Three types of zymogram were detected in 39 strains of Triticum monococcum and three other different types were detected in another diploid wheat, T. urartu. Two varieties of Ae. speltoides, var. ligustica and var. aucheri (subsection Truncata), were similar to each other and showed wide variation of zymograms. Sixteen strains of Ae. longissima and 13 strains of Ae. sharonensis were each grouped into four types. Ten strains of Ae. bicornis were grouped into three types, each including three or four strains. On the other hand, zymograms from five strains of Ae. searsii, which was formerly treated as a variety of Ae. longissima, were very different from those of Ae. longissima. In contrast to subsection Truncata, the zymogram types were rather simple and similar among species in subsection Emarginata (Ae. longissima, Ae. sharonensis, and Ae.bicornis) except for Ae. searsii. Finally, the phylogeny of tetraploid wheat was discussed on the basis of the results presented here along with those of the previous authors.","PeriodicalId":22578,"journal":{"name":"The Japanese Journal of Genetics","volume":"24 1","pages":"1-15"},"PeriodicalIF":0.0,"publicationDate":"1992-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76760559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Growth vigor of the alloplasmic lines was influenced more by cytoplasm donors than by nucleus donors, while male sterility was influenced more by nucleus donors. Short-arm telocentric, nucleolus-organizing chromosomes (telosomes) derived from Agropyron caused the restoration of growth vigor and male fertility of the alloplasmic lines in which cytoplasms and telosomes from the same Agropyron species were combined. The telosomes derived from Agropyron species different from the cytoplasm donors could also recover growth vigor and male fertility of the alloplasmic lines. The result indicates the presence of a common mechanism(s) which controls the nucleus-cytoplasmic incompatibility expressed in the alloplasmic lines with the two Agropyron cytoplasms. The Agropyron telosomes showed some dosage effects on growth vigor of the alloplasmic lines and affected fertility when added to the nuclear backgrounds of the two common wheat cultivars.","PeriodicalId":22578,"journal":{"name":"The Japanese Journal of Genetics","volume":"37 1","pages":"133-145"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85827363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oono","doi":"10.1266/JJG.67.321","DOIUrl":"https://doi.org/10.1266/JJG.67.321","url":null,"abstract":"Rice (Oryza sativa L. var. Nipponbare) seeds, seedlings and suspension callus were subjected to powerful gravity stress ranging from 150,000 g to 450,000 g. Suspension callus and dehulled seeds showed 32% and 15% survival rates, respectively, after gravity treatment at 450,000 g for 6 hours, whereas all the seedlings died. Seedlings became increasingly sensitive to gravity stress as the growth stage advanced. The suspension callus, which gradually recovered viability during subculture under normal conditions, were used to analyze the protein patterns and in vitro translation products of poly(A)+RNA. Some 3 to 4 newly synthesized proteins and in vitro translation products were identified using two-dimensional electrophoresis, while 5 to 24 proteins disappeared during the treatment, demonstrating that rice suspension callus respond to gravity stress by producing new mRNA and their proteins. In addition, some newly synthesized proteins which resulted from gravity effects were maintained in the surviving cells during continuous growth on solid medium. There was an increase in the survival rate of suspension callus from the strong gravity stress as a result of treatment with 200 g/l sucrose, 10-5 M ABA or 5 g/l NaCl. This suggests that in addition to changes in protein patterns, another protection mechanism associated with some physiological changes is involved in the survival of rice suspension callus after gravity stress.","PeriodicalId":22578,"journal":{"name":"The Japanese Journal of Genetics","volume":"1 1","pages":"321-334"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90238353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
