Genome size in Tribolium flour-beetles: inter- and intraspecific variation

  author={Asunci{\'o}n Alvarez-Fuster and Carlos Juan and Eduard Petitpierre},
  journal={Genetics Research},
Eight species of Tribolium and the related species Alphitobius diaperinus have been microdensitometrically analysed by measuring the nuclear content (1C value) of their Feuigenstained spermatids. The range of mean genome sizes goes from 0·157 pg in T. audax to 0·388 pg in T. brevicornis , including five significantly different groups of values. Also, in ail but one species of Tribolium significant intraspecific heterogeneity of genome size was found. The resemblances in genome size are not…

Genome size, chromosomes, and egg-chorion ultrastructure in the evolution of Chrysomelinae

The leaf beetles of the subfamily Chrysomelinae are mostly insects of medium size (5–20 mm. long), frequently shiny and often metallic, variable in shape, but with round and convex outlines

Genome Size and Chromosomal Evolution in Leaf Beetles (Coleoptera, Chrysomelidae)

The rate of chromosomal evolution per genus is not only significantly correlated with species richness but also with the number of host plant families selected by the congeneric species, showing that specialized phytophagy increases the chance of chromosome evolution and speciation, although these two latter aspects are not necessarily linked.

Cytogenetic Analysis of European Cassida (Coleoptera, Chrysomelidae)

The possible trends of the chromosomal evolution in Cassida are discussed in the light of the present subgeneric taxonomy, host-plant selection, and other characteristics.

Satellite DNA of the red flour beetle Tribolium castaneum--comparative study of satellites from the genus Tribolium.

The phylogenetic relationships among Tribolium species deduced from satellite sequence agree with those based on karyological, chemotaxonomic, and hybridization data, indicating a parallel in the divergence of satellites and some genetic and cytogenetic characters.

Variation in nuclear genome size within the Eisenia nordenskioldi complex (Lumbricidae, Annelida)

The aim of this study was to estimate the nuclear genome size in several genetic lineages of the E. nordenskioldi complex using f low cytometry, and found two groups of lineages, with small and large genomes.

C-value estimates for 31 species of ladybird beetles (Coleoptera: Coccinellidae).

No correlation was found between genome size and body size in the ladybirds, in contrast to some other invertebrate groups but in keeping with findings for other beetle families, however, there is some indication that developmental time and/or feeding ecology is related to genome size in this group.

Satellite DNA and heterochromatin of the flour beetle Tribolium confusum.

In situ digestions with restriction enzymes and in situ hybridization show that this satellite DNA is located in pericentromeric positions of all chromosomes coinciding with C-bands, similar to other satellite families from different species of Tenebrionidae.

Reference-Guided De Novo Genome Assembly of the Flour Beetle Tribolium freemani

The T. freemani reference genome and the complete mitogenome presented here represent useful resources for comparative evolutionary studies of related species and for further basic and applied research on different biological aspects of economically important pests.

Rationale to sequence the genome of the red flour beetle , Tribolium castaneum

A molecular recombination map and a physical map based on a BAC library of ~20 x genome coverage are now being completed, and will furnish the necessary foundation upon which to assemble the genomic sequence, which at ~200 Mbs is only slightly larger than that of Drosophila.

Beetling around the genome.

Some of the genetic and genomic tools and biological properties of Tribolium that have established its importance as an organism for agricultural and biomedical research as well as for studies of development and evolution are discussed.

Evolutionary and ecological significance of genome sizes in the copepod genus Pseudocalanus

The six genome sizes among Pseudocalanus, together with those of seven species of Calanus, form a highly significantly nonrandom series of ca.

Genome Size Variation in Diploid Microseris Bigelovii (Asteraceae)

Variation in nuclear 2C DNA content (Feulgen absorbancy) up to 25% was detected among plants from four populations of diploid Microseris bigelovii, adding M. bigelvii to the short list of taxa in which intraspecific variation in DNA content has been detected.

C-banding and DNA content in seven species of Tenebrionidae (Coleoptera)

The relative amount of C-banded heterochromatin varies strikingly in seven species of tenebrionid beetles, from 25 to 58%, but most species show procentric bands only, and the genome sizes agree with the subfamilial taxonomic groupings of these tenesbrionids.

Inter and intraspecific variation in nuclear DNA content in Aedes mosquitoes

Haploid nuclear DNA of 23 species of Aedes, as determined by Feulgen cytophotometry, was found to vary 3-fold. This was accompanied by a 2-fold variation in total chromosomal length. There was a

Nuclear DNA variation in the genus Allium L. (Liliaceae)

A range of 4C DNA values from 41·19 pg to 142·78 pg was found, largely unrelated to basic chromosome number, polyploidy or taxonomic group, but correlated with flowering time, which is discussed in relation to distribution of DNA values in the genus.

A synopsis of the genus Tribolium Macleay, with some remarks on the evolution of its species-groups (Coleoptera, Tenebrionidae).

A very impressive amount of information has now been accumulated concerning the habits and physiology of a few of the species of Tribolium.

Geographic and Ecological Distribution of Genomic DNA Content Variation in Microseris douglasii (Asteraceae)

A correlation between the amount of precipitation and DNA content was temporally observed within a single population near Jolon, California, over a 15-yr interim, and natural selection may be responsible for the observed distributional pattern of DNA content.

Genome size variation in the North American sunfish genus Lepomis (Pisces: Centrarchidae)

The Lepomis data appear to suggest that genome size evolution in these fishes at least follows a continuous rather than a discontinuous mode, and the general predictions of hypothetical models relating genome size variation as a function of organismal position along adaptive continua may be oversimplified, or not applicable to complex, higher eukaryotes.

Nuclear DNA content in the genera Zea and Sorghum. Intergeneric, interspecific and intraspecific variation

Microdensitometry measurements showed that 4C DNA content varied significantly both within the genus Zea as a whole and within maize itself, and no significant differences in DNA content were found between accessions of diploid Sorghum bicolor.
