Use of simultaneous analyses to guide fossil-based calibrations of Pinaceae phylogeny

Creator:: Gernandt, David S., Magallon, Susana, Lopez, Gretel Geada, Flores, Omar Zeron, Willyard, Ann, and Liston, Aaron
Abstract:: Uncertainties in the age and phylogenetic position of Pinaceae fossils present significant obstacles to our understanding of the timing of diversification in the family. We demonstrate that simultaneous phylogenetic analyses of chloroplastDNA(matK and rbcL) and nonmolecular characters that include both extant genera and a limited number of fossil taxa provide...

Phylogenetic insights into the correlates of dioecy in meadow-rues (Thalictrum, Ranunculaceae)

Creator:: Soza, Valerie L., Brunet, Johanne, Liston, Aaron, Smith, Patricia Salles, and Di Stilio, Veronica S.
Abstract:: Numerous studies have examined the evolution of sexual systems in angiosperms, but few explore the interaction between these and the evolution of pollination mode. Wind pollination is often associated with unisexual flowers, but which evolved first and played a causative role in the evolution of the other is unclear. Thalictrum,...

The biogeography of Plantago ovata Forssk. (Plataginaceae)

Creator:: Meyers, Stephen and Liston, Aaron
Abstract:: Plantago ovata Forssk. (Plantaginaceae) is a species that, in North America, inhabits desert and Mediterranean habitats of the southwest United States, northwest Mexico, and the Channel Islands of California and Mexico. In the Eastern Hemisphere, P. ovata inhabits desert regions ranging from the Canary Islands, across northern Africa to India....

An Evaluation of Putative Sympatric Speciation within Limnanthes (Limnanthaceae)

Creator:: Meyers, Stephen C., Liston, Aaron, and Meinke, Robert
Abstract:: Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies within Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...

Separating the wheat from the chaff: mitigating the effects of noise in a plastome phylogenomic data set from Pinus L. (Pinaceae)

Creator:: Parks, Matthew, Cronn, Richard, and Liston, Aaron
Abstract:: Background: Through next-generation sequencing, the amount of sequence data potentially available for phylogenetic analyses has increased exponentially in recent years. Simultaneously, the risk of incorporating ‘noisy’ data with misleading phylogenetic signal has also increased, and may disproportionately influence the topology of weakly supported nodes and lineages featuring rapid radiations and/or...

Creator:: DeGiorgio, Michael, Syring, John, Eckert, Andrew J., Liston, Aaron, Cronn, Richard, Neale, David B., and Rosenberg, Noah A.
Abstract:: BACKGROUND: As it becomes increasingly possible to obtain DNA sequences of orthologous genes from diverse sets of taxa, species trees are frequently being inferred from multilocus data. However, the behavior of many methods for performing this inference has remained largely unexplored. Some methods have been proven to be consistent given...

Phylogenetic marker development for target enrichment from transcriptome and genome skim data: the pipeline and its application in southern African Oxalis (Oxalidaceae)

Creator:: Schmickl, Roswitha, Liston, Aaron, Zeisek, Vojtěch, Oberlander, Kenneth, Weitemier, Kevin, Straub, Shannon C. K., Cronn, Richard C., Dreyer, Léanne L., and Suda, Jan
Abstract:: Phylogenetics benefits from using a large number of putatively independent nuclear loci and their combination with other sources of information, such as the plastid and mitochondrial genomes. To facilitate the selection of orthologous low‐copy nuclear (LCN) loci for phylogenetics in nonmodel organisms, we created an automated and interactive script to...

Reconciling Conflicting Phylogenies in the Origin of Sweet Potato and Dispersal to Polynesia

Creator:: Muñoz-Rodríguez, Pablo, Carruthers, Tom, Wood, John R.I., Williams, Bethany R.M., Weitemier, Kevin, Kronmiller, Brent, Ellis, David, Anglin, Noelle L., Longway, Lucas, Harris, Stephen A., Rausher, Mark D., Kelly, Steven, Liston, Aaron, and Scotland, Robert W.
Abstract:: The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that remained unanswered. Our...

Bioclimatic, ecological, and phenotypic intermediacy and high genetic admixture in a natural hybrid of octoploid strawberries

Creator:: Salamone, Isabella, Govindarajulu, Rajanikanth, Falk, Stacey, Parks, Matthew, Liston, Aaron, and Ashnam, Tia-Lynn
Abstract:: Premise of the Study: Hybrid zones provide "natural laboratories" for understanding the processes of selection, reinforcement, and speciation. We sought to gain insight into the degree of introgression and the extent of ecological-phenotypic intermediacy in the natural hybrid strawberry, Fragaria x ananassa subsp. cuneifolia. Methods: We used whole-plastome sequencing to...

Abstract:: We studied the natural hybrid (Fragaria ×ananassa subsp. cuneifolia) between two sexually dimorphic octoploid strawberry species (F. virginiana and F. chiloensis) to gain insight into the dynamics of sex chromosomes and the genesis of sexual dimorphism. Male sterility is dominant in both the parental species and thus will be inherited...
