LONG-TERM EXPERIMENTAL EVOLUTION REVEALS PURIFYING SELECTION ON PIRNA-MEDIATED CONTROL OF TRANSPOSABLE ELEMENT EXPRESSION

Long-term experimental evolution reveals purifying selection on piRNA-mediated control of transposable element expression

Abstract Background Transposable elements (TEs) are an almost universal constituent of eukaryotic genomes.In animals, Piwi-interacting small RNAs (piRNAs) and repressive chromatin often play crucial roles in preventing TE transcription and thus restricting TE activity.Nevertheless, TE content varies widely across eukaryotes and the dynamics of TE a

Design and evaluation of a multi-level reactive power market

Abstract The shift from conventional power plants on transmission level to distributed energy resources in the distribution grids requires procedures to enable efficient and economic reactive power exchange across different voltage levels.In this paper, we propose a multi-level reactive power market that enables reactive power provision from distri

CONTROLLING THE PESTS WITH THE HELP OF PLANTS IN ORGANIC VINEYARDS

The capability of plants of increasing the ecosystem resistance to pests and invasive species is a well-known ecosystem service.However, monocultures (including vineyards) do not exploit the potential of plant diversity.The aims of this research are to develop new viticultural systems based on increased plant diversity within (e.g., cover crops) an
