Eyespot Assembly and Positioning in Chlamydomonas reinhardtii
The eyespot of the biflagellate unicellular green alga Chlamydomonas reinhardtii is a complex organelle that facilitates directional responses of the cell to environmental light stimuli. The eyespot, which assembles de novo after every cell division and retains a distinctive association with the …

THE EVOLUTION OF PHENOTYPIC PLASTICITY IN BUTTERFLIES
… proximate mechanisms of temperature-induced eyespot size plasticity across homologous eyespots in one species of Nymphalid butterfly, Bicyclus anynana. Investigations in this thesis conclude that sex- specific differences in 20-hydroxyecdysone (20E) hormone titers lead to sexually dimorphic …

Cloning of a <i>CHLAMYDOMONAS REINHARDTII</i> Marker into a RNA Interference Construct to Test Whether the Photoreceptor Chlamyrhodopsin Is Involved in Circadian Clock Resetting
… Chlamyrhodopsin (COP), the most abundant eyespot protein, was reported to have no role in the phototactic and photophobic responses in <i>C. reinhardtii</i>. Its function is yet unknown. <br> In the present study, we hypothesized that the function of COP is to mediate entrainment of the …

Brachypodium distachyon as a genetic model pathosystem to study resistance against fungal pathogens of small grain cereals
… of small-grain cereals causing ramularia, eyespot and take-all diseases. In Chapter 4, a preliminary study of Bd T-DNA mutant lines altered in phytohormone biosynthesis or response investigates alteration of Fusarium resistance. Mutation of the main brassinosteroid (BR) receptor (BRI1) was …

Studies on sweet corn: Stewart's wilt forecasting, the effect of maize dwarf mosaic on foliar diseases, and herbicide sensitivity
… leaf spot (GLS), Diplodia leaf streak (DLS), and eyespot. Among MDM-susceptible hybrids, mean severity ratings of SCLB, NCLS, GLS, DLS, and eyespot on MDM-infected plants typically were double those of virus-free plants. Three diseases not substantially increased by MDM-infection included: common …

Cytology and ultrastructure of eustigmatophyceae
… at basal body B2 and curves around the eyespot. For comparison, zoospores of the tribophycean species Heterococcus marietanii and H. protonematoldes were also studied. A system of flagellar roots consisting of a small rhizoplast and three microtubular roots, two directed anteriorly and …

Bioenergetics and dynamics of ciliary responses and systems biology of phototaxis in Chlamydomonas reinhardtii
… called rhodopsin, which overlays the eyespot. The organism makes decisions to swim toward, away from, perpendicular to or to ignore the light using its slender arm-like structures called cilia. It can integrate several external inputs such as ion concentration and light intensity, and …
