High-throughput deep-sequencing technology and bioinformatics analysis of the small RNA(sRNA) population isolated from plants allows universal virus detection and complete virome reconstruction for a given sample. In the present sRNA deep-sequencing analysis of virus-infected wheat samples in the Czech Republic, samples were firstly tested for barley yellow dwarf viruses(BYDVs), wheat streak mosaic virus(WSMV) and wheat dwarf virus(WDV) using ELISA, RT-PCR and PCR. Subsequent sRNA sequencing of these samples yielded more than ～60 million single-end 50-bp reads with high confidence for nine field samples of wheat. Overall, 16.5% of reads were virus-specific and 83.5% were mapped to the host. More 21-nt reads(～7.7 E+06 reads) were found than 24-nt(～6.20 E+06 reads) or 22-nt(～4.30 E+06 reads) reads. De novo assembly of the high-quality contigs revealed the presence of three earlier reported viruses in the Czech Republic: BYDVs(31.48%), WSMV(24.23%) and WDV(26.66%). We also showed the presence of cereal yellow dwarf virus(14.33%; two species CYDV-RPS and CYDV-RPV(family Luteoviridae/Polerovirus) and wheat yellow dwarf virus(WYDV, 3.30%; Luteoviridae). Phylogenetic analysis showed CYDV and WYDV grouped separately from BYDVs. Furthermore, several recombination breakpoints were found among the groups of yellow dwarf viruses(BYDVs, CYDV, and WYDV). Using RNA deep sequencing, we confirmed the presence of the three known viruses(BYDVs, WSMV, and WDV) and the first record of two species of CYDV and WYDV in wheat in the Czech Republic.  相似文献   

The Impact of Oat Quality on White Salted Noodles Containing Oat Flour     

Sabori Mitra  Anthony Paul James  Haelee Kim Fenton  Larisa Cato  Vicky Ann Solah 《Cereal Chemistry》2016,93(3):282-292

This research compared the physicochemical properties of six milling oat cultivars from Western Australia over two growing seasons (2011 and 2012). Variations among the cultivars in physicochemical properties, particularly β‐glucan content, were assessed to determine their suitability for incorporation into white salted noodles at a level of 30% of the flour component. The average across six oat cultivars grown in 2012 was significantly higher (P < 0.05) for protein content, lipid content, and volume of smaller sized particles (<100 µm) and significantly lower for ash content, starch damage, and volume of larger particles (>100 µm) in comparison with the average across the same oat cultivars grown in 2011. The year of cultivation by cultivar interaction was significant (P < 0.05) for ash content, protein content, β‐glucan content, starch damage, and particle size. Oat cultivar Mitika had the highest peak viscosity for 100% oat flour (whole groat) and 30% oat–wheat (OW) flour blend, which may be owing to lower amylose percentage, high protein content, and greater volume of smaller particles. The effect of growing season had greater impact on OW noodle firmness than the genetic effect of cultivars. The eating and cooking quality attributes of OW noodles, such as color, color stability, firmness, and cooking solid loss were superior for those incorporated with 2012 oat flour (whole groat) compared with 2011 oat flour. Among the six oat cultivars, Williams produced noodles with poor cooking and eating quality, and Mitika was easier to handle during processing and produced noodles with superior brightness and color stability in comparison with other oat cultivars evaluated.  相似文献   

Imaging of transient structures using nanosecond in situ TEM     

Kim JS  Lagrange T  Reed BW  Taheri ML  Armstrong MR  King WE  Browning ND  Campbell GH 《Science (New York, N.Y.)》2008,321(5895):1472-1475

The microstructure and properties of a material depend on dynamic processes such as defect motion, nucleation and growth, and phase transitions. Transmission electron microscopy (TEM) can spatially resolve these nanoscale phenomena but lacks the time resolution for direct observation. We used a photoemitted electron pulse to probe dynamic events with "snapshot" diffraction and imaging at 15-nanosecond resolution inside of a dynamic TEM. With the use of this capability, the moving reaction front of reactive nanolaminates is observed in situ. Time-resolved images and diffraction show a transient cellular morphology in a dynamically mixing, self-propagating reaction front, revealing brief phase separation during cooling, and thus provide insights into the mechanisms driving the self-propagating high-temperature synthesis.  相似文献   

The probable genome donors to Arachis hypogaea L. based on arachin seed storage protein     

T. G. Krishna  R. Mitra 《Euphytica》1988,37(1):47-52

Summary Interrelationships among six diploid species (A. chacoense, A. villosulicarpa, A. batizocoi, A. correntina, A. duranensis and A. cardenasii), tetraploid wild groundnut A. monticola and four accessions of A. hypogaea were studied by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) of total seed proteins and arachin immunoprecipitates. Arachin in A. monticola and A. hypogaea cv. Trombay Groundnut 9 (TG-9) was composed of four acidic subunits (47.5 kd, 45.1 kd, 42.6 kd and 41.2 kd) and one major basic subunit (21.4 kd). The arachin subunit pattern in cv. Spanish Improved (SP) and TG-1 was almost similar to the pattern observed in A. monticola with the exception that the SP lacked the 41.2 kd and TG-1 lacked the 42.6 kd acidic subunits of A. monticola. Seed extracts of all diploid species studied reacted with the anti-arachin antibodies raised against SP arachin. The electrophoretic analysis of immunoprecipitates of diploid species showed a range of acidic subunits from 46.2 kd to 41.2 kd and one or two basic subunits of 21.4 kd and 20.2 kd. None of the diploid species showed the 47.5 kd subunit found in A. monticola or A. hypogaea. Of the diploid species, A. duranensis and A. cardenasii demonstrated two acidic subunits of 45.1 kd and 41.2 kd and a basic subunit of 21.4 kd as found in A. monticola. Likewise A. batizocoi showed two acidic subunits of 45.1 kd and 42.6 kd and the basic subunit of 21.4 kd as was observed in A. monticola. Based on electrophoretic data, our research supports the earlier conclusion that the probable genome donors to A. monticola are A. batizocoi and A. duranensis or A. cardenasii.  相似文献

Effects of aflatoxin on the growth performance and immune responses of weanling swine   总被引：2，自引：0，他引：2

Aflatoxin (AF)-contaminated ground corn was mixed with a commercial swine ration to yield 2 concentrations (500 mg of AFB1/kg of feed [A] and 300 mg of AFB1/kg [B]) and was fed to 2 groups of pigs. Groups A and B were fed the AF-containing ration, whereas control group C was fed the same commercial ration mixed with ground corn devoid of AF. A comparative analysis of the average weight gain per pig in each of the treatment groups, compared with that in the control group, indicated a significantly (P less than 0.01) greater weight gain in the control group. The average feed conversion rate was also significantly (P less than 0.01) lower in group A pigs, compared with that in the control group. The humoral immune response to Erysipelothrix rhusiopathiae, measured by enzyme-linked immunosorbent assay, did not reveal a significant difference among groups; there were no consistent differences observed in the proliferative responses of lymphocytes to mitogens. In contrast, a significant (P less than 0.05) reduction in complement titers was observed, whereas an increase in serum immunoglobulin G and M values occurred in the AF-treated group A, compared with that in group C. Gross enlargement of the liver, substantiated by histologic evidence of toxic damage to the hepatic parenchyma, revealed that AF at concentrations of 500 mg/kg of feed was toxigenic and produced an adverse effect on the growth rate, feed efficiency, and general well-being of young pigs.  相似文献

Bioenergetic and energy constraints in increasing cereal productivity     

C.R. Bhatia  R. Mitra  R. Rabson 《Agricultural Systems》1981,7(2):105-111

The grain yield potential of cereal crops such as wheat, rice, barley, oats and sorghum has increased by genetic improvement in the harvest index (grain yield/biological yield). Such alterations in the harvest index were analysed from the point of view of intrinsic energy and nitrogen, phosphorus and potassium requirements. A higher harvest index, without any reduction in biological yield, increases the harvest of: (a) energy (MJ) in the above ground parts of the crop and (b) nitrogen and phosphorus in the grain. In addition, it enhances the fertiliser requirement of the crop. From bioenergetic considerations, higher grain yields, obtained by improving the harvest index, represent a path which demands least increments in photosynthate and nutrient inputs. The other alternatives available for increasing cereal productivity, once the upper limits of the harvest index are reached by breeding, have higher costs in terms of photosynthate and fertiliser requirements (energy inputs). There seems to be no other immediate plant breeding alternative to increase productivity without additional energy (fertiliser) inputs.  相似文献
