The Rim15-endosulfine-PP2ACdc55 signalling module regulates entry into gametogenesis and quiescence via distinct mechanisms in budding yeast.

open access: yesPLoS Genetics, 2014
Quiescence and gametogenesis represent two distinct survival strategies in response to nutrient starvation in budding yeast. Precisely how environmental signals are sensed by yeast cells to trigger quiescence and gametogenesis is not fully understood.

Genetic and karyotype divergence between parents affect clonality and sterility in hybrids

open access: yeseLife, 2023
Asexual reproduction can be triggered by interspecific hybridization, but its emergence is supposedly rare, relying on exceptional combinations of suitable genomes.

Ligula intestinalis (Cestoda: Pseudophyllidea): an ideal fish-metazoan parasite model? [PDF]

open access: yes, 2010
Since its use as a model to study metazoan parasite culture and in vitro development, the plerocercoid of the tapeworm, Ligula intestinalis, has served as a useful scientific tool to study a range of biological factors, particularly within its fish ...

Beyond tradition: exploring the non-canonical functions of telomeres in meiosis

open access: yesFrontiers in Cell and Developmental Biology, 2023
The telomere bouquet is a specific chromosomal configuration that forms during meiosis at the zygotene stage, when telomeres cluster together at the nuclear envelope.

The malaria parasite cyclic GMP-dependent protein kinase plays a central role in blood-stage schizogony [PDF]

open access: yes, 2010
A role for the Plasmodium falciparum cyclic GMP (cGMP)-dependent protein kinase (PfPKG) in gametogenesis in the malaria parasite was elucidated previously. In the present study we examined the role of PfPKG in the asexual blood-stage of the parasite life

Recent Research Advances in Mitosis during Mammalian Gametogenesis

open access: yesCells, 2019
Mitosis is a highly sophisticated and well-regulated process during the development and differentiation of mammalian gametogenesis. The regulation of mitosis plays an essential role in keeping the formulation in oogenesis and gametogenesis.

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]

open access: yes, 2009
Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

De novo sequencing of the Hypericum perforatum L. flower transcriptome to identify potential genes that are related to plant reproduction sensu lato [PDF]

open access: yes, 2015
Background: St. John's wort (Hypericum perforatum L.) is a medicinal plant that produces important metabolites with antidepressant and anticancer activities.

Structure and non-essential function of glycerol kinase in Plasmodium falciparum blood stages [PDF]

open access: yes, 2009
Malaria pathology is caused by multiplication of asexual parasites within erythrocytes, whereas mosquito transmission of malaria is mediated by sexual precursor cells (gametocytes).

The effect of vitrified ovarian tissue autotransplantation encapsulated with hyaluronic acid hydrogen on VEGF, CD31 and CD34 gene expression in rat

open access: yesFiyz̤, 2021
Background: One of the problems after cryopreservation and ovarian tissue transplantation is ischemia followed by follicles mortality. In the present study, hyaluronic acid hydrogel was used to improve angiogenesis in vitrified ovarian tissue ...
