Fern spore viability considered in relation to the duration of the Cretaceous-Paleogene (K-Pg) impact winter. A contribution to the discussion

Acta Palaeobotanica, 2019
The Cretaceous-Paleogene (K-Pg) boundary Chicxulub impact is supposed to have produced a nearly decade-long impact winter which resulted in a mass-extinction event among dicot angiosperms but which left pteridophytes comparatively unaffected.

Aspergillus niger Spores Are Highly Resistant to Space Radiation [PDF]

, 2020
The filamentous fungus Aspergillus niger is one of the main contaminants of the International Space Station (ISS). It forms highly pigmented, airborne spores that have thick cell walls and low metabolic activity, enabling them to withstand harsh ...

Site-specific factors influencing Hymenoscyphus fraxineus spore dispersal: the role of understorey vegetation and slope steepness in ash dieback spread

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
Ash dieback (ADB), caused by Hymenoscyphus fraxineus, is a severe threat to Fraxinus excelsior populations across Europe, with spore dispersal playing a critical role in disease progression. While broad-scale environmental drivers of spore dispersal are

UV Disinfection sensitivity index of spores or protozoa: A model to predict the required fluence of spores or protozoa

Water Science and Technology, 2022
During UV disinfection, the required UV dose in terms of fluence depends upon the species of bacteria spore and protozoa. To rank their UV disinfection sensitivity, spore sensitivity index (SPSI) and protozoan sensitivity index (PSI) are defined.

Identification of Differentially Expressed Genes during Bacillus subtilis Spore Outgrowth in High-Salinity Environments Using RNA Sequencing

Frontiers in Microbiology, 2016
In its natural habitat, the soil bacterium Bacillus subtilis often has to cope with fluctuating osmolality and nutrient availability. Upon nutrient depletion it can form dormant spores, which can revive to form vegetative cells when nutrients become ...

Asexual and sexual replication in sporulating organisms

, 2006
This paper develops models describing asexual and sexual replication in sporulating organisms. Replication via sporulation is the replication strategy for all multicellular life, and may even be observed in unicellular life (such as with budding yeast ...

The proppin Bcas3 and its interactor KinkyA localize to the early phagophore and regulate autophagy [PDF]

, 2021
To resolve the signaling mechanisms that mediate the starvation-induced processes of Dictyostelium sporulation and encystation, we performed insertional mutagenesis on cells harboring an mRFP-tagged spore gene.

Influences of Lactate on the High-density Fermentation by Bacillus licheniformis HK

Shipin gongye ke-ji
To improve the biomass and spore rate of Bacillus licheniformis HK, influences of lactate on cell growth and metabolism and spore production were investigated at a 20 L bioreactor, and lactate addition was conducted by coupling with pH7.0 from 16 h to 32
