Lack of ecological context can create the illusion of social success in Dictyostelium discoideum [PDF]
PLoS Comput Biol 12(12): e1005246. 2016, 2016 Studies of cooperation in microbes often focus on one fitness component, with little information about or attention to the ecological context, and this can lead to paradoxical results. The life cycle of the social amoeba Dictyostelium discoideum includes a multicellular stage in which not necessarily clonal amoebae aggregate upon starvation to form a ...

Advanced Science, EarlyView.The salivary sheath protein myosin from SBPH is critical for the formation of the salivary sheath and feeding. However, myosin functions as a HAMP and triggered plant BAK1‐mediated PTI responses, which include the activation of calcium signaling pathways, MAPK phosphorylation, ROS bursts, and cell death, thereby triggering JA pathway.

Assessing Long-Distance Atmospheric Transport of Soilborne Plant Pathogens [PDF]
arXiv, 2023 Pathogenic fungi are a leading cause of crop disease and primarily spread through microscopic, durable spores adapted differentially for both persistence and dispersal. Computational Earth System Models and air pollution models have been used to simulate atmospheric spore transport for aerial-dispersal-adapted (airborne) rust diseases, but the ...

Advanced Science, EarlyView.Day‐night cycles trigger sharp relative humidity (RH) shifts in greenhouses. Rapid humidity drops dehydrate Corynespora cassiicola spores, inducing shrinkage, jerking movements, and weakened inter‐spore connections that drive detachment. Wind is essential for dispersal, with even mild airflow enabling rapid pathogen spread. These synergistic effects of

Real-time In Situ Electron Spin Resonance Measurements on Fungal Spores of Penicillium digitatum during Exposure of Oxygen Plasmas [PDF]
Appl. Phys. Lett. 101, 013704 (2012), 2012 We report the kinetic analysis of free radicals on fungal spores of Penicillium digitatum interacted with atomic oxygen generated plasma electric discharge using real time in situ electron spin resonance (ESR) measurements. We have obtained information that the ESR signal from the spores was observed and preliminarily assignable to semiquinone radical ...

Microbial Biosensor for Sensing and Treatment of Intestinal Inflammation
Advanced Science, EarlyView.The engineered calprotectin biosensor detects gut inflammation, processes the signal through genetic regulation, and responds by expressing the reporter sfGFP and the therapeutic protein secIL10. This dual functionality enables the engineered biosensor not only to sense but also to mitigate gut inflammation, highlighting its potential for disease ...

Detection of Bacterial Endospores in Soil by Terbium Fluorescence
International Journal of Microbiology, 2011 Spore formation is a survival mechanism of microorganisms when facing unfavorable environmental conditions resulting in “dormant” states. We investigated the occurrence of bacterial endospores in soils from various locations including grasslands (pasture,
