Article Synopsis
  • Plant-microbe associations are crucial for plant survival and growth, especially in challenging environments, and their dynamics are significantly influenced by factors like soil conditions and plant species.
  • A study was conducted on the microbial communities in the rhizosphere of paper birch, speckled alder, and spruce in a long-undisturbed acidogenic mine tailings deposit, highlighting how vegetation density affects the variety of bacterial and fungal communities.
  • The findings revealed that barren areas with no vegetation had distinct bacterial communities compared to vegetated areas, while fungal communities remained consistent across different vegetation densities, with specific genera showing varied abundance based on plant type.

Mining activities have significant environmental impacts, such as the production of acid mine drainage and the typical absence of vegetation on mine tailings whose absence can facilitate the migration of metals to adjacent ecosystems. We investigated the metal and metalloid composition of plants and substrates on, and near a former gold mine site to understand elemental dynamics in such environments. A mine tailings deposit rich in Mo and As in Northwestern Québec was studied following the natural colonization of the deposit by boreal plant species.

Introns are ubiquitous features of all eukaryotic cells. Introns need to be removed from nascent messenger RNA through the process of splicing to produce functional proteins. Here we show that the physical presence of introns in the genome promotes cell survival under starvation conditions.
