The Physiological Effects of Phycobilisome Antenna Modification on the Cyanobacterium Synechocystis sp. PCC 6803

Phycobilisomes are the large, membrane extrinsic light harvesting antenna of cyanobacteria. They function to absorb light energy and deliver it efficiently to the photosystems, thereby increasing photosynthetic light absorption. Wild type phycobilisomes in the model organism Synechocystis sp. PCC 6803: Synechocystis 6803) consist of a tricylindrical core from which six rods radiate. The colored phycobiliproteins are held together by colorless linker polypeptides. Several phycobilisome truncation mutants have been generated in Synechocystis 6803. The first, CB, has truncated phycobilisome rods; the second, CK, has only the phycobilisome core; and the third, PAL, has no phycobilisomes at all. Together, these mutants construct a series of increasingly truncated phycobilisomes which are useful for studying the physiology of antenna truncation in cyanobacteria. In this dissertation, the physiological effects of antenna truncation are examined from three perspectives. First, the effect of partial and complete phycobilisome removal on the expression and activity of photosystem II is examined using a variety of assays that center around fluorescence and oxygen evolution. Second, the overall effects of antenna truncation on thylakoid membrane spacing and structure is explored using electron microscopy and small angle neutron scattering. Finally, the effects of antenna truncation on culture-wide biomass productivity are examined in a variety of setting, including a bench-scale photobioreactor. Together, these studies represent a comprehensive examination of the physiological effects of antenna truncation on Synechocystis 6803

Sound-induced micromechanical motions in an isolated cochlea preparation

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2006.Includes bibliographical references (p. 44-45).The mechanical processes at work within the organ of Corti can be greatly elucidated by measuring both radial motions and traveling-wave behavior of structures within this organ in response to sound stimuli. To enable such measurements, we have developed a new preparation for observing three-dimensional motions of micromechanical structures in the apical region of an isolated gerbil cochlea. The cochlea is submerged in a low-chloride, low-calcium artificial perilymph solution and cemented to the bottom of a Petri dish at an angle. The bone above scala vestibuli of one half of the apical turn is removed to allow optical imaging with a 40x, 0.8 NA water-immersion objective. Reissner's membrane is left intact. Illumination is provided with a blue LED coupled to an optical fiber. The fiber is positioned next to the bone surrounding scala tympani of the apical turn, so that the organ of Corti is illuminated from below. The resulting optical access allows imaging of a variety of structures that have been proposed to play a role in cochlear mechanics, including inner and outer hair cell bundles, the tectorial membrane, inner and outer pillar cells, and efferent fibers in the tunnel of Corti. In some preparations, individual stereocilia of inner hair cell bundles can be resolved.(cont.) Motions are stimulated by driving the stapes with a piezoelectric probe, and are measured using a stroboscopic computer microvision system. Measurements of sub-micrometer motions of key structures in three dimensions are quantified, including longitudinal motion of the organ of Corti and relative radial motion between the tectorial membrane and hair cells. Longitudinal motion of the Efferent fibers in the tunnel of Corti is found to have a phase lead with respect to the hair cell bodies. This system enables quantitative studies of both the relative motions of structures within the organ of Corti in response to sound and the propagation of traveling waves along structures within the organ of Corti.by Scott Lawrence Page.S.M
