ProSlLYK10:GUS Is Expressed in Arbuscule-Containing Cells of Tomato Roots
(A) GUS activity (magenta) in tomato roots from chimeric plants in the absence of AMF.
(B–C) Transversal (B) and longitudinal (C) sections in a root segment showing GUS staining (E, epidermis; OC, outer cortex; IC, inner cortex; V, vessels).
(D) Tomato ROC line colonized by AMF (GUS staining, blue; AMF staining [WGA-CF488A], green).
(E) Close-up of (C). Arbuscule-containing cells are marked by an asterisk.
Scale bars represent 500 μm in (A) and 50 μm in (B–D).
