dc.description.abstractCLAVATA3 (CLV3)/ENDOSPERM SURROUNDING REGION (ESR)-related (CLE) proteins belong to a small peptide family conserved in plants. Recent studies in Arabidopsis and rice have revealed a key role for CLEs in mediating cell-cell communication and stem cell maintenance during plant development, but how CLE signalling controls root development in the rice remains largely unknown. Here it is shown that exogenous application of a synthetic dodeca-amino acid peptide corresponding to the CLE motif of the rice FON2-LIKE CLE PROTEIN2 (FCP2p) protein or overexpression of FCP2 terminates root apical meristem (RAM) activity and impairs late metaxylem formation. FCP2p treatment suppresses the expression of the rice QUIESCENT-CENTER-SPECIFIC HOMEOBOX (QHB) gene, a putative orthologue of Arabidopsis WUSCHEL (WUS)-RELATED HOMEOBOX 5 (WOX5) gene, in both quiescent centre and late metaxylem cells; whereas inducible overexpression of QHB reduces the sensitivity of rice to FCP2p treatment. These results together suggest that in rice RAM maintenance and late metaxylem development are probably controlled by the mutual regulation between FCP2 and QHB. Moreover, a cross-species peptide treatment experiment in Arabidopsis implies that FCP2 has both evolutionarily conserved and species-specific roles in root development.-
