Lyonothamnus floribundus, or island ironwood, is a relictual endemic species found on only four of the eight California Channel Islands. It has been suggested that this species is capable of clonal growth, although the extent of clonality has not been determined. We have used random amplified polymorphic DNA (RAPD) analysis to examine clonality and genetic diversity in L. floribundus. We found that groves are largely genetically distinct clones, indicating that they are not remnants of a once… 
Extensive clonality of the endemic Calamagrostis pseudopurpurea Gerstl. ex O.R. Heine in central Germany revealed by RAPD markers.
TLDR
The results indicate that C. pseudopurpurea originates from two distinct periods of hybridisation between the same parental taxa, and that clonal propagation is most likely the main reproduction method.
Effects of clonality on the genetic variability of rare, insular species: the case of Ruta microcarpa from the Canary Islands
TLDR
It is found that clonality appears to positively affect the genetic diversity of R. microcarpa by increasing allelic diversity, polymorphism, and heterozygosity, and the results suggest that clonal propagation may benefit rare species.
Establishment and genetic structure of Empetrum hermaphroditum populations in northern Sweden
TLDR
It appears that E. hermaphroditum establishes by seeds to a larger extent than previously thought and that the clonal spread by layering is rather slow.
Patrones de distribución espacial en plantas clonales
TLDR
Using genotypic diversity indices, this paper did not find a consistent pattern between the spatial arrangement and outcorssing rates, but populations having both types of propagation and species that only have linked propagation have a higher spatially mixed genet and ramet distribution pattern than species thatonly have unlinked propagation.
Consequences of prolonged clonal growth on local and regional genetic structure and fruiting success of the forest perennial Maianthemum bifolium
TLDR
The results show that prolonged clonal growth and lack of sexual recruitment may affect within and between population genetic structure and the capability for sexual reproduction.
Conservation genetics of a Gondwana relict rainforest tree, Nothofagus moorei (F. Muell.) Krasser
TLDR
Populations of N. moorei appear to have retained significant levels of genetic diversity and show little population divergence in spite of marked reductions in the natural distribution since the Early Miocene, and individuals from four significantly differentiated groups identified using traditional F-statistics suggests individuals from each of these four groups should be included in future conservation plans.
Origins of Plant Diversity in the California Floristic Province
TLDR
Molecular phylogenetic studies spanning the flora indicate that immediate sources of CA-FP lineages bearing endemic species diversity have been mostly within North America—especially within the west and southwest—even for groups of north temperate affinity.
Genetic Differences between Wild and Artificial Populations of Metasequoia glyptostroboides: Implications for Species Recovery
TLDR
The results suggest that although the quantity and distribution range have been successfully restored, the genetic structure of M. glyptostroboides has not recovered appropriately, and additional ex situ genetic reserves should be established based on genetic knowledge and via appropriate approaches.
Adaptive radiation of shrubby tarweeds (Deinandra) in the California Islands parallels diversification of the Hawaiian silversword alliance (Compositae-Madiinae).
Phylogenetic analyses of nuclear rDNA transcribed spacers and cytogenetic studies of interspecific hybrids reported here uphold Carlquist's hypothesis (1965, Island Biology) that shrubby tarweeds

TLDR
It is postulated that large, long‐lived clones dominated genetic relationships within populations but also provided opportunities for gene flow between populations on a longer time scale.
Explaining the geographic distributions of sexual and asexual populations
TLDR
A mathematical model of a habitat that stretches from south to north in the Northern Hemisphere is constructed, and the idea that a single basic process may account for much of what is known about geographic parthenogenesis is supported.
Systematic and evolutionary implications of rbcL sequence variation in Rosaceae
TLDR
RbcL-based phylogenies suggest that chromosome numbers are more reliable indicators of some generic alliances than the more commonly used fruit types and that the subfamily Maloideae may have descended from spiraeoid ancestors and the pome is derived from follicular or capsular fruit types.
Self-incompatibility RNases from three plant families: homology or convergence?
TLDR
If the -RNases of the Rosaceae are homologous to those of the Scrophulariaceae and Solanaceae, then many other dicot families might be expected to share RNases as the mechanism of gametophytic self-incompatibility.
Molecular Markers, Natural History and Evolution
TLDR
A history of Molecular Phylogenetics and applications of individuality and Parentage, issues of Heterozygosity, and special Approaches to Phylageny Estimation are reviewed.
