Lectotypification of Selaginella decomposita (Selaginellaceae)

Phytotaxa, 2016
During the preparation of the taxonomic treatment of Selaginellaceae from Brazil (Góes-Neto et al. in prep.) we discovered that various Neotropical – particularly Brazilian – species were poorly typified. Of the species assessed, we verified that ca. 20 species already have a lectotype designated inadvertently (see McNeil et al. 2012, Art.

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

New Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Weak link or strong foundation? Vulnerability of fine root networks and stems to xylem embolism

New Phytologist, Volume 244, Issue 4, Page 1288-1302, November 2024.
Summary Resolving the position of roots in the whole‐plant hierarchy of drought‐induced xylem embolism resistance is fundamental for predicting when species become isolated from soil water resources. Published research generally suggests that roots are the most vulnerable organ of the plant vascular system, although estimates vary significantly ...

Insights into U‐to‐C RNA editing from the lycophyte Phylloglossum drummondii

The Plant Journal, Volume 119, Issue 1, Page 445-459, July 2024.
Significance Statement U‐to‐C RNA editing is only found in plants, and within plants, only in some hornworts, lycophytes and ferns. The unusual lycophyte Phylloglossum drummondii contains four U‐to‐C editing sites that can be matched with four putative U‐to‐C editing enzymes, making it a useful model for the study of this uncommon process.
