In contrast, science requires universality from us. However, until the end of 20th century, there was no such a common forum for chromosome science in Asia. In 1998, while the 18th International Congress of Genetics was being held in Beijing, China, chromosome researchers attending from Japan (Dr. Kiichi Fukui), China (Dr. Youzhi Ma), Korea (Prof. Jae-Wook Bang) and Th ailand (Dr. Somsac Apisitwanich) discussed the possibility of creating an Asian forum for chromosome researchers. An enthusiastic discussion followed and unanimously concluded with the decision to have the first Asian Chromosome Colloquium (ACC) at Beijing. One of the reasons why an ACC was agreed upon is that there was already a long tradition of bilateral conferences between China and Japan initiated in 1987 at Beijing (Hong 1989) and in 1992 at Tianjin (Tanaka 1992) by Profs. Hao Shui (Northeast Normal Univ.), Chen Ruiyang, (Tianjin Univ.), Hong Deyuan (Inst. Botany, Academia Sinica) Ryuso Tanaka, Kenji Taniguchi, and Masashi Nakata (Hiroshima Univ.).

The C-blocks were GC-rich in P. abramus , AT/GC-balanced in M. meltada , and AT-rich in A. argenteus , as revealed by fluorescent staining with quinacrine mustard (QM) and chromomycin A 3 (CMA). P. abramus conspicuously undercondensed, irrespective of autosomes or gonosomes, in all C-band regions including C-blocks. The extent of UC was most prominent in P. abramus , rather weak in M. meltada , and weakest in A. argenteus , suggesting a close relation to the amount of GC base pairs contained in C-heterochromatin. Thus 5-aza-dC treatment may be an easy method for detect-ing GC-rich heterochromatin. The appropriate conditions for inducing UC in the C-blocks were 10 -5 –10 -6 M and 2–3 hours. The decondensing effect of 5-aza-dC on the C-blocks was time- and concentration-dependent in all species examined, asynchronously acting with certain time lag between the early-replicating X and late-repli-cating X. The heteromorphic UC between the C-blocks of the XX homologue was observed with a frequency of 8% at maximum, reflecting the allocyclic behavior of the C-blocks.","PeriodicalId":10221,"journal":{"name":"Chromosome science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81462146","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}
