20 de may. de 2011 · Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported.

To discover the full gene contents in S. moellendorffii and characterize their expression profiles, the study was designed to perform deep sequencing on RNA of differentiated tissues from S. moellendorffii. Root, stem and leaf samples of S. moellendorffii were first collected (Fig. 1), from which total RNA was isolated as described in Methods. Beca...
To analyze the transcriptome profile of S. moellendorffii and its gene models, we first filtered reads from three tissues and mapped them separately to the S. moellendorffii reference genome. About 105,111,858 (~65%) filtered reads (paired-end and directional) were mapped, covering 21,569 (96.8%) of the 22,285 annotated genes in S. moellendorffii g...
Alternative splicing (AS) is a common mechanism to generate transcript isoforms in eukaryotes, greatly increasing proteomic diversity with limited gene number. No alternative splicing events were reported previously for S. moellendorffii genes. In the current study, we used TopHat (version 2.1.0) to detect splice junction sites between exons of S....
The 7822 ncRNAs in S. moellendorffii (Additional file 2) were further analyzed. A set of long noncoding RNA (lncRNA) were identified using more strengthened criteria (Methods). As a result, 4422 lncRNAs were obtained from S. moellendorffii, and were classified into two groups based on their genomic location relative to coding genes: lncRNA in inter...
S. moellendorffii represents an ancient linage of vascular plants, which evolved primary vascular tissues over 400 million year ago. To investigate the gene contents and expression pattern associated with the development of vascular tissues, we compared and characterized the tissue-specifically expressed coding genes among the S. moellendorffii tis...
The lycophytes are primitive vascular plant, and occupy a key phylogenetic position in the evolution of green plants. The key components of signaling and transcriptional regulation in vascular development in flowering plants have been investigated and revealed in model plants like Arabidopsis [19, 42, 43]. By comparing those from S. moellendorffii ...

The spikemoss Selaginella moellendorffii has a genome size of only ~100Mbp, which is the smallest genome size of any plant reported. The sequence of the Selaginella genome by JGI provides scientists an important reference genome necessary for deciphering the evolution of biochemical, physiological and developmental processes unique to land plants.
20 de may. de 2011 · We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported.
Selaginella moellendorffii is a spikemoss. They belong to the subdivision of higher vascular plants called lycophytes, an ancient group of plants appeared around 410 million years ago. Selaginella moellendorffii is the first non-seeded plant genome reported, making it a key species for plant evolution studies. Taxonomy ID 88036.
