Brassinosteroids regulate plant growth through distinct signaling pathways in Selaginella and Arabidopsis.

PLoS ONE, 2013
Brassinosteroids (BRs) are growth-promoting steroid hormones that regulate diverse physiological processes in plants. Most BR biosynthetic enzymes belong to the cytochrome P450 (CYP) family.

Novel fern- and centipede-like Selaginella (Selaginellaceae) species and a new combination from South America

PhytoKeys, 2017
Two new Selaginella species (i.e. S. altheae Valdespino and S. squamulosa Valdespino) and a novel combination [i.e. S. philipsonii (Jermy & Rankin) Valdespino] from South America are proposed.

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

PLoS 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

BMC 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.

First record of Selaginella from Miocene amber [PDF]

Fossil Record
Among extant lycophytes, Selaginella (Selaginellaceae, spike mosses) is the most species-rich genus, with over 700 described species. The evolutionary history of this lycophyte genus dates back to the Carboniferous or even Devonian; however, amber ...

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

Plant 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
