Exosome-Deficient Mutants Reveal Rare Promoter Upstream Transcripts (PROMPTs) in Arabidopsis
Research, The Plant Cell, The Plant Cell: In BriefIn 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.)
Plant Science Research WeeklyNitrogen (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)
Plant Science Research WeeklyA 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…
Roles for CHROMATIN REMODELING 4 in Arabidopsis floral transition (Plant Cell)
Plant Science Research WeeklyThe time at which flowers appear is critical for plant reproductive success. As such, the vegetative to reproductive growth transition is governed by several cues: environmental (photoperiod, temperature) and endogenous (gibberellins, age). Here, Sang et al. used an elegant forward-genetics approach…
The embryo sheath is an anti-adhesive structure that facilitates cotyledon emergence during germination in Arabidopsis ($) (Curr. Biol.)
Plant Science Research WeeklyThe embryo sheath is a glycoprotein structure formed during seed maturation in Arabidopsis thaliana. However, its function and its persistence after germination have been uncertain. Here, Doll et al. examined germination and seedling establishment of krs mutants deficient in the KERBEROS peptide that…
