Chromosome morphology was studied in lily genotypes L. candidum, L. × formolongi, L. henryi and L. pumilum, and cultivars ‘Alma Ata,’ ‘Expression,’ ‘Marco Polo,’ ‘Muscadet’ and ‘Star Gazer’ belonging to the horticultural group Oriental hybrids. All genotypes tested represented 2n = 2x = 24 chromosomes. Chromosomal markers were established after Feulgen and silver staining, from analysis of the ...

Maintaining the length of the telomere tract at chromosome ends is a complex process vital to normal cell division. Telomere length is controlled through the action of telomerase as well as a cadre of telomere-associated proteins that facilitate replication of the chromosome end and protect it from eliciting a DNA damage response. In vertebrates, multiple poly(ADP-ribose) polymerases (PARPs) ha...

Sixty normal male Caucasians were selected to study the length of the Y chromosome. QFQ banding was performed. Chromosomes 19 and 20 (F) and Y were measured directly from the film. Y/F, f/F, and nf/F indices (f = fluorescent; nf = non-fluorescent segment) were determined. The length of the Y chromosome was classified into 5 groups; very small, small, average, large, and very large with Y/F indi...

The stochasticity of chromosome organization was investigated by fluorescently labeling genetic loci in live Escherichia coli cells. In spite of the common assumption that the chromosome is well modeled by an unstructured polymer, measurements of the locus distributions reveal that the E. coli chromosome is precisely organized into a nucleoid filament with a linear order. Loci in the body of th...

We present a genome assembly from an individual male Lysandra coridon (the Chalkhill Blue; Arthropoda; Insecta; Lepidoptera; Lycaenidae). The sequence is 541 megabases in span. Most of the scaffolded into 90 chromosomal pseudomolecules, including assembled Z sex chromosome. mitochondrial has also been and 15.4 kilobases length. Gene annotation this on Ensembl ide...

We present a genome assembly from an individual male Zeuzera pyrina (the Leopard Moth, Arthropoda; Insecta; Lepidoptera; Cossidae). The sequence is 687 megabases in span. Most of the scaffolded into 31 chromosomal pseudomolecules, including assembled Z sex chromosome. mitochondrial has also been and 15.3 kilobases length. Gene annotation this on Ensembl identifie...

In this study, chromosome length, karyomorphology and asymmetry of six Turkish Muscari species; muglaensis, M. nazimiyensis, pallens, pamiryigidii, inundatum fatmaceranie were evaluated. The somatic number all examined taxa was determined as 2n=18. basic x=9. Chromosomes consist metacentric, submetacentric, subtelocentric chromosomes. This is the first report on morphology for five studied. Stu...

It is known that total telomere length is shorter in invasive breast cancer than in normal breast tissue but the status of individual telomere lengths has not been studied. Part of the difficulty is that usually telomere length in interphase cells is measured on all chromosomes together. In this study we compared normal breast epithelium, duct carcinoma in situ (DCIS), and invasive duct carcino...

Kinesin-8 motor proteins destabilize microtubules. Their absence during cell division is associated with disorganized mitotic chromosome movements and chromosome loss. Despite recent work studying effects of kinesin-8s on microtubule dynamics, it remains unclear whether the kinesin-8 mitotic phenotypes are consequences of their effect on microtubule dynamics, their well-established motor activi...

Physical interactions between distinct chromosomal genomic loci are important for genomic functions including recombination and gene expression, but the mechanisms by which these interactions occur remain obscure. Using telomeric association as a model system, we analyzed here the in vivo organization of chromosome ends of haploid yeast cells during interphase. We separately labeled most of the...
