Paspalum cromyorrhizon Trin. ex Döll is a species adapted to low and humid fields, river and stream banks, throughout S Brazil, Uruguay and NE Argentine. Diploids (2n = 2x = 20) and tetraploids (2n = 4x = 40) from natural populations of P. cromyorrhizon from Corrientes (Argentina) were used to analyse the karyotype morphometry of both cytotypes. The chromosome count was performed using classical Feulgen staining.

The genus Trifolium L. is characterized by basic chromosome numbers 8, 7, 6, and 5. We conducted a genus-wide study of ribosomal DNA (rDNA) structure variability in diploids and polyploids to gain insight into evolutionary history. We used fluorescent in situ hybridization to newly investigate rDNA variation by number and position in 30 Trifolium species. Evolutionary history among species was examined using 85 available sequences of internal transcribed spacer 1 (ITS1) of 35S rDNA. In diploid species with ancestral basic chromosome number (x = 8), one pair of 5S and 26S rDNA in separate or ad

ABSTRACT Saccharomyces cerevisiae diploids homozygous for the rad52-1 mutation have previously been shown to lose chromosomes mitotically. Spontaneous events and events following low levels of X-ray or methyl methanesulfonate treatment result in monosomic diploids, whereas higher levels of treatment result in near haploidization. This rad52-1-dependent chromosome loss has been used to develop a new mapping method which can be used to assign a previously unmapped gene to a chromosome. Chromosome loss mapping can be done in either of two ways: (1) if a diploid, homozygous for rad52-1 but heteroz

Additive and multiplicative effects of colchicine treatment at the seedling stage and of chromosome doubling on chromosome-specific chiasma frequency at metaphase I have been measured in comparisons between C0 and untreated diploids and between C0 autotetraploids and C0 diploids. Early colchicine treatment increases the frequency of chromosome C univalents to 1.8% but has no similar effect on chromosomes A and D. Colchicine treatment has little net effect on mean chiasma frequency, deducting an average of 0.204 chiasmata per set but otherwise multiplying the mean by a factor of 1.182. These ad

Cytological and molecular genetic analyses were carried out in both diploids and triploids that were collected from 55 geographical locations in Korea, Japan, and China. While the 5S rRNA gene loci were located at duplicated loci on the long arm of chromosome 2, the 45S rRNA gene loci were present in chromosomes 1, 2, 4, 6, 7, and 11.

Morphologically, these plants with 18 chromosomes were qualitatively similar to normal diploids (2n = 14), in spite of a duplication of a small proximal segment of the short arm of chromosome 3.

Abstract In wild-type strains of Neurospora crassa, the rDNA is located at a single site in the genome called the nucleolus organizer region (NOR), which forms a terminal segment on linkage group (LG) V. In the quasiterminal translocation strain T(I;V)AR190, most of the right arm of LG I moved to the distal tip of the NOR, and one or a few rDNA repeat units are moved to the truncated right arm of LG I. I report here that, in partial diploid strains derived from T(I;V)AR190, large terminal deletions result from chromosome breakage in the NOR. In most of these partial diploids, chromosome breaka

The goal is to determine the higher order structure of interphase chromosomes in these nuclei. Higher order structures include those structures larger than the 30nm fiber. Over the years, several general models for higher order chromosome structures have been presented. We look at three popular models for the organization of chromatin during embryogenesis, as each of these models make predictions that can be tested using high resolution in situ hybridization and imag

Here, we summarize the previous and on-going efforts in the US in the development of reference genomes for sweetpotato.

The effects of chromosome doubling per se generally have been viewed as maladaptive. Levin (1945) argued that chromosome doubling radically alters the balance of multiple factors acting on a single character and that only through hybridization and selection may this imbalance be restored.

One of the ways of improving the genotypes of dairy cattle in Russia is to increase the proportion of the Ayrshire breed, which can be justly claimed to be one of the best dairy breeds in the world. However, due to the prevalence of large-scale breeding technologies, which involves the use of a limited contingent of dairy cattle bulls, including but not limited to the Ayrshire breed, the emergence of new-born calves with various anomalies, including chromosomal, which commonly have a hereditary basis attributable to gene mutations have been observed. Given that the bulk of these anomalies are

Each year, significant global wheat yield loss occurs due to diseases that affect yield quantity or quality. Breeding for resistance has been the best economic and environmentally safe approach to control wheat diseases, however many disease resistance (R) genes succumbed to the pathogens and are no longer effective. Hence, new sources of resistance are necessary to boost the wheat gene pool. The main source for such genes are species of wheat wild relatives in the secondary gene pool that contain an unexploited reservoir of novel R genes. Sharon goatgrass (Aegilops sharonensis Eig) is a wild

The long-term motivation for this research is to transfer useful traits from a broad based gene pool of wild species into the narrow base of a cultivated crop in Cucumis. Our primary focus was to use polyploid prior to fertilization as a tool to overcome fertility barriers in the cross between C. melo and C. metuliferus. In conducting this research, we explored all combinations of tetraploid and diploid parents, in reciprocal combinations. Pollinations were made in both the field and greenhouse, using emasculated flowers, moneocious females, and open pollination by insect vectors, with morphol

1. Abstract: Over the past 25 years, vine cacti of the genera Hylocereus and Selenicereus have been introduced into Israel and southern California as new exotic fruit crops. The importance of these crops lies in their high water use efficiency and horticultural potential as exotic fruit crops. Our collaboration focused on the cytological, molecular and evolutionary aspects of vine cacti polyploidization to confront the agricultural challenge of genetic improvement, ultimately to improve success of vine cacti as commercial fruit crop plants. More specifically, we worked on the: 1- Identificatio
