There are several www-sites devoted to Gesneriaceae (see Links to other Gesneriaceae websites). However, their focus is usually on plants used as ornamentals or at least on species that are in cultivation. In contrast, many genera of Gesneriaceae received little attention and are largely unknown to a broader public. The present webpage attempts to fill the gap by providing a survey of all genera of the family. The number of genera is between 140 and 150 depending on the generic concepts used by taxonomists. We also present an overview of the family, and we include classifications of various authors so that readers will see the generic relationships. ... [Information of the supplier]
The Gentian Research Network is a free, not-for-profit, web-based forum for worldwide research on the natural history and evolution of the flowering plant family Gentianaceae (gentians). Here you will find information on current research projects in the Gentianaceae, focusing on their systematics, evolution, molecular systematics, classification (Struwe et al. 2002 or most current), ecology, biogeography, endangered species, biodiversity, distribution, anatomy, morphology, palynology, ethnobotany, and nomenclature. We also have a link to a large reference list, floristic works, images, research projects, and contact information for researchers and photographers. Gentian species occur around the world and have many different names, for example: centaury, çentiyane, chirayta, chirata, and chiretta, Encian, Enzian, fever tree, genciana, gentian, gentiane, genziane, long dan ke, pua keni keni, rindo, and tembusu. Gentians are gorgeous and have been used for millenia in horticulture, as medicines, and are also important in ecosystems as food sources for butterflies, nectar sources for pollinators, and many other functions. ...

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 site provides access to the Missouri Botanical Garden's VAST (VAScular Tropicos) nomenclatural database and associated authority files. Enter a scientific name in the box below to obtain current information on the name, its place of publication, type, and other information about the plant. Examples of name entries would be Poa, Olyra latifolia, Acacia baueri aspera. ... [Information of the supplier]
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. ...
