"Genes controlling SCW formation were activated by the overexpression of LBD30 but not in the LBD30(K226R) mutant. LBD30 enhancement of SCW formation resulted from upregulation of SND1/NST1-mediated transcriptional networks. This study presents a mechanism by which sumoylation of LBD30 mediated by SIZ1 regulates SCW formation in A. thaliana."xsd:string
