Circumnutation in the growth of Chara rhizoids

Acta Societatis Botanicorum Poloniae, 2014
The chromosome numbers of 24 species of Achillea L. were determined, among them 4 for the first time (A. chamaemelifolia, A. sulphurea, A. teretifolia, A. vermicularis). A tetraploid form of A. lingulata was found for the first time. The occurrence of di-

Genome size stability despite high chromosome number variation in Carex gr. laevigata.

American-Eurasian journal of botany, 2015
PREMISE OF THE STUDY In organisms with holocentric chromosomes like Carex species, chromosome number evolution has been hypothesized to be a result of fission, fusion, and/or translocation events.

Role of the Number of Microtubules in Chromosome Segregation during Cell Division [PDF]

PLoS ONE, 2015
Faithful segregation of genetic material during cell division requires alignment of chromosomes between two spindle poles and attachment of their kinetochores to each of the poles.

Autophagy gene haploinsufficiency drives chromosome instability, increases migration, and promotes early ovarian tumors. [PDF]

, 2020
Autophagy, particularly with BECN1, has paradoxically been highlighted as tumor promoting in Ras-driven cancers, but potentially tumor suppressing in breast and ovarian cancers.

Comparative chromosome painting discloses homologous Segments in distantly related mammals [PDF]

, 1994
Comparative chromosome painting, termed ZOO-FISH, using DNA libraries from flow sorted human chromosomes 1,16,17 and X, and mouse chromosome 11 discloses the presence of syntenic groups in distantly related mammalian Orders ranging from primates (Homo

Cyto-systematical study of the genus Senna Mill. in diverse geographical locations of Uttar Pradesh

Electronic Journal of Plant Breeding, 2021
Senna Mill. is one of the most typical genus of caesalpiniodeae, with wide geographical distribution and diversification. The research work was planned with an objective of taxonomical characterization and assessment of the meiotic behaviour of wild ...

CHROMOSOME NUMBERS IN BROMELIACEAE

American Journal of Botany, 1989
Eighty‐three chromosome counts are reported for 72 taxa of the Bromeliaceae. Fifty‐eight of these counts are the first known chromosome number reports for their respective taxa. A model of chromosomal evolution in the Bromeliaceae (n = 25) is presented. The model is parsimonious and consistent with existing data on meiotic chromosome numbers within the

ChromEvol: assessing the pattern of chromosome number evolution and the inference of polyploidy along a phylogeny.

Molecular biology and evolution, 2014
We announce the release of chromEvol version 2.0, a software tool for inferring the pattern of chromosome number change along a phylogeny. The software facilitates the inference of the expected number of polyploidy and dysploidy transitions along each ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

FEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Errors in chromosome segregation during oogenesis and early embryogenesis [PDF]

, 2010
Errors in chromosome segregation occurring during human oogenesis and early embryogenesis are very common. Meiotic chromosome development during oogenesis is subdivided into three distinct phases.
