The mountains of the southeast Iberian Peninsula harbor several narrowly endemic species belonging to Narcissus section Pseudonarcissi (N. alcaracensis, N. bugei, N. enemeritoi, N. longispathus, N. nevadensis, N. segurensis, and N. yepesii) that are protected by regional Spanish laws. Most of these trumpet daffodils show a very similar overall morphology, and the correct identification of species is difficult unless the geographical origins of the accessions are known. ISSR (Inter-Simple… 

Population Genetics Methods Applied to a Species Delimitation Problem: Endemic Trumpet Daffodils (Narcissus Section Pseudonarcissi) from the Southern Iberian Peninsula

Genetically, geographically, and ecologically well-defined lineages of the Pseudonarcissi section occur throughout the southern mountains of the Iberian Peninsula, generally supporting the traditional taxonomical delimitation of this lineage and qualifying as separate units of conservation.

Genetic diversity of Narcissus tortifolius, an endangered endemic species from Southeastern Spain

The results indicate that habitat fragmentation has not caused genetic depauperation in N. tortifolius but did reveal moderate genetic differentiation, and these findings could be used to establish management guidelines for the conservation of this rare species.

Genetic Diversity of some Daffodil (Narcissus L. spp.) Genotypes in Turkey by Using SRAP Markers

It can be concluded that genetic variation of Narcissus species can be used for daffodil breeding programs.

Population Genetics of Narcissus Species Reveals High Diversity and Multiple Introductions into Kashmir

The high diversity observed in the present investigation indicates that the Narcissus species have not gone through any bottleneck due to either multiple introductions or the presence of these species from decades.

Rasgos genéticos poblacionales aclaran el estatus taxonómico del narciso de Villafuerte y respaldan su conservación

Despite losing its taxonomic distinctiveness after being subsumed by the relatively abundant N. n.

New data on daffodils of the Narcissus nevadensis complex (Amaryllidaceae) in SE Spain: N. nevadensis subsp. herrerae subsp. nov., and N. nevadensis subsp. longispathus comb. nov.

The Iberian Peninsula is the centre of diversity for N. Pseudonarcissus, with N. nevadensis Pugsley being proposed as the ancestral species of this group (Fernandes 1951) and recently, after molecular analyses, this species has been separated into an independent section.

Molecular characterisation of the genus Papaver section Oxytona using ISSR markers

The inter-simple sequence repeat (ISSR) molecular marker system can be used for the classification of section Oxytona, which is found widely in the native flora of Turkey and is commercially important for high alkaloid content.

Multivariate morphometric analysis and taxa delimitation in two narrow Greek endemics: Astragalus maniaticus and Aethionema saxatile subsp. corinthiacum

Several multivariate morphometric analyses revealed that Astragalus maniaticus cannot be distinguished from A. suberosus subsp.

Genetic Diversity Analysis of Nine Narcissus Based on Morphological Characteristics and Random Amplified Polymorphic DNA Markers

. Genetic diversity of Narcissus was systematically studied on both morphological and molecular levels. Twenty-four characteristics of nine narcissi were observed and their differences evaluated by



Phylogenetic Relationships and Biogeography within the Eurasian Clade of Amaryllidaceae Based on Plastid ndhF and nrDNA ITS Sequences: Lineage Sorting in a Reticulate Area?

It is hypothesized that lineage sorting took place after the divergence of Galantheae and Narcisseae/Pancratium from a common genepool with Hannonia, Lapiedra, and Vagaria retaining a mosaic of the ancestral haplotypes, and North Africa and the Iberian Peninsula are the most likely areas of origin for the rest of the clade.

Isolated populations or isolated taxa? A case study in narrowly-distributed snapdragons (Antirrhinum sect. Sempervirentia) using RAPD markers

Although A. valentinum appeared the most closely related species to A. subbaeticum, molecular data suggested that this species merits taxonomic distinction, suggesting that isolation by distance is responsible for the distribution of genetic variation among Antirrhinum populations.

Mating patterns and genetic diversity in the wild Daffodil Narcissus longispathus (Amaryllidaceae)

Selfing rates and levels of genetic diversity at allozyme loci in six populations of Narcissus longispathus, a self-compatible daffodil endemic to a few mountain ranges in southeastern Spain, indicate that few selfed offspring survive to maturity because of inbreeding depression.

Phylogenetic reconstruction of the evolution of stylar polymorphisms in Narcissus (Amaryllidaceae).

Concentrated-changes tests indicate that a long, narrow floral tube may have been associated with the emergence of stigma-height dimorphism and that this type of tube, in combination with a deep corona, likely promoted, or at least was associated with, the parallel origins of heterostyly.

Assessing hybridization in natural populations of Penstemon (Scrophulariaceae) using hypervariable intersimple sequence repeat (ISSR) bands

The results do not support the hybrid origin of P. spectabilis, but do support the hypothesis that P. clevelandii is a diploid hybrid species derived from P. centranthifolius, and demonstrate that pollen‐mediated gene flow via hummingbird vectors is prevalent in the hybrid complex.

Assessment of genome origins and genetic diversity in the genus Eleusine with DNA markers.

Comparison of RFLP, RAPD, and ISSR technologies, in terms of the quantity and quality of data output, indicated that ISSRs are particularly promising for the analysis of plant genome diversity.

Collapse of species boundaries in the wild potatoSolanum brevicaule complex (Solanaceae, S. sect.Petota): Molecular data

The molecular results suggest that the Solanum brevicaule complex is paraphyletic as currently circumscribed, and many species of the S. brevicAUle complex should be relegated to synonymy.

Convergent evolution of flower polymorphism in Narcissus (Amaryllidaceae)

It is concluded that the two heterostylous species of NarcISSus have independent origins, supporting previous hypothesis of convergence of heterostyly in Narcissus and remarkable resemblance of flower features between both species indicates that pollinator activity might have driven flower convergence.

Genetic relationships among species of the genus Diplotaxis (Brassicaceae) using inter-simple sequence repeat markers

The genetic relationships among the ten Diplotaxis species estimated by the polymorphism of ISSR markers are in agreement with those previously inferred by other morphological, biochemical and molecular data, indicating the reliability of the ISSR approach for this purpose.

The history of the garden Narcissi

How far the study of chromosomes and a knowledge of hybridisation and documentary history can be used to reveal the origin and means of improvement of the garden daffodils is to be discovered.
