Evolutionary mobility and genetic dynamics of MORFFO genes: shuttling among ancient plant lineages
New Phytologist, Volume 250, Issue 2, Page 1248-1264, April 2026.Summary Plastid genomes (plastomes) of land plants are characterized by their architectural and genic content stability. However, fern plastomes exhibit unexpected dynamism, characterized by the presence of mobile protein‐coding genes (CDS) – Mobile Open Reading Frames in Fern Organelles (MORFFOs). We investigate the evolutionary dynamics of MORFFOs in

The Structure of Petioles in Pteris (Pteridaceae)
American Fern Journal, 2012 Abstract We studied the petiole structure of twelve American species of Pteris: P. ciliaris, P. cretica, P. deflexa, P. denticulata, P. ensiformis, P. exigua, P. inermis, P. multifida, P. mutilata, P. quadriaurita, P. tristicula and P. vittata, using both light and scanning electron microscopy. We found that petioles are characterized externally by the

Plants and Insect Eggs: First Report of a Katydid Using a Fern as Host for Oviposition
New Zealand Journal of Botany, Volume 64, Issue 1, March 2026.Ferns are the second most diverse lineage of vascular plants worldwide and are particularly abundant in tropical forests. However, the ecological significance of such remarkable diversity has been often underestimated. In this article, we report for the first time the observation of ferns, specifically Polytaenium cajenense (Desv.) Benedict ...

Adaptive Significance of Nickel Hyperaccumulation by Plants
Ecological Research, Volume 41, Issue 2, March 2026.Metal hyperaccumulation may enhance plant fitness through multiple, non‐exclusive mechanisms, including elemental defense against herbivores and pathogens, altered pollinator interactions, and increased reproductive performance in metal‐rich soils. Metals may also affect plant–plant interactions via elemental allelopathy and improve stress tolerance ...
