Spotted-leaf mutants form spots in leaves or leaf sheaths under normal condition. The spotted-leaf phenotypes are similar to hypersensitive reaction of plants attacked by pathogen. Identification and characterization of the spotted-leaf mutants are helpful for understanding the mechanisms of resistance to plant diseases.

To understand the genetic and molecular mechanisms of organ growth control, we isolate a set of mutants with altered leaf size and identify the narrow leaf mutant, zhaiye 17 (zy17) (zhaiye means narrow leaf in Chinese). zy17 exhibits narrow leaves, slightly short plants, small panicles, reduced panicle branches and decreased grain numbers per panicle compared with the wild type.
