<jats:p>
Eight novel families of miniature inverted repeat transposable
elements (MITEs) were discovered in the African malaria mosquito,
<jats:italic>Anopheles gambiae</jats:italic>
, by using new software designed to
rapidly identify MITE-like sequences based on their structural
characteristics. Divergent subfamilies have been found in two families.
Past mobility was demonstrated by evidence of MITE insertions that
resulted in the duplication of specific TA, TAA, or 8-bp targets. Some
of these MITEs share the same target duplications and similar terminal
sequences with MITEs and other DNA transposons in human and other
organisms. MITEs in
<jats:italic>A. gambiae</jats:italic>
range from 40 to 1340
copies per genome, much less abundant than MITEs in the yellow fever
mosquito,
<jats:italic>Aedes aegypti</jats:italic>
. Statistical analyses suggest
that most
<jats:italic>A. gambiae</jats:italic>
MITEs are in highly AT-rich
regions, many of which are closely associated with each other. The
analyses of these novel MITEs underscored interesting questions
regarding their diversity, origin, evolution, and relationships to the
host genomes. The discovery of diverse families of MITEs in
<jats:italic>A.
gambiae</jats:italic>
has important practical implications in light of
current efforts to control malaria by replacing vector mosquitoes with
genetically modified refractory mosquitoes. Finally, the systematic
approach to rapidly identify novel MITEs should have broad applications
for the analysis of the ever-growing sequence databases of a wide range
of organisms.
