In this study, 68 plants of P. yedoensis grown in 46 prefectures in Japan were investigated. All the P. yedoensis individuals investigated showed the completely same banding pattern, indicating their clonal origin from a single plant. On the other hand, each of P. lannesiana and P. pendula individuals investigated showed a unique banding pattern, suggesting a considerable amount of genetic variation in these two species. About 90% of bands in DNA fingerprints of P. yedoensis were detected in either P. lannesiana or P. pendula. This result supports the hypothesis that P. yedoensis is an interspecific hybrid between P. lannesiana and P. pendula. From those results, it is concluded that P. yedoensis was produced only once through hybridization between P. lannesiana and P. pendula, and that this particular hybrid plant has been spread vegetatively all over Japan.","PeriodicalId":13120,"journal":{"name":"Idengaku zasshi","volume":"70 2","pages":"185-96"},"PeriodicalIF":0.0,"publicationDate":"1995-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1266/jjg.70.185","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18611484","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}

Chiasma graphs are developed for three mammals with greatly different chromosome numbers: Chinese hamster (with n = 11), mice (n = 20), and a dog (n = 39). The results demonstrate that interstitial chiasmata can contribute both to gene shuffling and to the binding of bivalents, but that so-called terminal chiasmata are in fact mostly achiasmatic terminal associations, the main function of which is to bind bivalents. For this reason, terminal chiasmata should be excluded when chiasma frequency is estimated. It is also demonstrated that interstitial chiasmata distribute on bivalents randomly and uniformly, except at the centromere and telomere. Interference distance fluctuates almost randomly above a minimum value equivalent to about 1.8% of total bivalent length at diakinesis. These results indicate that chiasma formation in mammals is principally a random event. The demonstrated minimum interference distance seems consistent with the polymerization model for chiasma formation. Some cytological aspects of crossing-over are discussed with reference to the minimum interaction theory for eukaryotic chromosome evolution.","PeriodicalId":13120,"journal":{"name":"Idengaku zasshi","volume":"70 2","pages":"233-65"},"PeriodicalIF":0.0,"publicationDate":"1995-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1266/jjg.70.233","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18611488","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}

Although courtship can be easily monitored and quantified, little is known about its neural basis. To obtain a better understanding of cellular and molecular mechanisms underlying courtship, we have isolated mutants that disrupt specific aspects of mating behavior. The croaker mutant was isolated from approximately 1,000 lines harboring single P-element insertions by screening for aberrant courtship song: croaker males often generate polycyclic pulse song while most of the song pulses are monocyclic in the wild-type. The mutant is also defective in flight. Intracellular recordings of excitatory junction potentials from larval body wall muscles and Ca++ action potentials from adult indirect flight muscles demonstrated that neuromuscular transmission and Ca++ electrogenesis in the muscle fibers are not impaired by the croaker mutation. To define the croaker gene molecularly, genomic DNA surrounding the P-element insertion site was cloned by plasmid rescue and subsequent screening of a cosmid library. Northern blotting with the genomic DNA probes detected three transcripts in the wild-type, which were not expressed in the croaker mutant.","PeriodicalId":13120,"journal":{"name":"Idengaku zasshi","volume":"70 1","pages":"103-17"},"PeriodicalIF":0.0,"publicationDate":"1995-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1266/jjg.70.103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18772296","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}

Plant morphologies of the hybrids strongly resembled the tetraploid Oryza species. Five hybrids obtained from the four cross-combinations had the expected chromosome number of 2n = 36 (trihaploid) in the somatic cells. The average meiotic chromosome pairings per cell were 0.23II + 35.58I + 0.14(1)/2I (dividing univalent) for O. punctata x L. tisseranti; 0.11II + 35.51I + 0.22(1)/2I for O. punctata x L. perrieri; 0.17II + 35.63I + 0.11(1)/2I for O. latifolia x L. tisseranti; and 0.25II + 35.49I + 0.15(1)/2I for O. latifolia x L. perrieri. From these results, it seems that most of the bivalents observed at MI with a low frequency had originated from the autosyndetic association of the chromosomes of O. punctata or O. latifolia. The results described above suggest that there is no genomic relationship between the parental species in each cross combination.","PeriodicalId":13120,"journal":{"name":"Idengaku zasshi","volume":"70 1","pages":"47-55"},"PeriodicalIF":0.0,"publicationDate":"1995-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1266/jjg.70.47","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18772194","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}
