The researchers then collected pieces of the lit and shady sides of the stem and measured the amount of RNA encoding various proteins and pathways. As they suspected from previous work in other plant ...

Auxin is then directed shootward to the root hair differentiation zone via the transporters AUX1 and PIN2 (step 2, transport).

"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.

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 ...

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.

“By tweaking auxin pathways, scientists might supercharge starch production in crops like rice and maize — essential staples for billions of people,” she said.

With success: Together with his collaborators, he was able to identify five genes that the fungus uses to manipulate the host plant's auxin signaling pathway. These five genes, called Tip1 to Tip5 ...
