Abstract excerpt

MicroRNAs (miRNAs) are important for plant development and stress responses. However, factors regulating miRNA metabolism are not completely understood. SICKLE (SIC), a proline-rich protein critical for development and abiotic stress tolerance of Arabidopsis, was identified in this study. Loss-of-function sic-1 mutant plants exhibited a serrated, sickle-like leaf margin, reduced height, delayed flowering, and...
