Interpretive Summary:

Technical Abstract: Over 10,000 new mutants have been added to the UniformMu reverse genetics resource in release 7, bringing the total to over 67,000 germinal transposon insertions. These are available in 11,140 independent seed stocks. Close to half of the maize filtered gene set (42%) is represented by at least one Mutator insertion allele, and 65% of these genes have two or more mutant alleles. UniformMu insertion lines can be searched by gene sequence or by GRMZM maize-gene identifiers, and can also be browsed at Seeds can be requested free of charge through this site or directly from the Maize Genetics Cooperation Stock Center. The UniformMu population was created by introgressing a Mutator transposase into a W22 inbred background to provide a uniform phenotypic background for mutant comparisons. Each UniformMu line carries an average of 10 unique, germinal insertions. These lines are provided as segregating F3 material in a “Mu-off”, stable state with a mutable bronze1 allele that serves as a visual marker for activity of the MuDR transposase. Methods and tips for users are available at, including information on how to request seed stocks and effectively test genotype-phenotype cosegregation.
