Hypersensitive response to Aphis gossypii Glover in melon genotypes carrying the Vat gene.
Aphis gossypii Glover causes direct and indirect damage to Cucumis melo L. crops. To decrease the harmful effects of this pest, one of the most economically and environmentally acceptable options is to use genetically resistant melon varieties. To date, several sources of resistance carrying the Vat gene are used in melon breeding programmes that aim to prevent A. gossypii colonization and the ...
متن کاملHoneydew and Specialty Melon Evaluation
Five cultivars of honeydew and speciality type melons were evaluated in 2001. Performance from all cultivars was less than optimum. Foliage diseases and fruit cracking and rotting resulted in an extremely large percentage of the fruits having to be graded as culls. This also resulted in smaller fruits than desired. ‘Passport’, an early maturing, speciality type melon has characteristics that me...
متن کاملValidity of Using Recombinant Melon Profilin, Cuc m 2, for Diagnosis of Melon Allergy
Background: Allergy is a clinical disorder affecting humans worldwide. Allergenic extracts prepared from natural source materials remain heterogeneous in composition and content, but are regularly used for diagnosis and immunotherapy. Recombinant allergens are suitable candidates to use in place of natural allergens; however, the recombinant allergens should be assessed and compared with the na...
متن کاملResponse of the melon aphid, Aphis gossypii, to host- plant resistance: evidence for high adaptive potential despite low genetic variability
In agrosystems, pests are submitted to strong human-imposed selective pressures to which they sometimes adapt rapidly, either through selection of genotypes resulting from mutation and ⁄or recombination events, or through phenotypic plasticity. Understanding how insects respond to such selective pressures is of great importance for sustainable pest management strategies, such as the use of resi...
متن کاملExpression of Small RNA in Aphis gossypii and Its Potential Role in the Resistance Interaction with Melon
BACKGROUND The regulatory role of small RNAs (sRNAs) in various biological processes is an active area of investigation; however, there has been limited information available on the role of sRNAs in plant-insect interactions. This study was designed to identify sRNAs in cotton-melon aphid (Aphis gossypii) during the Vat-mediated resistance interaction with melon (Cucumis melo). METHODOLOGY/PR...
