Abstract

SummaryWe have used a universal adaptor amplification procedure to isolate random Mutator‐tagged fragments from Mutator‐active maize plants. Direct sequence characterization of 761 Mutator‐tagged fragments indicated that a significant number were homologous to sequences within the public databases. The ability of Mutator‐tagged fragments to detect homology was not related to the length of the sequence within the range 100–400 bp. However, fragments above this size did show an increased chance of detecting homology to either expressed sequence tags or genes. Characterization of the insertion sites of the Mutator elements suggested that while it does target transcribed regions, Mutator does not appear to have any site preference within the transcription unit. Hybridization of previously unidentified Mutator‐tagged fragments to arrayed cDNA libraries confirmed that many of these also showed homology to transcribed regions of the genome. Examination of back‐crossed progeny confirmed that all the insertions examined were germinal; however, in all but one case, selfing five individual Mutator‐tagged lines failed to reveal an obvious phenotype. This study suggests that the random sequencing of Mutator‐tagged fragments is capable of producing both a significant number of interesting transposon tagged genes and mutant plant lines, all of which could be extremely valuable in future gene discovery and functional genomics programmes.
