Popularly known as "agroinoculation," this method has revolutionized plant virology studies, leading to identification of viruses as casual agents of disease, viral genome …

To date, a large number of recessive resistance genes involved in plant-virus interactions have been cloned from several plant species, and all of them have the characteristics of eIFs, such as eIF2Bβ, eIF4E, eIF4G and their isoforms, which are listed in Table 1 (Truniger and Aranda, 2009; Shopan et al., 2017).These comprise 19 natural …

ABA has multifaceted roles in plant defence; on the one hand, it increases callose deposition on plasmodesmata (PD) and restricts cell-to-cell movement of viruses, such as TMV and Tobacco necrosis virus (TNV), whereas, on the other, it antagonizes the SA pathway and reduces resistance at local sites of infection by repressing HR induction ...

Consequently, cross-talk between the antagonistic SA and ABA pathways modulates plant responses at multiple levels. In this review, we summarize recent findings on the different roles of hormones in the regulation of plant-virus interactions, which are helping us to elucidate the fine tuning of viral and plant systems by hormones.

plant virus, any of a number of agents that can cause plant disease.Plant viruses are of considerable economic importance because many of them infect crop and ornamental plants. Numerous plant viruses are rodlike and can be extracted readily from plant tissue and crystallized. The majority of them lack the fatty membrane found in …

Author Summary Cytoplasmic RNA granules play a central role in mRNA metabolism both in animal and plant cells. Here we demonstrate that Potato Virus A (PVA)-encoded multifunctional protein HCpro induces RNA granules, which contain in addition to HCpro several plant RNA granule proteins. We have earlier described a potyvirus …

Plant virus nanoparticles (PVNPs) have inherent immune stimulatory ability, and have been investigated as immune adjuvants to stimulate an anti-tumor immune response. The combination of immune stimulation, nanoparticle structure and the ability to deliver other therapeutic molecules provides a flexible platform for cancer immunotherapy ...

FERTILIZER EQUIPMENT, SYSTEMS, & SUPPORT SERVICES. Founded in 1951 as the Fertilizer Engineering & Equipment Company, the name FEECO has become synonymous with fertilizer granulation expertise in every facet – from process development, to equipment design and fabrication, and even parts and service.

involving both granulation and compression techniques 1.1. Granulation Rate Processes Granulation is a complex process with several competing physical phenomena occurring in the granulation vessel, which lead ultimately to the formation of the granules. We will divide these phenomena into three groups of rate processes (figure 1-3): 1.

Plant viral diseases are the foremost threat to sustainable agriculture, leading to several billion dollars in losses every year. Many viruses infecting several …

The in vitro cell cultures of several insect vectors of plant viruses including leafhoppers, planthoppers, aphids, thrips, and whiteflies have been successfully employed to understand the functions of viral proteins and receptor-mediated endocytosis into vector cells. ... Granulation and other deteriorative changes in the inoculated cells were ...

CSIRO has been working on a dry granulation process, integrated with heat recovery, since 2002. It involves a rotary disc that atomizes molten slag to produce liquid droplets, which are rapidly …

Simultaneous detection of multiple viruses is frequent in both healthy children 9 and children with respiratory infections 9,10,11,12,13,14,15, and virus-virus interactions can be either ...

(A) Horizontal transmission of plant viruses is mediated by insects, humans, or contaminated agricultural tools.(B) Vertical transmission of plant viruses is accomplished through two main routes: embryo invasion via infected pollen or gametes (1-2), and direct infection of the seed embryo via virus movement (3) using virus-encoded …

This study provides compelling evidence that conditional interactions of plant viruses, plant genotypes and the environment modulate the outcome of symbiosis.

The operation of granulation plants is difficult, often a relative small fraction of the granules that leave the size enlargement unit are in the required size range. Therefore high recycle ratios are commonly found [1]. The recycle stream can be reduced to some extent by technology improvements; however any process disturbance may affect the ...

Based on evidence from both experimental and modelling studies, a schema was proposed showing how natural enemies of virus vectors can increase virus fitness …

Plant viruses mainly come in the form of single-stranded (ss) and double-stranded (ds) RNA viruses, as well as single-stranded and DNA-containing retroviruses . Due to a wide diversity of their genetic material, the reproductive cycle and life pattern often vary from virus to virus (Fig. 2A). Viruses are composed of a nucleic acid molecule and ...

The TVA style drum granulator is utilized in most modern granulation plants, but this wasn't always the case. Prior to the 1950's, the most common granulated fertilizer was superphosphate (SSP) [6]. Many of the original superphosphate batch operation plants were retrofitted to produce granulated products by making use of

Changing markets and business situations, stricter environmental requirements and legislation are all

PLANT VIRUS POPULATIONS AND THEIR STRUCTURE. The sheer mass and diversity of genomics studies now being produced has driven renewed interest in the application of the "population" as a …

The main factors driving virus emergence are: i) the agricultural systems based on monocrops with low genetic diversity and high plant density, which are more vulnerable to pathogens and pests; ii) world trade of plant material (germplasm and live plants) that moves viruses, hosts, and vectors to new regions and environments; iii) the …

Therefore, the physiological disorders are distinguished from plant diseases caused by plant pathogens (fungi, bacteria, and viruses) and animal herbivores (insects) (Schutzki and Cregg, 2007). Although the symptoms of physiological disorders may appear disease-like, they can usually be prevented by altering environmental conditions.

The genomics era has revolutionized studies of adaptive evolution by monitoring large numbers of loci throughout the genomes of many individuals. Ideally, the investigation of emergence in plant viruses requires examining the population dynamics of both virus and host, their interactions with each other, with other organisms and the …
