Characterization Of The Granule-Bound Starch Synthase I Gene In Chenopodium, Douglass C. Brown

Theses and Dissertations

Chenopodium L. is a relatively under-studied genus that includes the cultivated seed crop quinoa (Chenopodium quinoa Willd.). Quinoa is an allotetraploid (2n=4x=36, AABB genomes) that is cultivated by subsistence farmers and commercial growers in the Andean regions of South America. Approximately 60% of a quinoa seed is starch, a glucose polymer that is an important carbohydrate energy source in the human diet. Seed starch is normally comprised of amylose and amylopectin in a 1:3 ratio, but starches with different amylose:amylopectin ratios have different properties and potential uses. The accumulation of the amylose fraction of starch is controlled by a single …

Botanists In The Canyonlands Of The Colorado Plateau – 1950–1983 & Prior, Stanley L. Welsh, Glen Moore

Books by Faculty of the Monte L. Bean Life Science Museum

Abstract

This paper provides an overview of botanical investigations in southeastern Utah, but is not so-restricted geographically. It grew out of the discovery of decades-old manuscripts on the flora of what became Canyonlands National Park in 1964, but from those typescript copies the coverage grew outward geographically and backward in time to the earliest inhabitants of what is today known as the Four Corners Region of the American Southwest. Reviewed is the account of utilization of the region and its natural resources by aboriginal inhabitants who were familiar with all of it. That early, and to an extent, continuous occupation …

Society Islands: Tahiti, Raiatea, Huahine, Bora Bora, Maupiti, French Polynesia, Stanley L. Welsh

Books by Faculty of the Monte L. Bean Life Science Museum

This account details five trips to the Society Islands and the plants collected there, along with the author’s personal experiences during those years. The resulting publication that aids in Society Island plant identification is Flora Societensis. Welsh and his wife became acquainted with the islands through a Tahitian girl that lived with them for a few years, and who they kept in contact with for years after. The Welshes were invited to Tahiti through these connections, and thus the following research and adventures occurred. The account includes details of island culture along with descriptions of species found there. Plant …
