Article Synopsis
- Natural hybridization is important for biodiversity, especially in ferns, but there's still a lack of understanding of how it works in these plants.
- The study uses advanced genetic techniques to analyze the hybridization origins of the fern species M. matthewii and its potential parental species, looking at nuclear and chloroplast genetic markers.
- Results indicate that M. matthewii shows a mixed genetic profile from its parent species, with significant evidence of gene flow, suggesting it is a hybrid that does not follow a 1:1 parentage ratio and exhibits complex hybridization dynamics.
Understanding how natural hybridization and polyploidizations originate in plants requires identifying potential diploid ancestors. However, cryptic plant species are widespread, particularly in (Pteridaceae). Identifying cryptic species with different polyploidy levels is a challenge because spp.

By applying fluorescence imaging in intact tissues using dyes and confocal microscopy, this study aimed to reconstruct the key steps during the development of sporangia. Special emphasis was taken on the cell wall structures of tapetum and spore mother cells that have been challenged by microscopical documentation in the past.

Ultrastructural observations indicate a separation cavity is first formed above the egg during oogenesis with a pore region persistently connecting the egg and the ventral canal cell.
