Honey bees are eusocial insects that are commercially managed to provide pollination services for agricultural crops. Recent increased losses of honey bee colonies (averaging 32% annually since 2006) are associated with the incidence and abundance of pathogens. In their study in mBio, J. L. Li et al. [mBio 5(1):e00898-13, 2014, doi:10.1128/mBio.00898-13] share their discovery that a plant virus...

infection status of soybean field to tobacco ringspot virus (trsv) in golestan provincein order to serological detection of tobacco ringspot virus in soybean fields of golestan province, during 2008 growing season, infected samples of dpx, gorgan3, williams, pershing and jk cultivars with leaf malformation, stunting, necrosis and terminal bud blight symptoms, were collected and tested by enzyme...

Tomato ringspot virus (ToRSV), Tobacco ringspot virus (TRSV) and Tobacco rattle virus (TRV) are transmitted to healthy plants by viruliferous nematodes in the soil. A method was developed for extraction of genomic viral RNA from virus particles carried within nematodes and a sensitive nested RT-PCR detection assay. The procedure has been adapted to microscale for handling multiple samples. This...

Several viruses can cause devastating diseases in domestic apple (Malus x domestica Brokh.). Major viruses affecting apple production in New York are apple chlorotic leaf spot virus (ACLSV), apple stem pitting virus (ASPV), apple stem grooving virus (ASGV). These viruses are common and generally latent; in other words, they do not cause acute symptoms on most commercial cultivars. However, when...

The level 2 BLAS operation trsv performs a dense triangular solve, and is often used in the solve phase of a direct solver following a matrix factorization. With the advent of manycore architectures the importance of this memory-bound kernel is increasingly important, particularly for sparse direct solvers used in optimization applications. In this paper, a high performance implementation of th...

Diagnostic of 12 viral pathogens stone fruit crops, including new to the certification scheme ( Carnation ringspot tombusvirus (CRSV), Myrobalan latent nepovirus (MLRSV), Petunia asteroid mosaic (PeAMV) , Tobacco (TRSV )) by immune-enzyme analysis was carried out in Institute for growing 2020 – 2021. Virus-free clones varieties and rootstocks forms crops have been identified create Nuclear stoc...

During the last three years blackberries in southern and southeastern U.S. have shown symptoms of vein clearing, yellow mottling and plant decline with considerable variation in symptoms with cultivars. We isolated dsRNA from symptomatic plants and identified high molecular weight bands similar to those isolated from plants infected with criniviruses. Paired extractions from virus-tested blackb...
