FtsZ of Filamentous, Heterocyst-Forming Cyanobacteria Has a Conserved N-Terminal Peptide Required for Normal FtsZ Polymerization and Cell Division

Frontiers in Microbiology, 2018
Filamentous cyanobacteria grow by intercalary cell division, which should involve distinct steps compared to those producing separate daughter cells. The N-terminal region of FtsZ is highly conserved in the clade of filamentous cyanobacteria capable of ...

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, EarlyView.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

Locally adapted Arabidopsis thaliana accessions show transcriptomic plasticity in a multi‐timescale analysis of whole‐genome gene expression in a natural environment

Plant Biology, EarlyView.
Natural Arabidopsis thaliana accessions showed remarkable plasticity in both life‐cycle phenology and whole‐genome gene expression patterns in in natura field experiments. Nevertheless, local adaptation in fitness‐related life‐history traits can also be detected at the whole‐genome gene expression level.

How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta‐analysis

Journal of Ecology, Volume 113, Issue 10, Page 2875-2888, October 2025.
These results suggest that the fertilization effect of CO2 at the seedling stage may be limited when additional environmental stressors, such as drought, are present. The combined effect of drought, temperature and CO2 mainly resulted in additive effects, where each stressor independently influences plant performance rather than interacting to amplify ...

Characterization of TrxC, an Atypical Thioredoxin Exclusively Present in Cyanobacteria

Antioxidants, 2018
Cyanobacteria form a diverse group of oxygenic photosynthetic prokaryotes considered to be the antecessor of plant chloroplast. They contain four different thioredoxins isoforms, three of them corresponding to m, x and y type present in plant chloroplast,
