Open AccessGenomes of multicellular algal sisters to land plants illuminate signaling network evolution
Zygnematophyceae are the algal sisters of land plants. Here we sequenced four genomes of filamentous Zygnematophyceae, including chromosome-scale assemblies for three strains of Zygnema circumcarinatum. We inferr...

Open AccessEnvironmental gradients reveal stress hubs pre-dating plant terrestrialization
Plant terrestrialization brought forth the land plants (embryophytes). Embryophytes account for most of the biomass on land and evolved from streptophyte algae in a singular event. Recent advances have unravel...

Open AccessAccessible versatility underpins the deep evolution of plant specialized metabolism
The evolution of several hallmark traits of land plants is underpinned by phytochemical innovations. The specialized metabolism of plants can appear like a teeming chaos that has yielded an ungraspable array o...

Open AccessSubmergence of the filamentous Zygnematophyceae Mougeotia induces differential gene expression patterns associated with core metabolism and photosynthesis
The streptophyte algal class Zygnematophyceae is the closest algal sister lineage to land plants. In nature, Zygnematophyceae can grow in both terrestrial and freshwater habitats and how they do this is an imp...

Open AccessUnderwater CAM photosynthesis elucidated by Isoetes genome
To conserve water in arid environments, numerous plant lineages have independently evolved Crassulacean Acid Metabolism (CAM). Interestingly, Isoetes, an aquatic lycophyte, can also perform CAM as an adaptation t...

Open AccessAnthoceros genomes illuminate the origin of land plants and the unique biology of hornworts
Hornworts comprise a bryophyte lineage that diverged from other extant land plants >400 million years ago and bears unique biological features, including a distinct sporophyte architecture, cyanobacterial symb...

Open AccessHeterotrimeric G–proteins in Picea abies and their regulation in response to Heterobasidion annosum s.l. infection
Heterotrimeric G-proteins are important signalling switches, present in all eukaryotic kingdoms. In plants they regulate several developmental functions and play an important role in plant-microbe interactions...
