OsSPL88 Encodes a Cullin Protein that Regulates Rice Growth and Development

Plant lesion mimics refer to necrotic spots spontaneously produced by the plant without mechanical damage, pathogen invasion, and adversity stress. Here, we isolated and characterized two rice ( L) mutants, namely, ( - ) and ( - ), which were identified from an ethyl methanesulfonate-mutagenized cul...

Summary:Plant lesion mimics refer to necrotic spots spontaneously produced by the plant without mechanical damage, pathogen invasion, and adversity stress. Here, we isolated and characterized two rice ( L) mutants, namely, ( - ) and ( - ), which were identified from an ethyl methanesulfonate-mutagenized cultivar Xiushui 11 population. Physiological and biochemical experiments indicated that more ROS accumulated in and than in wild type. and displayed spontaneous cell death and enhanced their resistance to bacterial blight by affecting the expression of defense-related genes. We isolated by map-based cloning, which encoded a highly conserved Cullin protein. A single base deletion was detected in and , in which the 132nd base C of and the 381th base T of were deleted, causing premature termination of protein translation. was expressed in root, stem, leaf, leaf sheath, and panicle. The Cullin protein was localized in the cytoplasm and nucleus. The aforementioned results indicate that regulates the growth and development of rice by affecting the expression of defense-related genes.
