Significant interspecific variation in DNA amount was observed among nine species of Piper. The DNA amount of a wild octoploid accession of Piper nigrum was approximately double that of the cultivated tetraploid variety of the same species. However, three New World diploid species had higher nuclear DNA amounts than several New or Old World tetraploid species. The DNA content per basic genome was, on the whole, lower in cultivated than in wild species.Key words: Piperaceae, Piper, Piper nigrum (black pepper), polyploids, DNA amounts.

Nuclear DNA amounts of 28 species of Senecio native to Australia and of four exotic species are reported. DNA amounts per 4C nucleus range from 4.22 pg to 42.90 pg, a 10-fold difference. Some of the variation is due to polyploidy as chromosome numbers range from n = 5 (by dysploid reduction) to n = 50, but DNA amounts per genome also vary from 0.84pg to 4.69 pg, a 6-fold difference. DNA amounts correlate with cell size and, in some instances, the size of structures. There is also a correlation between DNA amount and generation length which corresponds with previous observations.

Recent molecular studies in the genera Aegilops and Triticum showed that allopolyploidization (interspecific or intergeneric hybridization followed by chromosome doubling) generated rapid elimination of low-copy or high-copy, non-coding and coding DNA sequences. The aims of this work were to determine the amount of nuclear DNA in allopolyploid species of the group and to see to what extent elimination of DNA sequences affected genome size. Nuclear DNA amount was determined by the flow cytometry method in 27 natural allopolyploid species (most of which were represented by several lines and each

The B-chromosome and C-band numbers were determined in 12 Arizona Indian maize populations. These populations were originally collected from altitudes ranging from 100 to 5300 ft (1 ft = 0.3048 m). In addition, the total nuclear DNA amounts of these populations have been observed to vary by as much as 20%. The number of B-chromosomes was not significantly correlated with altitude, C-band number, or nuclear DNA amount. C-band number was significantly correlated with both altitude and genome size. It does not appear that the amount of C-band variation can account for the large nuclear DNA variat

Controversy regarding the restoration of eroded telomere length of donor cells after the nuclear transfer process has arisen from previous studies of cloned cattle, mice, and pigs. Little is known about telomere lengths in dogs from either natural breeding or somatic cell nuclear transfer (SCNT). In this study, we investigated the amount of telomeric DNA (ATD) in the lymphocytes of growing dog clones and their somatic cell donors.

This chapter deals with the similarities and differences between Homo neanderthalensis and Homo sapiens, by considering genetic, brain, and cognitive evidence. The genetic differentiation emerges from fossil genetic evidence obtained first from mtDNA and later from nuclear DNA. With high throughput whole genome sequencing, sequences have been obtained from the Denisova Cave (Siberia) fossils. Nuclear DNA of a third species (“Denisovans”) has been obtained from the same cave and used to define the phylogenetic relationships among the three species during the Upper Palaeolithic.

AbstractThis chapter describes characteristic features of the chromosomes and genomes of Triticeae species. Centromeres contain typical CENH3 nucleosomes, but these are associated with repeats that are larger than in other plant species. The sub-telomeric ends are rich in transposable elements and contain diverse repeats and recombination hotspots. The nucleolar organizer regions contain hundreds or thousands of ribosomal genes, rDNA repeats, arranged in tandem arrays that form a constriction known as the nucleolar organizer (NOR). We describe their mapping as well as the phenomenon known as N

Abstract The plastome is usually considered a highly conserved genome. Compared with the nuclear genome, it is small and has different genetic rules. Through different molecular methods (TILLING, candidate gene sequencing, amplicon massive sequencing and plastome re-sequencing) applied to barley chloroplast mutator (cpm) seedlings, we detected more than 60 polymorphisms affecting a wide variety of plastid genes and several intergenic regions. The genes affected belonged mostly to the plastid genetic machinery and the photosynthetic apparatus, but there were also genes like matK, whose function

Cancer assessment is of paramount importance as it encompasses understanding the nature of cancer, risk evaluation, prevention strategies, and health management. A tumor denotes an abnormal proliferation of cells lacking functional purpose and without the potential to metastasize to adjacent cells, organs, or distant parts of the body; hence, not all tumors are malignant, with benign tumors exhibiting non-invasive characteristics. The etiology of benign tumors remains somewhat elusive; however, genetic predispositions, poor dietary choices, exposure to radiation or toxins, occupational stress,

Abstract Normally in eukaryotes each allele of a gene contributes an equal amount of gene product. However, mammals exhibit an unusual phenomenon in which the expression level of the alleles of a subset of genes depends upon the parent from which the alleles were inherited. This phenomenon is called genomic imprinting and probably affects only a small number of genes (Efstratiadis 1994). One consequence of imprinted genes is the failure of uniparental mammalian embryos to develop normally. Embryos with two maternal pronuclei would be missing genes that are expressed exclusively from the patern

Abstract The mitotic cell cycle consists of interphase and a mitotic cell division (M-phase) when equal numbers of chromatids are partitioned into two daughter cells. Generally, the majority of a proliferating cell’s life is spent in interphase during which a doubling of DNA amount occurs (the duplication of each chromatid into a chromosome). This key event (DNA synthetic (S)-phase) is normally separated in time from mitosis by Gl (pre-synthetic interphase) and G2 (post-synthetic interphase). During interphase, the cell grows, the cell’s mass doubles, and the chromosomes contract progressively
