A new imaging platform was constructed to analyze drought-tolerant traits of rice. Rice used quantify drought phenotypes through image-based parameters and analyzing tools. Climate change has increased the frequency severity drought, which limits crop production worldwide. Developing cultivars with tolerance short breeding cycles is critical. However, achieving this goal requires phenotyping a large number populations in time an accurate manner. Novel cutting-edge technologies such as those...

The soil-borne pathogenic Ralstonia solanacearum species complex (RSSC) is a group of plant pathogens that economically destructive worldwide and has broad host range, including various solanaceae plants, banana, ginger, sesame, clove. Previously, Korean RSSC strains isolated from samples potato bacterial wilt were grouped into four pathotypes based on virulence tests against potato, tomato, eggplant, pepper. In this study, we sequenced the genomes 25 selected these pathotypes. newly...
High-throughput molecular markers with high genotyping accuracy will be helpful for genetic analysis, mapping of interesting genes, and rice breeding program. To develop high-throughput cost-effective Korean japonica varieties, which are closely-related genetically, we designed kompetitive allele-specific polymerase chain reaction (KASP) assays from the sequence data 13 varieties. Of 504 new KASP assays, 371 (73.6%) showed polymorphisms among tested In addition to 400 previously developed...
The development of efficient, robust, and high-throughput SNP genotyping platforms is pivotal for crop genetics breeding. Recently, based on target capture sequencing, which very flexible in terms the number markers, have been developed maize, cassava, fava bean. We aimed to develop a sequencing platform rice. A panel containing 2565 SNPs, including 1225 SNPs informative japonica 1339 indica, was developed. This used diversity analysis 50 rice varieties. Of 2341 (91.3%) produced useful...
Platycodon grandiflorus (balloon flower) and Codonopsis lanceolata (bonnet bellflower) are important herbs used in Asian traditional medicine, both belong to the botanical family Campanulaceae. In this study, we designed implemented a de novo DNA sequencing assembly strategy map complete mitochondrial genomes of first two members Campanulaceae using low-coverage Illumina data. We produced total 28.9 Gb paired-end data from genomic P. (20.9 Gb) C. (8.0 Gb). The assembled genome was found...
Abstract Pre-harvest sprouting (PHS) leads to serious economic losses because of reductions in yield and quality. To analyze the quantitative trait loci (QTLs) for PHS resistance japonica rice, rates on panicles were measured 160 recombinant inbred lines (RILs) derived from a cross between temperate varieties Odae (PHS resistant) Unbong40 susceptible) under two different environmental conditions—field (summer) greenhouse (winter) environments. Genome re-sequencing parental detected 266,773...
Temperate japonica rice varieties exhibit wide variation in the phenotypes of several important agronomic traits, including disease resistance, pre-harvest sprouting plant architecture, and grain quality, indicating presence genes contributing to favorable traits. However, gene mapping molecular breeding has been hampered as a result low genetic diversity among cultivars scarcity polymorphic DNA markers. Single nucleotide polymorphism (SNP)-based kompetitive allele-specific PCR (KASP)...
Next-generation sequencing technologies have enabled the discovery of numerous sequence variations among closely related crop varieties. We analyzed genome resequencing data from 24 Korean temperate japonica rice varieties and discovered 954,233 variations, including 791,121 single nucleotide polymorphisms (SNPs) 163,112 insertions/deletions (InDels). On average, there was one variant per 391 base-pairs (bp), a density 2.6 1 kbp. Of InDels, 10,860 were longer than 20 bp, which conversion to...
Drought is being annually exacerbated by recent global warming, leading to crucial damage of crop growth and final yields. Soybean, one the most consumed crops worldwide, has also been affected in process. The development a resistant cultivar required solve this problem, which considered efficient method for producers. To accelerate breeding cycles, genetic engineering high-throughput phenotyping technologies have replaced conventional methods. However, current novel still needs be optimized...
Internode elongation is an important agronomic trait in rice that determines culm length, which related to lodging, panicle exsertion, and biomass. sui4 (shortened uppermost internode 4) mutants show reduced length a dwarf phenotype due shortened internodes; the particularly severely affected. The present study was performed identify molecular nature function of SUI4 gene during elongation.Our previous showed mapped 1.1-Mb interval on chromosome 7 (Ji et al. 2014). In order isolate...
Information on multiple synteny between plants and/or within a plant is key information to understand genome evolution. In addition, visualization of helpful in interpreting So far, some web applications have been developed determine and visualize homology regions at once. However, the are not fully convenient for biologists because them do include function determination but plots by allowing users upload their data determining based only BLAST similarity information, with algorithms...
The KIX domain, conserved among various nuclear and co-activator factors, acts as a binding site that interacts with other transcriptional activators co-activators, playing crucial role in gene expression regulation.
