Speciation with gene flow between two Neotropical sympatric species (Pitcairnia spp.: Bromeliaceae).
Tavares MM, Ferro M, Leal BSS, Palma-Silva C. Tavares MM, et al. Ecol Evol. 2022 Apr 29;12(5):e8834. doi: 10.1002/ece3.8834. eCollection 2022 May. Ecol Evol. 2022. PMID: 35509614 Free PMC article.
Here, we investigated genomic differentiation between hybridizing Neotropical species Pitcairnia staminea (G. Lodd.) and P. albiflos (Herb.). Using thousands of SNPs genotyped through RAD-seq, we estimate effective population sizes, interspecific gene flow, as well as time …

Genetic diversity and karyotype of Pitcairnia azouryi: an endangered species of Bromeliaceae endemic to Atlantic Forest inselbergs.
Manhães VDC, de Miranda FD, Clarindo WR, Carrijo TT. Manhães VDC, et al. Mol Biol Rep. 2020 Jan;47(1):179-189. doi: 10.1007/s11033-019-05118-6. Epub 2019 Oct 5. Mol Biol Rep. 2020. PMID: 31587186
This, in turn, can result in the loss of natural populations due to homozygosis, or changes in ploidy that may lead to reproductive isolation. The genetic diversity of five natural populations of Pitcairnia azouryi was measured using nine microsatellite markers transferred …

Origin and Function of Amino Acids in Nectar and Nectaries of Pitcairnia Species with Particular Emphasis on Alanine and Glutamine.
Göttlinger T, Lohaus G. Göttlinger T, et al. Plants (Basel). 2023 Dec 20;13(1):23. doi: 10.3390/plants13010023. Plants (Basel). 2023. PMID: 38202331 Free PMC article.
Therefore, the amino acid, sugar, and inorganic ion concentrations, as well as the activity of alanine aminotransferase (AlaAT) and glutamine synthetase (GS) in nectar, nectaries, and leaves were analyzed in 30 Pitcairnia species. These data were compared with various flor …

Sympatric bromeliad species (Pitcairnia spp.) facilitate tests of mechanisms involved in species cohesion and reproductive isolation in Neotropical inselbergs.
Palma-Silva C, Wendt T, Pinheiro F, Barbará T, Fay MF, Cozzolino S, Lexer C. Palma-Silva C, et al. Mol Ecol. 2011 Aug;20(15):3185-201. doi: 10.1111/j.1365-294X.2011.05143.x. Epub 2011 Jun 15. Mol Ecol. 2011. PMID: 21672064
Particularly scarce (and thus of particular interest) are molecular genetic data on recently radiated, naturally hybridizing species in strongly structured and species-rich environments. Here, we studied four sympatric plant species (Pitcairnia spp.; Bromeliaceae) adapted …

Mechanisms of desiccation tolerance in the bromeliad Pitcairnia burchellii Mez: biochemical adjustments and structural changes.
Vieira EA, Silva KR, Oriani A, Moro CF, Braga MR. Vieira EA, et al. Plant Physiol Biochem. 2017 Dec;121:21-30. doi: 10.1016/j.plaphy.2017.10.002. Epub 2017 Oct 10. Plant Physiol Biochem. 2017. PMID: 29080424
Vegetation in this environment is exposed to an extended dry season and extreme conditions due to rocky soils and high sun exposure. In this study, we demonstrated that Pitcairnia burchellii, a bromeliad from rocky outcrops, tolerates intense desiccation for about 90 days …

Transcriptome data from silica-preserved leaf tissue reveal gene flow patterns in a Caribbean bromeliad.
Ruiz-Vargas N, Ramanauskas K, Tyszka AS, Bretz EC, Yeo MTS, Mason-Gamer RJ, Walker JF. Ruiz-Vargas N, et al. Ann Bot. 2024 Apr 10;133(3):459-472. doi: 10.1093/aob/mcae002. Ann Bot. 2024. PMID: 38181407 Free PMC article.
Using these transcriptomes, we explore the evolutionary relationships of the genus Pitcairnia (Bromeliaceae) in the Dominican Republic and infer barriers to gene flow. ...The genetic diversity among Pitcairnia populations does not warrant classification as separate …
