    Analysis of the barley chromosome 2 region containing the six-rowed spike gene vrs1 reveals a breakdown of rice–barley micro collinearity by a transposition

    In cultivated barley (Hordeum vulgare ssp. vulgare), six-rowed spikes produce three times as many seeds per spike as do two-rowed spikes. The determinant of this trait is the Mendelian gen...

    Inter-subspecific maps of non-brittle rachis genes btr1/btr2 using occidental, oriental and wild barley lines

    Brittle rachis of wild barley is controlled by two dominant complementary genes, Btr1 and Btr2, and mutation in either locus (btr1 or btr2) results in the non-brittle rachis of cultivated barley. In this study, a...

    Structural and distributional variation of mitochondrial rps2 genes in the tribe Triticeae (Poaceae)

    The mitochondrial rps2 gene from barley, like that of rice, wheat, and maize, has an extended open reading frame (ORF) at the 3′-region when compared to that from lower plants. However, the extended portions are ...

    High-density AFLP map of nonbrittle rachis 1 (btr1) and 2 (btr2) genes in barley (Hordeum vulgare L.)

    Wild relatives of barley disperse their seeds at maturity by means of their brittle rachis. In cultivated barley, brittleness of the rachis was lost during domestication. Nonbrittle rachis of occidental barley...

    Identification and map** of cleistogamy genes in barley

    Cleistogamy is a closed type of flowering with ensured self-pollination and an important trait to study evolutionary development in flower organs, reproduction systems, gene flow, and disease control. Still, v...

    Identification of QTLs controlling tissue-culture traits in barley (Hordeum vulgare L.)

    Quantitative trait loci (QTLs) controlling callus growth (CG), subsequent shoot differentiation ratio (SD) and green shoot ratio (GS) in immature embryo culture were identified in barley. A base map was develo...

    Molecular map** of the intermedium spike-c (int-c) and non-brittle rachis 1 (btr1) loci in barley (Hordeum vulgare L.)

    Lateral spikelet fertility and a non-brittle rachis are key characters in studying the evolution of barley. The fertility of lateral spikelets is controlled predominantly by the alleles at the vrs1 locus on chrom...

    A DNA marker closely linked to the vrs1 locus (row-type gene) indicates multiple origins of six-rowed cultivated barley (Hordeum vulgare L.)

    The origin of six-rowed cultivated barley was studied using a DNA marker cMWG699 closely linked to the vrs1 locus. Restriction patterns of the PCR-amplified product of the cMWG699 locus were examined in 280 culti...

    Molecular map** of a fertility restoration locus (Rfm1) for cytoplasmic male sterility in barley (Hordeum vulgare L.)

    The Rfm1a gene restores the fertility of msm1 cytoplasmic male-sterile lines in barley. We identified three RAPD markers linked to the Rfm1 locus (CMNB-07/800, OPI-18/900, and OPT-02/700) using isogenic lines and...
