The hidden life of unicellular red algae: discovery of a common sexual cycle unlocks a model lineage for eukaryotic evolution

From land plants to algae, the entire Archaeplastida supergroup traces its lineage back to a primary endosymbiotic event that occurred about 1.5 billion ye

The MrHY5-mru-miR396-MrGRF4 module regulates UV-B-induced quercetin biosynthesis in Chinese bayberry (Morella rubra cv. Biqi)

Abstract. Flavonols are important secondary metabolites that protect plants against UV-B stress. Although plant miRNAs can fine-tune abiotic stress respons

Tracking newly synthesised proteins in plants

Protein synthesis rate is distinct from steady-state protein abundance and must be measured independently to understand how cells regulate protein levels and respond to environments. Technologies used to predict or directly quantify protein synthesis include ribosome profiling, radioactive and stable isotope labelling, and bioorthogonal noncanonical amino acid tagging (BONCAT). Here, we emphasise BONCAT’s potential in plants, which, when combined with click-chemistry, enables the detection, enrichment, and characterisation of newly synthesised proteins themselves. We summarise lessons from BONCAT applications in cell-free systems, microbes, mammalian cells, and animals and evaluate its potential in plants. Establishing robust BONCAT approaches in plants can advance studies in proteome regulation, stress responses, development, circadian biology, and plant–microbe interactions.

Water flow within and towards plant roots—a new concurrent solution

Abstract. Various analytical models that calculate the water flow either around or inside plant roots are available, but a combined analytical solution has
