Time-resolved oxidative signal convergence across the algae-embryophyte divide

The paper studies stress response kinetics in early land plants and their algal relatives using multi-omics data to infer ancient gene regulatory networks.

Metabolic rewiring compensates for the loss of glutamate and aspartate biosynthesis in Bacillus subtilis

This study identifies a non-canonical fumarate-based ammonium assimilation pathway in B. subtilis that compensates for glutamate and aspartate biosynthesis defects.

Phylogenomic insights into the first multicellular streptophyte

This study presents a phylogenomic analysis of Klebsormidiophyceae, revealing a novel four-order system and estimating the origin of the first multicellular streptophytes over 900 million years ago.

Chromosome-level genomes of multicellular algal sisters to land plants illuminate signaling network evolution

The paper sequenced four Zygnematophyceae algal genomes to study signaling network evolution, finding expanded genes for multicellularity and environmental response.

Environmental gradients reveal stress hubs predating plant terrestrialization

The paper uses RNAseq and photophysiological data from Mesotaenium under environmental stress to identify stress response hubs in algae, suggesting ancient molecular programs predating plant terrestrialization.

A phylogenomically informed five-order system for the closest relatives of land plants

The paper presents a new five-order system for Zygnematophyceae based on phylogenomic analysis of a filamentous green alga, revealing five independent origins of filamentous growth.

Underwater CAM photosynthesis elucidated by Isoetes genome

This study investigates underwater CAM in Isoetes taiwanensis using genome and RNA-seq data, identifying key differences in carboxylation and circadian control compared to terrestrial CAM.

The evolution of the phenylpropanoid pathway entailed pronounced radiations and divergences of enzyme families

This study shows that enzyme families in the phenylpropanoid pathway underwent radiations and divergences in land plants and their algal relatives, suggesting evolutionary versatility in specialized metabolism.

A molecular timescale for the origin of red algal-derived plastids

The paper establishes a timeframe for the origin of red algal-derived plastids using phylogenomic data and molecular clock analyses, showing that serial endosymbiosis hypotheses are chronologically possible.

Phylogenomic Insights into the Origin of Primary Plastids

This study investigates the monophyly of Archaeplastida hosts using phylogenomic datasets to understand the origin of primary plastids.

Abiotic environmental adaptation in vertebrates is characterized by functional genomic constraint

The paper identifies genes involved in abiotic environmental adaptation across vertebrates and finds evidence of functional genomic constraint and recurrent gene use.
