“…Resistance to insect predation is lID important purpose of the process. The most successful strategy is B. thuringiellsis 8-endotoxin-expressing transgenic plants such as transgenic tobacco toxic to tobacco hornworm, Malldllca sexta (L.), larvae and transgenic tomatoes resistant to corn earworm, Heliothis zea (Boddie) (Fischhoff et al 1987, andHouck et al 1993). The relationship between the amount of CryIA(b) (B. t. kllrstaki) protein expressed in the plant and the level of protection from the pest damage was positive (Warren et al 1992).…”

We exposed larval and adult Hippodamia convergens (Guerin-Meneville),convergent lady beetle, to Myzus persicae (Sulzer), green peach aphid, reared on potatoes expressing &-endotoxinof Bacillus thuringiensis tenebrionis. Because the toxin may be ingested by the aphid, the beetle may in tum be exposed to the toxin. However, we measured no statisticallysignificanteffect on survival,aphid consumption, development, or reproduction in beetles.

“…A recent literature survey revealed over 200 research reports on Agrobacteriummediated transformation of potato (Koivu et al, 1995). Most of these studies were directed to the development of pathogen-derived resistance to diseases (e.g., virus coat protein-mediated resistance to viruses) and also genetically engineered resistance to insects in cultivars with otherwise good agronomic characters (Houck et al, 1993;Beck and Ulrich, 1993). There is little doubt that such approaches will be increasingly employed for cultivar improvement.…”

“…Tissue culture techniques and genetic transformation are well developed and widely employed in potato research (reviewed in Houck et al, 1993;Bradshaw and MacKay, 1994). A recent literature survey revealed over 200 research reports on Agrobacteriummediated transformation of potato (Koivu et al, 1995).…”

Steroidal glycoalkaloids (SGAs) are produced following the general steroid biosynthesis pathway, starting from acetyl-coenzyme A and followed by the intermediates mevalonic acid, squalene, cycloartenol, and cholesterol. a-Chaconine and a-solanine are the main SGAs of the cultivated potato (Solanurn tuberosum), whereas many other SGAs are known in the wild potato species. Low concentrations of SGAs improve the taste of potato, but concentrations greater than 200 mgkg can have toxic effects on animals and humans. SGAs have antimicrobial activity and confer resistance to some insects, but many such pests of potato are not greatly affected. Certain environmental conditions and wounding enhance SGA accumulation in tubers in the field and storage. Low production of SGAs is a dominant character inherited in a relatively simple manner and can be selected for in potato-breeding programs, whereas the use of wild potato germplasm tends to increase the SGA accumulation in the breeding lines. Further efforts are likely to be directed toward the reduction of the SGA content in the edible potato products through breeding and biotechnological methodologies, whereas potato genotypes with high SGA production may be developed for use in the pharmaceutical industry.
