Background: Functional annotations of large plant genome projects mostly provide information on gene function
and gene families based on the presence of protein domains and gene homology, but not necessarily in
association with gene expression or metabolic and regulatory networks. These additional annotations are necessary
to understand the physiology, development...
Gramene (http://www.gramene.org) is a comparative genome mapping database for grasses and a community resource for rice. Rice, in addition to being an economically important crop, is also a model monocot for understanding other agronomically important grass genomes. Gramene replaces the existing AceDB database ‘RiceGenes’ with a relational database based on...
Gramene (http://www.gramene.org/) is a comparative genome database for cereal crops
and a community resource for rice. We are populating and curating Gramene with
annotated rice (Oryza sativa) genomic sequence data and associated biological information
including molecular markers, mutants, phenotypes, polymorphisms and Quantitative Trait
Loci (QTL). In order to support queries...
Rice, maize, sorghum, wheat, barley and the other
major crop grasses from the family Poaceae
(Gramineae) are mankind’s most important source
of calories and contribute tens of billions of dollars
annually to the world economy (FAO 1999, http://www.fao.org; USDA 1997, http://www.usda.gov).
Continued improvement of Poaceae crops is necessary
in order...
Now in its 10th year, the Gramene database (http://www.gramene.org) has grown from its primary focus on rice, the first fully-sequenced grass genome, to become a resource for major model and crop plants including Arabidopsis, Brachypodium, maize, sorghum, poplar and grape in addition to several species of rice. Gramene began with...
A framework for understanding the synthesis and catalysis of metabolites and other biochemicals by proteins is crucial for unraveling the physiology of cells. To create such a framework for Zea mays L. subsp. mays (maize), we developed MaizeCyc, a metabolic network of enzyme catalysts, proteins, carbohydrates, lipids, amino acids, secondary...
The Arabidopsis Information Portal (AIP), a resource expected to provide access to all community data and combine outputs into
a single user-friendly interface, has emerged from community discussions over the last 23 months. These discussions began
during two closely linked workshops in early 2010 that established the International Arabidopsis Informatics...
The Plant Ontology Consortium (POC) (www.plantontology.org) is a collaborative
effort among several plant databases and experts in plant systematics, botany
and genomics. A primary goal of the POC is to develop simple yet robust
and extensible controlled vocabularies that accurately reflect the biology of plant
structures and developmental stages. These...
Plant growth stages are identified as distinct morphological landmarks in a continuous developmental process. The terms
describing these developmental stages record the morphological appearance of the plant at a specific point in its life cycle. The
widely differing morphology of plant species consequently gave rise to heterogeneous vocabularies describing growth...
Formal description of plant phenotypes and standardized annotation of gene expression and protein localization data require
uniform terminology that accurately describes plant anatomy and morphology. This facilitates cross species comparative
studies and quantitative comparison of phenotypes and expression patterns. A major drawback is variable terminology that is
used to describe...
