Natural variation in five candidate genes of the steroidal glycoalkaloid (SGA) metabolic pathway and whole-genome single nucleotide polymorphism (SNP) genotyping were studied in six wild [Solanum chacoense (chc 80-1), S. commersonii, S. demissum, S. sparsipilum, S. spegazzinii, S. stoloniferum] and cultivated S. tuberosum Group Phureja (phu DH) potato species with contrasting levels of SGAs. Am...

Dry mal1er content in potato (Sownum ruberosum L.) ls an Im­ portant factor in processing llIId is ~imatl,d by specific gravlty. We perfonned quantitative tfBit loci (QTL) analysis for this trait in lx potato in three environments, A population of 110 IndJviduals WItS derived from the croSiS of It hybrid ot haploid S. ruberosum (lx) lUld S. ch4coense Bitter, with II S. phureja Juz. & Bull. clon...

Within a population of F hybrids between two genotypes ( L. Group Phureja DM 1-3 516 R44 [DM] and L. Group Tuberosum RH89-039-16 [RH]) used in the potato genome sequencing project, we observed fruit set after self-pollination on many plants. Examination of pollen tube growth in self-fertile and self-unfruitful F plants after controlled self-pollinations revealed no difference in the ability of ...

It has long been known that the phytohormone auxin plays a promoting role in tuber formation and stress tolerance potatoes. Our study aimed to identify characterize complete sets of auxin-related genes presumably constitute entire signaling system potato (Solanum tuberosum L.). The corresponding were retrieved from sequenced genomes doubled monoploid S. DM1-3-516-R44 (DM) Phureja group, heteroz...

Late blight, caused by Phytophthora infestans (Mont.) de Bary, is the most destructive disease of potato worldwide. As this pathogen can rapidly overcome major race-specific resistance genes, identifying the basis for enhanced quantitative resistance has become a crucial element for implementing advanced breeding strategies. A population of 230 full-sib progeny derived from a cross between two ...
