  1. The Control of Spore Germination in Anemia Phyllitidis (L.) Swartz and Other Ferns

    Weinberg, Eric S

    <p>Many fern spores require light for germination. In one family of ferns, the Schizaeaceae, the gibberellins overcome this light requirement and induce dark-germination. Fern gametophytes produce antheridium-inducing substances. The Anemia substance, antheridogen-B, is demonstrated to induce …

  2. Characterization of the Bacillus anthracis SleL Protein and its Role in Spore Germination

    Lambert, Emily AnneVirginia Tech2010

    Bacillus anthracis is a spore-forming bacterium that is included on the list of select agents compiled by the Centers for Disease Control. When a B. anthracis spore germinates, a protective layer of peptidoglycan known as the cortex must be depolymerized by germination-specific lytic enzymes …

  3. Structural and functional insights to Bacillus spore germination and toxin engineering for sustainable agriculture

    Ow Young Villarreal, Giannina Del CarmenUniversity of Cambridge2025

    Bacillus spores exhibit extraordinary resilience, surviving extreme environmental conditions through dormancy and reactivating under favourable conditions via germination. Germination is triggered by specific environmental signals detected by germinant receptors, initiating a cascade of events that …

  5. Characterization of Bacillus Spore Membrane Proteomes and Investigation of Their Roles in the Spore Germination Process

    Chen, YanVirginia Tech2014

    Components of the bacterial spore germination apparatus are crucial for survival and for initiation of infection by some pathogens. While some components of the germination apparatus are well conserved in spore-forming species, such as the spoVA operon, each species may possess a different and …

  6. Identification and Analysis of Germination-Active Proteins in Bacillus Spores

    Sayer, Cameron VincentVirginia Tech2019

    Many spore forming bacteria are the causative agents of severe disease, such as Bacillus anthracis and anthrax. In these cases, the spore often acts as the infectious agent. Spores boast extreme resistance to chemical and UV damage among other bactericidal conditions. This is problematic due to the …
