Safety Assessment of Potatoes Resistant to Colorado Potato Beetle

Safety assessment of genetically engineered potatoes with designed soybean glycinin: compositional analyses of the potato tubers and digestibility of the newly expressed protein in transgenic potatoes

“…The compositional analyses employed here were more extensive than those hitherto performed on commercial potatoes bred with classical methods. 3 The analyses were carried out with regard to about 50 components, which are nutritionally and toxically important classes of compounds in potato tubers. Because the compositional values of MQ were almost the same as those previously published, the composi- tional analyses made on transgenic potatoes with soybean glycinin genes are considered to be reliable.…”

“…3 However, in the storage proteins of the potato tuber, the levels of leucine, lysine, and threonine are low and insuf®cient for the nutrition of children under 5 years. 4 In order to improve the nutritional defects and to add novel physiological functions arising from glycinin, we have constructed transgenic potatoes with intact and modi®ed genes for soybean glycinin.…”

Evaluation of glycoalkaloids in tubers of genetically modified virus Y-resistant potato plants (var. Désirée) by non-aqueous capillary electrophoresis coupled with electrospray ionization mass spectrometry (NACE–ESI–MS)

“…Potatoes (Solanum tuberosum) have been considered for a long time to be the most important crops for human consumption [1,2]. The control of pathogens infecting potato is a key factor in increasing the quality, yield, and profitability of such a product.…”

Testing for Genetic Manipulation in Plants

“…However, the lysine content is low in ordi-nary rice and insufficient for children, particularly those under 2 years (FAO/WHO/UNU 1985). The potato tuber is currently considered to be an important food for the ingestion of selected vitamins and minerals such as vitamin B6, ascorbic acid and potassium (Lavirk et al 1995). However, the levels of leucine, lysine and threonine in the storage proteins of potato tubers are low and insufficient for the nutritional needs of children under 5 years (FAO/WHO/UNU 1985).…”
