Microsatellite marker development and molecular characterization in highbush blueberry (Vaccinium corymbosum L.) and Vaccinium species

Creator:: Boches, Peter
Abstract:: Pre-existing Expressed Sequence Tag (EST) libraries (1,305 sequences) and a newly constructed microsatellite-enriched genomic library (136 clones) from the V. corymbosum cultivar 'Bluecrop' were screened for unique Simple Sequence Repeat (SSR)-containing sequences. Our goal was to develop a set of robust SSR markers for use in managing the National Clonal...

Molecular cloning and characterization of the diageotropica gene in tomato (Lycopersicon esculentum Mill.)

Creator:: Oh, KwangChul
Abstract:: The auxin-resistant diageotropica (dgt) mutant of tomato (Lycopersicon esculentum Mill.) has a pleiotropic phenotype including a lack of lateral roots and reduced gravitropic response, apical dominance, vascular development, and fruit growth. The dgt mutation reduces the auxin sensitivity of only a subset of auxin responses while levels, metabolism, and transport...

Small RNA pathways in plants

Creator:: Montgomery, Taiowa A.
Abstract:: miRNA-guided cleavage initiates entry of primary transcripts into the trans-acting siRNA (tasiRNA) biogenesis pathway involving RNA-DEPENDENT RNA POLYMERASE6 (RDR6), DICER-LIKE 4 (DCL4), and SUPPRESSOR OF GENE SILENCING3 (SGS3). Arabidopsis thaliana TAS1 and TAS2 families yield tasiRNA that form through miR173- guided initiation cleavage on the 5’ side of the siRNA-generating...

Systematics of Pacific Northwestern species of the genus Gymnomyces inferred from nuclear ribosomal DNA internal transcribed spacer sequences

Creator:: Whitbeck, Kristen L.
Abstract:: Gymnomyces is an ectomycorrhizal basidiomycete genus in the family Russulaceae estimated to contain less than 50 species worldwide, with 23 species known to occur in the Pacific Northwest. Gymnomyces species are common in Pacific Northwest forests that include Pseudotsuga, Abies, Tsuga, and Quercus. They produce sequestrate (truffle-like) sporocarps with ornamented...

Molecular mechanism of germination of Clostridium perfringens spores

Creator:: Paredes-Sabja, Daniel
Abstract:: Clostridium perfringens is the causative agent of a wide variety of diseases in animals and humans. C. perfringens can produce more than 15 toxins. However, individual strains produce a subset of these toxins. Although a small percentage of C. perfringens isolates (mostly belonging to type A) produce C. perfringens enterotoxin...

Species identification of Klamath Basin suckers (Pisces : Catostomidae) and an assessment of hybridization using anonymous nuclear loci

Creator:: Wagman, David Wolfe
Abstract:: Low copy number anonymous nuclear loci were used to search for species markers in four species of Klamath Basin suckers. We sequenced 28 randomly chosen loci representing 10,421 bp; 21 loci were similar to sequences in GenBank. Eight fixed sequence differences were found among Klamath species. Locus 120 contained rare...

Comparison of Octopus dofleini hemocyanin paralogues and evidence for recent divergence

Creator:: van Olden, Erin K.
Abstract:: Presented here is an in depth comparison of the Octopus dofleini hemocyanin paralogues, designated A and G. The protein sequences coded by these genes are each comprised of seven oxygen-binding units, or functional units (FU-a to FU-g). Each FU is approximately 400 amino acids in length and a linker region...

Mechanisms for the interaction of environmental mycobacteria with host cells

Creator:: Harriff, Melanie J.
Abstract:: Environmental mycobacteria are important opportunistic pathogens for many hosts, including humans, cattle, and fish. Two well-studied species are Mycobacterium avium subsp. avium, a significant cause of disseminated bacterial disease in patients with AIDS, and Mycobacterium avium subsp. paratuberculosis, the cause of Johne’s disease in cattle. Many other species that are...

Analysis of Bacteroidales 16S rRNA gene sequences from a geographically isolated human population

Creator:: Petersen, Carolyn A.
Abstract:: Standard methods of measuring fecal pollution in water do not distinguish between human and non-human sources. Molecular technology enabled the development of host-specific markers that distinguish fecal sources. Human specific PCR primers, HF183F and HF134F, were designed based on phylogenetic analyses of partial 16S rRNA gene sequences from the Bacteroidales...

The influence of parasite ecology on the genetic structure of parasite populations

Creator:: Criscione, Charles David
Abstract:: Parasites are unique study organisms for evolutionary ecologists. Yet, molecular ecology studies on parasites have lagged far behind those on free-living organisms. The goal of the review in Chapter 2 was to illustrate areas of research that may be of particular interest in relation to the parasitic life style and...
