“…Soybean has been used as a food and a drug component in China for thousands of years [2] and over the past 60 years has become a leading crop in many nations around the world [3]. Because of its high value in the agricultural and food industry, soybean has received greater and greater research attention, both to improve soybean agronomic performances and as a model for basic biological studies.…”

BackgroundTranscription factors play the crucial rule of regulating gene expression and influence almost all biological processes. Systematically identifying and annotating transcription factors can greatly aid further understanding their functions and mechanisms. In this article, we present SoyDB, a user friendly database containing comprehensive knowledge of soybean transcription factors.DescriptionThe soybean genome was recently sequenced by the Department of Energy-Joint Genome Institute (DOE-JGI) and is publicly available. Mining of this sequence identified 5,671 soybean genes as putative transcription factors. These genes were comprehensively annotated as an aid to the soybean research community. We developed SoyDB - a knowledge database for all the transcription factors in the soybean genome. The database contains protein sequences, predicted tertiary structures, putative DNA binding sites, domains, homologous templates in the Protein Data Bank (PDB), protein family classifications, multiple sequence alignments, consensus protein sequence motifs, web logo of each family, and web links to the soybean transcription factor database PlantTFDB, known EST sequences, and other general protein databases including Swiss-Prot, Gene Ontology, KEGG, EMBL, TAIR, InterPro, SMART, PROSITE, NCBI, and Pfam. The database can be accessed via an interactive and convenient web server, which supports full-text search, PSI-BLAST sequence search, database browsing by protein family, and automatic classification of a new protein sequence into one of 64 annotated transcription factor families by hidden Markov models.ConclusionsA comprehensive soybean transcription factor database was constructed and made publicly accessible at http://casp.rnet.missouri.edu/soydb/.

“…Genes encoding these toxins have been incorporated into genetically modiWed (GM) crops such as cotton and maize (Shelton et al, 2002). The consequences of the application of insect resistant GM crops are several; one notable advantage has been the reduction in use of broadspectrum insecticides (Pyke and Fitt, 1998;Pray et al, 2002;Carpenter et al, 2004;Hails and Raymond, 2004), a pattern accompanied by some evidence for increasing reliance on natural enemies and biological control (EPA, 2001).…”

“…For example, the NewLeaf® potato variety marketed by Monsanto contains a modified cry3A toxin gene. It demonstrated very effective control of the Colorado potato beetle and allowed a 40 % reduction in pesticide applications (Carpenter & Gianessi, 2001). In the case of YieldGuard® maize, there has been effective control of the target pest (the European corn borer; Ostrinia nubilalis) but only a small reduction in pesticide use (1·5 %) reflecting the fact that pesticides are ineffective against this species and are rarely used (Carpenter & Gianessi, 2001).…”

An important knock-on effect of the Bt maize variety was the reduction in insect-mediated feeding damage, which helped to limit adventitious access and further spoilage by fungal pathogens and mycotoxin contamination (Llewellyn & Higgins, 2002).…”

The potential of genetically enhanced plants to address food insecurity

2004

View full text Add to dashboard Cite

Food insecurity is one of the most important social issues faced today, with 840 million individuals enduring chronic hunger and three billion individuals suffering from nutrient deficiencies. Most of these individuals are poverty stricken and live in developing countries. Strategies to address food insecurity must aim to increase agricultural productivity in the developing world in order to tackle poverty, and must provide long-term improvements in crop yields to keep up with demand as the world's population grows. Genetically enhanced plants provide one route to sustainable higher yields, either by increasing the intrinsic yield capability of crop plants or by protecting them from biotic and abiotic constraints. The present paper discusses a range of transgenic approaches that could increase agricultural productivity if applied on a large scale, including the introduction of genes that confer resistance to pests and diseases, or tolerance of harsh environments, and genes that help to lift the intrinsic yield capacity by increasing metabolic flux towards storage carbohydrates, proteins and oils. The paper also explores how the nutritional value of plants can be improved by genetic engineering. Transgenic plants, as a component of integrated strategies to relieve poverty and deliver sustainable agriculture to subsistence farmers in developing countries, could have a significant impact on food security now and in the future.
