In a short-term experiment we studied the effects of increased light and nitrogen (N) availability on the moss Calliergonella cuspidata by cutting vascular plants and adding nitrogen in a calcareous fen in the mountainous region of central Switzerland. Shoots of Calliergonella growing in plots with reduced vascular plant competition showed smaller increments in length of the main axis and produ...

The colonial hydroid Podocoryna carnea grows adherent to surfaces progressing along them by a motile stolon tip. We here ask whether the stolon tip grows preferentially within grooves etched in silicon wafers. In a series of pilot experiments, we varied the dimensions of grooves and found that stolons did not utilize grooves with a width:depth of 5:5 μm or 10:10 μm, occasionally followed groove...

BEL1-like transcription factors are ubiquitous in plants and interact with KNOTTED1 types to regulate numerous developmental processes. In potato (Solanum tuberosum subsp. andigena), the BEL1-like transcription factor StBEL5 and its Knox protein partner regulate tuber formation by targeting genes that control growth. RNA detection methods and heterografting experiments demonstrated that StBEL5 ...
