Reductase expression is a potential indicator of cellular pathology. Single-detection systems for reductases have been developed, however, the development dual-detection remain largely unexplored. We rationally designed dual-lock fluorescent probe that exhibited high signal-to-noise ratio with fluorescence Off-On response exclusively simultaneous activity two reductases, NTR and hNQO1, which are overexpressed in cancer hypoxia. The system comprised naphthalimide fluorophore control mediated...
Summary Rapid, large‐scale generation of a Ds transposant population was achieved using regeneration procedure involving tissue culture seed‐derived calli carrying Ac and inactive elements. In the F 2 progeny from genetic crosses between same starter lines, most produced an independent germinal transposition frequency 10–20%. Also, many elements underwent immobilization even though expressed. By comparison, in callus‐derived regenerated population, over 70% plants carried insertions,...
Vitis vinifera, the major grapevine species cultivated for wine production, is very susceptible to Erysiphe necator, causal agent of powdery mildew (PM). This obligate biotrophic fungal pathogen attacks both leaf and berry, greatly affecting yield quality. To investigate possible mechanisms nutrient acquisition by successful biotrophs, we characterized a candidate NITRATE TRANSPORTER1/PEPTIDE TRANSPORTER FAMILY (NPF, formerly NRT1/PTR) member, NFP3.2, that was up-regulated in E....
Abstract Streptomyces scabies is an economically important plant pathogen well-known for damaging root and tuber crops by causing scab lesions. Thaxtomin A the main causative agent responsible pathogenicity of S. cello-oligosaccharides are environmental triggers that induce production this phytotoxin. How sensed or transported in order to virulent behavior ? Here we report cellobiose cellotriose binding protein CebE MsiK, ATPase providing energy carbohydrates transport, protagonists...
Abstract Abscisic acid (ABA) is a plant hormone that regulates growth as well stress responses. In this study, we identified and characterized new Arabidopsis (Arabidopsis thaliana) protein, Nuclear Protein X1 (NPX1), which was up-regulated by treatment with exogenous ABA. Stomatal closure, seed germination, primary root are well-known ABA responses were less sensitive to in NPX1-overexpressing plants. plants more drought sensitive, the changes response due altered guard cell sensitivity...
Posttranscriptional/translational regulation of gene expression is mediated by diverse RNA binding proteins and plays an important role in development defense processes. Among the RNA-binding proteins, mammalian Pumilio family (Puf) acts as posttranscriptional translational repressors. An Arabidopsis Puf mutant, apum5 - D , was isolated during a T-DNA insertional mutant screen for mutants with reduced susceptibility to Cucumber mosaic virus (CMV) infection. Interestingly, CMV contained...
• In Cucumber mosaic virus (CMV) RNA replication, replicase-associated protein CMV 1a and RNA-dependent polymerase 2a are essential for formation of an active replicase complex on vacuolar membranes. To identify plant host factors involved in a yeast two-hybrid system was used with as bait. One the candidate genes encoded Tsi1-interacting 1 (Tsip1), zinc (Zn) finger protein. Tsip1 strongly interacted protein, too. Formation involving or confirmed vitro planta. When 35S::Tsip1 tobacco...
In this study we investigated the antidiabetic and antiobesity effects of aqueous ethanol extracts traditional kochujang doenjang. The average α-glucosidase inhibitory activity adipogenesis for samples were 29.6% 20.8%, respectively, while those doenjang 46.3% 11.6%, respectively. Therefore, is high in kochujang. Kochujang components responsible suppressing functional by metabolomic analysis. For kochujang, p-coumaric acid, N6,N6,N6-trimethyllysine, threonine, methionine positively...
Many aspects of epigenetic phenomena have been elucidated via studies transposable elements. An active element frequently loses its ability to mobilize and goes into an inactive state during development. In this study, we describe the cyclic activity a maize dissociation (Ds) in rice. rice genome, Ds undergoes spontaneous loss mobility. However, can be changed tissue culture. The recovery mobility accompanies not only changes methylation patterns terminal region Ds, but also alteration...
The feasibility of incorporating jujube powder as a value-added food ingredient in cookies was investigated. amount added (0~20%) found to have significantly affected the cookie quality (p<0.05). Furthermore, pH ranged from 6.16 6.69, and moisture content gradually increased 4.11% 4.76%, while spread ratio loss rate decreased with increasing levels Lightness decreased; however, redness yellowness, well hardness, higher formulation In addition, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical...
Nonsteroidal anti-inflammatory drugs (NSAIDs) are well-known for exerting numerous adverse effects on the gastrointestinal tract such as bleeding, ulceration, and perforation, thereby limiting their use. Most previous studies have focused NSAID-induced gastropathy. However, improved diagnostic techniques recently highlighted small intestinal ulcers, which so far been underestimated. While proton pump inhibitors prescribed to control gastropathy, few preventive strategies existent injury,...
Abstract Background and Objectives This study investigated the effect of using different phenolic‐containing grain brans on nanoparticle properties. Findings successfully synthesized nanoparticles from bran flour isolated three sources: sorghum (Sumac Burgundy) hard red winter wheat (cv. 1863). The phenolic contents were measured as 33.40, 4.98, 1.59 mg GAE/g, respectively. NPs had content measuring 6.41 (sorghum‐Sumac bran), 5.31 (sorghum‐Burgundy 1.15 GAE/g (wheat bran). Adding gold to...
Silage is a high-moisture-content forage that used to feed livestock. Using silage as economically feasible and suitable for cattle management. Secale cereale considered high-quality plant. After the heading stage biomass of S. increases by up 30%; however, lignification in cell wall causes low fermentation efficiency coefficient digestibility, it may also be contaminated mycotoxin-producing fungi can impair quality silage. Therefore, aim this study was screen beneficial Lactobacillius spp....
Sakuranetin (SKN), found in cherry trees and rice, is a flavanone with various pharmacological activities. It biosynthesized from naringenin rice or trees, the metabolism of SKN has been studied non-human species. The present study aimed to investigate metabolic pathways human liver microsomes identify phase I II metabolites, as well evaluate potential for drug⁻herb interactions through modulation drug metabolizing enzymes (DMEs). HPLC-DAD HPLC-electrospray mass spectrometry were used...
The oral cavity is the second-largest habitat for microorganisms, and a well-balanced microbiome contributes to preventing dental disorders caused by pathogenic bacteria. Since humans dogs have different lifestyles structures, present study aimed develop novel probiotics dogs. A total 53 Lactobacillus spp. were isolated from healthy dogs, nine isolates identified as acidophilus according 16S rRNA gene sequencing. According high antimicrobial activity against caries-causing bacterium...
GC-NPD와 GC-ECD를 사용하여 잔류농약을 신속하게 정량 할 수 있는 변형 된 QuEChERS법이 시금치를 이용하여 검토되었다. 본 연구에서는 잔류농약 모니터링에서 주로 검출되며 GC로 측정 가능한 50가지 농약을 대상으로 하였다. 무농약 검량선을 작성하였으며, R2 값은 0.995 이상으로 모든 농약이 직선상을 나타내었다. 분석 농약의 검출한계는 0.001~0.1 ug/g로 나타났으며, 분석농약의 90% 이상이 0.05 ug/g 이하를 정량한계는 0.001~0.32 ug/g로, 이는 잔류 허용기준치 보다 낮았다. Dichlorvos, propamocarb, chlorothalonil, dichlofluanid, cyhalothrin 그리고 fenvalerate를 제외하고는 대부분의 경우 회수율은 80~120%, RSD는 20% 이하로 나타났다. QuEChers는 기존 다중분석법과 비교해볼 때 일상적인 시료에 응용했을 용매 사용량을 획기적으로 줄임으로써 친환경적 일뿐만...
본 연구는 식물 공장에서 특정 파장을 조합한 혼합 LED를 광원으로 사용하여 방울토마토와 적채를 재배할 때 식물의 성장과 각각에 존재하는 생리활성물질인 리코펜과 안토시아닌의 함량 변화를 탐색하였다. 대조광으로 형광등을 사용하였고 LED 파장은 적색, 녹황색, 청색 파장(630 nm:550 nm:450 nm=8:1:1)을 혼합하여 적채에 조사하였다. 방울토마토에서는 LED을 조사하였을 때, 수확되는 방울토마토의 개수는 적었으나 수확된 무게와 당도에서 유의적으로 높은 값을 나타내었다. 그러나 생리활성 물질인 리코펜의 함량은 조사 시 오히려 낮았다. 적채는 형광등에 비해 적체의 무게에서 나타내었고, 안토시아닌 또한 증가시켰다. 결론적으로 작물의 색에 따라 성장에 요구하는 LED의 파장 및 비율이 다르다는 것을 알았고, 과실의 파장의 비율을 달리하는 것이 필요하다는 보여주었다. Light emitting diodes (LED) are able to selectively control...
