Germplasm Phenotype:

• CS69972  — Reduced abscisic acid (ABA) sensitivity during seed germination. Strongly increased ABA sensitivity of root growth.
• CS800068  — Slightly longer primary root, less columella stem cell differentiation, equally sensitive to N-1-naphthylphthalamic acid (NPA) treatment as Col-0.
• pp2a-3/pp2a-4  — Short primary root, further reduced columella differentiation, and severely disrupted cell organization in the root tip compared with wild type; not significantly more sensitive to cantharidin than Col-0.
