Complete chloroplast genome of Sphaeropteris brunoniana (Cyatheaceae) [PDF]
Mitochondrial DNA. Part B. Resources, 2020 Illumina sequencing was employed to determine the complete chloroplast (cp) genome sequence of Sphaeropteris brunoniana (S. brunoniana), which is a relict fern. The cp genome of S. brunoniana is indeed a circular DNA molecule with 156,659 bp. It includes

Palynological analysis of Sphaeropteris gardneri (Cyatheaceae, Pteridophyta) [PDF]
Anais Da Academia Brasileira De Ciencias, 2010 The spore morphology and wall ultrastructure of Sphaeropteris gardneri (Hook.) R.M. Tryon from Brazil were analyzed with LM, SEM and TEM. The spores are trilete with an ornamentation formed of short low ridges with spines in their margins.

Non-chlorophyllous and crypto-chlorophyllous fern spores differ in their mobilisation of fatty acids during priming. [PDF]
Physiol Plant, 2023 Abstract During fern spore germination, lipid hydrolysis primarily provides the energy to activate their metabolism. In this research, fatty acids (linoleic, oleic, palmitic and stearic) were quantified in the spores exposed or not to priming (hydration–dehydration treatments).

Fern Spores—“Ready-to-Use” Standards for Plant Genome Size Estimation Using a Flow Cytometric Approach [PDF]
Plants, 2022 Spores and pollen of plants were used as flow cytometric materials to efficiently infer genome sizes. Given this advantage, they hold great potential for various flow cytometric applications, particularly as plant genome size standards.
