Three genes from Solanum chacoense coding for squalene synthase
… 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 coding for SQS. Three sqs gene homologs were isolated from S. chacoense, sqs1Sc, sqs2Sc, and sqs4Sc, that have 74 …

Bulk segregant analysis for anther culture response and leptine content in backcross families of diploid potato
… was high for leptine content in the foliage. Leptines were present in low levels in 43 of 87 genotypes in PBCp, indicating simple genetic control. In PBCc, only 7 of 42 genotypes expressed leptines, generally at a higher level than in PBCp, indicating cytoplasmic inheritance. Ten high and ten …

Molecular marker analysis of a segregating monoploid potato family
… only in the plants that do not synthesize leptines. Further investigation with larger populations is needed to confirm this possibility.

Protoplast Fusion for the Production of Intermonoploid Somatic Hybrids in Cultivated Potato
Monoploid potato genotypes represent plant material that is free from the "genetic load" of lethal and severely deleterious alleles normally present in the highly heterozygous cultivated potato species. Field evaluations enabled the identification of agronomically superior monoploid potato …
