Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]

open access: yes, 2017
Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Plastids and mitochondria comportment in dividing meiocytes of Psilotum nudum

open access: yesActa Societatis Botanicorum Poloniae, 2014
In prophase I meiocyte plastids and mitochondria were situated at random. By telophase I plastids and mitochondria were aggregated in an equatorial plane.

Pistil transcriptome analysis to disclose genes and gene products related to aposporous apomixis in Hypericum perforatum L. [PDF]

open access: yes, 2017
Unlike sexual reproduction, apomixis encompasses a number of reproductive strategies,which permit maternal genome inheritance without genetic recombination and syngamy.

Evolution and expression of LEAFY genes in ferns and lycophytes

open access: yesEvoDevo, 2022
Background The LEAFY (LFY) transcription factors are present in algae and across land plants. The available expression and functional data of these genes in embryophytes suggest that LFY genes control a plethora of processes including the first zygotic ...

CENH3-GFP: a visual marker for gametophytic and somatic ploidy determination in Arabidopsis thaliana [PDF]

open access: yes, 2016
Background: The in vivo determination of the cell-specific chromosome number provides a valuable tool in several aspects of plant research. However, current techniques to determine the endosystemic ploidy level do not allow non-destructive, cell-specific

Exploring the Influence of Temperature on Aspects of the Reproductive Phenology of Temperate Seaweeds

open access: yesFrontiers in Marine Science, 2018
As plants on land, seaweeds are likely to be susceptible to temperature-mediated changes in phenology such as shifts in their reproductive timing.

The subunit of RNA N6-methyladenosine methyltransferase OsFIP regulates early degeneration of microspores in rice.

open access: yesPLoS Genetics, 2019
N6-Methyladenosine (m6A) RNA methylation plays important roles during development in different species. However, knowledge of m6A RNA methylation in monocots remains limited.

Cytological characterization and allelism testing of anther developmental mutants identified in a screen of maize male sterile lines. [PDF]

open access: yes, 2013
Proper regulation of anther differentiation is crucial for producing functional pollen, and defects in or absence of any anther cell type result in male sterility.
