Tomato yellow leaf curl virus (TYLCV) is one of the most well-known tomato-infecting begomoviruses and transmitted by Bemisia tabaci. Seed transmission has previously been reported for some RNA viruses, but TYLCV not described as a seed-borne virus. In 2013 2014, without whitefly-mediated transmission, was detected in young tomato plants germinated from fallen fruits produced TYLCV-infected previous cultivation season. addition, TYLCV-Israel (TYLCV-IL) also seeds their seedlings that were...
Multiwavelength Raman fiber lasers using intracavity tunable cascaded long-period gratings (LPFGs) are discussed. The application of the LPFGs as a multichannel filter for multiple-wavelength generation is proposed and experimentally demonstrated. characteristics multiwavelength fiber-ring can be controlled by changing physical parameters such separation distance between gratings, grating length, number gratings. laser with nine wavelength-division-multiplexing channels 100-GHz spacing 19...
Secretory leukocyte protease inhibitor (SLPI) protects tissue from proteases, and promotes cell proliferation healing during inflammatory response. SLPI is also overexpressed in gastric, lung ovarian cancers, which accelerates the metastasis of cancer cells. Matrix metalloproteinases-2, -9 (MMP-2 MMP-9) are high metastatic promote migration cells through collagen degradation. MMP-2, critical factors stimulating processes but there no reports a direct correlation between these molecules....
We propose and demonstrate a simple accurate optical fiber modal birefringence measurement technique based on two-segment Lyot-Sagnac interferometer. have conducted measurements for several low fibers the results are consistent with published data. This method is allowed in birefringence-length product ranging from 10/sup -3/ to -6/ m within resolution of spectrum analyzer used.
Tomato yellow leaf curl virus (TYLCV) infection of the common bean (Phaseolus vulgaris) has been reported, but soybean (Glycine max) not previously identified as a TYLCV host. Five cultivars white were agro-inoculated using an infectious clone. At 30 days post-inoculation, they showed rates 25% to 100%. Typical symptoms observed in any inoculated plants. To examine whether was transmitted seeds, DNA isolated from bundles five randomly selected seeds TYLCV-inoculated plants and amplified with...
We demonstrate a highly linearly wavenumber-swept active mode locking (AML) fiber laser in the 1.3 μm region for in-vivo imaging optical coherence tomography (OCT) without wavenumber space resampling. In this all-electric AML mechanism, conventional wavelength selection filter is eliminated, and instead suitable programmed electric modulation signal applied directly to gain medium. For high sweep rate (up 1 MHz) along wavenumber, cavity structure made as short possible (0.88 m air). A 15...
Prickly sow thistle, Sonchus asper (L.) Hill, and common oleraceus L., are noxious weeds. Probably originating from the Mediterranean region, they have become widespread species. They share similar morphology closely related. However, differ in their chromosome numbers precise relationship between them remains uncertain. Understanding chloroplast genome structure evolution is an important initial step toward determining phylogenetic relationships analyzing accelerating plant invasion...
Complete genome sequences of 22 isolates Cucurbit aphid-borne yellows virus (CABYV), collected from melon plants showing yellowing symptom in Korea during the years 2013-2014, were determined and compared with previously reported CABYV sequences. The complete genomes found to be 5,680-5,684 nucleotides length encode six open reading frames (ORFs) that are separated into two regions by a non-coding internal region (IR) 199 nucleotides. Their genomic organization is typical genus Polerovirus....

Tomato spotted wilt virus (TSWV) is one of the plant viruses transmitted by thrips and causes severe economic damage to various crops. From 2008 2011, identify natural host species TSWV in South Korea, weeds crops were collected from 5 regions (Seosan, Yesan, Yeonggwang, Naju, Suncheon) where occurred identified as 1,104 samples that belong 144 40 families. According reverse transcription-polymerase chain reaction, was detected 73 23 crop species, which belonged family Solanaceae....
A nationwide survey was performed to investigate the current incidence of viral diseases in Korean sweet potatoes for germplasm and growing fields from 2011 2014. total 83.8% Korea infected with viruses 2011. Commercial cultivars that were used supply at a rate 62.1% 2012. Among surveyed viruses, five Potyvirus species infect potato decreased between 2012 2013, then increased again Representatively, Sweet feathery mottle virus (SPFMV) 87.0% 2012, 20.7% 2013 35.3% Unlike RNA DNA shown...
