PREMISE OF THE STUDY The species boundaries of wild and cultivated potatoes are controversial, with most of the taxonomic problems in the cultivated potato clade. We here provide the first in-depth phylogenetic study of the cultivated potato clade to explore possible causes of these problems. METHODS We examined 131 diploid accessions, using 12 nuclear orthologs, producing an aligned data set of 14,072 DNA characters, 2171 of which are parsimony-informative. We analyzed the data to produce… Expand
Analyses of 202 plastid genomes elucidate the phylogeny of Solanum section Petota
TLDR
The present plastid analysis discovered the same major clades as the nuclear data but with some substantial differences in topology within the clades. Expand
Recent Large-Scale Genotyping and Phenotyping of Plant Genetic Resources of Vegetatively Propagated Crops
TLDR
This review describes some of the approaches taken in genotyping and/or phenotyping projects concerning a wide variety of vegetatively propagated crops and suggests co-operative projects with broad-scale data collection are likely to produce more reliable results. Expand
Potato Germplasm Enhancement Enters the Genomics Era
TLDR
This paper discusses potato germplasm enhancement efforts in the past, focusing on effective examples such as disease resistance and processing quality, and outlines new strategies for enhancement efforts, shifting the focus from evaluating phenotypes to tracking and manipulating specific DNA sequences.

The Central Role of Taxonomy in the Study of Neotropical Biodiversity1
Abstract The Neotropics are the most species-rich area of the planet. Understanding the origin and maintenance of this diversity is an important goal of ecology and evolutionary biology. Success inExpand
Polymorphism and Phylogeny of the Vacuolar Invertase Inhibitor Gene INH2 Homologs in Solanaceae Species
TLDR
A significant level of interspecific polymorphism of the INH2 coding sequence was found within the Petota and Lycopersicon sections, which corresponds to the high mutation rate during the evolution of the InH2 genes and presumably associated with the modern plant diversity. Expand

Collapse of morphological species in the wild potato Solanum brevicaule complex (Solanaceae: sect. Petota).
TLDR
Phenetic analyses of morphological phenetic species boundaries of these putative progenitors and five cultivated taxa suggest that Hawkes's 1990 treatment of 232 morphological species is an overestimate for sect. Expand
Do potatoes and tomatoes have a single evolutionary history, and what proportion of the genome supports this history?
TLDR
This study confirms and quantifies the utility of using DNA sequences from different parts of the genome in phylogenetic studies to avoid possible bias in the sampling and reveals and summarized the extensive discordance among COSII markers. Expand
AFLP analysis reveals a lack of phylogenetic structure within Solanum section Petota
TLDR
Most of the series that Hawkes and his predecessors designated can not be accepted as natural groups and neither do they find proof for the 4 clades proposed by Spooner and co-workers, based on this study. Expand
Single copy nuclear gene analysis of polyploidy in wild potatoes (Solanum section Petota)
TLDR
The results document considerable genomic complexity of some wild potato polyploids that can be explained by multiple hybrid origins and allele losses that provide a clear biological explanation for the taxonomic complexity in wild potatoPolyploid evolution. Expand
Systematics, Diversity, Genetics, and Evolution of Wild and Cultivated Potatoes
TLDR
A historical overview and update since 1990 of the systematics, diversity, genetics, domestication, evolution, and breeding of Solanum section Petota is provided that will serve as a reference for the next generation of studies in the potato. Expand
Analyses of 202 plastid genomes elucidate the phylogeny of Solanum section Petota
TLDR
The present plastid analysis discovered the same major clades as the nuclear data but with some substantial differences in topology within the clades. Expand
A single domestication for potato based on multilocus amplified fragment length polymorphism genotyping.
TLDR
Preliminary phylogenetic analyses support a monophyletic origin of the landrace cultivars from the northern component of this complex in Peru, rather than from multiple independent origins from various northern and southern members. Expand
Phylogenetic Relationships of Solanum Series Conicibaccata and Related Species in Solanum Section Petota Inferred from Five Conserved Ortholog Sequences
TLDR
Low bootstrap support values and morphological similarity suggest recent origins and the need for a reduction in number of recognized species in series Conicibaccata. Expand
Phylogeny of Solanum series Piurana and related species in Solanum section Petota based on five conserved ortholog sequences.
TLDR
A set of five conserved orthologous DNA markers (cos II) with 5342 bp of aligned length were used to infer the phylogeny of putative members of Solanum ser. Expand
Taxonomy of North and Central American diploid wild potato (Solanum sect. Petota) species: AFLP data
TLDR
The Wagner parsimony and phenetic analyses mostly agreed with the morphological data in supporting currently recognized species except that they suggest that S. brachistotrichium and S. stenophyllidium are conspecific. Expand
