LEAFY COTYLEDON1, a key regulator of seed development, is expressed in vegetative and sexual propagules of Selaginella moellendorffii. [PDF]

open access: yesPLoS ONE, 2013
LEAFY COTYLEDON1 (LEC1) is a central regulator of seed development that plays a key role in controlling the maturation phase during which storage macromolecules accumulate and the embryo becomes tolerant of desiccation. We queried the genomes of seedless

Comparative transcriptome analysis suggests convergent evolution of desiccation tolerance in Selaginella species

open access: yesBMC Plant Biology, 2020
Background Desiccation tolerant Selaginella species evolved to survive extreme environmental conditions. Studies to determine the mechanisms involved in the acquisition of desiccation tolerance (DT) have focused on only a few Selaginella species.

Extreme plastid RNA editing may confound phylogenetic reconstruction: A case study of Selaginella (lycophytes)

open access: yesPlant Diversity, 2020
Cytidine-to-uridine (C-to-U) RNA editing is common in coding regions of organellar genomes throughout land plants. In most cases RNA editing alters translated amino acids or creates new start codons, potentially confounds phylogenetic reconstructions. In
