Root exudates serve as chemical signaling molecules that regulate rhizosphere interactions and control soil-borne diseases. The between plants the soil microbiome play dynamic crucial roles in regulating resistance of to biotic stress. However, specific many root plant pathogens remain unclear. exudate methyl ferulate, a naturally occurring relatively non-toxic antifungal agent, has been applied postharvest preserve foodstuffs not used disease control. This study investigated role ferulate...
Tobacco black shank caused by Phytophthora nicotianae is a serious disease in tobacco cultivation. We found that naringenin key factor causes different sensitivity to P. between resistant and susceptible tobacco. The level of basal flavonoids was distinct from Of all with content, showed the best antimicrobial activity against mycelial growth sporangia production vitro. However, very low or no other plant pathogens. induced not only accumulation reactive oxygen species, but also expression...
Nicotiana tabacum is an allotetraploid hybrid of sylvestris and tomentosiformis a model organism in genetics. However, features subgenome evolution, expression coordination, genetic diversity complex traits regulation N. remain unresolved. Here we present chromosome-scale assemblies for all three species, genotype phenotypic data 5,196 germplasms. Chromosome rearrangements epigenetic modifications are associated with genome evolution coordination following polyploidization. Two subgenomes...
The TIFY gene family plays an essential role in plant development and abiotic biotic stress responses. In this study, genome-wide identification of members tobacco their expression pattern analysis response to Ralstonia solanacearum infection were performed. A total 33 genes identified, including the TIFY, PPD, ZIM&ZML JAZ subfamilies. Promoter results indicated that a quantity light-response, drought-response, SA-response JA-response cis-elements exist promoter regions. exhibited expansion...
Bacterial wilt (BW) caused by Ralstonia solanacearum is a globally prevalent bacterial soil-borne disease. In this study, transcriptome sequencing were subjected to roots after infection with the R. in resistant and susceptible tobacco variety. DEGs that responded both contributed pectinase peroxidase development enriched plant hormone signal transduction, transduction MAPK signalling pathway KEGG terms. Core response cell wall, membrane, abscisic acid ethylene qRT-PCR indicated...
Abstract Background Tobacco mosaic virus (TMV) is a widely distributed viral disease that threatens many vegetables and horticultural species. Using the resistance gene N which induces hypersensitivity reaction, common strategy for controlling this in tobacco ( Nicotiana tabacum L . ). However, gene-mediated has its limitations, consequently, identifying genes from resistant germplasms developing cultivars an ideal damage caused by TMV. Results Here, we identified highly TMV-resistant...
Multiparent Advanced Generation Inter-Cross (MAGIC) population is an ideal genetic and breeding material for quantitative trait locus (QTL) mapping molecular breeding. In this study, a MAGIC derived from eight tobacco parents was developed. Eight 560 homozygous lines were genotyped by 430K single-nucleotide polymorphism (SNP) chip assay phenotyped nicotine content under different conditions. Four QTLs associated with detected genome-wide association (GWAS), one major QTL, named qNIC7-1,...
Agronomic traits such as plant height (PH), leaf number (LN), length (LL), and width (LW), which are closely related to yield quality, important in tobacco (Nicotiana tabacum L.). To identify quantitative trait loci (QTLs) associated with agronomic tobacco, 209 recombinant inbred lines (RILs) 537 multiparent advanced generation intercross (MAGIC) were developed. The biparental RIL MAGIC genotyped using a 430 K single-nucleotide polymorphism (SNP) chip assay, their repeatedly evaluated under...
Introduction Plant bacterial wilt is an important worldwide disease caused by Ralstonia solanacearum which a complex of species. Methods In this study, we identified and sequenced the genome R. strain gd-2 isolated from tobacco. Results Strain was as species (RSSC) phylotype I sequevar 15 exhibited strong pathogenicity to The size 5.93 Mb, including chromosomes (3.83 Mb) megaplasmid (2.10 Mb). Gene prediction results showed that 3,434 1,640 genes were in plasmids, respectively. Comparative...
Ralstonia solanacearum species complex (RSSC) is a diverse group of plant pathogens that attack wide range hosts and cause devastating losses worldwide. In this study, we conducted comprehensive analysis 131 RSSC strains to detect their genetic diversity, pathogenicity, evolution dynamics. Average nucleotide identity was performed explore the genomic relatedness among these strains, finally obtained an open pangenome with 32,961 gene families. To better understand also series analyses...
Abstract Background: At present, the distinctness, uniformity, and stability (DUS) testing of flue-cured tobacco ( Nicotiana tabacum L.) depends on field morphological identification, which is problematic in that it intensive, time-consuming, susceptible to environmental impacts. In order improve efficiency accuracy DUS testing, development a molecular marker-based method for genetic diversity identification urgently needed. Results: total, 91 simple sequence repeats (SSR) markers with clear...
Abstract Phenotypic plasticity is the property of a given genotype to produce multiple phenotypes in response changing environmental conditions. Understanding genetic basis phenotypic and establishing predictive model highly relevant for future agriculture under climate. Here, we investigated leaf width tobacco MAGIC population across four different environments. Environmental changes not only resulted differences mean but also plasticity. A total 45 QTL were identified, including 14 43...
Solanesol, which accumulates predominantly in the leaves of tobacco plants, has medically important bioactive properties. To investigate genetic basis solanesol (Nicotiana tabacum), contents 222 accessions, 206 individuals from an N. tabacum Maryland609 (low-solanesol) × K326 (high-solanesol) F2 population and their corresponding F1 self-pollinations, were determined using ultra-performance liquid chromatography. Genome-wide quantitative trait locus (QTL) association analysis performed to...
TOBAMOVIRUS MULTIPLICATION 1 (TOM1) and its homolog 3 (TOM3) play a prominent role in the multiplication of tobacco mosaic virus (TMV) higher plants. Although homologs NtTOM1/TOM3 genes have been identified several plant species, little is known about characteristics functions at genome-wide level (Nicotiana tabacum L.).
