 en Profiling carbohydrate composition, biohydrogen capacity, and disease resistance in potato
Roldán, Sergio Diez-de-Medina; Silva, Herman; Jeblick, Wolfgang; Nowik, Isabella; Modigell, Michael; Neuhaus, H. Ekkehard & Conrath, Uwe


Background: Potato ( Solanum tuberosum check for this species in other resources ) is one of the most important sources of carbohydrates in human diet. Because of its high carbohydrate levels it recently has also received attention in biohydrogen production. To exploit the natural variation of potato with respect to resistance to major diseases, carbohydrate levels and composition, and capacity for biohydrogen production we analyzed tubers of native, improved, and genetically modified potatoes, and two other tuberous species for their glucose, fructose, sucrose, and starch content.
Results: High-starch potato varieties were evaluated for their potential for Caldicellulosiruptor saccharolyticus check for this species in other resources -mediated biohydrogen production with Desirée and Rosita varieties delivering the highest biohydrogen amounts. Native line Vega1 and improved line Yagana were both immune to two isolates (A291, A287) of Phytophthora infestans check for this species in other resources .
Conclusions: Our data demonstrate that native potato varieties might have great potential for further improving the multifaceted use of potato in worldwide food and biohydrogen production.
