Small RNA in plant meiosis and gametogenesis

Reproduction and Breeding, 2022
Small RNAs are short non-coding nucleotides and regulate various biological processes in eukaryotes. During past decades, numerous studies have demonstrated the biogenesis of small RNAs and their modes of action in regulating gene expression at the ...

Pre-meiotic H1.1 degradation is essential for Arabidopsis gametogenesis [PDF]

The EMBO Journal
Despite being evolutionary distant, plants and animals exhibit a shared phenomenon during the transition from somatic-to-reproductive cell fate marked by extensive structural and compositional changes in chromatin.

Exploring Reproductive Timing in Olive Tree: Male Meiosis and Anthesis Events [PDF]

Plants
The timing of male meiosis plays a pivotal role in ensuring successful pollination and may represent a critical window during which environmental stressors can significantly impact reproductive outcomes.

Extracellular vesicles in reproductive medicine: from “animal-led” to “plant-enabled” [PDF]

Frontiers in Cell and Developmental Biology
Extracellular vesicles (EVs) have emerged as pivotal mediators of intercellular communication in reproductive medicine, demonstrating considerable potential for both understanding and treating reproductive disorders. By precisely regulating key processes

ABAP1 Plays a Role in the Differentiation of Male and Female Gametes in Arabidopsis thaliana

Frontiers in Plant Science, 2021
The correct development of a diploid sporophyte body and a haploid gametophyte relies on a strict coordination between cell divisions in space and time. During plant reproduction, these divisions have to be temporally and spatially coordinated with cell ...

Retinoblastoma and its binding partner MSI1 control imprinting in Arabidopsis. [PDF]

PLoS Biology, 2008
Parental genomic imprinting causes preferential expression of one of the two parental alleles. In mammals, differential sex-dependent deposition of silencing DNA methylation marks during gametogenesis initiates a new cycle of imprinting. Parental genomic

Synergistic effects of dendrosomal nanocurcumin and oxaliplatin on oncogenic properties of ovarian cancer cell lines by down-expression of MMPs

Biological Research, 2023
Background Contrary to the advantageous anticancer activities of curcumin (Cur), limited bioavailability and solubility hindered its efficacy. Here, nontoxic dendrosomal nano carrier with Cur was used to overcome these problems.

cROStalk for Life: Uncovering ROS Signaling in Plants and Animal Systems, from Gametogenesis to Early Embryonic Development [PDF]

Genes, 2021
This review explores the role of reactive oxygen species (ROS)/Ca2+ in communication within reproductive structures in plants and animals. Many concepts have been described during the last years regarding how biosynthesis, generation products, antioxidant systems, and signal transduction involve ROS signaling, as well as its possible link with ...

Plant gametogenesis: conservation and contrasts in development [PDF]

Reproduction, 2004
Although the process of gamete formation in plants has many unique features, much has been learnt from the comparative analysis between plants and other eukaryotic systems. Plants have a number of factors that have made them desirable for the analysis of gamete development; these include late germline specification, the non-lethality of mutations ...

Epigenetic differentiation persists after male gametogenesis in natural populations of the perennial herb Helleborus foetidus (Ranunculaceae). [PDF]

PLoS ONE, 2013
Despite the importance of assessing the stability of epigenetic variation in non-model organisms living in real-world scenarios, no studies have been conducted on the transgenerational persistence of epigenetic structure in wild plant populations.
