“…Through comparison with previous findings in other fern species (Banks, 1999;Banks et al, 1993;Bartz & Gola, 2018;Conway & Di Stilio, 2020;Takahashi et al, 2009Takahashi et al, , 2012Takahashi et al, , 2015Wu et al, 2021), our results suggest both conserved and unique patterns of cell division that drive meristem development in gametophytes. Considering the diversity of ferns and fern allies (Christenhusz & Byng, 2016;PPG, I., 2016;Sessa, 2018), the quantitative imaging platform that we have established will be valuable to further explore meristem evolution across different fern taxa and to comprehensively reveal cell behaviors in fern gametophytes in the future.…”

SUMMARY In contrast to seed plants, the gametophytes of seed‐free plants develop pluripotent meristems, which promote and sustain their independent growth and development. To date, the cellular basis of meristem development in gametophytes of seed‐free ferns remains largely unknown. In this study, we used Woodsia obtusa, the blunt‐lobe cliff fern, to quantitatively determine cell growth dynamics in two different types of apical meristems – the apical initial centered meristem and the multicellular apical meristem in gametophytes. Through confocal time‐lapse live imaging and computational image analysis and quantification, we determined unique patterns of cell division and growth that sustain or terminate apical initials, dictate the transition from apical initials to multicellular apical meristems, and drive proliferation of apical meristems in ferns. Quantitative results showed that small cells correlated to active cell division in fern gametophytes. The marginal cells of multicellular apical meristems in fern gametophytes undergo division in both anticlinal and periclinal orientations, not only increasing cell numbers but also playing a dominant role in increasing cell layers during gametophyte development. All these findings provide insights into the function and regulation of meristems in gametophytes of seed‐free vascular plants, suggesting both conserved and diversified mechanisms underlying meristem cell proliferation across land plants.

The area of phytosynthesized nanomaterials is rapidly developing, with numerous studies being published yearly. The use of plant extracts is an alternative method to reduce the toxic potential of the nanomaterials and the interest in obtaining phytosynthesized nanoparticles is usually directed towards accessible and common plant species, ferns not being explored to their real potential in this field. The developed nanoparticles could benefit from their superior antimicrobial and antioxidant properties (compared with the nanoparticles obtained by other routes), thus proposing an important alternative against health care-associated and drug-resistant infections, as well as in other types of applications. The present review aims to summarize the explored application of ferns in nanotechnology and related areas, as well as the current bottlenecks and future perspectives, as emerging from the literature data.

“…Previous studies demonstrated that the gametophytes of many examined ferns either lacked persistent ACs or maintained only an active AC for a limited time throughout the whole gametophyte development (Banks et al, 1993;Bartz & Gola, 2018;Conway & Di Stilio, 2020;Geng et al, 2022;Imaichi, 2013;Takahashi et al, 2009;Wu et al, 2021;. In gametophytes of the widely studied fern C. richardii (Pteridaceae) (Banks, 1999;Bui et al, 2015;Chatterjee & Roux, 2000;Cooke et al, 1995;Eberle et al, 1995;Geng et al, 2021a;Geng et al, 2022;Hickok et al, 1995;Marchant et al, 2019;Plackett et al, 2015;2018), the AC is only transiently present in a gametophyte after germination, and it quickly disappears as the prothallus expands (Banks, 1999;Bartz & Gola, 2018). Prothallus development in Ceratopteris is mainly driven by the multicellular meristem initiated from the lateral marginal layer (Banks, 1999;Bartz & Gola, 2018;Conway & Di Stilio, 2020), and this multicellular meristem does not contain any morphologically distinct ACs (Banks, 1999;Geng et al, 2022).…”

Quantitative live-imaging reveals the dynamics of apical cells during gametophyte development in ferns

Meristems in land plants share conserved functions but develop highly variable structures. Meristems in seed-free plants, including ferns, usually contain one or a few pyramid-/wedge-shaped apical cells (ACs) as initials, which are lacking in seed plants. It remained unclear how ACs promote cell proliferation in fern gametophytes and whether any persistent AC exists to sustain fern gametophyte development continuously. Here, we uncovered previously undefined ACs maintained even at late developmental stages in fern gametophytes. Through quantitative live-imaging, we determined division patterns and growth dynamics that maintain the persistent AC in Sphenomeris chinensis, a representative fern. The AC and its immediate progenies form a conserved cell packet, driving cell proliferation and prothallus expansion. At the apical centre of gametophytes, the AC and its adjacent progenies display small dimensions resulting from active cell division instead of reduced cell expansion. These findings provide insight into diversified meristem development in land plants.
