Twin-Positive Motifs Function as Specific Plastid Targeting Signals

Precise trafficking of proteins to their proper destinations in the cell, whether to an organelle, a membrane, or the cytoplasm, is required for optimal cellular function. Because most plastid proteins are nucleus-encoded and translated in the cytoplasm, proper targeting and import relies on the presence…

Exosome-Deficient Mutants Reveal Rare Promoter Upstream Transcripts (PROMPTs) in Arabidopsis

In eukaryotes and archaea, protein-coding DNA is transcribed to messenger RNA (mRNA) via a preinitiation complex (PIC) composed of over 100 proteins, among them regulatory proteins, numerous transcription factors, and RNA polymerase II—the enzyme that produces precursor messenger RNA (pre-mRNA). Although…

Review. Signalling pathways underlying nitrogen-dependent changes in root system architecture: from model to crop species (J. Exp. Bot.)

Nitrogen (N) is one of the seventeen essential nutrients for a plant to complete its life cycle and is one of the most important determinants of productivity of various crops globally. Nitrate (NO3‑) and ammonium (NH4+) are the major plant-available forms of N. The spatiotemporal heterogeneity of N…

Hornwort genomes (Nature Plants)

A major update in plant genome information is taking place. Two independent groups have published genomes of hornwort species from the Anthoceros genus. Both papers arrive at similar conclusions supporting the model of a single “Setaphyta” clade, with hornworts sister to liverworts and mosses. These…
