Genomic Analysis of the Natural Population of Wheat dwarf virus in Wheat from China and Hungary

open access: yesJournal of Integrative Agriculture, 2012
During the last decade, the leafhopper transmitted Wheat dwarf virus (WDV) has become a serious problem both in northwestern China and Hungary. In order to study the molecular diversity and population structure of WDV in these two countries, 39 Chinese ...

Two mutations in the truncated Rep gene RBR domain delayed the Wheat dwarf virus infection in transgenic barley plants

open access: yesJournal of Integrative Agriculture, 2018
Wheat dwarf virus (WDV), an important cereal pathogen, is closely related to Maize streak virus (MSV), a model virus of the Mastrevirus genus. Based on its similarity to known MSV resistance strategies, a truncated part of the WDV replication-associated (

The Chiral Ring and the Periods of the Resolvent [PDF]

open access: yes, 2007
The strongly coupled vacua of an N=1 supersymmetric gauge theory can be described by imposing quantization conditions on the periods of the gauge theory resolvent, or equivalently by imposing factorization conditions on the associated N=2 Seiberg-Witten ...

Nonleptonic Cabibbo Favoured $B$-Decays and $CP$-Asymmetries for Charmed Final Hadron States in Isgur and Wise Theory

open access: yes, 1993
The Cabibbo allowed non-leptonic $B$-decays in two hadrons are studied, within the factorization hypothesis, in the framework of Isgur and Wise theory for the matrix elements of the $\Delta B=-\Delta C=\pm 1$ weak currents.

Theta dependence of the vacuum energy density in chiral effective Lagrangian models at finite temperature, above $T_c$

open access: yes, 2019
In this work, extending a previous study at zero temperature ($T=0$), we perform a systematic study of the modifications to the QCD vacuum energy density $\epsilon_{vac}$ in the finite-temperature case, above the chiral transition at $T_c$, caused by a ...

The Proof of the Dijkgraaf-Vafa Conjecture and application to the mass gap and confinement problems

open access: yes, 2006
Using generalized Konishi anomaly equations, it is known that one can express, in a large class of supersymmetric gauge theories, all the chiral operators expectation values in terms of a finite number of a priori arbitrary constants.

Generalized Misner-Sharp Energy in f(R) Gravity [PDF]

open access: yes, 2009
We study generalized Misner-Sharp energy in $f(R)$ gravity in a spherically symmetric spacetime. We find that unlike the cases of Einstein gravity and Gauss-Bonnet gravity, the existence of the generalized Misner-Sharp energy depends on a constraint ...

Beyond a few bases: methods for large DNA insertion and gene targeting in plants. [PDF]

open access: yesPlant J
SUMMARY Genome editing technologies like CRISPR/Cas have greatly accelerated the pace of both fundamental research and translational applications in agriculture. However, many plant biologists are functionally limited to creating small, targeted DNA changes or large, random DNA insertions.

Silky bent grass (Apera spica-venti [L.] Beauv.) - a new host and reservoir of wheat dwarf virus

open access: yesPlant Protection Science, 1999
Wheat dwart virus (WDV) was detected by serological assays and transmission tests in samples of silky bent grass (Apera spica-venti [L.] Beauv.) that were taken in the field and showed signs of dwarfing, leaf yellowing and inflorescence reduction.

A búza törpülés vírus (Wheat dwarf virus) etiológiai vizsgálata és molekuláris jellemzése. = Etiology and molecular characterization of Wheat dwarf virus. [PDF]

open access: yes, 2011
A kutatások keretében az ország különböző helyeiről gyűjtöttünk vírusizolátumokat Átviteli kísérleteink során a WDV 11 nappal a kabócával történt inokuláció után már kimutatható volt a növényből, a víruskoncentráció 4-5 hétig emelkedett, majd csökkent.
