Unraveling the origin of the Appalachian gametophyte, Vittaria appalachiana.
Pinson JB, Schuettpelz E. Pinson JB, et al. Am J Bot. 2016 Apr;103(4):668-76. doi: 10.3732/ajb.1500522. Epub 2016 Mar 31. Am J Bot. 2016. PMID: 27033317 Free article.
Notably, however, some species have perennial, vegetatively reproducing gametophytes. Vittaria appalachiana is one of just three species in which mature sporophytes are unknown. ...The origin of V. appalachiana, however, has long been a mystery, with most previous studies …

Population differentiation and countergradient variation throughout the geographic range in the fern gametophyte Vittaria appalachiana.
Chambers SM, Emery NC. Chambers SM, et al. Am J Bot. 2016 Jan;103(1):86-98. doi: 10.3732/ajb.1500077. Epub 2016 Jan 12. Am J Bot. 2016. PMID: 26758887 Free article.
Here, we evaluated the role of temperature in driving population differentiation in an asexual, obligate gametophyte fern species. METHODS: We reciprocally transplanted Vittaria appalachiana gametophytes among six populations that spanned the species' geographic range in t …

Gemmae: a role in sexual reproduction in the fern genus vittaria.
Emigh VD, Farrar DR. Emigh VD, et al. Science. 1977 Oct 21;198(4314):297-8. doi: 10.1126/science.198.4314.297. Science. 1977. PMID: 17770505
Gemmae are generally defined as vegetative propagules. In the shoestring ferns, Vittaria, gemmae grown in the presence of mature gametophyte plants or on medium containing gibberellic acid produce antheridia in lieu of vegetative growth. This suggests that antheridial diff …

Studies on ontogeny and reproductive behaviour of Lepisorus nudus (Hook.) Ching (Polypodiaceae).
Singh AP, Johari D, Khare PB. Singh AP, et al. J Plant Res. 2017 Mar;130(2):281-290. doi: 10.1007/s10265-016-0891-3. Epub 2016 Dec 24. J Plant Res. 2017. PMID: 28012124

A Remarkably Reduced Vascular Plant in the United States.
Wagner WH Jr, Sharp AJ. Wagner WH Jr, et al. Science. 1963 Dec 13;142(3598):1483-4. doi: 10.1126/science.142.3598.1483. Science. 1963. PMID: 17842342
Although bryophytic in appearance, the thallus is identified here for the first time as a greatly reduced variety of the vascular plant known as "shoestring fern," Vittaria lineata (L.) J. E. Smith, or a closely related species. The normally dominant sporophytic phase of t …

Differences in dehydration tolerance among populations of a gametophyte-only fern.
Chambers SM, Watkins JE Jr, Sessa EB. Chambers SM, et al. Am J Bot. 2017 Apr;104(4):598-607. doi: 10.3732/ajb.1600279. Epub 2017 Apr 11. Am J Bot. 2017. PMID: 28400414 Free article.
Additionally, if these historical conditions also prevented gene flow among populations, these populations may be differentiated with respect to one another and their contemporary environmental conditions. For the fern, Vittaria appalachiana, one theory is that historical …

Observations of the spore, gametophyte and young sporophyte of Pteridium caudatum (L.) Maxon using scanning electron microscopy.
Ramírez-Trejo Mdel R, Pérez-García B, Mendoza-Ruiz A, Valdez-Avila R, Espinosa-Matías S. Ramírez-Trejo Mdel R, et al. Micron. 2013 Feb;45:37-44. doi: 10.1016/j.micron.2012.10.011. Epub 2012 Oct 30. Micron. 2013. PMID: 23176817
Spores are trilete and germination takes place on the second day after sowing; germination is of the Vittaria-type. Adiantum-type prothallial development was observed. ...

[Prothallia in nine species of Callipteris and its comparison with other genera of the Woodsiaceae family].
