Summary Plants possess hundreds of intracellular immune receptors encoding nucleotide‐binding domain leucine‐rich repeat (NLR) proteins. Full‐length NLRs or a specific often induce plant cell death in the absence pathogen infection. In this study we used genome‐wide transient expression analysis to identify group (ANLs; ancient and autonomous NLRs) carrying autoactive coiled‐coil (CC A ) domains pepper ( Capsicum annuum ). CC ‐mediated mimics hypersensitive triggered by interaction between...
The onion (Allium cepa L.) is one of the most widely cultivated and consumed vegetable crops in world. Although a considerable amount transcriptome data has been deposited into public databases, sequences protein-coding genes are not accurate enough to be used, owing non-coding intermixed with coding sequences. We generated high-quality, annotated from de novo sequence assembly intensive structural annotation using integrated gene pipeline (ISGAP), which identified 54,165 among 165,179...

Accessions intensively collected from Korea, which small but central region in geography soybean, genotyped provide sufficient underpin population genetic questions. After...
Summary Nonhost resistance ( NHR ) is a plant immune response to resist most pathogens. The molecular basis of poorly understood, but recognition pathogen effectors by receptors, known as effector‐triggered immunity, has been proposed component . We performed transient expression 54 Phytophthora infestans RXLR in pepper Capsicum annuum accessions. used optimized heterologous methods and analyzed the inheritance effector‐induced cell death an F 2 population derived from cross between two...
Hibiscus syriacus (L.) (rose of Sharon) is one the most widespread garden shrubs in world. We report a draft H. genome comprised 1.75 Gb assembly that covers 92% with only 1.7% (33 Mb) gap sequences. Predicted gene modeling detected 87,603 genes, mostly supported by deep RNA sequencing data. To define family distribution among relatives syriacus, orthologous sets containing 164,660 genes 21,472 clusters were identified OrthoMCL analysis five plant species, including Arabidopsis thaliana,...
Summary Nonhost resistance (NHR) is a robust plant immune response against non‐adapted pathogens. A number of nucleotide‐binding leucine‐rich repeat (NLR) proteins that recognize pathogens have been identified, although the underlying molecular mechanisms driving robustness NHR are still unknown. Here, we screened 57 effectors potato late blight pathogen Phytophthora infestans in nonhost pepper ( Capsicum annuum ) to identify avirulence effector candidates. Selected were tested 436...
Pathogen effectors target diverse subcellular organelles to manipulate the plant immune system. Although nucleolus has emerged as a stress marker and several are localized in nucleolus, roles of nucleolar-targeted remain elusive. In this study, we showed that Phytophthora infestans infection Nicotiana benthamiana results nucleolar inflation during transition from biotrophic necrotrophic phase. Multiple P. were nucleolus: Pi23226 induced cell death N. similar observed stage infection, whereas...
Abstract Hot pepper ( Capsicum annuum ) is one of the most consumed vegetable crops in world and useful to human as it has many nutritional medicinal values. Genomic resources are publically available since genomes have been completed massive data such transcriptomes deposited. Nevertheless, global transcriptome profiling needed identify molecular mechanisms related agronomic traits pepper, but limited analyses published. Here, we report comprehensive analysis during fruit ripening pathogen...
During the evolution of land plants from aquatic to terrestrial environments, their aerial surfaces were surrounded by cuticle composed cutin and cuticular waxes protect them environmental stresses. Glycerol-3-phosphate acyltransferase (GPAT) harboring bifunctional sn-2 acyltransferase/phosphatase activity produces 2-monoacylglycerol, a precursor for synthesis. Here, we report that GPATs play roles in biosynthesis gametophore development Physcomitrella patens. Land plant-type was observed...
A Gram-negative micro-organism, designated strain B7(T), was isolated from tidal flat sediment and subjected to a polyphasic taxonomic study involving morphological, physiological, biochemical 16S rRNA gene sequence analyses. phylogenetic analysis based on the indicated that B7(T) belonged genus Paracoccus closely related phylogenetically marcusii MH1(T) (97.5 % similarity), marinus KKL-A5(T) %), haeundaensis BC74171(T) (97.3 carotinifaciens E-396(T) homiensis DD-R11(T) (97.2 seriniphilus...
Summary Whole‐genome annotation error that omits essential protein‐coding genes hinders further research. We developed Target Gene Family Finder ( TGFam‐Finder ), an alternative tool for the structural of containing target domain(s) interest in plant genomes. took considerably reduced run‐time and improved accuracy compared to conventional tools. Large‐scale re‐annotation 50 genomes identified average 150, 166 86 additional far‐red‐impaired response 1, nucleotide‐binding leucine‐rich‐repeat,...
Abstract Massive resequencing efforts have been undertaken to catalog allelic variants in major crop species including soybean, but the scope of information for genetic variation often depends on short sequence reads mapped extant reference genome. Additional de novo assembled genome sequences provide a unique opportunity explore dispensable fraction pan-genome species. Here, we report assembly and annotation Hwangkeum, popular soybean cultivar Korea. The was constructed using PromethION...
Peppers (Capsicum annuum L.) containing distinct capsaicinoids are the most widely cultivated spices in world. However, extreme genomic diversity among species represents an obstacle to breeding pepper.Here, we report de novo genome assemblies of Capsicum 'Early Calwonder (non-pungent, ECW)' and 'Small Fruit (pungent, SF)' along with their annotations.

NLR receptor is suggested as a component of plant nonhost resistance (NHR). However, the evolutionary process how plants develop receptors for recognizing broad-spectrum pathogens still elusive. Here, we observe that multiple RxLR effector families including 12 reported avirulence effectors Phytophthora infestans are broadly conserved across species. We select 69 distributed into 8 from 6 species, and confirm 60.87% tested recognized by Solanum NLRs according to their defined families....
Platycodon grandiflorum, generally known as the bellflower or balloon flower, is only species in genus of family Campanulaceae. plants have been traditionally used a medicinal crop East Asia for their antiphlogistic, antitussive, and expectorant properties. Despite these practical uses, marker-assisted selection molecular breeding platycodons lagged due to lack genetic information on this genus.
