A new preprint on tonoplast cytokinin riboside transporter important for plant-microbe interactions biorxiv.org/content/10.64898…

A tonoplast cytokinin riboside transporter gates intracellular hormone availability at the plant–...

Cytokinin ribosides are major mobile and precursor forms of cytokinins, but the mechanisms that control their intracellular availability remain poorly understood. Here, we identify Arabidopsis...

When stress drives you to kidnap: RACK1A sequesters FSD1 into stress granules during salt stress

Describing plants as sessile organisms may sound like a scientific revelation, but it simply means they have nowhere to go. However, it serves as a fitting
