    Utilizing the Root Knot Nematodes effectors tool box for developing plant resistance to nematodes
    Root-Knot-Nematode (RKN) are highly specialized, obligatory plant parasites and are considered extremely destructive pathogens with a cosmopolitan distribution and a host range that spans most crops. The core interaction with their host is based on the establishment and maintenance of physiologically fully functional feeding site which are necessary for the survival of these nematodes. Feeding site construction is the result of extensive secretion of effectors from two different glands which are active during parasitism. Recently, a detailed lipidomics analysis during tomato root infection by RKN indicated on clear induction of many plant oxygenated fatty acids, oxylipins. In an effort to analyze nematode effectors which might be affected by plant oxylipins signals, we conducted RNAseq of second stage juveniles (J2s) exposed to the 9-HOT (9-Hydroxyoctadecatrienoic acid) known as a potent inducer of root waving. Among the differentially expressed genes, 177 genes with a N- terminal se

    Revealing proteins invovled in the transmission of viruses and bacteria by insect vectors
    Many plant pathogens such as viruses and bacteria are transmitted by insect vectors. In our ptojects we use an arsenal of methods to identify and verify proteins in insect vectors that have a role in the transmission of these pathogens. Such proteins could be targeted to interefere with and prevent the transmission.

    Host-pathogen interaction: Entomopathogenic microorganism and arthropod host
    Our research focus on arthropod pathogen from various perspectives and is primarily directed towards understanding the basic interaction between the pathogen and its invertebrate host. Ongoing projects are broad ranging from the most intimate interaction and disease initiation and progression to population studies, epizootiology and persistence of the pathogen in the environment.

    Interactions between honey bee and its major parasite Varroa destructor: focus on chemosensing
    The European honeybee, Apis mellifera, is considered to be the main pollinator of the agricultural crops globally. Although honeybees are exposed to a variety of risk factors, infestation by the ectoparasitic mite (Varroa destructor) is considered as the most significant health problem of A. mellifera worldwide. The research efforts aim towards development of an integrated strategy for Varroa pest management targeting hemosensory mechanisms of both honeybees and Varroa. In particularly we focus on molecullar mechanism behind Varroa and bee chemosensing

    Bio-sensors for rapid identification of fungal pathogens in tomato and grapvine
    Causative agents of mildew and mold are a major problem in agricultural crops. Available sensor technology for pathogen detection is based on hyper-spectral analysis of the changes in wavelengths emitted from sick plants due to chlorophyll breakdown, where the disease is advanced and no longer effectively treatable. In this proposal, we will develop a biosensor capable of identifying mildew and mold causative agents in tomato and vine at very early stages of pathogenesis, where the use of fungicides and control agents is still effective in reducing crop losses. In the future, our technology can be applied to any transformable crop.

    Generating fungal resistance in tomato through trichome genetics and synthetic modelling
    Mildews and molds are the cause of significant tomato crop losses worldwide. By harnessing the power of tomato genetics and biomimetic modelling, this proposal aims to generate tomato varieties resistant to molds and mildews. Using the causative agents B.cinerea (a necrotrophic/ hemibiotrophic pathogen) and O.neolycopersici (an obligatory biotrophic pathogen), we will screen an introgression population of the wild tomato S.habrochaites that we have found to be resistant to gray mold, to determine the chemical and structural trichome properties associated with mold and mildew resistance, subsequently introducing these properties into commercial tomato varieties.

    Architectural effects in plant-microbe interactions (PMI)
    Why are there so many different leaf shapes in nature? The leaf, an organ intended to serve similar functions in terrestrial plants, has acquired divergent structures through millennia of evolution. To date, excluding adaptation to extreme environments, few evolutionary advantages for particular leaf structures over others have emerged. We hypothesize that certain leaf structures were retained due to advantages in resistance to plant pathogens and in beneficial Plant Microbe Interactions (PMI). The ultimate goal of this project is to uncover the effect of plant structure on plant immunity and PMI.

    Editing vegetable for virus resistance
    Editing by CRISPR/Cas9 has been shown to be an efficient technology for precise DNA changes in various organisms. We have shown the ability to generated non-transgenic plants which are resistant to several viruses by knockout of the eIF4E gene. Based on this work we intend to develop virus resistance in important crops by knockout or amino acid replacement of susceptibility (recessive) and resistance genes. In addition, in this study we intend to improve plant editing with various alternative technologies in addition to Agrobactrium transformation. The study will combine molecular technology with plant transformation, and include plant-virus interaction.
