The midget chromosome as a model to study cereal chromosome structureFrancki, Michael G. (Michael Gregory) January 1995 (has links) (PDF)
Bibliography: leaves 70-85. The aim of this study was to develop the midget chromosome as a model system to isolate structural elements from a cereal chromomsome. The midget is a diminutive chromosome found in wheat plants that contain a substituted rye cytoplasm.

Cellular and molecular aspects of cnidarian-algal associationsSchwarz, Jodi A. 18 October 2002 (has links)
Intracellular symbioses between cnidarians and dinoflagellates from the
genus Symbiodinium are widespread throughout the marine environment. These
associations are ecologically significant, especially in tropical waters where
symbiotic interactions between corals and Symbiodinium culminate in the
formation of limestone reefs. This thesis focuses on cellular and molecular aspects
of the symbiosis, specifically the initiation of the symbiosis and characterization of
a host gene, sym32, that is believed to function in the symbiosis. Sym32 was
originally identified as a differentially expressed protein in symbiotic vs.
aposymbiotic individuals of the sea anemone, Anthopleura elegantissima. Based
on its deduced amino acid sequence, sym32 belongs to a family of cell adhesion
proteins that play roles in cell recognition in a diverse array of organisms.
Chapter 2 examines the process by which a new cnidarian host acquires its
first symbionts. Larvae of the scleractinian coral Fungia scutaria, which are
initially aposymbiotic, acquired symbionts while feeding. Symbionts that entered
the larval gastric cavity with food were subsequently taken into host gastrodermal
cells by phagocytosis. Chapter 3 describes immunolocalization of sym32 in A.
elegantissima tentacles. In aposymbiotic tentacles, sym32 was localized to vesicles
within the host gastrodermal cells. Symbiotic tentacles lacked sym32-containing
vesicles. Instead, sym32 was present among the membranes that enclose the
symbionts within host cells. Western blots of proteins from Symbiodinium revealed
a 45/48kD doublet that cross-reacts with anti-sym32 antiserum. This suggests that
homologous proteins are expressed in both host (32kD) and symbiont (45/48 kD).
Chapter 4 describes the effects of environmental factors on expression of host
sym32. Aposymbiotic and symbiotic anemones maintained in continual darkness
for 3 weeks experienced a dramatic decline in sym32 protein levels, relative to
anemones maintained on a 12:12 h light:dark cycle. This suggests that light plays a
major role in regulating sym32. Exposure of anemones to elevated temperatures
for 2 days in the dark caused a mild bleaching response (expulsion of symbionts
from the host), but did not affect the levels of sym32 protein. Chapter 5 examines
the role of sym32 during the infection process, using antibody interference
techniques. F. scutaria larvae and symbionts incubated in sym32 antiserum during
the infection process experienced a decline in infection rates. Further, symbionts
that were incorporated into host gastroderm appeared to be degenerating in
antiserum treatments, but appeared to be healthy in preimmune controls. / Graduation date: 2003
