This server is constructed around a database dedicated to the analysis of the genome of Escherichia coli: Colibri. Its purpose is to collate and integrate various aspects of the genomic information from E. coli, the paradigm of Gram-negative bacteria. Colibri provides a complete dataset of DNA and protein sequences derived from the paradigm strain E. coli K-12, linked to the relevant annotations and functional assignments. It allows one to easily browse through these data and retrieve information, using various criteria (gene names, location, keywords, etc.). ... [Information of the supplier]
The MIPS Comprehensive Yeast Genome Database (CYGD) aims to present information on the molecular structure and functional network of the entirely sequenced, well-studied model eukaryote, the budding yeast Saccharomyces cerevisiae. In addition the data of various projects on related yeasts are used for comparative analysis. ... [Information of the supplier]
The Index to Plant Chromosome Numbers is an NSF funded project that aims to extract and index original plant chromosome numbers of naturally occurring and cultivated plants published throughout the world. A committee of voluntary contributing editors, located in various parts of the world, reviews sets of serial titles assigned to them and returns the information to the editors for collation in the Index. Chromosome indexes are published every two years. The Index to Plant Chromosome Numbers project has been based at the Missouri Botanical Garden since 1978. Data from published indexes from 1984 onward are available for consultation through this facility. ... [Information of the supplier]
The Integrated Microbial Genomes (IMG) system provides a framework for comparative analysis of the genomes sequenced by the Joint Genome Institute. Its goal is to facilitate the visualization and exploration of genomes from a functional and evolutionary perspective. There are two main approaches to using the system: genes and genomes. Genes can be found by keyword or BLAST query via the Gene Search and then analyzed in the context of their chromosomal, metabolic, and phylogenetic neighborhoods. Genomes of multiple organisms can be selected with the Organism Browser. You can then compare them through the Phylogenetic Profiler in order to identify common or unique properties. ...

This resource gives an overview of the known chromosome numbers, up to now, within the Asteraceae. Through a detailed search mask the chromosome numbers, the taxa investigated, and bibliographic references are accessible. Publications up to and including 2005 are recorded in the resource.

Estimation of nuclear DNA content is the most frequent application of flow cytometry in plants. The growing number of publications in this field calls for an efficient tool to access and analyze the published information. The FLOWer database is a unique resource that lists all publications on DNA flow cytometry and enables their quantitative evaluation. Unbiased data can be obtained on taxonomic groups that were analysed, the use of nuclear isolation buffers and methods of standardization, including DNA reference standards, the use of fluorochromes and measures of result quality. The objective(s) of individual studies can be assessed as well as the flow cytometers that were used, scientific journals in which the results were published and countries of author's origin. ...

In the 21st century, it is becoming increasingly important for students to be aware of and understand basic biotechnological and microbiological concepts. As always, these scientific concepts are most effectively conveyed through hands-on laboratory experiences. However, laboratory exercises are challenging because of the potential risk of student exposure to harmful microbes and chemicals, challenges in maintaining sterility of cultures, cost of scientific materials, and length of time required for preparation and laboratory experiments. Because of the urgent need to improve and expand the biotechnology and microbiology component of curricula using novel, safe, and effective approaches, we have developed this web site. As the centerpiece of this project, we have utilized the halophilic microbe, Halobacterium species NRC-1, which has been extensively studied in our laboratory for the last 20 years, as an ideal teaching vehicle. ...

Aspergillus flavus is a plant, animal, and human pathogen that produces the carcinogen, aflatoxin. An organized multidisciplinary team is coordinating research efforts to control this fungus and to prevent the formation of its toxin in food and feeds. [Information of the supplier]
The rice genome is more than a resource for understanding the biology of a single species. It is a window into the structure and function of genes in other crop grasses as well. Using rice as the sequenced reference genome, researchers can identify and understand the relationships among genes, pathways and phenotypes in a wide range of grass species.Extensive work over the past two decades has shown remarkably consistent conservation of gene order within large segments of linkage groups in rice, maize, sorghum, barley, wheat, rye, sugarcane and other agriculturally important grasses. A substantial body of data supports the notion that the rice genome is substantially colinear at both large and short scales with other crop grasses, opening the possibility of using rice synteny relationships to rapidly isolate and characterize homologues in maize, wheat, barley and sorghum. As an information resource, Gramene's purpose is to provide added value to data sets available within the public sector, which will facilitate researchers' ability to understand the rice genome and leverage the rice genomic sequence for identifying and understanding corresponding genes, pathways and phenotypes in other crop grasses. This is achieved by building automated and curated relationships between rice and other cereals for both sequence and biology. ... [Information of the supplier]
