Coumarins are important plant-derived natural products with wide-ranging bioactivities and extensive applications. In this study, we evaluated for the first time antibacterial activity mechanisms of action coumarins against phytopathogen Ralstonia solanacearum, investigated effect functional group substitution. We tested 18 different substitution patterns, found that daphnetin, esculetin, xanthotol, umbelliferone significantly inhibited growth R. solanacearum. Daphnetin showed strongest...
Ralstonia solanacearum thrives in plant xylem vessels and causes bacterial wilt disease despite the low nutrient content of sap. We found that R. manipulates its host to increase nutrients tomato sap, enabling it grow better sap from infected plants than healthy plants. Untargeted GC/MS metabolomics identified 22 metabolites enriched solanacearum-infected Eight these could serve as sole carbon or nitrogen sources for solanacearum. Putrescine, a polyamine is not source solanacearum, was...
Abstract To successfully infect plants, pathogens secrete effector proteins to the plant apoplast or inside cells, where they suppress immunity interfere with other cellular processes facilitate infection. Plant metabolism is crucial for most and plays a key role in defense against pathogens, making it major target pathogen effectors. Effector manipulate host provide nutrients indirectly chemical responses. Recent studies have shown that also utilize effectors shape microbiota composition by...
Bacterial wilt, caused by Ralstonia solanacearum, is a devastating disease resulting in tremendous losses of economic crops such as plants the Solanaceae. Recent studies showed that R. solanacearum spreading from lowlands to highlands China. We studied 97 Chinese strains were isolated four tobacco-growing zones over wide range elevations using phylotype specific multiplex polymerase chain reaction (Pmx-PCR) and phylogenetic relationships (egl mutS). The results all isolates belonged I, which...
Ralstonia solanacearum, the causal agent of bacterial wilt, can naturally infect a wide range host plants. The type III secretion system (T3SS) is major virulence determinant in this bacterium. Studies have shown that plant derived compounds are able to inhibit or induce T3SS some pathogenic bacteria, though no specific inhibitor inducer has yet been identified R. solanacearum. In study, total 50 different were screened and almost half them (22 50) significantly inhibited induced expression...
The MarR-family of transcriptional regulators are involved in various cellular processes, including resistance to multiple antibiotics and other toxic chemicals, adaptation different environments pathogenesis many plant animal pathogens. Here, we reported a new MarR regulator PrhN, which was the Ralstonia solanacearum. prhN mutant exhibited significantly reduced virulence stem colonization compared that wild type tomato plants. caused identical hypersensitive response (HR) on resistant...
Summary In Arabidopsis , the receptor‐like kinase (RLK) FERONIA (FER) senses peptide ligands in plasma membrane (PM), modulates plant growth and development, integrates biotic abiotic stress signaling for downstream adaptive responses. However, molecular interplay of these diverse processes is largely unknown. Here, we show that FER, receptor Rapid Alkalinization Factor 1 (RALF1), physically interacts with C2 domain ABA‐related (CAR) proteins to control nano‐organization PM. During this...
Abstract Transfer RNA (tRNA) can produce smaller fragments called tRNA-derived (tRFs). tRFs play critical roles in multiple cellular programs, although the functional mechanisms of remain largely unknown plants. In this study, we examined phenotype associated with 5′ tRF-Ala (tRF-Ala, produced from tRNA-Ala) overexpression and knockdown lines (tDR-Ala-OE tDR-Ala-kd, respectively) by which affects mRNA levels Arabidopsis (Arabidopsis thaliana). We investigated candidate proteins quantitative...
Receptor-like kinases (RLKs) constitute the largest receptor family involved in regulation of plant immunity and growth, but small-molecule inhibitors that target RLKs to improve agronomic traits remain unexplored. The RLK member FERONIA (FER) negatively regulates resistance certain soil-borne diseases are difficult control cause huge losses crop yields economy. Here, we identified 33 highly effective FER kinase from 1494 small molecules by monitoring autophosphorylation vitro. Four...
Abstract Some pathogens colonize plant leaves, but others invade the roots, including vasculature, causing severe disease symptoms. Plant innate immunity has been extensively studied in leaf pathosystems; however, precise regulation of against vascular remains largely unexplored. We previously demonstrated that loss function receptor kinase FERONIA (FER) increases resistance to typical bacterial pathogen Ralstonia solanacearum. Here, we show upon infection with R. solanacearum, root xylem...
Tiger lily ( Lilium lancifolium Thunb.) is a cash crop with long history of cultivation in China. Its roots have been used as valuable component Chinese medicine. Continuous cropping, the conventional planting approach for tiger lily, often leads to severe root rot disease, but it not yet clear how this method rot. In study, we analyzed rhizosphere microbiome and predicted microbial protein function planted continuous cropping three different geological types soil. order explore specific...
Tetranychus cinnabarinus is an important agricultural pest with a broad host range. We previously identified curcumin as promising acaricidal compound against T. . However, the mechanism of remains unknown. In this study, RNA-seq was employed to analyze transcriptome changes in treated or solvent. A total 105,706,297 clean sequence reads were generated by sequencing, more than 90% successfully mapped reference sequence. The 111 and 96 differentially expressed genes between curcumin-...
Soybean [ Glycine max (L.) Merr. ] is one of the most strategical oilseed crops that provides sustainable source protein and oil worldwide. Cultivation soybean severely affected by root-knot nematode (RKN). However, mechanism RKN parasitism to soybeans largely unknown. In this study, we identify GmLMM1 , which encodes a homolog FERONIA-like receptor kinase in soybean, as susceptible gene toward nematode. Mutations exhibit enhanced resistance against Meloidogyne incognita . RNA-sequencing...
Members of the Ralstonia solanacearum species complex (Rssc) cause bacterial wilt, a devastating plant disease that affects numerous economically important crops. Like other pests, Rssc injects cocktail effector proteins via type III secretion system into host cells collectively promote disease. Given their functional relevance in disease, identification effectors and investigation planta function are likely to provide clues on how generate pest-resistant crop plants. Accordingly, molecular...
The Catharanthus roseus RLK1-like (CrRLK1L) family is involved in the regulation of plant reproduction, growth and development, cell wall integrity sensing, as well responses to both biotic abiotic stress conditions. Extraordinary progress has been made elucidating CrRLK1L receptor kinases–mediated signaling pathway, while limited research addressed functions proteins tobacco. In this study, we identified analyzed 48 NtCrRLK1L members from tobacco genome. newly were divided into seven groups...
Ralstonia solanacearum, the causal agent of bacterial wilt, is a devastating plant pathogenic bacterium that infects more than 450 species. Until now, there has been no efficient control strategy against wilt. In this study, we screened library 100 plant-derived compounds for their antibacterial activity R. solanacearum. Twelve compounds, including harmine, harmine hydrochloride, citral, vanillin, and vincamine, suppressed growth solanacearum in liquid medium with an inhibition rate higher...
Abstract Plant roots exhibit localized immunity (LI) specifically in the root cap and transition/elongation zone (TZ/EZ). Such relies on receptor-like kinases at plasma membrane (PM), which are essential for plant response to bacteria rhizosphere. Here, we identified a new mechanism of action receptor kinase FERONIA (FER) LI. In absence bacterial stimuli, FER is PM, maintaining growth. When confronted with colonization, RALF23 peptide hyper-accumulates TZ/EZ cells activates metalloproteinase...
