Inactivation of a suppressor gene by deletion of chromosome 9 is a candidate initiating event in bladder carcinogenesis. We have used 13 polymorphic markers spanning the length of chromosome 9 in order to map the region of deletion in human bladder carcinomas. In the majority of tumors loss of heterozygosity was found at all informative sites along the chromosome, indicating deletion of the ent...

The B chromosome of maize has been used in a study of dicentric chromosomes. TB-9Sb is a translocation between the B and chromosome 9. The B-9 of TB-9Sb carries 60% of the short arm of 9. For construction of dicentrics, a modified B-9 chromosome was used, B-9-Dp9. It consists of the B-9 chromosome plus a duplicated 9S region attached to the distal end. In meiosis, fold-back pairing and crossing...

Pseudomonas is a complex genus with increasing numbers of new species. Recently, we isolated sp. strain L22-9, which showed antifungal activity against several fungal phytopathogens. Here, report the whole genome sequence L22-9. Genomic analysis revealed that L22-9 contains one circular DNA chromosome 6,730,360 bp length 60.9% GC content. Bioinformatics identified gene clusters in synthesize an...

Pericentric inversion of the secondary constriction region (qh) of human chromosome 9 is a frequent occurrence. This structural alteration is regarded as a normal familial variant, termed heteromorphism, and is inherited in a Mendelian fashion without any apparent phenotypic consequences. We characterized the qh region of chromosome 9 from five individuals using a series of molecular cytogeneti...

In this study, the karyotypic characteristics of Chondrostoma regium (Heckel, 1843) have been investigated. Fish samples were caught from Karasu River (Euphrates Basin) with fishing net. The live fish transported to laboratory and kept in aerated aquaria before analyses. karyotype analysis was performed kidney gill epithelium cells. It determined that C. had 2n=50 chromosomes. detail, formula a...

Trisomy 9 can be suspected and confirmed in the prenatal period since the 11-13.6 weeks of screening. In cases of partial trisomy 9, the diagnosis is important especially to counseling the couple due to the increased likelihood of recurrence in subsequent pregnancies.

Chromosome 9 allelic losses have been reported as a frequent and early event occurring in bladder cancer. It has been postulated that a candidate tumor suppressor gene may reside on this chromosome, alterations of which may lead to the development of a subset of superficial bladder tumors. More recently, the involvement of two different regions harboring suppressor loci, one on each of both chr...
