Biosynthesis of Steroidal Glycoakaloids in Solanum chacoense Bitter
… between SGAs and gene expression levels. Solanum chacoense, a wild potato species was used as a model plant from which tissues were harvested at specified developmental stages and analyzed for SGA content. The results from the SGA analysis suggest a qualitative and quantitative tissue- and …

Three genes from Solanum chacoense coding for squalene synthase
… deter feeding by potato pests. The wild potato Solanum chacoense accumulates higher amounts of SGAs than cultivated potato and some of its accessions produce leptines, a rare class of SGAs that is toxic to Colorado potato beetle. Unlike most eukaryotes, higher plants have more than one gene …

Derivation of interspecific Solanum hybrid genotypes with resistance to Colorado potato beetle (Leptinotarsa decemlineata Say)
The anther culture response of diploid Solanum chacoense (chc) - S. phureja (phu) hybrids and the regeneration potential of anther-derived monoploids was evaluated. In vivo evaluation of interspecific hybrids was also performed. Three hybrids were anther cultured to observe the effects of reduced …

Genetic studies of candidate genes in the glycoalkaloid biosynthetic pathway of potato
Potato (Solanum tuberosum L) is an outcrossing, highly heterozygous cultivated in which the elucidation of the genetic basis of quantitative traits, is more complex than in self-pollinated crops. Both a candidate gene approach and a whole genome SNP genotyping analysis were used to assess allelic …

Embryogenic response of potato anther culture to colchicine
… conducted. Anther culture of a hybrid between <i>Solanum chacoense</i> and <i>S. phureja</i> (clone CP2) was conducted with five colchicine treatments (0, 25, 50, 100, and 200 mg/L) for 24 h. Anthers containing late uninucleate pollen were cultured on modified liquid LS medium. A mean of 0.25 …

Molecular marker analysis of a segregating monoploid potato family
… between high leptine producing selections of Solanum chacoense Bitt. and anther culture responsive selections of Solanum phureja Juz. et Buk. Several steps of the anther culture process were studied. The results indicated that genotype remains the main factor affecting anther culture response. …
