This data article provides the weights, specific gravities and chemical compositions (moisture, protein, fat, ash, and carbohydrate) of potato tubers, for food processing use, from the Tokachi, Kamikawa and Abashiri areas of Hokkaido, Japan. Potato tubers of four cultivars ('Toyoshiro', 'Kitahime', 'Snowden' and 'Poroshiri') were employed in the current study. The weights and specific gravities...

Two transgenic potato lines csr2-1 and csr4-8, containing two different antisense constructs, csr2 and csr4, respectively, were crossed to investigate the possibility of achieving double transformants with combined effects of the two antisense transgenes on plant phenotypes and cellulose deposition. Molecular analysis revealed an expected segregation ratio of 1:1:1:1 of the four classes. Phenot...

storage of potatoes is very important because fresh potatoes are available only for a few months in a year. thus, any treatment such as irradiation that controls sprout growth and extends shelf life of potatoes could be beneficial. in this study, potato sprout inhibition and tuber quality after treatment with various levels of gamma irradiation (0, 50, 100 and 150 gy) on different dates (10, 30...

to investigate the appropriate distribution of nitrogen fertilizer application and optimum amount of phosphorus fertilizer to achieve high quality and quantitative yield in edible and seed potato (solanum tuberosum l.) tubers, this experiment was conducted in research farm of the college of agriculture and natural resources, university of tehran in 2012. the experiment was performed a strip spl...

Calystegines are hydroxylated nortropane alkaloids derived from the tropane alkaloid biosynthetic pathway. They are strong glycosidase inhibitors and occur in vegetables such as potatoes, tomatoes, and cabbage. Calystegine accumulation in root cultures was described to increase with carbohydrate availability. Whether this is indicative for the in planta situation is as yet unknown. Potatoes are...

The potential effect of genetic modification on nutritional properties of potatoes transformed to improve resistance to a necrotic strain of Potato virus Y was determined in a rat experiment. Autoclaved tubers from four transgenic lines were included to a diet in the amount of 40% and compared with the conventional cv. Irga. The experiment lasted 3 weeks and special attention was paid to nutrit...

Polyphenol oxidase (PPO) activity in potato (Solanum tuberosum) plants was high in stolons, tubers, roots, and flowers but low in leaves and stems. PPO activity per tuber continued to increase throughout tuber development but was highest on a fresh weight basis in developing tubers. PPO activity was greatest at the tuber exterior, including the skin and cortex tissue 1 to 2 mm beneath the skin....

Commentary In any form of epilepsy associated with distinct anatomical le-sions within the brain, questions arise as to whether the lesional tissue alone is epileptogenic, whether perilesional cortex is also epileptogenic, or whether even more remote cortical regions that appear structurally normal may serve as independent epileptic foci. In disorders associated with multiple distinct lesions, ...
