Resistance of Wild Solanum Accessions to Aphids and Other Potato Pests in Quebec Field Conditions
Two experiments were done to determine the susceptibility of six wild potato accessions to the aphids Macrosiphum euphorbiae (Thomas) (Hemiptera: Aphididae) and Myzus persicae (Sulzer). Densities of aphid colonies were compared between caged Solanum pinnatisectum Dunal (Solanales: Solanaceae), S. polyadenium Greenmam, S. tarijense Hawkes, S. infundibuliforme Philippi, S. oplocense Hawkes, and S...
متن کاملMapping and Characterization of the Interaction Interface between Two Polypyrimidine-Tract Binding Proteins and a Nova-Type Protein of Solanum tuberosum
Polypyrimidine tract-binding (PTB) proteins are RNA-binding proteins that generally contain four RNA recognition motifs (RRMs). In potato, six cDNAs encoding full-length PTB proteins have been identified. In the present study Nova1-like protein, designated StNova1, was identified as a potential interacting partner of the StPTB proteins via yeast two-hybrid screening. Nova protein is a RNA-bindi...
متن کاملEvaluation of antioxidant activity of three common potato (Solanum tuberosum) cultivars in Iran
Objectives: Potato (Solanum tuberosum L.), as a whole food, contains high levels of vitamins and important antioxidants including phenolic acids, carotenoids and flavonoids. The objective of this study was to determine the total phenolic content and antioxidant activities of three common potatoes (Solanum tuberosum) cultivars in Iran i.e., Savalan, Agria and Sante. Materials and Methods: Pheno...
متن کاملReproduction of Globodera rostochiensis on Transformed Roots of Solanum tuberosum cv. Desiree.
Transformed roots of the susceptible potato Solanum tuberosum L. cv. Desiree were inoculated with second-stage juveniles (J2) of Globodera rostochiensis pathotype Rol. Adult males emerged after 3-4 weeks and matings with females occurred. After 8 weeks gentle pressure on the eggs of maturing females released the J2 which were viable. Because this technique enables the production of vigorously g...
متن کاملDifferential Protein Expression in Response to Abiotic Stress in Two Potato Species: Solanum commersonii Dun and Solanum tuberosum L.
Better knowledge on responses to dehydration stress could help to improve the existing cryopreservation protocols for potato, since plant tissues processed for cryopreservation are often submitted to similar in vitro stress conditions. Cryopreservation (the best method of conservation for vegetatively propagated plants) of potato still needs to be standardized to make it available and to conser...
