Microsatellite (simple sequence repeat – SSR) and single nucleotide polymorphism (SNP) markers are two types of important genetic markers useful in genetic mapping and genotyping. Often, large-scale genomic research projects require high-throughput computer-assisted primer design. Numerous such web-based or standard-alone programs for PCR primer design are(More)
We have developed an automated, high-throughput fingerprinting technique for large genomic DNA fragments suitable for the construction of physical maps of large genomes. In the technique described here, BAC DNA is isolated in a 96-well plate format and simultaneously digested with four 6-bp-recognizing restriction endonucleases that generate 3' recessed(More)
Because of the huge size of the common wheat (Triticum aestivum L., 2n = 6x = 42, AABBDD) genome of 17,300 Mb, sequencing and mapping of the expressed portion is a logical first step for gene discovery. Here we report mapping of 7104 expressed sequence tag (EST) unigenes by Southern hybridization into a chromosome bin map using a set of wheat aneuploids and(More)
Bread wheat (Triticum aestivum) is a globally important crop, accounting for 20 per cent of the calories consumed by humans. Major efforts are underway worldwide to increase wheat production by extending genetic diversity and analysing key traits, and genomic resources can accelerate progress. But so far the very large size and polyploid complexity of the(More)
Two high-molecular-weight subunit (HMWS) glutenin genes from the A and B genomes of the hexaploid bread wheat Triticum aestivum L. cv Cheyenne have been isolated and sequenced. Both of these genes are of the high Mr class (x-type) of HMW glutenins, and have not been previously reported. The entire set of six HMW genes from cultivar Cheyenne have now been(More)
High-molecular-weight glutenin subunits (HMW-GS), one class of seed storage proteins, are important determinants of the bread-making quality of wheat flour. To change the amount and composition of these proteins via genetic engineering, a gene encoding a novel hybrid subunit under the control of native HMW-GS regulatory sequences was inserted into wheat. Of(More)
We have used the maize ubiquitin 1 promoter, first exon and first intron (UBI) for rice (Oryza sativa L. cv. Taipei 309) transformation experiments and studied its expression in transgenic calli and plants. UBI directed significantly higher levels of transient gene expression than other promoter/intron combinations used for rice transformation. We exploited(More)
Durum wheat (Triticum turgidum ssp. durum, 2n = 4x = 28, genomes AB) is an economically important cereal used as the raw material to make pasta and semolina. In this paper we present the construction and characterization of a bacterial artificial chromosome (BAC) library of tetraploid durum wheat cv. Langdon. This variety was selected because of the(More)
Single-nucleotide polymorphism was used in the construction of an expressed sequence tag map of Aegilops tauschii, the diploid source of the wheat D genome. Comparisons of the map with the rice and sorghum genome sequences revealed 50 inversions and translocations; 2, 8, and 40 were assigned respectively to the rice, sorghum, and Ae. tauschii lineages,(More)
