• The shoot organization2 (sho2) mutant, a weak allele of SHOOTLESS4 that is a ZIPPY/ARGONAUTE7 homolog in rice, shows a variety of leaf abnormalities; filamentous leaves, bi- or trifurcated leaves, separation of the filamentous structure from the leaf blade or deletion of the margin
• The expression pattern of SHO2 in the outer layer of the shoot apical meristem and the adaxial surface of the leaf, as well as the altered expression of HD-ZIP III and ETTIN homologs in the central domain of sho2 leaves, suggest that normal development of the central domain is a prerequisite for the synchronous growth of the three domains
• The mechanism regulating the pattern of leaf initiation was analyzed by using shoot organization (sho) mutants derived from three loci (SHO1, SHO2, and SHO3)
• Rice SHL2, SHL4/SHO2, and SHO1 encoded orthologues of Arabidopsis RNA-dependent RNA polymerase 6, ARGONAUTE (AGO) 7, and DICER-like 4, respectively, whose mutations affect leaf development through the trans-acting siRNA (ta-siRNA) pathway
• The gain-of-function experiment by the ectopic expression of SHL4 resulted in reduced accumulation of an microRNA, miR166, and partial adaxialization of leaves, supporting a role for the ta-siRNA pathway in the maintenance of leaf polarity as previously reported in maize
• The leaf founder cells for the lateral and marginal domains are recruited normally in sho2, indicating that sho2 is defective in the growth of leaf domains after the founder cells are recruited
• Mutations in rice SHOOTLESS2 (SHL2), SHL4/SHOOT ORGANIZATION2 (SHO2), and SHO1 cause complete deletion or abnormal formation of the SAM
• According to high-sequence conservation, the rolled-leaf gene in rice could be orthologous to the Arabidopsis ZIP/Ago7 gene, so we called it OsAGO7
• Over-expression of rice OsAGO7 gene induces upward curling of the leaf blade that enhanced erect-leaf habit

• OsAGO7~shl4~SHO2, RL9~SLL1, Isolation and characterization of a rice mutant with narrow and rolled leaves, NAL7 and SLL1 were found to be upregulated, whereas OsAGO7 were downregulated in the nrl1 mutant
