| Comments |
Protein family of 21 members-Root but not seed suberin phenotype. Other family members may have redundant functions. Double mutant of kcs2kcs20 results in 15-20% reduction in cuticular wax. STKCS6 homology to both AtKCS6 and AtKCS5 is similar; it cannot unambiguously be assumed that StKCS6 is the potato orthologue of AtKCS6.
