Cytological analysis of MRE11 protein during early meiotic prophase I in Arabidopsis and tomato [PDF]

open access: yes, 2008
Early recombination nodules (ENs) are multiprotein complexes that are thought to be involved in synapsis and recombination, but little is known about their components or how they may be involved in these events. In this study, we describe the cytological

Cytogenetic study and pollen viability of four populations of Trigonella [PDF]

open access: yesJournal of Cell and Molecular Research, 2011
In the present paper, the cytogenetic study including meiotic chromosome number and behavior along with pollen viability were performed in 4 populations of Trigonella spruneriana Boiss. This is the first cytogenetic report of the taxon.

Chromosome segregation in plant meiosis [PDF]

open access: yes, 2014
Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

Meiotic behavior and karyotypic variation in Acledra (Pentatomidae, Heteroptera)

open access: yesGenetics and Molecular Research, 2010
Acledra comprises 15 taxonomically identified species, most of which are crop pests. This is the first cytogenetic study of species of this genus. Acledra kinbergii and A. modesta showed the modal number of the Pentatomidae (2n = 14 = 12 + XY), while A.

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

open access: yes, 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.

Intertwined Functions of Separase and Caspase in Cell Division and Programmed Cell Death. [PDF]

open access: yes, 2020
Timely sister chromatid separation, promoted by separase, is essential for faithful chromosome segregation. Separase is a member of the CD clan of cysteine proteases, which also includes the pro-apoptotic enzymes known as caspases.
