Genetic Structure Of Pseudoroegneria Spicata In The Northern Palouse Prairie And Channeled Scablands, Ethan Timothy Bean
EWU Masters Thesis Collection
Establishing genetically diverse communities that can adapt to dynamic selective pressures is crucial in ecological restoration. However, the genetic structure of native plant species used for restoration is often poorly understood. Pseudoroegneria spicata, is a keystone species of the Inland Northwestern US that has become a staple in commercially available restoration seed mixes. It is abundant in remnant prairies of the endangered Palouse Prairie ecoregion, which is characterized by rolling hills of deep loess soil. Less than 1% of native Palouse Prairie is left, due to agricultural conversion, with remnants highly fragmented and isolated. P. spicata is also common in …

Turkish Journal of Botany
Onosma L., the largest genus of Boraginaceae, is represented by 105 species in Turkey with an endemism rate of 52%. Phytochemical studies indicate that Boraginaceae plants mainly comprise naphthoquinones with a wide range of biological activities including anticancer, antiinflammatory, wound healing, and antioxidant effects. However, few taxa of the genus Onosma have been investigated in detail for their bioactivities. Considering the high rate of endemism and an inadequate number of bioactivity screening studies in literature, we aimed to evaluate the cytotoxic effects and topoisomerase inhibitory activities of some Onosma species growing in southwestern Turkey. Here, we describe a comprehensive cytotoxic …

The Systematics Of Physaria Sensu Stricto From Wyoming And Surrounding Areas, Jason Ratcliff
Dissertations and Theses @ UNI
Two genera of Brassicaceae – Lesquerella and Physaria – were recently united on the basis of monophyly. Classically, these genera have been distinguished based on morphology with 'traditional” Physaria species having doubly inflated (didymous) fruits. Molecular data consisting of ribosomal internal transcribed spacer (ITS) DNA sequences indicate Physaria has evolved from the larger Lesquerella genus, thus making Lesquerella a paraphyletic grouping as previously described. A revised treatment of the combined Physaria recognized 106 species within the genus, of which 26 taxa occur in Wyoming. Of the Wyoming taxa, those traditionally described as belonging to Physaria (i.e.Physaria sensu stricto) have …

Climate Niche Evolution In C4+Cam Portulaca And Closely Related C3+Cam Lineages, Nora M. Heaphy
Library Map Prize
With at least a hundred independent origins among land plants, the CAM and C4 photosynthetic pathways represent one of the most notable examples of global convergent evolution of a complex trait. While biochemically similar, CAM and C4 are generally understood to be two distinct ecological adaptations evolving along separate trajectories. However, the purslanes (Portulaca), a globally widespread clade of around 100 species of annual and perennial succulents, are able to operate both CAM and C4 cycles in the same leaf. Portulaca likely originated from a facultative CAM ancestor and then evolved a C4 system at least three times …
