Characterization of a new densovirus infecting the green peach aphid Myzus persicae (2003)
Dullemans, A.M., Verbeek, M., Reinbold, C., Brault, V., ...
A new icosahedral DNA virus was isolated from aphids (Myzus persicae) that showed abnormal growth and development. The purified virus particles have a diameter of 20 nm and contain a single-stranded...
Dullemans, A.M., Verbeek, M., Reinbold, C., Brault, V., ...
The genomic sequence of a new icosahedral DNA virus infecting Myzus persicae has been determined. Analysis of 5499 nt of the viral genome revealed five open reading frames (ORFs) evenly distributed...
Gonsalves, M.C., Klerks, M.M., Verbeek, M., Vega, J.
Sugarcane yellow leaf virus (ScYLV) is widely distributed in Brazil and other sugarcane producing countries causing significant yield losses. Due to the high incidence of the aphid vector, the virus...
The complete nucleotide sequence of an ophiovirus associated with lettuce big-vein disease has been elucidated. The genome consisted of four RNA molecules of approximately 7ò8, 1ò7, 1ò5 and 1ò4...

Survival, look-ahead bias and the persistence in hedge fund performance (2002)
Baquero, G., Horst, J. Ter, Verbeek, M.
Hedge funds databases are typicall subject to high attrition rates because of fund termination and self-selection. Even when all funds are included up to their last available return, one cannot...
Mechanical transmission of poleroviruses (2001)
Hoffmann, K., Verbeek, M., Romano, A., Dullemans, A.M.
Previously, transmission of poleroviruses has relied solely on the use of their aphid vectors. Biolistic inoculation allowed for the first time the mechanical transmission of Beet western yellows...

A novel isothermal multiplex AmpliDet RNA system is described for the simultaneous amplification and detection of Potato leafroll virus (PLRV) and Potato virus Y (PVY) in seed potatoes. The risk of...
Factors affecting the species composition of arable field boundary vegetation (2000)
1. In recent decades the botanical diversity of arable field boundaries has declined drastically. To determine the most important factors related to the species composition of arable field...
Hogenhout, S.A., Verbeek, M., Goldbach, R.W.
Luteoviruses avoid degradation in the hemolymph of their aphid vector by interacting with a GroEL homolog from the aphid's primary endosymbiotic bacterium (Buchnera sp.). Mutational analysis of GroEL...

Estimation of Time Dependent Parameters in Linear Models Using Cross Sections, Panels or Both (1988)
Estimating dynamic models from repeated cross-sections
An important feature of panel data is that it allows the estimation of parameters characterizing dynamics from individual level data. Several authors argue that such parameters can also be identified...
