Antifungal and other bioactive properties of the volatilome of Streptomyces scabiei | Applied and Environmental Microbiology This study reveals that Streptomyces scabiei, the bacterium causing common scab in root and tuber crops, produces a wide variety of volatile chemicals with surprising benefits. These natural compounds can inhibit the growth of other harmful microbes, including fungal plant pathogens. Some of these chemicals are already known to fight pests and diseases, while others, like 3-penten-2-one, are newly discovered as potential antifungals. Even more unexpectedly, some of the identified compounds may help plants grow or boost their defenses. Combined with previous work, our findings challenge the idea that S. scabiei is purely harmful and suggest it might, under certain conditions, stimulate plant defense and can act protectively in its environment.

The impact of land-use changes and management intensification on bacterial communities in the last decade: a review | Applied and Environmental Microbiology The land-use change in the last 10 years resulted in the conversion of native vegetation into annual or perennial crop systems (1). Land-use change has a pronounced impact on the soil physical and chemical characteristics, modifying the diversity and functioning of microbial communities (2, 3). The effect on the structure and diversity of bacteria in the soil is very variable. Forest clearing decreases the abundance of bacterial phyla (4), while in agricultural systems greater diversity can be found than in natural forests (2).
