Open AccessRiparian populations of minnesota reed canarygrass (Phalaris arundinacea) are most likely native, based on SNPs (DArTseqLD)
The native vs. exotic status of reed canarygrass (RCG), a major invasive species of Minnesota wetlands, is unknown. The aim of this study was to investigate this native vs. exotic status to enhance its managem...

Variation Among Genotypes and Source Habitats in Growth and Fecundity of the Wetland Invasive Plant Phalaris arundinacea L
The spread of invasive wetland plants has resulted in a number of negative impacts to wetland habitats including reductions in biodiversity, displacement of native plants, and altered water flow. Phalaris arundin...

Population genetic structure of N. American and European Phalaris arundinacea L. as inferred from inter-simple sequence repeat markers
Phalaris arundinacea L. (reed canarygrass) has become one of the most aggressive invaders of North American wetlands. P. arundinacea is native to temperate N. America, Europe, and Asia, but repea...

The transmitting tissue of Nicotiana tabacum is not essential to pollen tube growth, and its ablation can reverse prezygotic interspecific barriers
The Nicotiana tabacum transmitting tissue is a highly specialized file of metabolically active cells that is the pathway for pollen tubes from the stigma to the ovules where fertilization occurs. It is thought to...

A novel pollen tube growth assay utilizing a transmitting tract-ablated Nicotiana tabacum style
Sexual plant reproduction requires multiple pollen–pistil interactions from the stigma (pollen adhesion, hydration, and germination) to the ovary (fertilization). Understanding the factors that regulate pollen...

Use of morphological, molecular markers and cytology to differentiate between closely related Gaura coccinea, G. drummondii for breeding purposes
Collection of wild species is critical to increase crop germplasm gene pools. Gaura coccinea has been identified as an important source of cold tolerance (winter hardiness) for hybridization with non-cold toleran...

Competive ability of invasive Miscanthus biotypes with aggressive switchgrass
Miscanthus (Miscanthus sinensis Anderss. [Poaceae]) is an ornamental and invasive grass native to Asia that has naturalized in several areas of the Middle Atlantic United States. Predicting how likely miscanthus ...

Epigenetic variation in tissue cultured Gaura lindheimeri
High levels of variability were observed in tissue cultured Gaura lindheimeri genotypes when flowered in situ. Tissue culture treatments for chromosome doubling (colchicine: 0, 0.25, 1.25 mM; trifluralin: 0, 15, ...

Statistical discrimination between pollen tube growth and seed set in establishing self incompatibility in Gaura lindheimeri 1
The University of Minnesota Gaura breeding program is develo** USDA Z3-4 winter-hardy genotypes via interspecific hybridization of G. lindheimeri (Z5-6) and G. coccinea (Z2-4). Prior to commencing interspecific...

Trifluralin-mediated polyploidization of Rosa chinensis minima (Sims) Voss seedlings
Many diploid rose species and cultivars possess valuable traits that can be introgressed into modern tetraploid cultivars. Interspecific, interploidy crosses are possible, but triploid hybrids typically have l...

Invasiveness in wetland plants in temperate North America
The spread of invasive taxa, includingLythrum salicaria, Typha × glauca, Myriophyllum spicatum, Phalaris arundinacea, andPhragmites australis, has dramatically changed the vegetation of many wetlands of North Ame...

Inheritance of pseudo-self compatibility in self-incompatible garden and greenhouse chrysanthemums, Dendranthema grandiflora Tzvelv
Self incompatibility (SI) can be used to alleviate costly hand emasculation and pollination in F1 hybrid chrysanthemum seed production. SI, however, disrupts the progression of inbreedig (selfing or full-sib mati...

Congruity backcrossing as a means of creating genetic variability in self pollinated crops: seed morphology of Phaseolus vulgaris L. and P. acutifolius A. Gray hybrids
Seeds of early generations of three reciprocal congruity-backcross (CBC) pedigrees, developed by backcrossing Phaseolus vulgaris-P. acutifolius hybrids to each of the parent species in alternate generations, exhi...

Style morph frequencies in Minnesota populations of Lythrum (Lythraceae)
Style morph frequencies (short∶mid∶long) were determined for a total of n = 11 918 plants in 16 Minnesota populations of Lythrum salicaria L. Nine populations were in the establishment phase, with population size...
