Cold-induced male meiotic restitution in Arabidopsis thaliana is not mediated by GA-DELLA signaling [PDF]
, 2018 Short periods of cold stress induce male meiotic restitution and diploid pollen formation in Arabidopsis thaliana by specifically interfering with male meiotic cytokinesis.

Frontiers in Plant Science, 2018 Meiosis, the type of cell division that halves the chromosome number, shows a considerable degree of diversity among species. Unraveling molecular mechanisms of the meiotic machinery has been mainly based on meiotic mutants, where the effects of a change

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.

The meiotic behavior of an inversion in Caenorhabditis elegans. [PDF]
Genetics, 1992 Abstract The rearrangement hIn1(I) was isolated as a crossover suppressor for the right end of linkage group (LG) I. By inducing genetic markers on this crossover suppressor and establishing the gene order in the homozygote, hIn1(I) was demonstrated to be the first genetically proven inversion in Caenorhabditis elegans.

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

Palynology and meiotic behavior of Genipa americana L., a species native to the Amazon
Bioscience Journal, 2023 Genipa americana L., commonly known as genipap, belongs to the Rubiaceae family. This study aimed to describe the pollen morphology of the species, evaluate its meiotic behavior and pollen viability, and provide information to help the maintenance and ...

Influence of M-phase chromatin on the anisotropy of microtubule asters [PDF]
, 1996 In many eukaryotic cells going through M-phase, a bipolar spindle is formed by microtubules nucleated from centrosomes. These microtubules, in addition to being "captured" by kinetochores, may be stabilized by chromatin in two different ways: short-range

Meiosis-specific loading of the centromere-specific histone CENH3 in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2011 Centromere behavior is specialized in meiosis I, so that sister chromatids of homologous chromosomes are pulled toward the same side of the spindle (through kinetochore mono-orientation) and chromosome number is reduced.

Chromosome segregation in plant meiosis [PDF]
, 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

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy [PDF]
, 2020 In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes.
