Antagonistic interactions between the biocontrol agents Beauveria bassiana and Heterorhabditis indica

Darissa, Omar (Russian Journal of Nematology, 2014)

The effect of the pathogenic fungus, Beauveria bassiana, on the invasion and proliferation of the entomopathogenic nematode, Heterorhabditis indica, in larvae of the waxmoth, Galleria mellonella, was investigated. ...

Application of FTACards to Sample Microbial Plant Pathogens for PCR and RT-PCR

Grund, Elisabeth; Darissa, Omar; Adam, Guenter (Journal of Phytopathology, 2010-11-02)

For the detection of microbial plant pathogens, like fungi, bacteria, viruses and viroids, methods based on nucleic acids have gained importance as the availability of sequence information increased. This requires ...

The Development of Agricultural Biotechnology Capacities in Palestine through the UNESCO Biotechnology Educational and Training Center at Bethlehem University

Darissa, Omar; Iraki, Naim (Springer, 2007-01)

A dsRNA mycovirus causes hypovirulence-associated traits in Fusarium graminearum

Darissa, Omar (European Journal of Plant Pathology, 2012-04-03)

The association of Fusarium graminearum isolate China-9 with the dsRNA mycovirus FgV-ch9 was evaluated for hypovirulence-related traits. Single conidia-originating cultures of China-9 isolate can be associated either with ...

Effect of Beauveria bassiana on the invasion and proliferation of the entomopathogenic nematode Heterorhabditis indica inside Galleria mellonella larvae

Darissa, Omar; Iraki, Naim (IOBC, 2003-01)

Endemic seeds: Importance and Improvement Approaches

Genotyping of sixteen grapevine (Vitis vinifera) varieties in Palestine using microsatellite markers

Darissa, Omar (Bethlehem University Journal, 2013)

Cultivated grapevines (Vitis vinifera L. ssp. Sativa) are economically the second important fruit-trees after olives in Palestine with more than 20 cultivars covering about 7% of the total cultivated lands and an annual ...

In vivo and In vitro interactions between two entomopathogens: the bacterium Serratia marcescens and the nematode Heterorhabditis indica

Darissa, Omar (Russian Journal of Nematology, 2013)

The influence of interaction between Serratia marcescens and Heterorhabditis indica on the penetration, development and proliferation of the latter inside Galleria mellonella larvae was investigated. The preinfection ...

Making a friend from a foe: expressing a GroEL gene from the whitefly Bemisia tabaci in the phloem of tomato plants confers resistance to tomato yellow leaf curl virus

Darissa, Omar; Akad, Fouad; Iraki, Naim (Archives of Virology, 2007-03-05)

Some (perhaps all) plant viruses transmitted in a circulative manner by their insect vectors avoid destruction in the haemolymph by interacting with GroEL homologues, ensuring transmission. We have previously shown that ...

Using the Anchored Microsatellite Primed Polymerase Chain Reaction (AMP-PCR) Technique to Study Genetic Diversity in Four Local Tomato (Lycopersicum esculentum) Cultivars in Palestine
