Characterizing the Genetic Variation in Seven Species of Deciduous Native Azaleas and Identifying the Mechanism of Azalea Lacebug Resistance in Deciduous Azalea
CHARACTERIZING THE GENETIC VARIATION IN SEVEN SPECIES OF DECIDUOUS NATIVE AZALEAS AND IDENTIFYING THE MECHANISM OF AZALEA LACEBUG RESISTANCE IN DECIDUOUS AZALEA by MATTHEW RANDOLPH CHAPPELL (Under the direction of Dr. Carol Robacker) ABSTRACT Despite the ecologic and economic importance of native deciduous azaleas (Rhododendron spp. section Pentanthera), our understanding of interspecific variation of North American deciduous azalea species is limited. Furthermore, little is known concerning intraspecific or interpopulation genetic variation. The present study addresses questions of genetic diversity through the use of amplified fragment length polymorphism (AFLP) analysis. Twenty-five populations of seven species of native azalea were analyzed using three primer pairs that amplified a total of 417 bands. Based on analysis of molecular variance (AMOVA) and estimates of Nei’s coefficients of gene diversity (HS, HT, and GST), the majority of variation in deciduous azalea occurs within populations. Both among species and among population variation was low, likely the effect of common ancestry as well as frequent introgression among members (and populations) of section Pentanthera. The majority of populations were grouped into species based on Nei’s unbiased genetic distances viewed as a UPGMA phenogram. The significance of these results is discussed in relation to breeding in section Pentanthera. In addition to the lack of information concerning genetic variation in North American native azaleas, little is known concerning the insect-plant interaction between the primary azalea pest in the United States, azalea lace bug (ALB) (Stephanitis pyrioides Scott), and deciduous azalea. Azaleas are largely resistant to predation by insects, with the exception of ALB. Within deciduous azalea (Rhododendron section Pentanthera) varying levels of resistance to ALB is observed with a continuous distribution from susceptible to highly resistant. -

A Basic Requirement for Studying the Heavens Is Determining Where In
Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short). -

Gies December 15, 1992 - September 30, 1995 Center for High Angular Resolution Astronomy Department of Physics and Astronomy Georgia State University Atlanta, GA 30303-3083 NASA International Ultraviolet Explorer Observatory Grant NAG 5-2148 1. Project Summary This grant was awarded in support of an observational study with the NASA [UE Observatory during the 15th episode (1992), and it subsequently also supported our continuing work in 16th (1994) and 18th (1995) episodes. The project involved the study of FUV spectra of massive spectroscopic binary systems containing hot stars of spectral type O. We applied a Doppler tomography algorithm to reconstruct the individual component UV spectra of stars in order to obtain improved estimates of the temperature, gravity, UV intensity ratio, and projected rotational velocity for stars in each system, and to make a preliminary survey for abundance anomalies through comparison with standard spectra. We also investigated the orbital phase-related variations in the UV stellar wind lines to probe the geometries of wind-wind collisions in these systems. The project directly supported two Ph.D. dissertations at Georgia State University (by Penny and Thaller), and we are grateful for this support. No inventions were made in the performance of this work. Detailed results are summarized in the abstracts listed in the following section. 2 2. Bibliography • Gies,D. R., Mason,B. D., Hartkopf, W.

Studies on the Chemistry of Australia's Native Fauna and Flora
Studies on the chemistry of Australia's native flora and fauna My first involvement in natural products chemistry was during my Honours year in chemistry at UNSW in 1964 where, like so many other chemists before me, I set to work on my bag of sawdust obtained from some Australian tree to find out what organic compounds could be extracted from it. The species involved was Sophora tomentosa and under the supervision of Associate Professor Ron Eade I obtained some isoflavone and pterocarpin derivatives. That experience whetted my interest in the chemicals contained living systems and sparked an interest in why they were there. Sophora tomentosa is a member of the Leguminosae and it is only within this family that isoflavones had been found. The work described in this thesis has been carried out at the School of Chemistry, University of New South Wales over a period of, approximately, 25 years. During this time at the University I have been responsible for providing the routine mass specti'ometry service within the School of Chemistry, though the work described herein is not part of that work. GC/MS was initiated within the School in 1969. In 1970, as a postdoctoral fellow, I used the technique for the first time in the my work on insect chemistry. After a period of 5 years at Monash University I returned to UNSW in 1976 to run the routine mass spectrometry service. My involvement with insect chemistry continued and several years later I commenced work on essential oils chemistry. Like a lot of other people who spend their lives in doing chemical research, I got into essential oils research more or less by accident, though in my case this accident was once removed. -
