Spores are the major transmissive form of the nosocomial pathogen Clostridium difficile, a leading cause of healthcare-associated diarrhea worldwide. Successful transmission of C. difficile requires that its hardy, resistant spores germinate into vegetative cells in the gastrointestinal tract. A critical step during this process is the degradation of the spore cortex, a thick layer of peptidogl...
Pectin methylesterase (PME) controls the methylesterification status of pectins and thereby determines the biophysical properties of plant cell walls, which are important for tissue growth and weakening processes. We demonstrate here that tissue-specific and spatiotemporal alterations in cell wall pectin methylesterification occur during the germination of garden cress (Lepidium sativum). These...
Bacterial endospore dormancy and resistance properties depend on the relative dehydration of the spore core, which is maintained by the spore membrane and its surrounding cortex peptidoglycan wall. During spore germination, the cortex peptidoglycan is rapidly hydrolyzed by lytic enzymes packaged into the dormant spore. The peptidoglycan structures in both dormant and germinating Bacillus anthra...
Terrestrial plant pollen is classified into two categories based on its metabolic status: pollen with low-metabolism are termed "orthodox" and pollen with high-metabolism are termed "recalcitrant." Nicotinamide adenine dinucleotide (NAD) is crucial for a number of metabolisms in all extant organisms. It has recently been shown that NAD homeostasis plays an important role in a broad range of dev...
Appearance of an Alternate Pathway Cyanide-resistant during Germination of Seeds of Cicer arietinum.
The combined action of the inhibitors antimycin A and cyanide with benzohydroxamic acid indicates the presence of a cyanide-resistant pathway of respiration in chick pea (Cicer arietinum L.) seeds. The appearance of this pathway takes place during germination. During the first 12 hours of germination, the respiration is predominantly cyanide-sensitive, showing after this time a shift to an "alt...
