for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

A novel chloroplast gene reported for flagellate plants.
(American journal of botany, 2018-01)PREMISE OF THE STUDY:Gene space in plant plastid genomes is well characterized and annotated, yet we discovered an unrecognized open reading frame (ORF) in the fern lineage that is conserved across flagellate plants. METHODS:We ... -
A plant genetic network for preventing dysbiosis in the phyllosphere.
(Nature, 2020-04-08)The aboveground parts of terrestrial plants, collectively called the phyllosphere, have a key role in the global balance of atmospheric carbon dioxide and oxygen. The phyllosphere represents one of the most abundant habitats ... -
Fern genomes elucidate land plant evolution and cyanobacterial symbioses.
(Nature plants, 2018-07-02)Ferns are the closest sister group to all seed plants, yet little is known about their genomes other than that they are generally colossal. Here, we report on the genomes of Azolla filiculoides and Salvinia cucullata ... -
Horizontal transfer of an adaptive chimeric photoreceptor from bryophytes to ferns.
(Proceedings of the National Academy of Sciences of the United States of America, 2014-05)Ferns are well known for their shade-dwelling habits. Their ability to thrive under low-light conditions has been linked to the evolution of a novel chimeric photoreceptor--neochrome--that fuses red-sensing phytochrome and ... -
Horsetails and ferns are a monophyletic group and the closest living relatives to seed plants.
(Nature, 2001-02)Most of the 470-million-year history of plants on land belongs to bryophytes, pteridophytes and gymnosperms, which eventually yielded to the ecological dominance by angiosperms 90 Myr ago. Our knowledge of angiosperm phylogeny, ... -
Identifying multiple origins of polyploid taxa: a multilocus study of the hybrid cloak fern (Astrolepis integerrima; Pteridaceae).
(American journal of botany, 2012-11)PREMISE OF THE STUDY: Molecular studies have shown that multiple origins of polyploid taxa are the rule rather than the exception. To understand the distribution and ecology of polyploid species and the evolutionary significance ... -
Incongruence between primary sequence data and the distribution of a mitochondrial atp1 group II intron among ferns and horsetails.
(Molecular phylogenetics and evolution, 2005-09)Using DNA sequence data from multiple genes (often from more than one genome compartment) to reconstruct phylogenetic relationships has become routine. Augmenting this approach with genomic structural characters (e.g., intron ... -
Overcoming deep roots, fast rates, and short internodes to resolve the ancient rapid radiation of eupolypod II ferns.
(Systematic biology, 2012-05)Backbone relationships within the large eupolypod II clade, which includes nearly a third of extant fern species, have resisted elucidation by both molecular and morphological data. Earlier studies suggest that much of the ... -
Redox rhythm reinforces the circadian clock to gate immune response.
(Nature, 2015-07-23)Recent studies have shown that in addition to the transcriptional circadian clock, many organisms, including Arabidopsis, have a circadian redox rhythm driven by the organism's metabolic activities. It has been hypothesized ... -
The evolution of chloroplast genes and genomes in ferns.
(Plant molecular biology, 2011-07)Most of the publicly available data on chloroplast (plastid) genes and genomes come from seed plants, with relatively little information from their sister group, the ferns. Here we describe several broad evolutionary patterns ... -
Transcriptome-mining for single-copy nuclear markers in ferns.
(PloS one, 2013-01)BACKGROUND:Molecular phylogenetic investigations have revolutionized our understanding of the evolutionary history of ferns-the second-most species-rich major group of vascular plants, and the sister clade to seed plants. ... -
Unique expression of a sporophytic character on the gametophytes of notholaenid ferns (Pteridaceae).
(American journal of botany, 2012-06)PREMISE OF THE STUDY: Not all ferns grow in moist, shaded habitats; some lineages thrive in exposed, seasonally dry environments. Notholaenids are a clade of xeric-adapted ferns commonly characterized by the presence of ...
