Chromatin dynamics during plant sexual reproduction

Frontiers in Plant Science, 2014
Plants have the remarkable ability to establish new cell fates throughout their life cycle, by contrast to most animals that define all cell lineages during embryogenesis.

Characterization of genes encoding poly(A) polymerases in plants: evidence for duplication and functional specialization. [PDF]

PLoS ONE, 2009
BACKGROUND:Poly(A) polymerase is a key enzyme in the machinery that mediates mRNA 3' end formation in eukaryotes. In plants, poly(A) polymerases are encoded by modest gene families.

Repetitive DNA as marker for the study of male gametogenesis in higher plants. I. Analysis in some species ofTradescantiaandNarcissus [PDF]

Caryologia, 1997
SUMMARYThe use of heterochromatic regions, containing moderately repetitive DNA as markers, has allowed to follow the course of development of the generative and vegetative nuclei in the pollen grains of some species of Tradescantia and Narcissus.

A Novel Imprinted Gene NUWA Controls Mitochondrial Function in Early Seed Development in Arabidopsis. [PDF]

PLoS Genetics, 2017
Imprinted genes display biased expression of paternal and maternal alleles and are only found in mammals and flowering plants. Compared to several hundred imprinted genes that are functionally characterized in mammals, very few imprinted genes were ...

Male gametogenesis in flowering plants

Frontiers in Sustainable Food Systems
The life cycles of plants are characterized by significant alternations between the diploid sporophytic and the haploid gametophytic generations. Meiosis and fertilization are the prerequisites for achieving the alternation of generations. Diploid sporophytes undergo meiosis to produce haploid gametes, and male–female gametes fuse (double fertilization)

CHCHD10 Mitigates Alzheimer's Disease‐Related Phenotypes in Association With Epigenetic Remodeling in Directly Reprogrammed Neurons

Advanced Science, EarlyView.
CHCHD10 loss in Alzheimer's disease is associated with mitochondrial dysfunction, epigenomic disruption, and tau pathology. Restoration of CHCHD10 shifts DNA methylation toward a non‐disease state and reduces tau and amyloid pathology, with KATNAL2 acting as a downstream effector.

eEF1G Orchestrates Translation to Ensure Meiotic Progression in Transcriptionally Quiescent Spermatocytes

Advanced Science, EarlyView.
eEF1G supports translation elongation of meiotic mRNAs in transcriptionally quiescent leptotene and zygotene spermatocytes. Its depletion in germ cells causes meiotic arrest at the zygotene stage, with defective homologous synapsis and unstable recombination intermediates.

Genetic Loci Governing Androgenic Capacity in Perennial Ryegrass (Lolium perenne L.)

G3: Genes, Genomes, Genetics, 2018
Immature pollen can be induced to switch developmental pathways from gametogenesis to embryogenesis and subsequently regenerate into homozygous, diploid plants.

NOF1 encodes an Arabidopsis protein involved in the control of rRNA expression. [PDF]

PLoS ONE, 2010
The control of ribosomal RNA biogenesis is essential for the regulation of protein synthesis in eukaryotic cells. Here, we report the characterization of NOF1 that encodes a putative nucleolar protein involved in the control of rRNA expression in ...

The E3 Ubiquitin Ligase RLIM Safeguards Oligodendrocyte Development and Myelination by Targeting SLC7A11 for Polyubiquitination to Regulate Ferroptotic Resistance

Advanced Science, EarlyView.
RLIM‐mediated SLC7A11 polyubiquitination is required for SPTBN2‐mediated trafficking and membrane localization of SLC7A11, which enables oligodendrocyte precursor cells to be resistant to ferroptosis and safeguards oligodendrocyte lineage progression and thus myelination.
