Phenotypes & Variants

Disruption phenotype

No obvious defects in morphology (PubMed:15215864).
Plants lacking both XYP1 and XYP2 have morphological defects in vascular development; e.g. discontinuous and thicker veins with the improper interconnection of tracheary elements (TEs) (PubMed:15215864).

Variants

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

The viewer provides 21 variants from UniProt as well as other sources including ClinVar and dbSNP.
