It has been shown that virus infections, often symptomless, significantly limit sweetpotato productivity, especially in regions characterized by low input agricultural systems. In sweetpotatoes, the successful emergence and development of lateral roots (LRs), the main determinant of root architecture, determines the competency of adventitious roots to undergo storage root initiation. This study...

Sweet potato has been identified as a crop that has great potential for alleviating food security concerns (28). However, because it is vegetatively propagated, it is prone to accumulate viruses and other pathogens. Sweet potato viruses are difficult to transmit mechanically, they occur in mixed infections, and their host range often is restricted to the family Convolvulaceae (24). These factor...

Mitogen-activated protein kinase (MAPK) cascades have crucial roles in the regulation of plant development and in plant responses to stress. Plant recognition of pathogen-associated molecular patterns or pathogen-derived effector proteins has been shown to trigger activation of several MAPKs. This then controls defence responses, including synthesis and/or signalling of defence hormones and act...

turnip curly top virus (tctv) is a member of the newly established genus turncurtovirus, family geminiviridae. development of an efficient detection system is necessary to study the biological characteristics of viruses. due to the superior efficacy of the serological methods for detection of plant viruses, in this research, with the aim to facilitate the process of immunological detection of t...

OBJECTIVES Hepatitis C virus (HCV) infection causes chronic liver disease and is a major public health problem worldwide. The aim of this study was to evaluate the potential of Monascus pigment derivatives, which were derived from a microbial secondary metabolite synthesized from polyketides by Monascus spp., as HCV antiviral agents. METHODS We performed an in vitro RNA-dependent RNA polymera...

A molecular probe, p3POT, was constructed of PSTVd, PVY, PLRV cDNA fragments introduced into pUC18 vector. Sequencing of the inserts revealed that cloned fragments covered conservative parts of pathogenic genomes. Dot-blot hybridization of digoxigenin-labelled construct to crude extracts from plants infected with different potato viruses proved high sensitivity and specificity of the p3POT prob...

Microblogging services have become popular, especially since smartphones made them easily accessible for common users. However, current services like Twitter rely on a centralized infrastructure, which has serious drawbacks from privacy and reliability perspectives. In this paper, we present a decentralized privacy-preserving microblogging infrastructure based on a distributed peer-to-peer netw...

In Brazil, Potyvirus species in sweet potatoes have been detected mostly by serology. Here, we report the complete genome sequences of two Potyvirus species, Sweet potato feathery mottle virus strain (SPFMV-UNB-01) and Sweet potato virus G strain (SPVG-UNB-01).

abstract: potato virus y a type species of the genus potyvirus infects several crops in the family solanaceae. pvy isolated from field infected peppers was identified on the basis of host reaction, serological and molecular characterization. the result of elisa, immunoblot electrophoresis and immuno capture reverse transcription polymerase chain reaction   (ic-rt-pcr) indicated that pepper isol...
