Factors affecting germination of endomycorrhizal spores

Creator:: Daniels, Barbara Ann
Abstract:: Four isolates of Glomus mosseae, collected from diverse geographic locations, were pot cultured on varied host plants or stored in the same soil as collected. Spores of three isolates failed to germinate on any of five agar media while the fourth germinated well on all media. Lack of germination on...

Study of seed germination-associated genes using Arabidopsis enhancer-trap

Creator:: Liu, Po-Pu
Abstract:: In mature Arabidopsis seeds, the testa (seed coat) is no longer a living tissue. Thus, major sites of gene expression in imbibed seeds are the internal living tissues such as the embryo and the endosperm. To elucidate the molecular mechanisms of seed germination, the gene regulation in these two tissues...

Changes in enzyme activities of the isoprenoid pathway in germinating Pisum sativum

Creator:: Green, Terrence Robert, 1944-
Abstract:: The nature of the isoprenoid pathway and diversity of biologically significant products suggests that the pathway may be highly regulated, particularly under stress conditions, where the availability of high energy intermediates is limited. It was postulated that germinating seeds suffer from a limited supply of available energy and must therefore...

Full Text:: germination in Pisum sativum confirmed that P-amyrin (triterpene) and P-sitosterol (sterol) are sequentially

New Insights into the Molecular Mechanism of Clostridium perfringens Spore Germination

Creator:: Banawas, Saeed S.
Abstract:: C. perfringens is a spore-forming, gram-positive, anaerobic pathogenic bacterium capable of causing a wide variety of diseases in both humans and animals. However, the two most common illnesses in humans are C. perfringens type A food poisoning (FP) and non-food-borne (NFB) gastrointestinal (GI) illnesses. Interestingly, these two major diseases are...

Physical factors affecting longevity and germination of seed of Western dwarfmistletoe (Arceuthobium campylopodum Engelm. f. campylopodum)

Creator:: Beckman, Kent Mardsen
Abstract:: Longevity and germination of seed of western dwarfmistletoe (Arceuthobium campylopodum Engelm. f. campylopodum) of ponderosa pine (Pinus ponderosa Laws.) was investigated to determine: 1) the influence of humidity and temperature on seed viability and deterioration during storage; 2) the physiology of seed dormancy; 3) the composition of seed reserve food...

The effects of abscisic acid on gene expression during wheat germination

Creator:: Ballo, Barbara
Abstract:: Germination of immature (Stage III) and mature (Stage V) wheat (Triticum aestivum L. var. Chinese Spring and Yamhill) embryos is prevented by the inclusion of 10⁻⁴ M abscisic acid (ABA) in culture medium. In addition, Stage III embryos develop into mature embryos in culture medium containing ABA. In the absence...

Clostridium perfringens spores : inactivation, germination, and formation

Creator:: Udompijitkul, Pathima
Abstract:: The enterotoxin-producing Clostridium perfringens type A isolates are responsible for the third most common foodborne illness in the United States and can also cause non-foodborne human gastrointestinal (GI) diseases such as antibiotic- associated and sporadic diarrheas. Three important factors contribute to the ability of C. perfringens to cause GI diseases,...

Seed dormancy in domesticated and wild sunflowers (Helianthus annuus L.) :types, longevity and QTL discovery

Creator:: Brunick, Robert L.
Abstract:: Elite inbred sunflower (Helianthus annuus L.) lines were found to have short-lived embryo and seed covering dormancies. Seed dormancy of wild sunflowers (H. annuus, H. argophyllus and H. exilis) was found to be controlled primarily by the seed covering (seed coat and pericarp) and embryo dormancy was short-lived (four to...
