Seeds of Arabidopsis plants expressing dominant-negative AtSKD1 under control of the GL2 promoter show a transparent testa phenotype and a mucilage defect.

Abstract excerpt

We have recently shown that overexpression of dominant-negative AtSKD1 versions under control of the trichome and non-root-hair-cell specific GL2 promoter (GL2pro) blocks trafficking of soluble cargo to the vacuole, resulting in its fragmentation and ultimately cell death. GL2pro is also active in the Arabidopsis seeds. When we inspected seeds of the dominant-negative AtSKD1 variants we found two phenotypes. The...
