20.500.12556/RUL-138849 No need for speed slow development of fungi in extreme environments Microbial growth under extreme conditions is often slow. This is partly because large amounts of energy are diverted into cellular mechanisms that allow survival under hostile conditions. Because this challenge is universal and diversity in extreme environments is low compared to non-extreme environments, slow-growing microorganisms are not overgrown by other species. In some cases, especially when nutrients are scarce, slow growth was even shown to increase stress tolerance. And in at least some species of extremotolerant and extremophilic fungi, growth rate appears to be coupled with their very unusual morphologies, which in turn may be an adaptation to extreme conditions. However, there is more than one strategy of survival in extreme environments. Fungi that thrive in extremes can be divided into (i) ubiquitous and polyextremotolerant generalists and (ii) rarely isolated specialists with narrow ecological amplitudes. While generalists can compete with mesophilic species, specialists cannot. When adapting to extreme conditions, the risk of an evolutionary trade-off in the form of reduced fitness under mesophilic conditions may limit the maximum stress tolerance achievable by polyextremotolerant generalists. At the same time, specialists are rarely found in mesophilic environments, which allows them to evolve to ever greater extremotolerance, since a reduction of mesophilic fitness is likely to have little impact on their evolutionary success. extreme environments extremotolerance generalist halotolerance slow growth specialist biology ekstremofilne glive ekstremotoleranca hitrost rasti ekstremna okolja true false true Angleški jezik Slovenski jezik Članek v reviji 2022-08-23 11:10:15 2022-08-23 11:10:16 2022-09-15 04:17:17 0000-00-00 00:00:00 2022 0 0 Str. 1-14 Vol. 39 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 579 1749-4613 10.1016/j.fbr.2021.11.002 103798787 1-s2.0-S1749461321000543-main.pdf 1-s2.0-S1749461321000543-main.pdf 1 8695A4CE932076F2568F5F2791D476CD 51a61082043ec5c69b725258767000d789cc0b47774914d0113cfd24f4f9f8c7 fa6cdfd9-22c3-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=159317 https://www.sciencedirect.com/science/article/pii/S1749461321000543 0 620a845d-22c3-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=159316 Biotehniška fakulteta 0 0 0
