I am very excited to share my simultaneous triple staining method for monocot roots. This method is not only faster but also utilizes a smaller volume of stain than traditional methods and minimizes mechanical tissue damage.

Excited to share my latest work in @newphyt.bsky.social. Here, we used TurboID proximity labeling with CLAVATA receptors FEA3 and BAM1D in maize meristems to better understand the signaling pathways important for meristem regulation. #PlantScience

When the fungus Ustilago maydis infects maize plants, tumour-like tissue growths develop. Researchers led by Prof. Armin Djamei have now discovered that the fungus hijacks a programme in the plant that is responsible for forming lateral roots: www.uni-bonn.de/en/news/002-...
