"Big bud" disease of filbert : a descriptive cytological study of the affected plant tissues

Creator:: Larew, Hiram, 1953-
Abstract:: A light and electron microscope study of Corylus avellana L. vegetative buds infested with the eriophyoid mites, Cecidiophyopsis vermiformis Nal. and Phycoptella avellanae Nal., is reported. Descriptions are given of changes in infested stipule tissue. The nipple-like proliferations (enations) which arise on the infested stipule surface are covered by a...

A biosystematic study in the genus Aster, section Aster, in western North America

Creator:: Dean, Milton Lee
Abstract:: A biosystematic investigation was undertaken in 15 species and three subspecies of the genus Aster, in western North America. Previous studies had been based entirely on external morphological features, and it was believed that much could be learned about the natural affinities of the taxa by exploring their cytological and...

A chemosystematic study of the phylogenetic position of Arabidopsis thaliana (L.) heynh. (Brassicaceae) employing numerical methods

Creator:: Kaplan, Hesh J.
Abstract:: The Brassicaceae, Mustard Family, is a well marked natural family, whose tetramerous flowers, tetradynamous stamens, and distinctive bi- carpellary fruits, clearly distinguish it from related families. It is a large family of some 3, 000 recognized species and over 300 genera. Although numerous attempts have been made over the past...

A comparative study of temperate Chamaecyparis forests

Creator:: Hawk, Glenn M.
Abstract:: The objectives of this study include: (1) analysis of Chamaecyparis lawsoniana, C. taiwanensis, and C. formosensis forests including the structure, composition, and dynamics of plant communities and their environmental relationships; and (2) comparison of the temperate Chamaecyparis forests of Taiwan and the Pacific Northwest with emphasis on structural and successional...

A fistful of Astragalus : phenotypic and genotypic basis of the most taxon rich species in the North American flora

Creator:: Knaus, Brian J.
Abstract:: The study of the infra-specific ranks (i.e., subspecies and variety) can be considered the study of the process of speciation. Astragalus lentiginosus Douglas ex Hooker (Fabaceae) is the most taxon rich species in the U.S. flora currently including 40 taxonomic varieties. These varieties were described using traditional taxonomic methods primarily...

A G-type Lectin Receptor-like Kinase Associated with Septoria Canker Resistance and Susceptibility Described using Multi-omics and Biotechnology

Creator:: Lenz, Ryan R.
Abstract:: Managers of forest and plantation ecosystems are encountering growing problems involving plant pathogens and the expanding geographic ranges of these pathogens. Historically unexposed stands are exceptionally vulnerable when a non-native pathogen is introduced because these pathogens can cause devastating disease in a host population that lacks co-evolved resistance mechanisms. One...

A Lower Cretaceous (Valanginian) seed cone provides the earliest fossil record for Picea (Pinaceae)

Creator:: Klymiuk, Ashley A. and Stockey, Ruth A.
Abstract:: Premise of study: Sequence analyses for Pinaceae have suggested that extant genera diverged in the late Mesozoic. While the fossil record indicates that Pinaceae was highly diverse during the Cretaceous, there are few records of living genera. This description of an anatomically preserved seed cone extends the fossil record for...

A Perithecial Sordariomycete (Ascomycota, Diaporthales) from the Lower Cretaceous of Vancouver Island, British Columbia, Canada

Creator:: Bronson, Allison W., Klymiuk, Ashley A., Stockey, Ruth A., and Tomescu, Alexandru M. F.
Abstract:: A perithecial ascomycete, Spataporthe taylori gen. et sp. nov., represented by >70 sporocarps is preserved by cellular permineralization in marine carbonate concretions dated at the Valanginian-Hauterivian boundary (Early Cretaceous) from Vancouver Island, British Columbia, Canada. The spheroid perithecia with lumina 330–470 µm wide and 220–320 µm high are densely distributed...
