Phenotypes & Variants

Disruption phenotype

Some early aborted shrunken and deformed seeds, with abnormal hair-like outgrowths, and infertile ovules, and increased salt permeability in seeds associated with an increase in unsubstituted fatty acids but a decrease in omega-hydroxy fatty acids in seed coats.

Variants

We now provide the "Disease & Variants" viewer in its own tab.

The viewer provides 34 variants from UniProt as well as other sources including ClinVar and dbSNP.
