Microspore Wall Morphogenesis and Orbicule Ultrastructure of <i>Isoetes</i>
… layers: perispore, paraexospore, exospore and endospore. Paraexospore formation began during the tetrad stage. The exospore was then formed between the paraexospore and the plasma membrane. During the free spore stage, two walls were formed, the perispore and the endospore. The perispore …

INVESTIGATION OF UNIQUE COENZYME A BIOSYNTHETIC AND REDOX FUNCTIONS IN Bacillus anthracis
… as germination and outgrowth of the B. anthracis endospore, in-frame deletion mutants of their respective encoding genes, cdr and cdrX, were constructed, singly and in combination. Both BACoADR and CoADR-RHD appear to have a role in the morphological transition from the endospore to the vegetative …

Screening For Cry Genes From Bacillus Thuringiensis In Various Textural Classes Of Southwest Missouri Soils
Bacillus thuringiensis is a gram-positive endospore-forming bacterium that produces an insecticidal δ-endotoxin during sporulation. The δ-endotoxin consists of an inactive protein toxin crystal (protoxin) that becomes activated by the alkaline conditions in the intestinal lumen of specific insect …

Characterization of the Components of Carbon Catabolite Repression in Clostridium perfringens
… of C. perfringens is its ability to form an endospore. The symptoms of C. perfringens food poisoning are directly correlated to the release of an enterotoxin at the end of the sporulation process. The sporulation process in C. perfringens is subject to carbon catabolite repression (CCR) by …
