Abstract Brown planthopper (BPH) is a phloem sap-sucking insect pest of rice which causes severe yield loss. We cloned the BPH18 gene from BPH-resistant introgression line derived wild species Oryza australiensis . Map-based cloning and complementation test revealed that encodes CC-NBS-NBS-LRR protein. has two NBS domains, unlike typical NBS-LRR proteins. The promoter:: GUS transgenic plants exhibited strong expression in vascular bundles leaf sheath, especially cells where BPH attacks....
The legume-rhizobium symbiosis is initiated through the activation of Nodulation (Nod) factor-signaling cascade, leading to a rapid reprogramming host cell developmental pathways. In this work, we combine transcriptome sequencing with molecular genetics and network analysis quantify categorize transcriptional changes occurring in roots Medicago truncatula from minutes days after inoculation Sinorhizobium medicae. To identify nature inductive regulatory cues, employed mutants absent or...
Rice is a source of food for the majority global population. Currently, rice yield declining owing to extreme climate change. Farmers use nitrogen fertilizers increase yield; however, excessive fertilizer application has negative impact on plants and environment. Nitrogen necessary growth rice, but it an important cause environ-mental pollution. Carbon monoxide (CO) emitted from fields due reacts with greenhouse gases such as carbon dioxide or methane, affecting warming. Although CO does not...
Plants have evolved strategies to cope with drought stress by maximizing physiological capacity and adjusting developmental processes such as flowering time. The WOX13 orthologous group is the most conserved among clade of WOX homeodomain-containing proteins found function in both flower development. In this study, we isolated characterized
Although susceptibility to seed shattering causes severe yield loss during cereal crop harvest, it is an adaptive trait for dispersal in wild plants. We previously identified a recessive locus, sh-h, from the rice mutant line Hsh that carries enhanced abscission layer. Here, we further mapped sh-h 34-kb region on chromosome 7 by analyzing 240 F(2) plants and five F(3) lines cross between Blue&Gundil. had point mutation at 3' splice site of seventh intron within LOC_Os07g10690, causing 15-bp...
Plant growth must be regulated throughout the plant life cycle. The myeloblastosis (MYB) transcription factor (TF) family is one of largest TF families and involved in metabolism, lignin biosynthesis, developmental processes. Here, we showed that OsMYB14, a rice R2R3-MYB TF, was expressed leaves roots, especially culm panicles, it localized to nucleus. Overexpression OsMYB14 (OsMYB14-ox) resulted 30% reduction height compared wild type (WT), while osmyb14-knockout (osmyb14-ko) mutant...
Abstract Phenotyping of rice (Oryza sativa L. cv. Donggin) in salt stress environment using infrared imaging was conducted. Results were correlated with the most frequently used physiological parameters such as stomatal conductance, relative water content and photosynthetic parameters. It observed that conductance (R 2 = -0.618) -0.852) significantly negatively average plant temperature (thermal images), while dark-adapted quantum yield (F v /F m , R -0.325) performance index -0.315) not...
Plant senescence is the process of physiological maturation plants and important for crop yield quality. Senescence controlled by several factors, such as temperature photoperiod. However, molecular basis which these genes promote in soybeans not well understood. We identified senescence-related via transcriptome analysis early-senescence (ES)- late-senescence (LS)-type to elucidate mechanisms soybeans. obtained F7 from a cross between hybrid (Glycine max × Glycine soja) cultivar. The...
Anther culture has advantage to obtain a homozygous progeny by induced doubling of haploid chromosomes and improve selection efficiency for invaluable agronomical traits. Therefore, anther culturing is widely utilized breed new varieties induce genetic variations in several crops including rice. Genome sequencing technologies allow the detection massive number DNA polymorphism such as SNPs Indels between closely related cultivars. These polymorphisms permit rapid identification diversity...
Foods rich in resistant starch can help prevent various diseases, including diabetes, colon cancers, diarrhea, and chronic renal hepatic diseases. Variations biosynthesis enzymes could contribute to the high content of some cultivars rice (Oryza sativa L.). Our previously published work indicated that sbe3-rs gene mutant line, 'Jiangtangdao1' was a putative allele branching enzyme SBEIIb (previously known as SBE3); might control line. Biomolecular analysis showed activity SBEs significantly...
Abstract Low temperature affects a broad spectrum of cellular components in plants, such as chloroplasts, well plant metabolism. On the other hand, pseudouridine (Ψ) synthases are required for most abundant post-transcriptional modification RNA Escherichia coli . However, role rice Ψ regulating chloroplast development at low remains elusive. In this study, we identified thermo-sensitive chlorophyll-deficient ( tcd3 ) mutant, which displays an albino phenotype before 4-leaf stage and...
Overexpression of abscisic acid (ABA) receptors has been reported to enhance drought tolerance, but also cause stunted growth and decreased crop yield. Here, we constructed transgenic rice for all monomeric ABA observed that only over-expressing OsPYL/RCAR7 showed similar phenotype with wild type, without total yield loss when grown under normal condition in a paddy field. Even though neither an ABA-sensitivity nor osmotic stress tolerance plate assay, it tolerance. We investigated the...
Rice is one of the most important food crops for humans. To improve agronomical traits rice, functions more than 1,000 rice genes have been recently characterized and summarized. The completed, map-based sequence genome has significantly accelerated functional characterization genes, but progress remains limited in assigning to all predicted non-transposable element (non-TE) estimated number 37,000–41,000. International Functional Genomics Consortium (IRFGC) generated a huge gene-indexed...
In plants, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a main enzyme in the glycolytic pathway. It plays an essential role glycerolipid metabolism and response to various stresses. To examine function of PsGAPDH (Pleurotus sajor-caju GAPDH) abiotic stress, we generated transgenic rice plants with single-copy/intergenic/homozygous overexpression (PsGAPDH-OX) investigated their responses salinity stress. Seedling growth germination rates PsGAPDH-OX were significantly increased under...
Rice field art is a large-scale form in which people design rice fields using various kinds of ornamental plants with different leaf colors. Leaf color-related genes play an important role the study chlorophyll biosynthesis, chloroplast structure and function, anthocyanin biosynthesis. Despite metabolites traditional relationship between color, comprehensive color-specific metabolite studies have been limited. We performed whole-genome resequencing transcriptomic analysis regulatory patterns...
Betaine aldehyde dehydrogenase 1 (BADH1), a paralog of the fragrance gene BADH2, is known to be associated with salt stress through accumulation synthesized glycine betaine (GB), which involved in response abiotic stresses. Despite unclear association between BADH1 and stress, we observed responses eight phenotypic characteristics (germination percentage (GP), germination energy (GE), index (GI), mean time (MGT), rate (GR), shoot length (SL), root (RL), total dry weight (TDW)) during stage...
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...
Chemical pesticides are still frequently overused to diminish such crop loss caused by biotic stress despite the threat humans and environment. Thus, it is urgent find safer more effective defense strategies. In this study, we report that caffeine, implanted through a transgenic approach, enhances resistance against variable stresses in rice without fitness cost. Caffeine-producing (CPR) was generated introducing three N-methyltransferase genes involved biosynthesis of caffeine coffee...
