Systematics And Biogeography Of The Cortinarius Violaceus Group And Sequestrate Evolution In Cortinarius (Agaricales), Emma Harrower
Systematics And Biogeography Of The Cortinarius Violaceus Group And Sequestrate Evolution In Cortinarius (Agaricales), Emma Harrower
Doctoral Dissertations
Phylogenetics is a powerful tool used for illuminating the diversity of life on Earth, their evolution and their ecology. I created a multi-gene phylogenetic tree of Cortinarius section Cortinarius and uncovered five previously overlooked species, increasing the number of species in the section from seven to twelve. All members of the clade possess both cheilocystidia and pleurocystidia and possess a pigment known as (R)-39,49-dihydroxybphenylalanine. Ancestral state reconstruction estimated that the ancestral host was most likely an angiosperm, switching hosts when encountering novel host species in new lands, and only C. violaceus associating with the Pinaceae in North America. Biogeographic analysis …

Plant Pathology Faculty Publications
The family Rhabdoviridae consists of mostly enveloped, bullet-shaped or bacilliform viruses with a negative-sense, single-stranded RNA genome that infect vertebrates, invertebrates or plants. This ecological diversity is reflected by the diversity and complexity of their genomes. Five canonical structural protein genes are conserved in all rhabdoviruses, but may be overprinted, overlapped or interspersed with several novel and diverse accessory genes. This review gives an overview of the characteristics and diversity of rhabdoviruses, their taxonomic classification, replication mechanism, properties of classical rhabdoviruses such as rabies virus and rhabdoviruses with complex genomes, rhabdoviruses infecting aquatic species, and plant rhabdoviruses with both mono- …

Species Delimitation And Description Of Mesocriconema Nebraskense N. Sp. (Nematoda: Criconematidae), A Morphologically Cryptic, Parthenogenetic Species From North American Grasslands, Magdalena Olson, Timothy Harris, Rebecca Higgins, Peter Mullin, Kirsten Powers, Sean Olson, Thomas O. Powers
Department of Plant Pathology: Faculty Publications
Nematode surveys of North American grasslands conducted from 2010 to 2015 frequently recovered a species of criconematid nematode morphologically resembling Mesocriconema curvatum. These specimens were recovered from remnant native prairies in the central tallgrass ecoregion of North America, and not from surrounding agroecosystems. Historical records indicate that M. curvatum is a cosmopolitan species feeding on a wide range of agronomic and native plants. DNA barcoding indicates North American grasslands contain at least 10 phylogenetically distinct lineages of Mesocriconema that resemble, but are not, M. curvatum. Analysis of the two most common lineages reveals two distinctly different population structures. …

Systematic Studies On The Zygophyllaceae Of Saudi Arabia: New Combinationsin Tetraena Maxim., Dhafer Alzahrani, Enas Albokhari
Turkish Journal of Botany
During 2013 and 2014, fresh material of Tetraena hamiensis (Schweinf.) Beier & Thulin was collected from four different localities in Saudi Arabia. Some morphological differences, especially in leaf, flower parts, and fruit characters, were observed among individuals of this species within the same location. Principal coordinates analysis and the unweighted pair group method with arithmetic algorithm clustering test split off individuals of T. hamiensis with these morphological varieties as three clusters; one comprises individuals with characters overlapping those of T. hamiensis, one comprises individuals with characters overlapping those of T. qatarensis, and one comprises individuals with characters overlapping those of …

Anthostomelloides Krabiensis Gen. Et Sp. Nov. (Xylariaceae) From Pandanus Odorifer (Pandanaceae), Saowaluck Tibpromma, Dinushani Anupama Daranagama, Saranyaphat Boonmee, Itthayakorn Promputtha, Sureeporn Nontachaiyapoom, Kevin David Hyde
Turkish Journal of Botany
An Anthostomella-like taxon was obtained from Pandanus odorifer (Forssk.) Kuntze (Pandanaceae) collected in Krabi Province in Thailand. Morphological data plus phylogenetic analyses of combined ITS, LSU, RPB2, and β-tubulin sequence data clearly separate this Anthostomella-like taxon from other known genera in Xylariaceae. In this paper, we introduce this taxon as a new genus, Anthostomelloides, in the family Xylariaceae, with A. krabiensis as the type. A detailed morphological description, phylogenetic tree, photomicrographs of A. krabiensis, keys to Anthostomella-like genera, and a comparison of A. krabiensis with the morphologically similar taxa in Xylariaceae are provided.

A Taxonomic Study Of The Silene Sections Behenantha And Dichotomae (Caryophyllaceae) In Turkey Based On The Micromorphology Of Their Seed And Pollen, Mehmet Kuh, Kemal Yildiz, Ersi̇n Mi̇nareci̇
Turkish Journal of Botany
The seed and pollen grain micromorphologies of 10 taxa of the Silene sections Behenantha and Dichotomae (Caryophyllaceae) were analyzed in this study. Although the seeds of the analyzed taxa were generally reniform, S. tenuiflora and S. koycegizensis from the section Behenantha were clearly distinct from other taxa, while subspecies of S. dichotoma and S. euxina in the section Dichotomae showed differences. Pollen grains are periporate and spheroidal and ornamentation is generally spinulate-microperforate in all taxa. However, ornamentation is spinulate in S. euxina and semireticulate in S. koycegizensis. While the exine structure is generally tectate, it is semitectate in S. koycegizensis. …

Peucedanum Guvenianum (Apiaceae), A New Species From West Anatolia, Turkey, Hasan Yildirim, Hayri̇ Duman
Turkish Journal of Botany
Peucedanum guvenianum Yıldırım & H.Duman is described as a species new to science. It is endemic to the West Anatolia region of Turkey. It is known from a single locality in İzmir Province. P. guvenianum shows similarities to P. longifolium, P. ruthenicum, and P. vourinense. Diagnostic morphological characters are discussed and compared with those of closely related taxa. It is easily distinguished from related species especially by its stem 130-220 cm tall, distinctly striate, densely branched from below the middle to upper part; basal leaves 28-40 cm long and 20-70 cm wide; bracts linear-lanceolate and erect; petals emarginate at apex; …

Taxonomic Position Of Abies Equi-Trojani On The Basis Of Needlecharacters By Comparison With Different Fir Species, Anna Katarzyna Jasinska, Katarzyna Sekiewicz, Tolga Ok, Angel Romo, Adam Boratynski, Krystyna Boratynska
Turkish Journal of Botany
The needles from 25 trees of Abies equi-trojani from Kazdağı (Mount Ida) were compared with those from four populations of A. alba, two of A. cephalonica, and three of each of A. xborisii-regis, A. bornmuelleriana, and A. nordmanniana, each represented by 29-31 individuals. Thirty-nine morphological and anatomical needle characters (26 main and 13 estimated ones) were examined biometrically to verify the systematic position of A. equi-trojani. To evaluate the relationships among taxa, Student's t-test for independent samples, the Mann-Whitney U test, and discrimination and clustering analyses were applied. The differences between taxa were statistically significant for several characters, but the …
Taxonomy Of Poa Jubata And A New Section Of The Genus (Poaceae), Evren Cabi̇, Robert John Soreng, Lynn Gillespie
Taxonomy Of Poa Jubata And A New Section Of The Genus (Poaceae), Evren Cabi̇, Robert John Soreng, Lynn Gillespie
Turkish Journal of Botany
Poa jubata A.Kern. is an ephemeral, southeastern European species of which little is known. A molecular phylogenetic analysis of Poa L., including all previously identified major lineages, shows this species to be isolated, with a genotype here designated as J (plastid) j (nrDNA). It is assigned to the monotypic P. sect. Jubatae sect. nov. The section is differentiated from other Poa sections in having 5-nerved upper glumes, very narrow palea flanges, an annual habit, and erect solitary culms. Poa jubata occurs along coastal regions of the Balkans and is rather rare. Two new collections were made in 2015 in Thrace, …

Lectotypifications Of Cerastium Siculum, C. Densiflorum, And C. Aggregatum,And Taxonomic Notes On C. Siculum (Caryophyllaceae), Sebastien Traclet, Mathias Pires, Gianniantonio Domina
Turkish Journal of Botany
Nomenclatural notes on Cerastium siculum Guss. (Caryophyllaceae), a species described from Sicily and occurring in the central western region of the Mediterranean basin, are discussed. The names C. aggregatum Durieu ex Brign., C. densiflorum Guss., and C. siculum are lectotypified here. The taxonomic independence of C. siculum from C. semidecandrum L. and the other taxa of Cerastium L. sect. Orthodon Ser. subsect. Fugacia Fenzl is confirmed, as well as the synonymy of C. aggregatum and C. densiflorum.
