Effect of sulfate availability on phytoplankton stoichiometry

open access: yesJournal of Phycology, EarlyView.
Abstract Sulfur (S) is a key element in multiple metabolic pathways of phytoplankton cells. The effect of S availability on phytoplankton elemental quotas and stoichiometry has been addressed in few studies, using a limited number of species and with contradictory results.

Tracing the biogeographic history of the world's most isolated insular floras

open access: yesJournal of Systematics and Evolution, EarlyView.
We inferred the spatio–temporal colonization histories of seven vascular plant lineages (Acaena magellanica, Austroblechnum penna‐marina, Azorella selago, Colobanthus kerguelensis, Notogrammitis crassior, Polystichum marionense, Pringlea antiscorbutica) using phylogenetic, divergence time estimation, and Bayesian Island Biogeographic analyses.

Inorganic carbon levels regulate growth via SigC signaling cascade in cyanobacteria

open access: yesNew Phytologist, EarlyView.
Summary Cyanobacterial growth depends on inorganic carbon (Ci; CO2 and bicarbonate) concentration, but mechanism(s) adjusting photosynthesis and growth according to Ci remain unclear. ΔrpoZ cells lacking the ω subunit of the RNA polymerase (RNAP) show a unique high‐CO2 lethal phenotype in Synechocystis sp. PCC 6803.

Authentication of Herbal Medicines Dipsacus asper and Phlomoides umbrosa Using DNA Barcodes, Chloroplast Genome, and Sequence Characterized Amplified Region (SCAR) Marker

open access: yesMolecules, 2018
Dried roots of Dipsacus asper (Caprifoliaceae) are used as important traditional herbal medicines in Korea. However, the roots are often used as a mixture or contaminated with Dipsacus japonicus in Korean herbal markets.

Functional study of Phaeodactylum tricornutum Seipin highlights specificities of lipid droplets biogenesis in diatoms

open access: yesNew Phytologist, EarlyView.
Summary Diatoms are a major phylum of microalgae, playing crucial ecological roles. They derive from secondary endosymbiosis, leading to a complex intracellular architecture. Their ability to store oil in lipid droplets (LDs) upon unfavourable conditions has raised interest for applications, in particular biofuels, yet Lipid Droplet (LD) biogenesis ...

Seed Dormancy Involves a Transcriptional Program That Supports Early Plastid Functionality during Imbibition

open access: yesPlants, 2018
Red rice fully dormant seeds do not germinate even under favorable germination conditions. In several species, including rice, seed dormancy can be removed by dry-afterripening (warm storage); thus, dormant and non-dormant seeds can be compared for the ...
