"Auxin signaling pathway controls root hair formation for nitrogen uptake." ScienceDaily. ScienceDaily, 11 September 2023. <www.sciencedaily.com / releases / 2023 / 09 / 230911141134.htm>.

The signaling cascade consists of three stages. Through upregulation of the enzymes TAA1 and YUCCA8, low nitrogen increases auxin accumulation in the root apex (step 1, synthesis).

Finally, NAC1 was linked to the auxin pathway by demonstrating that NAC1 is regulated by auxin, and that the effect of auxin on root formation is mediated by NAC1. NAC1 can even compensate for the ...

"The fungus uses this auxin signaling pathway for its own purposes," explains Prof. Dr. Armin Djamei, who heads the Plant Pathology Department at the INRES Institute of the University of Bonn.

By tweaking auxin pathways, scientists might supercharge starch production in crops like rice and maize—essential staples for billions of people. "There's enormous potential here," Dr. McAdam said.

The gene MADS27, which regulates nitrate absorption, root development and stress tolerance, is activated by the micro-RNA, miR444, therefore offers a way to control these properties of the plant.
