Abstract
Compared to other groups of fungi, the knowledge of freshwater predacious fungi that feed on trapped rotifers and tardigrades is very limited. They are known to spread and survive under adverse conditions by releasing asexual spores (conidia), but the environmental factors that induce their conidiation are unclear. In this study, we investigated the conidiation of the rotiferovorous fungus Zoophagus insidians isolated from activated sludge and maintained under laboratory conditions in spring water (medium). We found that its conidiation can undergo significant changes in response to various environmental factors, such as medium exchange, presence or absence of prey, lighting conditions, and their combination. Our results revealed a surprisingly high flexibility of this obligate predacious fungus, which being constantly exposed to unpredictable availability of prey in an unstable environment is still able to survive and disperse.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
