Genomic Databases for Crop Improvement
Genomics is playing an increasing role in plant breeding and this is accelerating with the rapid advances in genome technology. Translating the vast abundance of data being produced by genome technologies requires the development of custom bioinformatics tools and advanced databases. These range from large generic databases which hold specific data types for a broad range of species, to careful...
متن کاملMinichromosomes: Vectors for Crop Improvement
Minichromosome technology has the potential to offer a number of possibilities for expanding current biofortification strategies. While conventional genome manipulations rely on random integration of one or a few genes, engineered minichromosomes would enable researchers to concatenate several gene aggregates into a single independent chromosome. These engineered minichromosomes can be rapidly ...
متن کاملMutation discovery for crop improvement.
Increasing crop yields to ensure food security is a major challenge. Mutagenesis is an important tool in crop improvement and is free of the regulatory restrictions imposed on genetically modified organisms. The forward genetic approach enables the identification of improved or novel phenotypes that can be exploited in conventional breeding programmes. Powerful reverse genetic strategies that a...
متن کاملPolyploidy and Crop Improvement
All crop plants are polyploid and some genomes have been duplicated more recently than others. Advancements in cytogenetic and molecular tools, including high-density genetic mapping, fl orescent in situ hybridization, and genome and EST sequencing, have enabled new insights into genome composition and the history of genome duplications in crop plants. We review this evidence and discuss the re...
متن کاملUntapping root system architecture for crop improvement
Roots are the first organ to sense water deficit, and at the same time they extract virtually all those mineral nutrients from soil that are consumed by humans. Soil resource acquisition under challenging conditions such as drought is a primary limitation on plant productivity, resulting in low yields and thus food insecurity in the poorest countries. Indeed, in overall global agriculture, drou...
