Origins and Evolution of WUSCHEL‐Related Homeobox Protein Family in Plant Kingdom

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
WUSCHEL‐related homeobox (WOX) is a large group of transcription factors specifically found in plants. WOX members contain the conserved homeodomain essential for plant development by regulating cell division and differentiation. However, the evolutionary relationship of WOX members in plant kingdom remains to be elucidated.

Molecular evolution of glutamine synthetase II: Phylogenetic evidence of a non-endosymbiotic gene transfer event early in plant evolution

BMC Evolutionary Biology, 2010
Background Glutamine synthetase (GS) is essential for ammonium assimilation and the biosynthesis of glutamine. The three GS gene families (GSI, GSII, and GSIII) are represented in both prokaryotic and eukaryotic organisms.

Conservation and Variability of Synaptonemal Complex Proteins in Phylogenesis of Eukaryotes

International Journal of Evolutionary Biology, Volume 2014, Issue 1, 2014., 2014
The problems of the origin and evolution of meiosis include the enigmatic variability of the synaptonemal complexes (SCs) which, being morphology similar, consist of different proteins in different eukaryotic phyla. Using bioinformatics methods, we monitored all available eukaryotic proteomes to find proteins similar to known SC proteins of model ...

Plant MicroRNA Prediction by Supervised Machine Learning Using C5.0 Decision Trees

Journal of Nucleic Acids, Volume 2012, Issue 1, 2012., 2012
MicroRNAs (miRNAs) are nonprotein coding RNAs between 20 and 22 nucleotides long that attenuate protein production. Different types of sequence data are being investigated for novel miRNAs, including genomic and transcriptomic sequences. A variety of machine learning methods have successfully predicted miRNA precursors, mature miRNAs, and other ...

Additions to the Fern Flora of Niue (Polynesia): First Records of Ophioglossum lusitanicum L., Ophioderma falcatum (C.Presl) O.Deg. and Psilotum complanatum Sw. and the Disjunct Occurrence of Ophioderma intermedium (Hook.) Nishida

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
During recent field survey for threatened and uncommon vascular plants in Niue, four ferns were collected and confirmed as additions to the indigenous flora. Ophioderma intermedium (Hook.) Nishida and O. falcatum (C.Presl) O.Deg. were collected from terrestrial habitats in primary tropical forest.

A Whole Chloroplast Genome Phylogeny of Diploid Species of Isoëtes (Isoëtaceae, Lycopodiophyta) in the Southeastern United States [PDF]

Castanea, 2018
ABSTRACT  The phylogeny of closely related species of Isoetes has been difficult to infer using morphological or molecular data. The southeastern United States exhibits among the highest diversity of Isoetes species, which likely are the result of a relatively recent radiation.
