Abstract
Arabidopsis rfc3 mutants have previously been isolated with an altered fatty acid composition of membrane lipids. In this study, rfc3 was found to have a sucrose-conditional defect in the patterning of distal elements in the lateral root meristem. By utilizing this feature, a sucrose-sensitive process important for lateral root development was localized to the growing portion of rfc3 primary root. Because lateral root formation occurs at a later stage, this finding suggests the existence of an RFC3-dependent, non-primordium autonomous signal playing a role in the organization of lateral root meristem. Map-based cloning of RFC3 gene revealed that it encodes a plastid-localized ribosomal protein S6-like protein and provides a potential link between control of plastid gene expression and LR development.
