Mutations caused by the insertion of members of the Ac or Spm family of transposable
elements result in a great diversity of phenotypes. With the cloning of the mutant genes and …

A major part of the nuclear genome of most plants is composed of different repetitive DNA
elements. Studying these sequence elements is essential for our understanding of the …

This chapter focuses primarily on what is known about the hAT and Enhancer/Suppressor‐
mutator (En/Spm) superfamilies of plant mobile elements. It discusses features of their …

Recent studies have demonstrated that transposable elements in maize and Drosophila are
spliced from pre-mRNA. These transposable element introns represent the first examples of …

We used in vitro mutagenesis and cDNA cloning to identify new Suppressor-mufafor (Spm)
transposable element genes. Frameshift mutations in the ORFs of the tnpA get? & first intron …

Abstract Information about the structure, function and regulation of the maize
Suppressormutator (Spm) transposable element has emerged from the genetic and …

There are six examples of maize transposable elements that are spliced from pre-mRNA.
These represent the first introns that have been added to nuclear genes in recent years. All …

This review focuses on the manipulation of plants by plant breeders that has resulted in a
striking improvement in crop plants, particularly over the last 3 decades. Following an …

Two different factors control the mutability of an unstable allele (c2-m8810581) of the C2
gene of maize. Both an autonomous En/Spm element and an unrelated independent factor …

The Spm's primary transcript is alternatively spliced to give at least 4 different transcripts
which code for proteins with extensive overlapping domains. Two of these proteins, the tnpA …
