narrow albino leaf 1 (naal1), was obtained from a rice mutant population generated from an EMS-induced indica variety Shuhui527 (SH527), and is mainly characterized by reduced plant height, narrow and albino leaves, a reduced number of crown roots, and an increased number of trichomes. Map-based cloning and genetic complementation experiments indicate that NAAL1, which encodes a CHR4/MI-2-like protein, is allelic with CHR729/OsCHR4, a gene known to regulate the methylation of H3K4 and H3K27. NAAL1 was expressed in a constitutive form in the rice root, stem, leaf sheath, and panicle. Further functional studies showed that NAAL1 had a combined effect with a plurality of genes that work within a network regulating leaf shape Moreover, this gene was involved in the synthesis, transport, and signaling of auxin, and thereby affecting the development of the root system, leaf vascular bundles, leaf morphogenesis, as well as the development of panicle traits." />
