While many bacteria become inactive during dry spells, specific groups persist and even thrive. A new study, published in Nature Communications and conducted by the Center for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna, offers ground-breaking insights into bacterial activity during drought periods, with implications for agriculture and our understanding of climate change impacts.
. Growing bacteria incorporated the oxygen from the water vapor into their DNA, allowing for a measure of growth without adding liquid water to the soil.
during drought was influenced by whether the soils had been exposed to current or future climatic conditions, i.e., higher temperatures and COIn the heart of Styria, the"ClimGrass" experiment paints a vivid picture of the future. Here, 54 experimental plots simulate the world of tomorrow. Infrared heaters elevate temperatures to levels expected in future climate scenarios, while miniFACE systems adjust atmospheric COconcentrations.
The filamentous growth of this bacterium might allow it to bridge disconnected pore spaces in drought-stricken soils, enabling it to access water and nutrients from distant sources. Previous studies have indicated that such bacteria might play a role in aiding plants to cope with drought.
