The Ectocarpus genome and the independent evolution of multicellularity in brown algae
TLDR
The Ectocarpus genome sequence represents an important step towards developing this organism as a model species, providing the possibility to combine genomic and genetic approaches to explore these and other aspects of brown algal biology further.

Copper stress induces biosynthesis of octadecanoid and eicosanoid oxygenated derivatives in the brown algal kelp Laminaria digitata.
TLDR
The results suggest that lipid peroxidation participates in the toxic effects of copper and that lipidPeroxidation derivatives may regulate protective mechanisms by employing plant-like octadecanoid signals but also eicosanoid oxylipins which are absent in vascular plants.

Copper stress proteomics highlights local adaptation of two strains of the model brown alga Ectocarpus siliculosus
TLDR
The occurrence of two different phenotypes within two distinct E. siliculosus strains studied at the physiological and proteomic levels strongly suggest that persistent copper stress may represent a selective force leading to the development of strains genetically adapted to copper contaminated sites.

TWO‐DIMENSIONAL GEL ELECTROPHORESIS ANALYSIS OF BROWN ALGAL PROTEIN EXTRACTS 1
TLDR
The protocol, which includes an initial step to remove salts from the algal tissues, allowed the use of highly resolving two‐dimensional gel electrophoresis (2‐DE) protein analyses, providing the opportunity to unravel potentially novel physiological processes unique to this group of marine organisms.

Transcriptomic and metabolomic analysis of copper stress acclimation in Ectocarpus siliculosus highlights signaling and tolerance mechanisms in brown algae
TLDR
Comparisons with data from green plants indicate that some processes involved in Cu and oxidative stress response are conserved across these two distant lineages, and underlines the potential to discover new components and molecular interactions unique to these organisms.

Glutaredoxin GRXS17 Associates with the Cytosolic Iron-Sulfur Cluster Assembly Pathway1[OPEN]
TLDR
The data suggest that plant cytosolic monothiol GRXs associate with the CIA complex, as in other eukaryotes, and contribute to, but are not essential for, the correct functioning of client Fe-S proteins in unchallenged conditions.

bHLH-PAS protein RITMO1 regulates diel biological rhythms in the marine diatom Phaeodactylum tricornutum
TLDR
Daily oscillations of gene expression and cell fluorescence in the diatom Phaeodactylum tricornutum, which persist in the absence of external timing cues are reported, demonstrating the existence of an endogenous circadian clock in diatoms.

Breaking Bad News: Dynamic Molecular Mechanisms of Wound Response in Plants
TLDR
This review aims to provide a broad overview of the molecular mechanisms underlying the fate of damaged cells and damage recognition in plants and places special emphasis on the spatiotemporal dimension in order to obtain a mechanistic understanding of wound signaling in plants.

The RING E3 Ligase KEEP ON GOING Modulates JASMONATE ZIM-DOMAIN12 Stability1[OPEN]
TLDR
JAZ12 was characterized, encoded by a highly expressed JAZ gene, and found JAZ12 to interact with SCFCOI1 components, matching with observed in vivo ubiquitination and with rapid degradation after treatment with JA.

The transcriptional repressor complex FRS7-FRS12 regulates flowering time and growth in Arabidopsis
TLDR
A molecular machinery that controls the photoperiodic regulation of flowering and growth and offer insight into how plants adapt to seasonal changes is revealed.
