Untitled Document Although it is generally agreed that the vast majority of this genome size variation can be ascribed to differences in the repetitive fraction of the genome, the relative importance of mechanisms that generate genome size variation is not well understood. Therefore, it is of interest to determine the identity of the non-genic DNA that contribute to genome size variation, the mechanisms by which this variation arises, and their relevance to organismal fitness and evolution. By sequencing approximately 0.14% of the haploid genome for each of the four species, we hope to gain insight into the spectrum and frequency of the types of repetitive sequences present, and their relative contribution to genome size variation in Gossypium. www.eeob.iastate.edu /faculty/WendelJ/genomeevolution.htm   (352 words)

GENOME SIZE, DEVELOPMENTAL RATE, AND BODY SIZE IN FRESHWATER CYCLOPOID COPEPODS   (Site not responding. Last check: 2007-10-08) Species with genome sizes ranging from 0.8 - 4.1 pg DNA were reared in the laboratory under defined conditions at 15, 22 and 30 C in order to examine growth parameters under the range encountered in nature. Chromatin diminution, the excision of large proportions of the presomatic genome during embryogenesis in some copepods, is proposed as one mechanism that regulates genome size, and hence contributes to the life history variations observed in nature. Three explanations of the variation in genome size and related life history traits are discussed: 1) prevalence of chromatin diminution, 2) phylogenetic structure, and 3) nucleotypic selection that may influence life history variation and fitness. aslo.org /santafe99/abstracts/SS24TH0400H.html   (230 words)

Phycologia: Relationship of nuclear genome size to some reproductive cell parameters in the Florideophycidae ...   (Site not responding. Last check: 2007-10-08) Three related trends were identified: (1) genome size is positively correlated with carpospore volume; (2) species with larger genomes produce fewer carpospores per cystocarp; and (3) species that produce larger carpospores produce fewer carpospores per cystocarp. The diversity in genome sizes of organisms with similar life histories probably represents a balance between r- and K-selection and between the selective forces on the genotype and phenotype (Cavalier-Smith 1985a; Begon et al. Specifically, the investigation was designed to provide quantitative information on carpospore size and the number of carpospores produced per cystocarp for representative red algal species, and to compare these data with estimates for their nuclear genome sizes. www.findarticles.com /p/articles/mi_qa3850/is_200209/ai_n9114470   (1390 words)

Biotech Adventures - Oklahoma State University -- Genetics Section --   (Site not responding. Last check: 2007-10-08) The genome refers to a collection of all of the genes found on all of the chromosomes in the nucleus of an organism. The size of the genome (the amount of DNA material) is generally indicates the complExity of the organism. For example, the genome of a human is almost 25 times larger than the plant, but it appears that humans have only about 1000 more actual genes than does a plant. biotech-adventure.okstate.edu /low/basics/genetics/genomes   (170 words)

Genome size and longevity in fish.   (Site not responding. Last check: 2007-10-08) The wide variety of genome sizes (measured as C-value) observed across taxa is not related to organismal complexity or number of coding genes. In order to determine whether genome size is a general predictor of longevity, we have extended the analysis to the Actinoptergyian fish, a widely divergent group in terms of both longevity and genome size. Analysis of covariance using order as a cofactor shows a significant effect of genome size on longevity (corrected for body mass), with lifespan increasing as a function of genome size. www.arclab.org /medlineupdates/abstract_12581799.html   (201 words)

UCPE-Research-Theme 6-Genome size This was followed by the demonstration of a close correlation between leaf phenology and genome size (150) and, more recently, nuclear DNA content has been correlated with frost sensitivity (417). With increasing interest in climate change, the scene is set for genome size to emerge as a strong candidate for further intensive study to justify its inclusion in models predicting future vegetation responses. Analysis is now in progress to test predictions of differential responses to these manipulations by co-existing plant species of contrasted genome size. www.shef.ac.uk /~nuocpe/ucpe/theme6.html   (294 words)

PAG-IX: GENOME SIZE OF THE GENUS Fragaria   (Site not responding. Last check: 2007-10-08) Genome size is essential information for genome research and the studies of diversity and evolution of plants. Therefore, the DNA contents in many plant species have been measured and the data have been accumulated. The genome size of Fragaria vesca (diploid species) was determined as 170 Mbp/C and that of Fragaria ananassa (Octaploid species) ranged from 578 to 605 Mbp/C. Fragaria species have small genome sizes as revealed in this study. www.intl-pag.org /9/abstracts/P04_01.html   (229 words)
