A study on the carotenoids of wild-type and mutant strains of the alga, Scenedesmus obliquus

Creator:: Williams, Janet Lynn
Abstract:: The primary objective of this thesis is to study, characterize and compare four types of Scenedesmus obliquus pigment mutants with the wild-type strain. The specific nature of the carotenoids synthesized in both heterotrophically and myxotrophically-grown cells, Hill reaction activity, photoreduction activity, and total photosynthetic activity of these cells are examined....

The effects of a mutation within vitamin E biosynthesis upon the development and function of the photosynthetic apparatus

Creator:: Sicher, Richard Charles
Abstract:: A new photosystem-II mutant of the green alga Scenedesmus obliquus D₃, strain PS-28, has been shown to lack a-tocopherol (vitamin E). The photosynthetic activity of dark grown samples of PS-28 is about 20% of the wild-type control. Culturing the mutant at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic activity...

Time effect of wild oat removal on winter wheat yield

Creator:: Abu-Irmaileh, Barakat Eid Ahmad
Abstract:: The extent of the competitive effect of wild oats on winter wheat yield was estimated in field studies on three commercial wheat farms in the Willamette Valley. The morphological development of the wild oat plants was also documented. Wild oats were removed from stands of wheat in six different treatments;...

Synthesis of the 2, 3, 3a, 8a-tetrahydro-2-hydroxy-furo [2, 3-b]benzofuran ring system, an aflatoxin moiety

Creator:: Jones, David James
Abstract:: A new method for the preparation of the 2, 3, 3a,8a-tetrahydro-2-hydroxyfuro[2, 3-b] benzofuran, XXX, ring system has been developed. The synthesis envolved a substitution reaction of phenol, XXIV, with 1-bromo-2, 5-hexadiene, XXV, to give 2, 5-hexadien-l -yl phenyl ether, XXVII. The ether was rearranged via an ortho-Claisen rearrangement to 3-(o-hydroxyphenyl)-l,...

Characteristics of two noncarotenogenic light sensitive mutants of Scenedesmus obliquus strain D₃

Creator:: Harvey, Geoffrey W.
Abstract:: Two light sensitive mutants of the green alga Scenedesmus obliquus strain D₃ have been characterized. The photodynamic nature of their sensitivity has been established, the subchloroplast site of photodamage has been investigated, and their noncarotenogenic character has been verified. The two mutants possess several similarities, although mutant L. S. -41...

Self concept : a comparison of four groups of university students

Creator:: Millikin, Norman Leo
Abstract:: The major purpose of this study was to determine if there were significant differences in the self-concepts of vocational education teacher-trainees, non-vocational education teacher trainees and non-education students at Montana State University. Two hundred students were surveyed to determine if there were any differences in self-concepts based on either major...
