A quantitative trait locus (QTL) controlling shoot differentiation from immature embryo callus was identified by linkage analysis with morphological and isozyme markers in barley, Hordeum vulgare L. Immature embryos were isolated from cvs ‘Azumamugi’ (difficult to differentiate), ‘Kanto Nakate Gold’ (easy to differentiate), their hybrids (F1) and a(More)
The locus Shd1, which we previously mapped to the long arm of chromosome 2 of Hordeum vulgare L., controls the differentiation of shoots from immature barley embryo callus. The locus has major effects and its action explains more than 65% of the total genetic variance in the shoot-differentiation rate. The allele of cultivar Kanto Nakate Gold designated(More)
Mongolian gerbils are frequently used to study Helicobacter pylori-induced gastritis and its consequences. The presence of some gastric microbiota with a suppressive effect on H. pylori suggests inhibitory gastric bacteria against H. pylori infection. The aim of the present study was to analyze the microbiota in the stomach of Mongolian gerbils with H.(More)
