Timeless inner beauty…

This study of the fossilised stem of a royal fern in Lahar deposits from Korsaröd in Scania includes cellular details that are ‘exquisitely preserved’.

When trying to appreciate something, it’s often remarked that it is the ‘inner beauty’ that’s important. In which case the plant cell biologists who probe the details within cells (and often illuminate them in all their glorious pin-point precision and fluorescent beauty with immunofluorescent techniques*) must not only, as scientists, be seekers of truth (for is it not writ, in scientia veritas?)  but also be true searchers after beauty. And if something’s really beautiful/true then it has a quality that transcends normal, mortal values and should be permanent. Is that correct? Well, the palaeopteridophytological work of Benjamin Bomfleur et al. may just be the definitive proof of that notion of transcendental permanence. Using language unusual for a serious, sober, scientific article, they describe the fossilised stem of a royal fern (family: Osmundaceae) in Lahar deposits (of putative Early Jurassic – Pliensbachian – date; 189.6–183 million years ago) from Korsaröd in Scania (southern Sweden) as having cellular details that are ‘exquisitely preserved’. Amongst the sub-cellular features discernible are parenchyma cells in the pith and cortex that show preserved membrane-bound cytoplasm, cytosol granules and putative amyloplasts (starch-bearing bodies). Furthermore, most cells contain interphase nuclei with conspicuous nucleoli! And – even more remarkably? – Supplementary Fig. S6 shows detail that is interpreted as signs of necrosis and programmed cell death(!). Whilst more importance is attached by the authors to the fact that the genome size of these reputed ‘living fossils’ has remained unchanged over at least 180 million years (and is understandably viewed as a ‘paramount example of evolutionary stasis’), the degree of internal preservation of cell contents is so good (see Figs S4 and S6 in the paper’s supplementary material!) I’m sure many extant workers could only hope to emulate such faithful preservation in their current work! So, not only is a thing of beauty a joy, it is a joy… forever (or 180 million years at least – long enough for you?). Somebody should write a poem about that!

I am a botanist and former Senior Lecturer in Botany at Bath Spa University (Bath, near Bristol, UK). As News Editor for the Annals of Botany I contributed the monthly Plant Cuttings column to that august international botanical organ - and to Botany One - for almost 10 years. I am now a freelance plant science communicator and Visiting Research Fellow at Bath Spa University. I continue to share my Cuttingsesque items - and appraisals of books with a plant focus - with a plant-curious audience. In that guise my main goal is to inform (hopefully, in an educational, and entertaining way) others about plants and plant-people interactions, and thereby improve humankind's botanical literacy. Happy to be contacted to discuss potential writing - or talking - projects and opportunities.
