Selection on meiosis genes in diploid and tetraploid Arabidopsis arenosa.
Molecular biology and evolution, 2015 Meiotic chromosome segregation is critical for fertility across eukaryotes, and core meiotic processes are well conserved even between kingdoms. Nevertheless, recent work in animals has shown that at least some meiosis genes are highly diverse or ...

Cytoskeleton, EarlyView.ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Elevated Mutation Rate during Meiosis in Saccharomyces cerevisiae
PLoS Genetics, 2015 Mutations accumulate during all stages of growth, but only germ line mutations contribute to evolution. While meiosis contributes to evolution by reassortment of parental alleles, we show here that the process itself is inherently mutagenic.

Cytoskeleton, EarlyView.ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

BMC Genomics, 2015 Sexual reproduction is an obligate phase in the life cycle of most eukaryotes. Meiosis varies among organisms, which is reflected by the variability of the gene set associated to the process.

Heterochromatin in plant meiosis
NucleusHeterochromatin is an organizational property of eukaryotic chromosomes, characterized by extensive DNA and histone modifications, that is associated with the silencing of transposable elements and repetitive sequences. Maintaining heterochromatin is crucial for ensuring genomic integrity and stability during the cell cycle.

Pre‐oviposition development of the brown anole (Anolis sagrei)
Developmental Dynamics, EarlyView.Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

The Phosphatase Dusp7 Drives Meiotic Resumption and Chromosome Alignment in Mouse Oocytes
Cell Reports, 2016 Summary: Mammalian oocytes are stored in the ovary, where they are arrested in prophase for prolonged periods. The mechanisms that abrogate the prophase arrest in mammalian oocytes and reinitiate meiosis are not well understood.

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby
Developmental Dynamics, EarlyView.Abstract Background RSPO1 and FOXL2 are female sex‐determining genes involved in the differentiation and organization of the ovary in some eutherian mammals. Mutations or loss of function of these genes are associated with partial to full sex reversal in mice, humans, and goats.
