GRAS proteins form a DNA binding complex to induce gene expression during nodulation signaling in Medicago truncatula.

The Plant cell - 1 Feb 2009

Hirsch Sibylle, Kim Jiyoung, Muñoz Alfonso, Heckmann Anne B, Downie J Allan, Oldroyd Giles E D

Abstract excerpt

The symbiotic association of legumes with rhizobia involves bacterially derived Nod factor, which is sufficient to activate the formation of nodules on the roots of the host plant. Perception of Nod factor by root hair cells induces calcium oscillations that are a component of the Nod factor sign...
