Plant Transposable Elements
TL;DR: DNA sequence analyses have shown that transposable elements may share certain structural features that might be useful for classification, and transposition can now be demonstrated by DNA hybridization techniques that were unknown 20 years ago.
Journal ArticleDOI
Molecular cloning of the a1 locus of Zea mays using the transposable elements En and Mu1
Catherine O’Reilly,Nancy S. Shepherd,Andy Pereira,Zsuzsanna Schwarz-Sommer,Isolde Bertram,Donald S. Robertson,Peter A. Peterson,Heinz Saedler +7 more
TL;DR: By a process of cross‐screening of the positives from the two libraries and by molecular analysis of the En‐positive clones it was possible to identify clones in both libraries carrying all or part of the a1 gene.
Journal ArticleDOI
Influence of transposable elements on the structure and function of the A1 gene of Zea mays.
Zsuzsanna Schwarz-Sommer,Nancy S. Shepherd,Eckhard Tacke,Alfons Gierl,Wolfgang Rohde,Lise Leclercq,Maryann G. Mattes,Rita Berndtgen,Peter A. Peterson,Heinz Saedler +9 more
TL;DR: Sequence analysis of revertant alleles of the mutable a1‐ml allele with either recessive or wild‐type phenotype indicates that frame‐shift mutations abolish A1 gene function, whereas one additional amino acid within the protein sequence still allows wild‐ type gene expression.
Journal ArticleDOI
Similarity of the Cin1 repetitive family of Zea mays to eukaryotic transposable elements
Nancy S. Shepherd,Zsuzsanna Schwarz-Sommer,Jutta Blumberg vel Spalve,Manju Gupta,Udo Wienand,Heinz Saedler +5 more
TL;DR: DNA nucleotide sequence data show that some members of the Cin1 middle repetitive family of maize have features characteristic of known transposable elements, including a 6-base pair perfect inverted repeat sequence at its ends.
Journal ArticleDOI
A general method to identify plant structural genes among genomic DNA clones using transposable element induced mutations
Udo Wienand,Hans Sommer,Zs. Schwarz,Nancy S. Shepherd,Heinz Saedler,Fritz Kreuzaler,Hermann Ragg,E. Fautz,Klaus Hahlbrock,Brian J. Harrison,Peter A. Peterson +10 more
TL;DR: Among the 5 different clones from Petroselinum hortense, PH3 is the most likely candidate to contain at least a portion of the chalcone synthase gene, which is altered in the mutant nivea recurrens (nivrec), this mutant is considered to be due to the integration of a transposition element.
