Grains of knowledge: genomics of model cereals.
The economic and scientific importance of the cereals has motivated a rich history of research into their genetics, development, and evolution. The nearly completed sequence of the rice genome is emblematic of a transition to high-throughput genomics and computational biology that has also pervaded study of many other cereals. The relatively close (ca. <50 million years old) relationships among...
متن کاملFunctional genomics of abiotic stress tolerance in cereals.
Abiotic stresses such as extreme temperatures, low water availability, high salt and mineral deficiencies or toxicities severely diminish productivity of cereal crops. These stresses are becoming increasingly important because of the declining availability of good quality water, land degradation and community pressures to move away from chemical intervention in agriculture. Of the major cereals...
متن کاملA versatile transposon-based activation tag vector system for functional genomics in cereals and other monocot plants.
Transposon insertional mutagenesis is an effective alternative to T-DNA mutagenesis when transformation through tissue culture is inefficient as is the case for many crop species. When used as activation tags, transposons can be exploited to generate novel gain-of-function phenotypes without transformation and are of particular value in the study of polyploid plants where gene knockouts will no...
متن کاملAdvances in functional genomics for investigating salinity stress tolerance mechanisms in cereals
Abiotic stresses such as low water availability and high salinity are major causes of cereal crop yield losses and significantly impact on sustainability. Wheat and barley are two of the most important cereal crops (after maize and rice) and are grown in increasingly hostile environments with soil salinity and drought both expected to increase this century, reducing the availability of arable l...
متن کاملObservation of Extensive Chromosome Axis Remodeling during the “Diffuse-Phase” of Meiosis in Large Genome Cereals
The production of balanced fertile haploid gametes requires the faithful separation of paired (synapsed) chromosomes toward the end of meiotic prophase I (desynapsis). This involves the timely dissolution of the synaptonemal complex during the pachytene-diplotene transition, a stage traditionally referred to as the "diffuse stage." In species with large genomes such as, barley (Hordeum vulgare ...
