SAUR1-GUS Promoter Fusion Expression during Rhizobial Infection, and Development of Nodules and Lateral Roots.

A. rhizogenes-induced hairy roots were used to analyze ProSAUR1:GUS expression: (A) to (C) during rhizobial infection; (D) to (F) during nodule development; (G) during the formation of a lateral root primordium; (H) in an emerging lateral root; and (I) in a root tip. The blue color ([A] to [I]) indicates GUS staining of ProSAUR1:GUS activity, and the magenta color (C) indicates LacZ staining of S. meliloti. Bars = 100 μm.
