Intron Size and Genome Size in Plants [PDF]
It has long been known that genomes vary over a remarkable range of sizes in both plants (Bennett, Cox, and Leitch 1997) and animals (Gregory 2001). It also has become evident that across the broad phylogenetic sweep, genome size may be correlated with intron size (Deutsch and Long 1999; Vinogradov 1999; McLysaght et al.

Spiders represent a diverse and familiar group of animals, but to date no information has been made available regarding their genome sizes. Arachnids in general have been almost entirely overlooked, and are currently represented by a single tick in the animal genome size data set.

A Model for Genome Size Evolution [PDF]
We present a model for genome size evolution that takes into account both local mutations such as small insertions and small deletions, and large chromosomal rearrangements such as duplications and large deletions. We introduce the possibility of undergoing several mutations within one generation.

Genome size evolution in the Archaea [PDF]
What determines variation in genome size, gene content and genetic diversity at the broadest scales across the tree of life? Much of the existing work contrasts eukaryotes with prokaryotes, the latter represented mainly by Bacteria. But any general theory of genome evolution must also account for the Archaea, a diverse and ecologically important group ...

Is There an Upper Limit to Genome Size? [PDF]
At 50-fold the size of the human genome (3 Gb), the staggeringly huge genome of 147.3 Gb recently discovered in the fern Tmesipteris obliqua is comparable in size to those of the other plant and animal record-holders (i.e., Paris japonica, a flowering plant with a genome size of 148.8 Gb, and Protopterus aethiopicus, a lungfish with a genome of 130 Gb).

The evolution of genome size in ants [PDF]
Despite the economic and ecological importance of ants, genomic tools for this family (Formicidae) remain woefully scarce. Knowledge of genome size, for example, is a useful and necessary prerequisite for the development of many genomic resources, yet it has been reported for only one ant species (Solenopsis invicta), and the two published estimates ...

Eukaryotic genome size databases [PDF]
Three independent databases of eukaryotic genome size information have been launched or re-released in updated form since 2005: the Plant DNA C-values Database (www.kew.org/genomesize/homepage. html), the Animal Genome Size Database (www. genomesize.com) and the Fungal Genome Size Database (www.zbi.ee/fungal-genomesize/).

Genome Size and Species Diversification [PDF]
Theoretically, there are reasons to believe that large genome size should favour speciation. Several major factors contributing to genome size, such as duplications and transposable element activity have been proposed to facilitate the formation of new species. However, it is also possible that small genome size promotes speciation.

The laws of natural selection dictate that bacteria will eventually develop resistance to practically any antibiotic. Selective pressure exerted by widespread antimicrobial use is a driving force in the development of antibiotic resistance. —Stuart Levy The quotation above (http://www.tufts.edu/med/apua/Practitioners/ABRcontrol.html) has led to ...

Genome size and genomic
• Lentibulariaceae contains species with the smallest genome size in tracheophytes, yet data are available only for 8% of its species. This prevents understanding of the history of miniaturization events and their possible reasons. Nothing is known about the variation of genomic DNA base composition.
