The Codling Moth (Cydia pomonella L.), is one of the most notorious pest species threatening apple, pear, walnuts and other fruit orchards worldwide. Olfaction plays a dominate role in the ‘host’-selection behavior of the Codling Moth. Earlier, based on antennal transcriptome analysis we identified a number of critical elements of the moth olfactor...

Tortricid moths (Lepidoptera: Tortricidae) include some of the world’s most devastating insect species for agricultural products. Among tortricids, we focused our research on two model species which are also two of the main organisms threatening agricultural economy in Trento Province: the codling moth Cydia pomonella, and the grapevine moth Lobesi...

The application of New Breeding Techniques (NBTs) in Vitis vinifera is highly desirable to introduce valuable traits while preserving the genotype of the elite cultivars. However, a broad application of NBTs through standard DNA-based transformation is poorly accepted by public opinion and law regulations in Europe and other countries due to the st...

The production and cultivation of vines ( Vitis vinifera ) tolerant or resistant to diseases such as downy mildew (DM) is a promising strategy to reduce fungicides and help viticulture sustainability. In many crops, generation of knock-out mutants in host genes controlling susceptibility to DM, such as Downy Mildew Resistant 6 ( DMR6 ) is a strateg...

Agrobacterium tumefaciens- mediated gene transfer—actually the most used method to engineer plants—may lead to integration of multiple copies of T-DNA in the plant genome, as well as to chimeric tissues composed of modified cells and wild type cells. A molecular characterization of the transformed lines is thus a good practice to select the best on...

Fire blight disease, caused by the bacterium Erwinia amylovora ( E. amylovora ), is responsible for substantial losses in cultivated apples worldwide. An important mechanism of plant immunity is based on the recognition of conserved microbial molecules, named pathogen-associated or microbe-associated molecular patterns (PAMPs or MAMPs), through pat...

CRISPR-Cas technology has widely extended the application fields of genome editing in plant breeding, making possible specific and minimal mutations within a genetic pool. With respect to standard genome editing technologies, CRISPR-Cas machinery can be introduced in the form of ribonucleoproteins (RNPs), thus avoiding the introduction of exogenous...

Full-text available
Genome editing via CRISPR/Cas9 is a powerful technology, which has been widely applied to improve traits in cereals, vegetables and even fruit trees. For the delivery of CRISPR/Cas9 components into dicotyledonous plants, Agrobacterium tumefaciens mediated gene transfer is still the prevalent method, although editing is often accompanied by the inte...
Article
The European grapevine moth, Lobesia botrana, is one of the most important pests of grape. Feeding activity by caterpillars leads to direct damage to reproductive plant tissues (flower buds and berries), and also to indirect damage by promoting secondary infections by microorganisms. Current control systems are based either on the use of insecticid...

Article
Full-text available
In vascular plants the cell-to-cell interactions coordinating morphogenetic and physiological processes are mediated, among others, by the action of hormones, among which also short mobile peptides were recognized to have roles as signals. Such peptide hormones (PHs) are involved in defense responses, shoot and root growth, meristem homeostasis, or...
Article
Full-text available
Herbivorous insects use olfactory cues to locate their host plant within a complex olfactory landscape. One such example is the European grapevine moth Lobesia botrana, a key pest of the grape in the Palearctic region, which recently expanded both its geographical and host plant range. Previous studies have showed that a synthetic blend of the thre...

Full-text available
Peach is a climacteric species whose ripening is regulated by the plant hormone ethylene. A crosstalk mechanism with auxin is necessary to support climacteric ethylene synthesis. The homeostasis control of auxin is regulated also by the activity of peptide hormones (PHs), acting both as short and long distant ligands. In this work, we investigated...

Olfaction plays a dominant role in the mate-finding and host selection behaviours of the codling moth (Cydia pomonella), an important pest of apple, pear and walnut orchards worldwide. Antennal transcriptome analysis revealed a number of abundantly expressed genes related to the moth olfactory system, including those encoding the olfactory receptor...
Article
Full-text available
Transient receptor potential (TRP) channels are an ancient family of cation channels, working as metabotropic triggers, which respond to physical and chemical environmental cues. Perception of chemical signals mediate reproductive behaviors and is therefore an important target for sustainable management tactics against the codling moth Cydia pomone...
Article
Ε−(β)-caryophyllene is a sesquiterpene volatile emitted by plants and involved in many ecological interactions within and among trophic levels and it has a kairomonal activity for many insect species. In grapevine it is a key compound for host-plant recognition by the European grapevine moth, Lobesia botrana, together with other two sesquiterpenes....

Olfaction plays a major role in host selection behavior in the Codling Moth (Cydia pomonella L.), one of the most notorious pest species threatening apple orchards worldwide. Functional expression of C. pomonella olfactory receptors (CpomORs) not only allows investigating mechanisms of insect OR functioning but also developing novel means to interv...
