Constitutive Expression of PAT10 by Pro_PAT10:GUS Reporter Analysis.

(A) A mature embryo freshly dissected from rehydrated mature seeds.

(B) A cotyledon showing GUS signals at vascular tissues.

(C) A true leaf showing strong GUS signals at hydathodes, trichomes, and guard cells.

(D) A seedling at 15 DAG showing constitutive GUS signals at both aerial parts and in roots.

(E) A lateral root.

(F) A transverse section of Pro_PAT10:GUS transgenic roots showing strong GUS signal at the phloem but not at the xylem.

(G) A longitudinal section of Pro_PAT10:GUS transgenic roots showing strong GUS signal at the vascular bundles.

(H) An open flower of a Pro_PAT10:GUS transgenic plant showing strong GUS signal at the style and stomata of floral organs.
