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

SEXUAL STERILITY is Essential for Both Male and Female Gametogenesis in Tomato [PDF]
, 2017 Gametogenesis is a key step in the production of ovules or pollen in higher plants. The molecular aspects of gametogenesis are well characterized in the model plant Arabidopsis; however, little information is known in tomato, which is a model plant for ...

Nuclear Fusion in Yeast and Plant Reproduction
Plants, 2023 Nuclear fusion is essential for the sexual reproduction of various organisms, including plants, animals, and fungi. During the life cycle of flowering plants, nuclear fusion occurs three times: once during female gametogenesis and twice during double ...

Pistil transcriptome analysis to disclose genes and gene products related to aposporous apomixis in Hypericum perforatum L. [PDF]
, 2017 Unlike sexual reproduction, apomixis encompasses a number of reproductive strategies,which permit maternal genome inheritance without genetic recombination and syngamy.

Evidence for a role of Arabidopsis CDT1 proteins in gametophyte development and maintenance of genome integrity [PDF]
, 2012 Meristems retain the ability to divide throughout the life cycle of plants, which can last for over 1000 years in some species. Furthermore, the germline is not laid down early during embryogenesis but originates from the meristematic cells relatively ...

Plasmodium Condensin Core Subunits SMC2/SMC4 Mediate Atypical Mitosis and Are Essential for Parasite Proliferation and Transmission [PDF]
, 2020 Condensin is a multi-subunit protein complex regulating chromosome condensation and segregation during cell division. In Plasmodium spp., the causative agent of malaria, cell division is atypical and the role of condensin is unclear.

The nucleolar organizer (NOR) and fibrillar centers during plant gametogenesis
Journal of Ultrastructure Research, 1983 The ultrastructure and morphometric features of nucleolar fibrillar centers have been studied in three different plant species over a long period of gametogenesis, extending from premeiosis to after the first postmeiotic mitosis, with respect to variations in nucleolar activity which occur throughout this process.

Cold-induced male meiotic restitution in Arabidopsis thaliana is not mediated by GA-DELLA signaling [PDF]
, 2018 Short periods of cold stress induce male meiotic restitution and diploid pollen formation in Arabidopsis thaliana by specifically interfering with male meiotic cytokinesis.

Epigenetic modifications during angiosperm gametogenesis
Frontiers in Plant Science, 2012 Angiosperms do not contain a distinct germline, but rather develop gametes from gametophyte initials that undergo cell division. These gametes contain cells that give rise to an endosperm and the embryo.
