Root research got a boost from Arabidopsis grown on Petri plants, but what do you do if you study something bigger, or want to see how roots grow in soil? Zheng et al. developed a new set of tools they call CREAMD-COFE [Core Root Excavation using Compressed-air (to extract the roots from soil), and Core…

Developmental programming, metabolism and plant growth are regulated by the circadian rhythm that integrates environmental signals and plant growth. In this paper, Romanowski et al. have used the RNAseq approach to determine post-transcriptional regulation in Arabidopsis thaliana, specifically alternate…

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),…
