North American potato production differs from other geographical regions such as Europe in that it is essentially a closed system, i.e., seed potatoes are not imported and production is dominated by only a few cultivars. The lack of significant seed

Potato tubers (Solanum tuberosum L. cv. Monalisa) showing superficial necrotic rings typical of Potato virus Y NTN (PVYNTN) infection were collected from commercial potato fields in the State of Sao Paulo (Brazil). An isolate named IAC-PVYNTN was cha

In the course of a multi-year survey of Potato virus Y (PVY) incidence and diversity in the U.S. seed potato crop, an unusual PVY variant was identified in low but significant levels in multiple states. This variant, PVYO-O5, was initially detected b

Growth chamber and greenhouse experiments were conducted to investigate the effect of temperature and irradiance on foliar glycoalkaloids of three potato genotypes (Solanum tuberosum L.) that differ in glycoalkaloid content. Two genotypes (ND4382-17

A potato, Solanum spp. hybrid, clone was identified that responded to egg masses of the Colorado potato beetle, Leptinotarsa decemlineata (Say), with a hypersensitive necrotic zone that subsequently disintegrated around the border and detached from t

Potato (Solanum tuberosum L.) responds to heat stress with a shift in partitioning from tubers to shoots. Enzymes responsible for sucrolysis previously have been used as indicators of sink strength and are likely involved in controlling flow of carbo

This study was undertaken to determine the role of sucrose-metabolizing enzymes in altered carbohydrate partitioning caused by heat stress. Potato (Solanum tuberosum L.) genotypes characterized as susceptible and tolerant to heat stress were grown at

Potato plants are sensitive to heat stress, which reduces tuber yield and alters whole plant partitioning. This study was conducted to determine the effect of high temperature on activity of enzymes related to sucrose metabolism in source and sink ti
