Review: In vitro analytical approaches to study plant ligand-receptor interactions (Plant Physiol)
Plant Science Research WeeklyIt seems every other paper shows a nice diagram of a signaling cascade that includes a receptor interacting with its ligand. However, sometimes these diagrams are little more than speculation or guesswork. It’s not always easy to figure out if this interaction is real. Here, Sandoval and Santiago review…
Review: Evolution of plant hormone response pathways ($) (Annu. Rev. Plant Biol.)
Plant Science Research WeeklySpatio-temporal action of hormones is essential for proper growth and development of plants. In this review, Blázquez et al. discuss the evolution of the shared features of signaling pathways of different plant hormones. Auxin, jasmonic acid, gibberellic acid, and strigolactone signaling pathways…
Review: Targeting root ion uptake kinetics to increase plant productivity and nutrient use efficiency (Plant Physiol.)
Plant Science Research WeeklyRoots anchor plants and take up water, but one of their most important and complex functions is to bring a large number of different essential nutrients into the plant. Root architecture affects and is affected by nutrient uptake, but ultimately uptake is largely controlled by membrane-bound ion transporters.…
COP1 destabilizes DELLA proteins in Arabidopsis (bioRxiv)
Plant Science Research WeeklyThe canonical model of gibberellic acid (GA) signaling pathway includes the recognition of the hormone by the receptor GID1 and the further degradation of the DELLA proteins by the proteasome. In this paper, Blanco-Touriñan et al. observed in Arabidopsis that the DELLA protein REPRESSOR OF ga1-3 (RGA)…
The maize heterotrimeric G protein β subunit controls shoot meristem development and immune responses ($) (PNAS)
Plant Science Research WeeklyHeterotrimeric G proteins transduce signals between receptors and downstream factors. Previous genetic studies have shown diverse roles for these proteins based on loss-of-function phenotypes; for example mutations in Arabidopsis Gα and Gβ subunits both lead to enlarged shoot apical meristems. Wu et…
High productivity in hybrid-poplar plantations without isoprene emission to the atmosphere ($) (PNAS)
Plant Science Research WeeklyMany trees emit isoprene (C5H8, a small volatile carbon compound) during hot weather, and isoprenes have been shown to help trees tolerate short bursts of high temperatures (heat flecks). Isoprenes are not themselves harmful, but are reactive and can lead to the production of high levels of ground-level…
Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy (eLIFE)
Plant Science Research WeeklyAdvances in microscopy have greatly informed our understanding of fundamental plant processes, but the germline cells in flowers have been hard to image as they are tiny and embedded within other tissues. Valuchova et al. present a method using light sheet fluorescence microscopy that allows live cell…
