Why did heterospory evolve?
Petersen KB, Burd M. Petersen KB, et al. Biol Rev Camb Philos Soc. 2017 Aug;92(3):1739-1754. doi: 10.1111/brv.12304. Epub 2016 Oct 11. Biol Rev Camb Philos Soc. 2017. PMID: 27730728 Review.
Its role as a precursor to the evolution of seeds has received much attention, but this is an evolutionary consequence of heterospory that cannot explain the transition from homospory to heterospory (and the lack of evolutionary reversal from heterospory to h …

The adaptive value of heterospory: Evidence from Selaginella.
Petersen KB, Burd M. Petersen KB, et al. Evolution. 2018 May;72(5):1080-1091. doi: 10.1111/evo.13484. Epub 2018 Apr 24. Evolution. 2018. PMID: 29645092
Heterospory was a pivotal evolutionary innovation for land plants, but it has never been clear why it evolved. ...These results support previous theoretical arguments that heterospory was originally an adaptation to the increasing height and density of Devonian vege …

Key innovations in transition from homospory to heterospory.
Wang X, Bai SN. Wang X, et al. Plant Signal Behav. 2019;14(6):1596010. doi: 10.1080/15592324.2019.1596010. Epub 2019 Mar 20. Plant Signal Behav. 2019. PMID: 30892985 Free PMC article.
Heterospory (i.e. dimorphic spores) is a long-lasting topic discussed in plant biology. It is observed in many of ferns, fern allies, and seed plants. The rise of heterospory and the mechanisms underlying its success in plant evolution are not clearly elucidated. .. …

Reproduction Multitasking: The Male Gametophyte.
Hafidh S, Honys D. Hafidh S, et al. Annu Rev Plant Biol. 2021 Jun 17;72:581-614. doi: 10.1146/annurev-arplant-080620-021907. Epub 2021 Apr 26. Annu Rev Plant Biol. 2021. PMID: 33900787 Review.
Seed Evolution, A 'Simpler' Story.
Magnani E. Magnani E. Trends Plant Sci. 2018 Aug;23(8):654-656. doi: 10.1016/j.tplants.2018.06.002. Epub 2018 Jun 27. Trends Plant Sci. 2018. PMID: 29960816 Review.
Why Do Heterosporous Plants Have So Few Chromosomes?
Kinosian SP, Rowe CA, Wolf PG. Kinosian SP, et al. Front Plant Sci. 2022 Feb 16;13:807302. doi: 10.3389/fpls.2022.807302. eCollection 2022. Front Plant Sci. 2022. PMID: 35251082 Free PMC article. Review.
Many studies have investigated why homosporous plants have so many chromosomes. However, homospory is the ancestral condition from which heterospory has been derived several times. Following this phylogenetic perspective, a more appropriate question to ask is why heterospo …

Cyst-Theca Relationship and Phylogenetic Position of Impagidinium caspienense Incubated from Caspian Sea Surface Sediments: Relation to Gonyaulax baltica and Evidence for Heterospory within Gonyaulacoid Dinoflagellates.
Mertens KN, Takano Y, Gu H, Bagheri S, Pospelova V, Pieńkowski AJ, Leroy SAG, Matsuoka K. Mertens KN, et al. J Eukaryot Microbiol. 2017 Nov;64(6):829-842. doi: 10.1111/jeu.12417. Epub 2017 May 11. J Eukaryot Microbiol. 2017. PMID: 28397389
The ability of this species to belong to two types of cyst-based genera (spiniferate and impagidinioid) suggests that environmental (particularly salinity) and not genetic factors explain the formation of both morphotypes by G. baltica, which provides evidence for heterospory …

Insights into the evolutionary history and widespread occurrence of antheridiogen systems in ferns.
Hornych O, Testo WL, Sessa EB, Watkins JE Jr, Campany CE, Pittermann J, Ekrt L. Hornych O, et al. New Phytol. 2021 Jan;229(1):607-619. doi: 10.1111/nph.16836. Epub 2020 Aug 25. New Phytol. 2021. PMID: 32740926 Free PMC article. Review.
The antheridiogen system likely evolved multiple times and provides homosporous ferns with the benefits often associated with heterospory, such as increased rates of outcrossing. Despite expectations, antheridiogens may be beneficial to polyploids and apomicts....

Archaeopteris from the Upper Famennian of Belgium: heterospory, nomenclature, and palaeobiogeography.
Fairon-Demaret M, Leponce I, Streel M. Fairon-Demaret M, et al. Rev Palaeobot Palynol. 2001 May;115(1-2):79-97. doi: 10.1016/s0034-6667(01)00051-3. Rev Palaeobot Palynol. 2001. PMID: 11425349 Free article.
Vegetative leaves occur both proximal and distal to the fertile leaves. Heterospory is demonstrated with miospores belonging to the Geminospora-Aneurospora complex and macrospores most probably to Contagisporites genus. ...
