DEDICATION
There are few instances in science in which the genesis of a field of
research is identified as closely with one person as is that of transposable
elements and Barbara McClintock. Our meeting was still another tribute to
her brilliant analyses of mosaic kernel phenotypes that arose initially in
the progeny of plants subjected to systematic genome disruption.
The last few years have witnessed continuous advances in our under
standing of the structure of these elements and their effects on gene func
tion as the techniques of molecular biology have been brought to bear, and
it is these recent advances that were highlighted here against a back
ground of the taxonomy and formal genetics of the transposable elements.
The Scientific Organizing Committee hoped in this manner to present a co
herent and integrated view of transposable elements that would open the
area to those not already intimately familiar with the subject, while
simultaneously permitting substantive interchanges among researchers in
the field.
The suggestion that we organize this symposium to explore advances
in our knowledge of plant transposable elements came from Alexander
Hollaender of the Council for Research Planning in Biological Sciences. He
participated in our initial planning as a member of the Scientific Organizing
Committee, but he was not to see those plans brought to fruition.
Alexander Hollaender died in December, 1986 after an illustrious career in
research and administration. Claire Wilson, his associate at the Council
for Research Planning, assisted in plans for this symposium and prepared,
with the help of Cosette Saslaw, the manuscripts presented here for publi
cation.
We have dedicated this symposium to Barbara McClintock, whose re
search opened new horizons in our knowledge of genome organization, and
to the memory of Alexander Hollaender.

SUPPRESSOR-MUTATOR ELEMENT

INTRODUCTION
The Suppressor-mutator (Spm) element is one of the most extensively
studied maize transposable elements. It is the fully functional member of a
transposable element family containing many functionally altered and mutant
members. McClintock's genetic studies on the Spm family defined the
functional interrelationships both among elements of the family and between
the elements and genes with Spm insertion mutations (12-27). Rhoades
and Dempsey (35) independently identified mutations caused by the same
element family; these were subsequently studied by Peterson (30-34), who
named the element Enhancer (En).
Many elements of the Spm family have recently been cloned and ana
lyzed, as have several genes with Spm insertion mutations (1,8,10,28,29,
38,39,41). The Spm and En elements are very similar 8.3-kb elements:
the two that have been sequenced differ in length by four nucleotides,
and in sequence by an additional six nucleotides (11,28). None of the
differences appears to affect element function. Many mutant elements have
also been analyzed. The predominant class of mutant element comprises
transposition-defective, internally deleted Spm elements (dSpm). There
exist several additional types of Spm element designated Spm-weak
(Spm-~), inactive Spm (Spm-.!), and MOdlIier (Mod). -- ---
There are two types of mutant alleles with dSpm insertions in which
expression of the gene has come under the control of the inserted element.
These have been designated Spm-suppressible and Spm-dependent (11).
In an Spm-suppressible allele, the gene with the dSpm insertion continues
to be expressed in the absence, but not in the presence, of a trans-acting
Spm. By contrast, an Spm-dependent allele is expressed only in the pres
ence of a functional Spm element elsewhere in the genome. We have inter
preted such interactions between genes and Spm elements as a reflection of
the element's regulatory system (11). --
