The SKP1-like gene family of Arabidopsis exhibits a high degree of differential gene expression and gene product interaction during development.

The Arabidopsis thaliana genome encodes several families of polypeptides that are known or predicted to participate in the formation of the SCF-class of E3-ubiquitin ligase complexes. One such gene family encodes the Skp1-like class of polypeptide subunits, where 21 genes have been identified and ar...
