Tóm tắt

Summary 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.
