Analysis of repetitive DNA distribution patterns in the Tribolium castaneumgenome (2008)

Wang, Suzhi, Lorenzen, Marcé D, Beeman, Richard W, Brown, Susan J

Abstract Background Insect genomes vary widely in size, a large fraction of which is often devoted to repetitive DNA. Re-association kinetics indicate that up to 42% of the genome of the red flour...

Multiple alleles at the black locus in Tribolium castaneum (1985)

Beeman, Richard W., Nanis, Suzanne M.

Two alleles at the black locus in the red flour beetle Tribolium castaneum (Herbst) have been resolved. Dusky (bd), the lighter-colored of the two, is dominant to tawny (bt), the darker. Both are...

Linkage analysis of genes affecting scale color, eye color, and resistance to malathion in he Indianmeal moth (1983)

Beeman, Richard W.

Golden (g), a spontaneous mutation affecting scale color in the Indianmeal moth, Plodia interpunctelia (Hubner), is described. The golden gene is a simple Mendelian autosomal recessive. In affected...

Laccase 2 is the phenoloxidase gene required for beetle cuticle tanning

Arakane, Yasuyuki, Muthukrishnan, Subbaratnam, Beeman, Richard W., Kanost, Michael R., Kramer, Karl J.

Cuticle tanning (or sclerotization and pigmentation) in invertebrates involves the oxidative conjugation of proteins, which renders them insoluble and hardens and darkens the color of the...

Genetic Linkage Maps of the Red Flour Beetle, Tribolium castaneum, Based on Bacterial Artificial Chromosomes and Expressed Sequence Tags

Lorenzen, Marcé D., Doyungan, Zaldy, Savard, Joel, Snow, Kathy, Crumly, Lindsey R., Shippy, Teresa D., ...

A genetic linkage map was constructed in a backcross family of the red flour beetle, Tribolium castaneum, based largely on sequences from bacterial artificial chromosome (BAC) ends and untranslated...

Cloning and characterization of the Tribolium castaneum eye-color genes encoding tryptophan oxygenase and kynurenine 3-monooxygenase.

Lorenzen, Marcé D, Brown, Susan J, Denell, Robin E, Beeman, Richard W

The use of eye-color mutants and their corresponding genes as scorable marker systems has facilitated the development of transformation technology in Drosophila and other insects. In the red flour...

The Tribolium castaneum Ortholog of Sex combs reduced Controls Dorsal Ridge Development

Shippy, Teresa D., Rogers, Carmelle D., Beeman, Richard W., Brown, Susan J., Denell, Robin E.

In insects, the boundary between the embryonic head and thorax is formed by the dorsal ridge, a fused structure composed of portions of the maxillary and labial segments. However, the mechanisms that...

Analysis of the Tribolium homeotic complex: insights into mechanisms constraining insect Hox clusters

Shippy, Teresa D., Ronshaugen, Matthew, Cande, Jessica, He, JianPing, Beeman, Richard W., Levine, Michael, ...

The remarkable conservation of Hox clusters is an accepted but little understood principle of biology. Some organizational constraints have been identified for vertebrate Hox clusters, but most of...

Analysis of repetitive DNA distribution patterns in the Tribolium castaneum genome

Wang, Suzhi, Lorenzen, Marcé D, Beeman, Richard W, Brown, Susan J

Approximately 30% of the Tribolium castaneum genome is comprised of repetitive DNA. These repeats accumulate in certain regions in the assembled T. castaneum genome, these regions might be derived...
