Krynická et al. uncover the critical role of the FtsH1/3 protease complex in the acclimation of a model cyanobacterium to nutrient stress. Plant Cell https://doi.org/10.1105/tpc.19.00411 By Vendula Krynická1,2 and Philip J. Jackson3,4  1Centre Algatech, Institute of Microbiology of the Czech…

In a new Perspective by Wurtzel et al., the authors lay out SynBio’s tremendous potential to transform agriculture. Consider how we might leverage the “vast design space that plants have not occupied.” As an example, plants employ two pathways to fix carbon, and prokaryotes another six, but scientists…

Although the first signaling peptide identified in plants, systemin, is involved in stress responses, developmentally important peptide signals have largely occupied the limelight. This Tansley Review by Chen et al. summarizes recent insights into peptides with a role in stress responses: wounding, pathogen…

Drawing on more than 15 years of improvements, Nakano et al. have released public websites and resources for data access, display, and analysis of plant small RNAs, from Arabidopsis to wheat and with many crops and model species represented. The tools can analyze, integrate and display the abundance…

RNA G quadruplex (RG4) structures that include two or more layers of G-quartets can form in guanine-rich RNA sequences. These structures are known exist in vitro and are proposed to form in vivo as well. However, there is no direct evidence from plants showing the presence of these structures in vivo. …

The Zygnematophyceae are the green algae that are most closely related to land plants. Some species in this clade are considered subaerial, meaning that they can live under air (as opposed to under water). The green films you see on tree trunks and walls are often Zygnematophycaea. Several new insights…

The availability of charophyte algae genomic information is helping to understand how the plant transition to a terrestrial environment occurred at the molecular level. Here, Cheng et al. are releasing two genomes from the Zygnematophyceae clade (Spirogloea muscicola and Mesotaenium endlicherianum),…

The origins of ABA signaling have long been puzzling. Green algae make ABA but don't respond to it, and ABA receptors have appeared to be missing from their genomes. Reccently, Sun et al. identified a gene encoding an ortholog of PYL family of ABA receptor proteins in the transcriptome of an alga from…
