Bread wheat (Triticum aestivum L.) is a hexaploid species with a large and complex genome. A reference genetic marker map, namely the International Triticeae Mapping Initiative (ITMI) map, has been constructed with the recombinant inbred line population derived from a cross involving a synthetic line. But it is not sufficient for a full understanding of the(More)
Removal of a selectable marker gene from genetically modified (GM) crops alleviates the risk of its release into the environment and hastens the public acceptance of GM crops. Here we report the production of marker-free transgenic rice by using a chemically regulated, Cre/loxP-mediated site-specific DNA recombination in a single transformation. Among 86(More)
Bacterial blight of rice, caused by Xanthomonas oryzae pv. oryzae (Xoo) (Ishyama) Dye, is one of the serious diseases prevalent throughout Asia. In a previous study, a resistance (R) locus was transferred from the tetraploid wild rice Oryza minuta to the cultivated rice species, Oryza sativa L. Here, we report the fine genetic mapping of the R locus,(More)
Kernel number per spike is one of the most important yield components of wheat. To map QTLs related to kernel number including spike length (SPL), spikelet number per spike (SPN), fertile spikelet number (FSPN), sterile spikelet number (SSPN) and compactness, and to characterize the inheritance modes of the QTLs and two-locus interactions, 136 recombinant(More)
Acidic soils inhibit crop yield and reduce grain quality. One of the major contributing factors to acidic soil is the presence of soluble aluminum (Al(3+)) ions, but the mechanisms underlying plant responses to Al(3+) toxicity remain elusive. Nitric oxide (NO) is an important messenger and participates in various plant physiological responses. Here, we(More)
 Interspecific asymmetric somatic hybrids have been produced between the sexually incompatible annual Medicago species Medicago truncatula and M. scutellata using only one regenerable parent and improved protoplast techniques. Regenerable M. truncatula leaf protoplasts were inactivated by lethal doses of iodoacetamide. Cotyledon protoplasts of(More)
A regenerable line of Medicago truncatula (Jemalong 2HA) as a recipient species, was fused with the sexually incompatible species Medicago scutellata or Medicago rugosa. The treatments described maintain the chromosome number of the recipient but enable the transfer of small amounts of DNA of the donor species, probably by intergenomic recombination.(More)
The most sustainable approach to control rice blast disease is to develop durably resistant cultivars. In molecular breeding for rice blast resistance, markers developed based on polymorphisms between functional and non-functional alleles of resistance genes, can provide precise and accurate selection of resistant genotypes without the need for difficult,(More)
Nitric oxide signal and GSNOR activity play an essential role for Chlamydomonas reinhardtii response to salt stress. The unicellular alga Chlamydomonas reinhardtii is one of the most important model organisms phylogenetically situated between higher plants and animals. In the present study, we used comparative proteomics and physiological approaches to(More)
