on effector‐triggered immunity proteins EDS1 (Enhanced Disease Susceptibility 1) PAD4 (Phytoalexin...
