Lepidopteran species have a relatively high number of small holocentric chromosomes (Bombyx mori, 2n = 56). Chromosome identification has long been hampered in this group by the high number and by the absence of suitable markers like centromere position and chromosome bands. In this study, we carried out fluorescence in situ hybridization (FISH) on meiotic chromosome complements using genetical...

The karyology of five species Boesenbergia (B. collinsii, B. pulcherrima, rotunda, thorellii and xyphostachya) (Zingiberaceae) in Thailand are investigated. chromosome number karyotype formula the 2n=20 (8m+10sm+2st) 2n=36 (8m+18sm+10st) 2n=38 (18m+14sm+6st) (30m+8sm with one satellite) 2n=22 (6m+6sm+10st two satellites) xyphostachya, respectively. Three pulcherrima have new chromosomal counts....

Purpose This study aims to determine whether, by means of the application genetic algorithms (GA) through traditional technical analysis (TA) using moving average convergence/divergence (MACD), is possible achieve higher yields than those that would be obtained investment strategies following a approach and buy hold (B&H) strategy. Design/methodology/approach The was carried out based on da...

cytotaxonomy is a branch of cytogenetics, devoted to the comparative study of karyological features for systematic and evolutionary purposes. surely, awareness of chromosomal characters increases our knowledge in different fields of studies. in this study, cytogenetic analyses were performed in 92 mus musculus specimens from 26 localities in iran. cytogenetic characteristics of the house mouse,...

Deer species of the genus Mazama show significant inter- and intraspecific chromosomal variation due to the occurrence of rearrangements and B chromosomes. Given that carriers of aneuploidies and structural rearrangements often show anomalous chromosome pairings, we here performed a synaptonemal complex analysis to study chromosome pairing behavior in a red brocket deer (Mazama americana) indiv...

We report a de novo -assembled draft genome sequence of the Indian Staphylococcus aureus type 88 (ST88) strain LVP-7, isolated from an ocular infection. The harbors Panton-Valentine leukocidin phage, V staphylococcal cassette chromosome mec element, delta-hemolysin-converting Newman phage ΦNM3, and pathogenicity island SaPI3, encoding superantigen enterotoxin B.

Plantago lagopus is a diploid (2n = 2x =12) weed belonging to family Plantaginaceae. We reported a novel B chromosome in this species composed of 5S and 45S ribosomal DNA and other repetitive elements. In the present work, presence of B chromosome(s) was confirmed through FISH on root tip and pollen mother cells. Several experiments were done to determine the transmission of B chromosome throug...

BACKGROUND Degradation of the mitotic cyclins is a hallmark of the exit from mitosis. Induction of stable versions of each of the three mitotic cyclins of Drosophila, cyclins A, B, and B3, arrests mitosis with different phenotypes. We tested a recent proposal that the destruction of the different cyclins guides progress through mitosis. RESULTS Real-time imaging revealed that arrest phenotype...

The chromosome numbers and karyotypes of five species the genus Bellevalia distributed in Turkey were analyzed. These taxa are B. anatolica Mathew & Özhatay, fominii Woronow, kurdistanica Feinbrun, rixii Wendelbo, turcica Pınar Eroğlu. Three them (B. anatolica, turcica) endemic Turkey. all studied determeined as 2n=2x=8. Haploid lengths varied from 57.78 µm fominii) to 68.17 anatolica) among sp...

Chromosome painting with DNA probes obtained from supernumerary (B) and sex chromosomes in three species of fish genus Characidium (C. gomesi, C. pterostictum and C. oiticicai) showed a close resemblance in repetitive DNA content between B and sex chromosomes in C. gomesi and C. pterostictum. This suggests an intraspecific origin for B chromosomes in these two species, probably deriving from se...
