باقلا (vicia faba l.) یکی از حبوبات مهم در بسیاری از کشورها به شمار می¬رود و بهعنوان منبع پروتئینی بهمنظور تغذیه¬ انسان، دام و طیور مورد استفاده قرار گرفته و در تثبیت نیتروژن و کمک به امنیت غذایی از اهمیت ویژهای برخوردار است. عارضه¬ای مشکوک به بیماری ویروسی با علائم موزائیک، پیچیدگی و بدشکلی برگ باقلا سالهای متمادی در مزارع باقلای استان خوزستان مشاهده شده است. از اینرو هدف از انجام این پژو...
Mosaic View is a mosaic picture composed of small pieces that contain images. The images used for the pieces can be arbitrary, so the overall image depicted in the mosaic can be independent of the images constituting the parts. The mosaic can display a modest overall image containing rich information using many small images. This article describe one method for making a mosaic, as well as sever...
Small interfering (si)RNAs isolated from Brassica juncea leaves infected by Turnip mosaic virus (TuMV) were characterized by cloning and sequencing. The TuMV siRNA population was dominated by 21 and 22-nt long species originated mainly from the same siRNA hotspots, indicating operational similarity between the plant Dicer-like (DCL) enzymes. Robust GC bias was observed for TuMV siRNAs versus th...
Complete Genome Sequence of Alternanthera mosaic virus, Isolated from Achyranthes bidentata in Asia.
Alternanthera mosaic virus (AltMV) infecting Achyranthes bidentata was first detected in Asia, and the complete genome sequence (6,604 nucleotides) was determined. Sequence identity analysis and phylogenetic analysis confirmed that this isolate is the most phylogenetically distant AltMV isolate worldwide.
Synthesis and antiviral bioactivity of chiral thioureas containing leucine and phosphonate moieties.
A series of novel chiral thioureas 3a-n bearing leucine and phosphonate moieties were synthesized in excellent yields. The structures of the compounds were completely characterized by elemental analysis, IR, 1H-, 13C-, 31P- and 19F-NMR spectral data. A half-leaf method was used to determine the in vivo protective and curative efficacies of the title products against tobacco mosaic virus (TMV). ...
Phenotypic expression of different genes controlling resistance to tobacco mosaic virus (TMV) in tomato was analysed in the protoplast system using otherwise isogenic breeding lines. Genes Tm-2 and Tin-22 were not expressed and did not prevent TMV-L, a common tomato strain of TMV, infecting and multiplying. By contrast, homozygous gene Tin-I was able to express its effect in protoplasts as well...
In this paper, the geometric relationship between mosaic images for concentric panorama acquired by slit cameras along circular paths is considered. A concentric epipolar constraint is derived for mosaic images. It is shown how the concentric epipolar constraint can be used to calibrate the slit camera using point correspondences in two mosaic images. The concentric epipolar constraint is furth...
Interstrain recombinants were observed in the progenies of the Cucumber mosaic virus (CMV) reassortant L(1)L(2)F(3) containing RNAs 1 and 2 from LS-CMV and RNA 3 from Fny-CMV. We characterized these recombinants, and we found that their fixation was controlled by the nature of the replicating RNAs 1 and 2. We demonstrate that the 2b gene partially affects this fixation process, but only in the ...
Determination of the structure of biological particles, randomly oriented in solution, from spatial correlation analysis of fluctuations in x-ray scattering has recently been proposed. The feasibility of scattering fluctuation measurements was evaluated by using an x-ray synchrotron radiation camera to obtain the spatial correlation for a solution of tobacco mosaic virus along a line. The exper...
