Comparative transcriptome analysis in Triticum aestivum infecting wheat dwarf virus reveals the effects of viral infection on phytohormone and photosynthesis metabolism pathways

Phytopathology Research, 2020
Wheat dwarf virus (WDV), a mastrevirus transmitted by the leafhopper Psammotettix alienus, causes a severe disease in cereal crops. Typical symptoms of wheat plants infected by WDV are yellowing and severe dwarfing.

Variation in susceptibility to Wheat dwarf virus among wild and domesticated wheat. [PDF]

PLoS ONE, 2015
We investigated the variation in plant response in host-pathogen interactions between wild (Aegilops spp., Triticum spp.) and domesticated wheat (Triticum spp.) and Wheat dwarf virus (WDV).

Temperature affected transmission, symptom development and accumulation of Wheat dwarf virus

Plant Protection Science, 2018
One of the biotic agents of yellowing and stunting in wheat and barley cultivations is Wheat dwarf virus (WDV) which is naturally transmitted by the leafhopper Psammotettix alienus (Dahlbom).

Thermodynamical Properties of Apparent Horizon in Warped DGP Braneworld [PDF]

, 2007
In this paper we first obtain Friedmann equations for the $(n-1)$-dimensional brane embedded in the $(n+1)$-dimensional bulk, with intrinsic curvature term of the brane included in the action (DGP model).

Unified First Law and Thermodynamics of Apparent Horizon in FRW Universe [PDF]

, 2007
In this paper we revisit the relation between the Friedmann equations and the first law of thermodynamics. We find that the unified first law firstly proposed by Hayward to treat the "outer"trapping horizon of dynamical black hole can be used to the ...

Functional Transcomplementation between Wheat Dwarf Virus Strains in Wheat and Barley

Viruses, 2019
Wheat dwarf virus, transmitted by the leafhopper Psammotettix alienus in a persistent, non-propagative manner, infects numerous species from the Poaceae family. Data associated with wheat dwarf virus (WDV) suggest that some isolates preferentially infect

Higher Bacterial Diversity of Gut Microbiota in Different Natural Populations of Leafhopper Vector Does Not Influence WDV Transmission

Frontiers in Microbiology, 2019
The bacterial communities in the gut of an insect have important ecological and functional effects on the insect. However, the community composition and diversity of the gut microbiota in insects that vector plant viruses are poorly understood.

Detection of barley- and wheat-specific forms of Wheat Dwarf Virus in it's vector Psammotettix alienus by duplex PCR assay

Journal of Plant Protection Research, 2018
Wheat dwarf virus (WDV) has been one of the most common viruses on cereal crops in Poland in the last years. This single stranded DNA virus is transmitted by the leafhopper spec, Psammotettix alienus (Dahlb.) in a persistent manner.

Fully parameterized macromodeling of S-parameter data by interpolation of numerator & denominator [PDF]

, 2012
A robust approach for parametric macromodeling of tabulated frequency responses is presented. An existing technique is modified in such a way that interpolation is performed at the numerator and denominator level, rather than the transfer function level.
